The reserve buoyancy which is measured by freeboard refers to the watertight volume of hull above load line.2）、我们不必为空气的阻力多伤脑筋，因为与水阻力相比空气阻力要小得多。

We do not bother our brain about air resistance because it is far smaller than water resistance.二、英译汉1、Then, what is the reserve buoyancy? As it is known to all, a ship has to obtain a certain amount of freeboard when she’s sailing at sea. That is to say, to give you a concrete idea, any vessel is to retain some volume above water for the sake of extra buoyancy so that its draft is allowed to increase without a sinking tragedy under particular but rare conditions, such as rough sea or serious flooding due to hull damage.那么什么是储备浮力呢？大家明白，当船只在海上航行时它必须获得一定量的干舷。

When I got to Crow Creek， Magpie was not home. I talked to his wife Amelia. “我要找喜鹊，”我说，“我给他带来了好消息。

”我指指提着的箱⼦，“我带来了他的诗歌和⼀封加利福尼亚⼤学的录取通知书，他们想让他来参加为印第安⼈举办的艺术课。

” “I need to find Magpie，” I said. “I've really got some good news for him.” I pointed to the briefcase I was carrying. “I have his poems and a letter of acceptance from a University in California where they want him to come and participate in the Fine Arts Program they have started for Indians.” “你知道他还在假释期间吗？” “Do you know that he was on parole？” “这个，不，不⼤清楚。

”我犹豫着说，“我⼀直没有和他联系，但我听说他遇到了些⿇烦。

” “Well， no， not exactly，” I said hesitantly， “I haven't kept in touch with him but I heard that he was in some kind of trouble. 她对我笑笑说：“他已经离开很久了。

你知道，他在这⼉不安全。

他的假释官随时都在监视他，所以他还是不到这⼉来为好，⽽且我们已经分开⼀段时间了，我听说他在城⾥的什么地⽅。

Reading Material 6Stainless SteelStainless steels do not rust in the atmosphere as most other steels do. The term "stainless" implies a resistance to staining, rusting, and pitting in the air, moist and polluted as it is, and generally defines a chromium content in excess of 11 % but less than 30%. And the fact that the stuff is "steel" means that the base is iron.Stainless steels have room-temperature yield strengths that range from 205 MPa (30 ksi) to more than 1725 MPa (250 ksi). Operating temperatures around 750 C (1400 F) are reached. At the other extreme of temperature some stainless steels maintain their toughness down to temperatures approaching absolute zero.With specific restrictions in certain types, the stainless steels can be shaped and fabricated in conventional ways. They can be produced and used in the as-cast condition; shapes can be produced by powder-metallurgy techniques; cast ingots can be rolled or forged (and this accounts for the greatest tonnage by far). The rolled product can be drawn, bent, extruded, or spun. Stainless steel can be further shaped by machining, and it can be joined by soldering, brazing, and welding. It can be used as an integral cladding on plain carbon or low-alloy steels.The generic term "stainless steel" covers scores of standard compositions as well as variations bearing company trade names and special alloys made for particular applications. Stainless steels vary in their composition from a fairly simple alloy of, essentially, iron with 11% chromium, to complex alloys that include 30% chromium, substantial quantities of nickel, and half a dozen other effective elements. At the high-chromium, high-nickel end of the range they merge into other groups of heat-resisting alloys, and one has to be arbitrary about a cutoff point. If the alloy content is so high that the iron content is about half, however, the alloy falls outside the stainless family. Even with these imposed restrