1 CHEMISTRY AND CHEMISTWithout chemistry our lives would beunrecognisable, for chemistry is at work all aroundus. Think what life would be like without chemistry- there would be no plastics, no electricity and noprotective paints for our homes. There would be no synthetic fibres to clothe us and no fertilisers to help us produce enough food. We wouldn‟t be able to travel because there would be no metal, rubber or fuel for cars, ships and aeroplane. Our lives would be changed considerably without telephones, radio, television or computers, all of which depend on chemistry for the manufacture of their parts. Life expectancy would be much lower, too, as there would be no drugs to fight disease.Chemistry is at the forefront of scientific adventure, and you could make your own contribution to the rapidly expanding technology we are enjoying. Take some of the recent academic research: computer graphics allow us to predict whether small molecules will fit into or react with larger ones - this could lead to a whole new generation of drugs to control disease; chemists are also studying the use of chemicals to trap the sun‟s energy and to purify sea water; they are also investigating the possibility of using new ceramic materials to replace metals which can corrode.Biotechnology is helping us to develop new sources of food and new ways of producing fuel, as well as producing new remedies for the sick. As the computer helps us to predict and interpret results from the test tube, the speed, accuracy and quality of results is rapidly increasing - all to the benefit of product development.It is the job of chemists to provide us with new materials to take us into the next century, and by pursuing the subject, you could make your positive contribution to society.Here are some good reasons for choosing chemistry as a career.Firstly, if you have an interest in the chemical sciences, you can probably imagine taking some responsibility for the development of new technology. New ideas and materials are constantly being used in technology to improve the society in which we live. You could work in a field where research and innovation are of primary importance to standards of living, so you could see the practical results of your work in every day use.Secondly, chemistry offers many career opportunities, whether working in a public service such as a water treatment plant, or high level research and development in industry. Your chemistry-based skills and experience can be used, not only in many different areas within the chemical industry, but also as the basis for a more general career in business.1 As a qualification, chemistry is highly regarded as a sound basis for employment.You should remember that, as the society we live in becomes more technically advanced, the need for suitably qualified chemists will also increase. Although chemistry stands as a subject in its own right, it acts as the bond between physics and biology. Thus, by entering the world of chemistry you will be equipping yourself to play a leading role in the complex world of tomorrow.Chemistry gives you an excellent training for many jobs, both scientific and non-scientific. To be successful in the subject you need to be able to think logically, and be creative, numerate, and analytical. These skills are much sought after in many walks of life, and would enable you to pursue a career in, say, computing and finance, as well as careers which use your chemistry directly.Here is a brief outline of some of the fields chemists work in:Many are employed in the wealth-creating manufacturing industries - not just oil, chemical and mining companies, but also in ceramics, electronics and fibres. Many others are in consumer based industries such as food, paper and brewing; or in service industriessuch as transport, health and water treatment.In manufacturing and service industries, chemists work in Research and Development to improve and develop new products, or in Quality Control, where they make sure that the public receives products of a consistently high standard.Chemists in the public sector deal with matters of public concern such as food preservation, pollution control, defence, and nuclear energy. The National Health Service also needs chemists, as do the teaching profess ion and the Government‟s research and advisory establishments.Nowadays, chemists are also found in such diverse areas as finance, law and politics, retailing, computing and purchasing. Chemists make good managers, and they can put their specialist knowledge to work as consultants or technical authors. Agricultural scientist, conservationist, doctor, geologist, meteorologist, pharmacist, vet ... the list of jobs where a qualification in chemistry is considered essential is endless. So even if you are unsure about what career you want to follow eventually, you can still study chemistry and know that you‟re keeping your options open.What Do Chemistry Graduates Do?Demand for chemists is high, and over the last decade opportunities for chemistry graduates have been increasing. This is a trend that is likely to continue. Chemistry graduates are increasingly sought after to work in pharmaceutical, oil, chemical, engineering, textile and metal companies, but the range of opportunities also spans the food industry, nuclear fuels, glass and ceramics, optical and photographic industries, hospitals and the automotive industry. Many graduates begin in scientific research, development and design, but over the years, about half change, into fields such as sales, quality control, management, or consultancy. Within the commercial world it is recognised that, because of the general training implicit in a chemistry course, chemistry graduates are particularly adaptable and analytical - making them attractive to a very broad spectrum of employers. There has been a growth of opportunity for good chemistry graduates to move into the financial world, particularly in accountancy, retail stores, and computer software houses.（Summarized from: A brief of the Royal Society of Chemistry,1992）2 NOMENCLATURE OF INORGANICCOMPOUNDSNaming elementsThe term element refers to a pure substance with atoms all of a single kind. At present 107 chemical elements are known. For most elements the symbol is simply the abbreviated form of the English name consisting of one or two letters, for example:oxygen = O nitrogen = N magnesium = MgSome elements, which have been known for a long time, have symbols based on their Latin names, for example:iron = Fe (ferrum) copper = Cu (cuprum) lead = Pb (Plumbum)A few elements have symbols based on the Latin name of one of their compounds, the elements themselves having been discovered only in relatively recent times1, for example: sodium = Na (natrium = sodium carbonate)potassium = K (kalium = potassium carbonate)A listing of some common elements may be found in Table 1.Naming Metal Oxides, Bases and SaltsA compound is a combination of positive and negative ions in the proper ratio to give a balanced charge and the name of the compound follows from names of the ions, for example, NaCl, is sodium chloride; Al(OH)3is aluminium hydroxide; FeBr2is iron (II) bromide or ferrous bromide; Ca(OAc)2is calcium acetate; Cr2(SO4)3is chromium (III) sulphate or chromic sulphate, and so on. Table 3 gives some examples of the naming of metal compounds. The name of the negative ion will need to be obtained from Table 2.Negative ions, anions, may be monatomic or polyatomic. All monatomic anions have names ending with -ide. Two polyatomic anions which also have names ending with -ide are the hydroxide ion, OH-, and the cyanide ion, CN-.Many polyatomic anions contain oxygen in addition to another element. The number of oxygen atoms in such oxyanions is denoted by the use of the suffixes -ite and -ate, meaning fewer and more oxygen atoms, respectively. In cases where it is necessary to denote more than two oxyanions of the same element, the prefixes hypo- and per-, meaning still fewer and still more oxygen atoms, respectively, may be used, for example,hypochlorite ClO-Chlorite ClO2-chlorate ClO3-perchlorate ClO4-Naming Nonmetal OxidesThe older system of naming and one still widely used employs Greek prefixes for both the number of oxygen atoms and that of the other element in the compound 2. The prefixes used are (1) mono-, sometimes reduced to mon-, (2) di-, (3) tri-, (4) tetra-, (5) penta-, (6) hexa-, (7) hepta-, (8) octa-, (9) nona- and (10) deca-. Generally the letter a is omitted from the prefix (from tetra on ) when naming a nonmetal oxide and often mono- is omitted from the name altogether.The Stock system is also used with nonmetal oxides. Here the Roman numeral refers to the oxidation state of the element other than oxygen.In either system, the element other than oxygen is named first, the full name being used, followed by oxide 3. Table 4 shows some examples.Naming AcidsAcid names may be obtained directly from a knowledge of Table 2 by changing the name of the acid ion (the negative ion ) in the Table 2 as follows:The Ion in Table 2Corresponding Acid-ate-ic-ite-ous-ide-icExamples are:Acid Ion Acidacetate acetic acidperchlorate perchloric acidbromide hydrobromic acidcyanide hydrocyanic acidThere are a few cases where the name of the acid is changed slightly from that of the acid radical; for example, H2SO4 is sulphuric acid rather than sulphic acid. Similarly, H3PO4 is phosphoric acid rather than phosphic acid.Naming Acid and Basic Salt and Mixed SaltsA salt containing acidic hydrogen is termed an acid salt.A way of naming these salts is to call Na 2HPO4disodiumhydrogen phosphate and NaH2PO4sodium dihydrogenphosphate. Historically, the prefix bi- has been used innaming some acid salts; in industry, for example, NaHCO3 iscalled sodium bicarbonate and Ca(HSO3)2 calcium bisulphite.Bi(OH)2NO3, a basic salt, would be called bismuthdihydroxynitrate. NaKSO4, a mixed salt, would be calledsodium potassium sulphate.3 NOMENCLATURE OF ORGANIC COMPOUNDSA complete discussion of definitive rules of organic nomenclature would require more space than can be allotted in this text. We will survey some of the more common nomenclature rules, both IUPAC and trivial.AlkanesThe names for the first twenty continuous-chain alkanes are listed in Table 1.Alkenes and AlkynesUnbranched hydrocarbons having one double bond are named in the IUPAC system by replacing the ending -ane of the alkane name with -ene. If there are two or more double bonds, the ending is -adiene, -atriene, etc.Unbranched hydrocarbons having one triple bond are named by replacing the ending -ane of the alkane name with -yne. If there are two or more triple bonds, the ending is -adiyne, -atriyne etc. Table 2 shows names for some alkyl groups, alkanes, alkenes and alkynes.The PrefixesIn the IUPAC system, alkyl and aryl substituents and many functional groups are named as prefixes on the parent (for example, iodomethane). Some common functional groups named as prefixes are listed in Table 3.In simple compounds, the prefixes di-, tri-, tetra-, penta-, hexa-, etc. are used to indicate the number of times a substituent is found in the structure: e.g., dimethylamine for(CH3)2NH or dichloromethane for CH2Cl2.In complex structures, the prefixes bis-, tris-, and tetrakis- are used: bis- means two of a kind; tris-, three of a kind; and tetrakis-, four of a kind. [(CH3)2N]2is bis(dimethylamino) and not di(dimethylamino).Nomenclature Priority of Functional GroupsIn naming a compound, the longest chain containing principal functional group is considered the parent. The parent is numbered from the principal functional group to the other end, the direction being chosen to give the lowest numbers to the substituents. The entire name of the structure is then composed of (1) the numbers of the positions of the substituts (and of the principal functional group, if necessary); (2) the names of the substituts;(3) the name of the parent.The various functional groups are ranked in priority as to which receives the suffix name and the lowest position number1.A list of these priorities is given in Table 4.*-CKetonesIn the systematic names for ketones, the -e of the parent alkane name is dropped and -one is added. A prefix number is used if necessary.In a complex structure, a ketone group my be named in IUPAC system with the prefix oxo-. (The prefix keto- is also sometimes encountered.)AlcoholsThe names of alcohols may be: (1) IUPAC; (2) trivial; or, occasionally, (3) conjunctive. IUPAC names are taken from the name of the alkane with the final -e changed to -ol. In the case of polyols, the prefix di-, tri- etc. is placed just before -ol, with the position numbers placed at the start of the name, if possible, such as, 1,4-cyclohexandiol. Names for some alkyl halides, ketones and alcohols are listed in Table 5.EthersEthers are usually named by using the names of attached alkyl or aryl groups followed by the word ether. (These are trivial names.) For example, diethyl ether.In more complex ethers, an alkoxy- prefix may be used. This is the IUPAC preference, such as 3-methoxyhexane. Sometimes the prefix- oxa- is used.AminesAmines are named in two principal ways: with -amine as the ending and with amino- as a prefix. Names for some ethers and amines can be found in Table 6.Carboxylic AcidsThere are four principal types of names for carboxylic acids: (1) IUPAC; (2)trivial;(3)carboxylic acid; and (4)conjunctive. Trivial names are commonly used.AldehydesAldehydes may be named by the IUPAC system or by trivial aldehyde names. In the IUPAC system, the -oic acid ending of the corresponding carboxylic acid is changed to -al, such as hexanal. In trivial names, the -ic or -oic ending is changed to -aldehyde, such as benzaldehyde. Table 7 gives a list of commonly encountered names for carboxylic acids and aldehydes.Esters and Salts of Carboxylic AcidsEsters and salts of carboxylic acids are named as two words in both systematic and trivial names. The first word of the name is the name of the substituent on the oxygen. The second word of the name is derived from the name of the parent carboxylic acid with the ending changed from -ic acid to -ate.AmidesIn both the IUPAC and trivial systems, an amide is named by dropping the -ic or -oic ending of the corresponding acid name and adding -amide, such as hexanamide (IUPAC) and acetamide (trivial).Acid AnhydridesAcid anhydrides are named from the names of the component acid or acids with the word acid dropped and the word anhydride added, such as benzoic anhydride.The names for some esters, amides and anhydrides are shown in Table 8.Acid HalidesAcid halides are named by changing the ending of the carboxylic acid name from -ic acid to -yl plus the name of the halide, such as acetyl chloride.Some names of aryl compounds and aryls are as follows:benzenephenylbenzylarylbenzoic acid4. Introduction to Chemistry Department of FloridaUniversityProgram of StudyThe Department of Chemistry offers programs of study leading to the M.S. and Ph.D. degrees. Students may elect studies in analytical, inorganic, organic, and physical chemistry. Specialty disciplines, such as chemical physics and quantum, bioorganic, polymer, radiation, and nuclear chemistry, are available within the four major areas.The M.S. and Ph.D. degree requirements include a course of study, attendance at and presentation of a series of seminars, and completion and defense of a research topic worthy of publication1. Candidates for the Ph.D. degree must also demonstrate a reading ability of at least one foreign language and show satisfactory performance on a qualifying examination. The M.S. degree is not a prerequisite for the Ph.D. degree. A nonthesisdegree program leading to the M.S.T. degree is offered for teachers.Students are encouraged to begin their research shortly afterselecting a research director, who is the chairman of the supervisory committee that guides the student through a graduate career.Research FacilitiesThe chemistry department occupies 111,000 square feet of space in four buildings: Leigh Hall, the Chemical Research Building, Bryant Hall, and the Nuclear Science Building. Plans for a 65,000-square-foot addition to Leigh Hall are being prepared. A new central science library is located near the chemistry facilities. The University library system holds more than 2.2 million volumes.The major instrumentation includes ultraviolet-visible, infrared, fluorescence, Roman, nuclear magnetic resonance, electron spin resonance, X-ray, ESCA, and mass spectrometers. Many are equipped with temperature-control and Fourier-transform attachments, and some have laser sources. Data-storage and data-acquiring minicomputers are interfaced to some of the instruments, such as the recently constructed quadrupole resonance mass spectrometer. The chemistry department has V AX-11/780 and V AX-11/750 computers as well as multiple terminals connected to IBM machines in the main computer centre on campus.The departmental technical services include two well-equipped stockrooms and glassblowing, electronics, and machine shops to assist in equipment design, fabrication, and maintenance.Financial AidMost graduate students are given financial support in the form of teachingand research assistantships. Stipends range from $9400 - 11,000 for the1986-87 calendar year. State residents and assistantship holders pay in-statefees of about $1400 per calendar year. A limited number of full orsupplemental fellowships are available for superior candidates.Cost of StudyIn 1985-86, in-state students paid a registration fee of $48.62, per credit hour for each semester, out-of-state students paid an additional $ 94.50 ($ 143.12 per credit hour each semester). A small increase in fees is expected for 1986-87.5 ENVIRONMENTAL POLLUTIONWith the coming of the Industrial Revolution the environmentalpollution increased alarmingly. Pollution can be defined as an undesirablechange in the physical, chemical, or biological characteristics of the air, water,or land that can harmfully affect health, survival, or activities of humans orother living organisms. There are four major forms of pollution - waste onland, water pollution (both the sea and inland waters), pollution of the atmosphere and pollution by noise.Land can be polluted by many materials. There are two major types of pollutants: degradable and nondegradable. Examples of degradable pollutantsare DDT and radioactive materials. DDT can decompose slowly buteventually are either broken down completely or reduced to harmless levels. For example, it typically takes about 4 years for DDT in soil to be decomposed to 25 percent of the original level applied. Some radioactive materials that give off harmful radiation, such as iodine-131, decay to harmless pollutants. Others, such as plutonium-239 produced by nuclear power plants, remains at harmful levels for thousands to hundreds of thousands of years.Nondegradable pollutants are not broken down by natural processes. Examples ofnondegradable pollutants are mercury, lead and some of their compounds and some plastics. Nondegradable pollutants must be either prevented from entering the air, water, and soil or kept below harmful levels by removal from the environment.Water pollution is found in many forms. It is contamination of water with city sewage and factory wastes; the runoff of fertiliser and manure from farms and feed lots; sudsy streams; sediment washed from the land as a result of storms, farming, construction and mining; radioactive discharge from nuclear power plants; heated water from power and industrial plants; plastic globules floating in the world‟s oceans; and female sex hormones entering water supplies through the urine of women taking birth control pills.Even though scientists have developed highly sensitive measuringinstruments, determining water quality is very difficult. There are a largenumber of interacting chemicals in water, many of them only in trace amounts.About 30,000 chemicals are now in commercial production, and each yearabout 1,000 new chemicals are added. Sooner or later most chemicals end up in rivers, lakes, and oceans. In addition, different organisms have different ranges of tolerance and threshold levels for various pollutants. To complicate matters even further, while some pollutants are either diluted to harmless levels in water or broken down to harmless forms by decomposers and natural processes, others (such as DDT, some radioactive materials, and some mercury compounds) are biologically concentrated in various organisms1.Air pollution is normally defined as air that contains one or more chemicals in high enough concentrations to harm humans, other animals, vegetation, or materials. There are two major types of air pollutants. A primary air pollutant is a chemical added directly to the air that occurs in a harmful concentration. It can be a natural air component, such as carbon dioxide, that rises above its normal concentration, or something not usually found in the air, such as a lead compound. A secondary air pollutant is a harmful chemical formed in the atmosphere through a chemical reaction among air components.We normally associate air pollution with smokestacks and cars, but volcanoes, forest fires, dust storms, marshes, oceans, and plants also add to the air chemicals we consider pollutants. Since these natural inputs are usually widely dispersed throughout the world, they normally don‟t build up to harmful levels. And when they do, as in the case of volcanic eruptions, they are usually taken care of by natural weather and chemical cycles2.As more people live closer together, and as they use machines to produce leisure, they find that their leisure, and even their working hours, become spoilt by a byproduct of their machines – namely, noise,The technical difficulties to control noise often arise from the subjective-objective nature of the problem. You can define the excessive speed of a motor-car in terms of a pointer reading on a speedometer. But can you define excessive noise in the same way? You find that with any existing simple “noise-meter”, vehicles whichare judged to be equally noisy may show considerable differenceon the meter.Though the ideal cure for noise is to stop it at its source, thismay in many cases be impossible. The next remedy is to absorb iton its way to the ear. It is true that the overwhelming majority ofnoise problems are best resolved by effecting a reduction in thesound pressure level at the receiver. Soft taped music in restaurantstends to mask the clatter of crockery and the conversation at thenext table. Fan noise has been used in telephone booths to mask speech interference from adjacent booths. Usually, the problem is how to reduce the sound pressure level, either at source or on the transmission path.6 ANALYTICAL INSTRUMENT MARKETThe market for analytical instruments is showing a strength only dreamed about as little as five years ago. Driven by the need for greater chemical analysis coming from quality control and government regulation, a robust export market, andnew and increasingly sophisticated techniques, sales are increasingrapidly1.The analytical instrument business' worldwides sales arenearly double their value of five years ago, reaching $ 4.1 billion in1987. Such growth is in stark contrast to the doldrums of severalyears ago when economic recession held back sales growth to littleor nothing. In recent years, the instrumentation market hasrecovered, growing at nearly 9% per year, and it‟s expected t o continue at this rate at least until the 1990. With sales increases exceeding inflation, the industry has seen the real growth demonstrating the important role of chemical instrumentation in areas such as research and development, manufacturing, defense, and the environment in a technologically advancingworld2.Chromatography is the fastest-growing area, comprising 40%, or $ 1.5billion, in 1987 world sales. Chromatographic methods are used extensively inindustrial labs, which purchase about 70% of the devices made, for separation,purification, and analysis. One of the biggest words in all forms of chromatography is “biocompatibility.” Biocompatible instruments are designed to have chemically inert, corrosion-resistant surfaces in contact with the biological samples.Gas Chromatography sales are growing at about the same rate as the instrument market. Some of the newest innovations in GC technology are the production of more instruments with high-efficiency, high-resolution capillaries and supercritical fluid capability.Despite having only a 3% share of the GC market, supercritical fluid chromatography (SFC) has attracted a great deal of attention since its introduction around 1985 and production of the first commercial instrument around 1986. SFC, which operates using asupercritical fluid as the mobile phase, bridgesthe gap between GC and HPLC. The useof these mobile phases allows for higherdiffusion rates and lower viscosities thanliquids, and a greater solvating powerthan gases.Another area showing tremendous growth is ion chromatography (IC). From growth levels of 30% per year in the U.S. and similar levels worldwide, the rate is expected to drop slightly but remain high at 25%. The popularity of IC has been enhanced through extending its applicability from inorganic systems to amino acids and other biological systems by the introduction of biocompatible instruments.Mass spectrometry (MS) sales have been growing about 12% annually. Sales have always been high, especially since MS is the principal detector in a number of hyphenated techniques such as GC-MS, MS-MS, LC-MS, and GC-MS accounts for about 60% of MS sales since it is used widely in drug and environmental testing. Innovations in interface technology such as inductively coupled plasma/MS, SFC/MS, and thermospray or particle beam interfaces for LC-MS have both advanced the technology and expanded the interest in applications. Recent MS instruments with automated sampling and computerized data analysis have added to the attractiveness of the technique for first time users.Spectroscopy accounts for half of all instrument sales and is the largestoverall category of instruments, as the Alpert & Suftcliffe study shows. It can be broken down evenly into optical methods and electromagnetic, or nonoptical, spectroscopies. These categories include many individual high-cost items such as MS, nuclear magnetic resonance spectrometers, X-ray equipment, and electron microscopy and spectroscopy setups. Sales of spectroscopic instruments that are growing at or above the market rate include Fourier transform infrared (FTIR), Raman, plasma emission, and energy dispersive X-ray spectrometers. Others have matured and slowed down in growth, but may still hold a large share of the market.The future of analytical instrumentation does not appear to be without its new stars as there continue to be innovations and developments in existing technology. Among these are the introduction of FT Raman, IR dichroism, IR microscopy, and NMR imaging spectrometers. Hyphenated and automated apparatus are also appearing on the market more frequently. New analytical techniques like capillary electrophoresis, gel capillary electrophoresis, scanning tunneling microscopy for the imaging of conducting systems, atomic force microscopy for the imaging of biological systems, and other techniques for surface and materials analysis are already, or may soon be, appearing as commercialized instruments. And, if the chemical industry continues to do well in the next few years, so too will the sales of analytical instrumentation.The effect of alcohol have both medical and medicolegal implications. The estimationof alcohol in the blood or urine is relevant when the physician needs toknow whether it is responsible for the condition of the patient. From themedicolegal standpoint the alcohol level is relevant in cases of suddendeath, accidents while driving, and in cases when drunkenness is thedefense plea. The various factors in determining the time after ingestion showing maximum concentration and the quality of the alcohol are the weight of the subject, the amount and concentration of the alcohol, how the alcohol was ingested, the presence or absence of food, and the physical state of the subject concerned1.7 DETERMINATION OF BLOOD ALCOHOL WITH GAS CHROMATOGRAPHYThe effects of alcohol vary among individuals and for the same individuals at different times. The action depends mostly on the environment and thetemperament of the individual and on the degree of dilution of the alcoholconsumed. The habitual drinker usually shows relatively less effect than wouldbe seen with an occasional drinker from the same amount of alcohol. Drugspotentiate the effect of alcohol.Many cases document the synergistic effect of alcohol and barbiturates as a cause of death in cases appearing to be suicide. Alcohol itself is probably the most frequent cause of death due to poisoning.A gas-solid chromatographic technique using flame ionization detection and a Porapak Q column has been used for the identification and determination of ethanol, isopropanol, and acetone in pharmaceutical preparations. The technique involves direct injection of an aqueous dilution of the product and thus is simple and direct.Sample Preparation. Two 0.5-ml volumes of an isobutanol internal standard (10 mg/ml water; pipette 12.4 ml of isobutanol and dilute to 1 liter with water) are pipetted into two different 2-dram (7.4-ml) shell vials, one market “known.” and the other “unknown.” A 0.5-ml portion of the ethanol working standard (50 mg/100ml of blood; pipette 5ml of ethanol stock solution; dilute 12.7 ml of absolute ethanol to 1 liter with water, and dilute with 100 m l of blood from blood bank) is transferred to the vial marked “known.” The。

中华人民共和国电力法英文版The Electricity Law of the People's Republic of China is a key piece of legislation that has been enacted to govern the country's electricity sector. This law provides a legal framework within which China's electricity industry operates, and it plays a central role in shaping the industry's development.The law was first enacted in 1995 and has since been amended several times to keep pace with the evolving needs of China's electricity sector. The latest version of the law was passed in December 2020 and includes major revisions that reflect China's commitment to a low-carbon energy future.One of the key features of the Electricity Law is its emphasis on the development of renewable energy sources such as wind, solar, hydroelectric, and nuclear power. The law requires power companies to develop and utilize renewable energy sources to meet a certain percentage of their overall energy needs. This provision has led to a surge in renewable energy development in China and has helped the country become a global leader in renewable energy deployment.Another important aspect of the Electricity Law is its focus on energy conservation and efficiency. The law requires power companies to adopt energy-efficient technologies and practices to reduce their overall energy consumption. This provision hashelped China improve its energy efficiency and reduce its carbon footprint.The Electricity Law also establishes a licensing system for power generation, transmission, and distribution companies. It sets out the conditions for obtaining licenses and outlines the responsibilities of licensed companies. This licensing system has helped ensure that the electricity industry operates in a fair and transparent manner, and has helped to promote competition in the sector.In addition, the Electricity Law includes provisions related to the pricing of electricity and the protection of consumer interests. The law prohibits power companies from engaging inanti-competitive pricing practices or monopolistic behavior, and it ensures that consumers have access to affordable and reliable electricity.Overall, the Electricity Law of the People's Republic of China is a critical piece of legislation that has helped guide the development of China's electricity sector. Its emphasis on renewable energy and energy efficiency has helped China become a leader in the transition to a low-carbon energy future, and its licensing system has helped ensure that the industry operates in a fair and transparent manner. As China continues to transform its energy system, the Electricity Law will continue to play a central role in shaping the direction of the industry.。

44In recent years, Chinese auto companies have frequently expanded their businesses in Southeast Asian markets such as Indonesia, Vietnam, Thailand, and Malaysia, relying on their first-mover advantages in the new energy sector. Many of their vehicle models have become highly popular among local people.Taking Thailand as a baseIn the first quarter of 2023, China’s automobile exports reached 1.069 million units, a year-on-year increase of 58.7%, surpassing Japan’s 1.047 million units during the same period, and temporarily ranking as the world’s largest automobile exporter.The Southeast Asian market represented by Thailand has become a window for Chinese new energy vehicle enterprises to “go global”, due to its large population, great consumption potential and market prospects. Chinese automakers have taken Thailand as a stepping stone to extend their business throughout Southeast Asia. According to the Thai Automotive Institute,Chinese auto brands account for over 90% of the total sales of new energy vehicles in Thailand. For example, since Great Wall Motor entered the Thai market in February 2021, it has become the top energy vehicle brand in Thailand within just two years.Thailand has always held a positive attitude towards the entry of foreign investment into the domestic market, especially in the field of new energy. The Thai government has increased its efforts in the development of new energy and introduced strong policy support, for example, offering 8-year tax exemptions for electric vehicle manufacturers, waiving import tariffs for batteries and electric motors by 2025, and providing subsidies to auto manufacturers for electricity costs.In order to enjoy these preferential policies and subsidies, auto companies need to have factories in Thailand. Due to the low local labor costs and strong tax incentives for factory construction, Chinese auto brands normally choose joint ventures, acquisition and sole proprietorship to build factories in Thailand.In March this year, BYD officially laid the foundation for its production factory in Rayong Province, an important auto production and export base in Thailand. The factory is expected to start production in 2024. In April, Changan Automobile announced that it would invest USD 285 million to build a factory in Thailand to produce its first right-hand drive car outside of China. Also in April, SAIC Motor announced the construction of a new energy auto industrial park in Thailand. In May, a spokesperson of the Thai government said in a statement that Hezhong had signed an agreement with a Thai automotive assembly company to produce the Nezha V model locally next year.According to public market information, Chinese new energy auto companies have invested more than RMB 20 billion in Thailand. Particularly this year, Thailand has become the favorite of Chinese auto companies.The overall potential of the Southeast Asian market is also huge. According to the International Energy Agency’s Global EV Outlook 2023, the sales volume of electric vehicles in Indonesia increased by 200% in 2022, while sales in Thailand doubled. According to the well-known research firm Counterpoint, the Southeast Asian electric vehicle market will grow rapidly, and by 2029, more than 3.5 million electric vehicles will be sold, with a compound annual growth rate of 124%.Low priceChinese electric vehicle brands have clear advantages in Southeast Asia, mainly due to their low prices. Compared with electric vehicle brands in other countries, Chinese electric vehicles are more affordable, meeting the needs and budgets of local consumers.For example, in the Indonesian market, the selling price of the Chinese brand Wuling Hongguang MINI EV is only around U SD 10,000, which is much cheaper than foreign brands such as Tesla. In addition, the performance and quality of Chinese electric vehicles have gradually gained consumer recognition and trust. By comparison, some foreign brand electric vehicles are still unable to match local consumption needs due to their high prices.By Lily WangChina’s Electric Vehicles Are Popular in Southeast Asia45“Since Wuling Air EV entered Indone sia i n Aug ust 2022, t he cumulative sales volume has exceeded 8,600 units,” a representative of SAIC-GM-Wuling said recently.Coincidentally, brands such as SAIC, Great Wall, and BYD have also started operations in Southeast Asia. SAIC Zhengda New Energy Industrial Park held a groundbreaking ceremony in Thailand in April this year, and Great Wall Motor launched three new energy vehicle models in the Malaysian market in May.Driven by policy, the popularity of electric vehicles in Indonesia is gradually increasing. A representative from SGMW Wuling said: “our independent production base in Indonesia has been operating for many years. In 2022, the Indonesian branch sold a total of 30,037 vehicles. Wuling Air EV has accounted for 80% of the local new energy vehicle market.”It is also worth mentioning that the initial selling price of the Wuling Air EV exceeds 200 million Indonesian rupees, which counts as a luxury item in the local area and requires the payment of a luxury sales tax. “However, its pricing is in line with the design concept and rich technological configuration of the product itself,” explained the representative.“Having the fourth largest population in the world, Indonesia is the largest economy in Southeast Asia, and has strong economic vitality, a broad market and a large user demand. In addition, Indonesia has a relatively low number of vehicles, and the auto industry is one of the five priority manufacturing industries promoted by the Indonesian government. As such, the auto industry has policy support. We expect Indonesia will be a base for SGMW Wuling to export to the rest of the Southeast Asian market,” said the representative of SGMW Wuling.In addition to Indonesia, Chinese electric vehicle companies are also making continuous efforts in the markets of Singapore, Malaysia, and Vietnam.Li Yunfei, General Manager of the Brand and Public Relations Department of BYD Group, revealed on social media that in April, BYD ATTO 3 became the best-selling electric vehiclein Singapore. He also revealed that the Singaporean government uses high COE (certificate of entitlement) fees to control the increase of new cars. After paying taxes and COE fees, the minimum price of ATTO 3 is nearly RMB 900,000.According to the news released on May 15 on BYD’s official WeChat official account, BYD ATTO 3 is currently the best-selling model in Singapore. The 100 kW version is selling at SGD 183,888 (including COE), equivalent to about RMB 956,000, and the 150 kW version is selling at SGD 202,888 (including COE), equivalent to about RMB 1.054 million.The overall penetration rate of electric vehicles in Southeast Asia is still only less than 2%. However, as Thailand, Indonesia, Vietnam and other countries have successively introduced a number of favorable policies, such as tax relief, car purchase subsidies, the promotion of clean energy for public transport, and the construction of charging stations, this will be very beneficial for Chinese new energy vehicle brands going overseas.Continuous technology advancementsAt present, many domestic and foreign automakers are actively developing electric vehicles and accelerating the development of the new energy vehicle industry.For example, a Chinese auto company is developing a new type of battery that features fast charging, high energy density, and a better safety performance.Intelligent technology has also been widely applied in the field of electric vehicles, such as unmanned driving and intelligent charging, further improving the safety and convenience of electric vehicles.Chinese auto companies have also worked with local institutions to build R&D centers to improve their brand reputation. For example, in 2014, the Singapore Agency for Science, Technology and Research announced the signing of a joint laborator y agreement with BYD to jointly develop electric vehicle systems for Singapore’s public transportation; in 2016, the Go Ahead Bus Group conducted testingusing electric buses manufactured by BYD; and in 2017, the first batch of taxis using BYD models started running on the roads of Singapore.However, Chinese auto companies have also faced tremendous challenges in their business development in Southeast Asia. Taking the Indonesian market as an example, although SGMW Wuling’s manufacturing base has been operating for years, its competitors have also started to find their way into the market.In Indonesia, the IONIQ 5 electric SUV model produced locally by Korean automaker Hyundai has become a strong competitor to the Wuling Air EV . Hyundai also plans to launch more pure electric vehicles in Indonesia to occupy the growing market. Faced with the fierce competition in the overseas markets, the pressure on Chinese auto companies is evident.T an Xiaoyan, senior visiting researcher at the Yusof Ishak Institute, pointed out that although Japanese, Korean, European and American brands have occupied the fuel vehicle market in Southeast Asia, they have not yet penetrated the electric vehicle market. These enterprises have already paid huge sinking costs on fuel vehicle production facilities, so they tend to continue to use existing facilities to produce fuel vehicles. This provides opportunities for new-coming auto companies from China and other countries to enter the Southeast Asian market and build local factories. These new companies do not have to wait for the phasing out of old fuel vehicle factories.At present, many domestic and foreign automakers are actively developing electric vehicles and accelerating the development of the new energy vehicle industry.。

中国新能源汽车高速发展的原因英文作文全文共5篇示例，供读者参考篇1The Fast Growth of New Energy Cars in ChinaHi friends! Today I want to talk to you about the really cool new energy cars that are becoming so popular in my country, China. These are cars that run on electricity or other clean fuels instead of gasoline. I think they are super neat and I'll tell you why China has been building so many of them lately.First, let me explain what a new energy vehicle is. The main types are fully electric cars that get their power from big rechargeable batteries, and plug-in hybrid cars that can run on both electricity and gasoline. There are also cars that run on hydrogen fuel cells or other clean fuels. The key thing is that they don't burn gasoline or diesel like regular cars, so they don't make bad pollution that dirties up the air we breathe.China has been working really hard to make more and more of these new energy cars. In fact, we now make and sell more of them than any other country! Just a few years ago in 2020, around 1.3 million new energy cars were sold in China. But thatnumber grew super quickly, and by 2022 it was over 6.5 million! That's about half of all the electric cars sold globally. Wow!So why is China going so full speed ahead with these modern, eco-friendly cars? There are a few main reasons:Cleaning Up Air PollutionOne of the biggest reasons is to help make the air cleaner and healthier to breathe, especially in big cities. When I was younger, I remember lots of days when the sky looked really hazy and gross because of smog from car exhaust, factories, and coal power plants. It was awful and it made my parents really worried about me playing outside.But over the last decade, China has made huge efforts to shut down dirty factories and power plants, and get people to start driving zero-emission electric cars instead of gasoline burners. The air quality has improved a ton where I live, and I bet it's even better in cities that are pushing new energy cars the hardest. My parents say I'm really lucky to be growing up with much cleaner air than they had as kids.Saving on Oil ImportsAnother big reason is that China doesn't have very many oil fields or gasoline/diesel resources of its own. We have to importhuge amounts of expensive oil from other countries to meet our fuel needs. But electricity can be made right here at home from cleaner sources like solar, wind, nuclear and hydropower plants.By driving on domestically-produced electricity instead of imported oil, China can save billions on energy costs and become more self-sufficient. It also means we won't be so dependent on foreign countries for our transportation fuel. That's a way better situation for China's economy and energy security.Taking the Lead in New TechnologiesChina's government and companies are also working hard on new energy vehicles because they want to become world leaders in this cutting-edge technology and industry. Whoever gets really good at making the best and most affordable electric car batteries, motors, and smart software systems will have a huge advantage in the future auto market globally.Right now, Chinese companies like BYD, Nio, Xpeng and others are doing an amazing job of innovating and bringing down costs for electric cars. They are helping push China to the forefront of this super important new technology that could be worth trillions of dollars in sales in the coming years as gasoline cars get phased out.Supporting Domestic IndustriesFinally, boosting new energy vehicle production helps support lots of different industries in China like battery makers, mining companies for lithium and other materials, electricity providers, and even high-tech software developers. The government really wants to see these modern, high value-added businesses grow and create millions of good jobs across the country.Pretty much every part of an electric car has to be made in China now, unlike decades ago when we just assembled foreign gasoline models. This is creating a whole new Industrial supply chain that makes China richer and stronger versus just importing old oil-burning technologies. It's a way to move our economy into the future.So in summary, those are the big reasons why China has become the number one country for manufacturing the cleanest, most advanced cars that don't need gasoline. It's helping us breathe fresher air, saving tons of money, creating good new jobs, and putting China at the forefront of next-generation auto tech. Maybe your family will be driving an affordable Chinese electric car sooner than you think!I hope you found this little essay interesting and helpful for understanding why electric cars have taken off so rapidly here.

My name is Xiaoming and I'm here to tell you all about the really cool new energy cars that are becoming so popular in my home country of China. These are cars that run on electricity or other fuels besides gasoline and diesel. Instead of spewing out smelly, dirty exhaust like regular cars, new energy cars are much cleaner and better for the environment. Pretty neat, right?China has been working really hard to make more and more of these new energy vehicles. In fact, we now make and sell way more of them than any other country! There are lots of reasons why China's new energy car industry has taken off so fast. Let me break it down for you:First of all, pollution has become a huge problem in many of China's big cities like Beijing. With so many cars on the road belching out emissions, the air quality can get really bad sometimes. It makes it hard to breathe and can cause health issues. My parents are always complaining about the smog! New energy cars help reduce this pollution problem since they don't directly create any exhaust.The Chinese government has also been strongly encouraging people to start driving these cleaner cars through different policies and incentives. For example, they give people tax rebates if they buy a new energy vehicle. In some cities, if you have an electric car, you can even drive in the carpool lane without any passengers! How cool is that?There are also limits on how many new regular gas-powered cars can be registered in crowded cities each year. But those limits don't apply to new energy vehicles. So if you want to get anew car in a place like Beijing, your best option is often an electric one since there's no restrictionon registrations.Along with encouraging consumers, China's leaders are also pushing auto companies really hard to manufacture more new energy models and make them more affordable for regular people. The government has set targets that carmakers need to meet for producing a certain percentage of new energy vehicles each year or else they have to pay penalties. Yikes!With so much pressure and so many incentives, it's no wonder that Chinese car companies have really doubled down on electric and hybrid vehicles in recent years. Brands like BYD, Nio, Xpeng and Li Auto are making some seriously cool new energy models that are becoming super popular among Chinese car buyers.China also has an abundance of companies that manufacture parts like batteries and electric motors for new energy cars.

Today, I'm going to tell you all about the amazing new energy cars in China and why they're becoming so popular. Get ready to learn some cool stuff!First, let's talk about what new energy cars are. They're vehicles that run on electricity or other eco-friendly fuels instead of gasoline or diesel. Some examples are electric cars, hybrid cars, and fuel cell cars. These cars are awesome because they don't pollute the air as much as regular cars, which is great for the environment.Now, you might be wondering why China is leading the way in new energy cars. Well, there are a few important reasons:China wants to be a world leader in new technologies.China is a really big and important country, and its leaders want it to be the best at everything, including new and exciting technologies like new energy cars. They know that these cars are the future, so they're working hard to make China the number one place for developing and building them.China has a lot of people and cities.China has a huge population, which means a lot of people need cars to get around. But with so many people living in big cities, pollution from regular cars can become a big problem. New energy cars help reduce this pollution, making the air cleaner and healthier for everyone.China wants to save money on oil and gas.Regular cars need gasoline or diesel to run, which has to be imported from other countries. This costs a lot of money! New energy cars, on the other hand, run on electricity or other fuels that can be produced in China itself. This saves the country a ton of money in the long run.The Chinese government supports new energy cars.The leaders in China have made it a priority to encourage people to buy and use new energy cars. They do this by givingout incentives, like tax breaks and subsidies, to people who choose these eco-friendly vehicles. This makes new energy cars more affordable and attractive to buyers.Chinese companies are innovating like crazy!Chinese companies like BYD, Nio, and Xpeng are working hard to design and build the coolest new energy cars ever. They're coming up with awesome features like super long battery ranges, self-driving capabilities, and sleek, futuristic designs. These companies are pushing the boundaries of what's possible in new energy cars.So, as you can see, there are lots of great reasons why new energy cars are becoming so popular in China. The country's leaders want to be technology leaders, reduce pollution, save money on oil and gas, and encourage people to go green. Plus, Chinese companies are making some of the most advanced new energy cars in the world!I think it's really exciting to see China leading the way in this important technology. Who knows, maybe one day we'll all be driving around in cool Chinese-made new energy cars! For now, I'm just glad these cars are helping to make the air cleaner and our planet healthier.What do you think about new energy cars? Let me know if you have any other questions!篇5The Awesome Rise of Electric Cars in ChinaElectric cars are becoming super popular in China! My dad just got a brand new Tesla and it's so cool. It doesn't make any noise or smoke when driving. When I was younger, all the cars on the road used gasoline and made a lot of stinky fumes. Now there are more and more electric vehicles (EVs) zooming around my city. Let me tell you why China has seen such an awesome rise in these high-tech EVs!The first big reason is that the Chinese government gives a lot of support to electric car companies. They provide tons of money to help companies like BYD, Nio, Xpeng and others afford to design and build quality EVs. The leaders in Beijing want China to become a world leader in this new technology. By assisting EV manufacturers, they hope to create many good jobs in this growing industry.The government also gives people discounts and other benefits if they purchase an electric car instead of a normalgas-powered one. My uncle saved over 5,000 when he boughthis slick new Xpeng sedan thanks to these EV incentives. The government hopes more people will choose EVs, which helps reduce pollution from vehicle emissions. It's a really smart policy.Another key factor is that the cost of EVs in China has dropped dramatically in recent years due to technological improvements and economies of scale. The batteries which power electric cars used to be super expensive, but companies have found ways to manufacture them much more cheaply without sacrificing performance. EV sticker prices are now very comparable to similar gas models.Cheaper EVs combined with government incentives means the overall ownership costs of an electric car in China can actually be lower than a conventional car after just a few years. EV drivers also save a ton on fuel costs since electricity is way cheaper than gasoline. More affordable pricing has allowed the mass market adoption we are witnessing today.Consumer attitudes have also changed dramatically. Just a few years ago, EVs were seen by many in China as odd novelties with limited ranges and long charging times that were impractical for daily use. But the latest EV models can now travel over 600 km on a single charge and only take about 30 minutesto recharge at a fast charging station. These are perfectly normal and usable cars for the average family.Chinese automakers have also worked hard to design EVs that are sleek, high-tech and desirable products that people get excited about. The interiors look straight out of a futuristic movie with huge touchscreens and fancy self-driving features. Parents love getting EVs because their kids think they are so awesome. It's the cool thing to have now.On top of that, China is fully committed to expanding EV charging facilities across the entire country. Charging piles are going up everywhere you look - at offices, apartments, shopping malls, you name it. Drivers don't need to stress about running out of juice anymore. The government has mapped out plans to install millions of public charging stations over the next few years.Lastly, most Chinese people live in big cities where driving ranges tend to be short since everything is close together. EVs are perfect for city driving. There are also a lot of license plate restrictions in Beijing, Shanghai and other major cities that discourage people from buying gas cars. But policies often make it easier to get plates for EVs, another incentive that promotes their adoption.So those are some of the key reasons why electric vehicles are becoming so wildly popular and growing at a blistering pace here in China. Between strong government support, improved technology and pricing, changing social attitudes, major charging infrastructure buildouts, and an urban-based population, the conditions are perfect for mass EV adoption.Pretty soon, it will be weird to see somebody driving an old gas guzzler! The electric car revolution is already happening at highway speeds in cities across this vast country. I can't wait until I'm old enough to get my own Tesla or Nio and cruise the streets without making any carbon footprints. EVs are so awesome for the environment and just way cooler than grandpa's smelly, noisy clunker. That's the future!。
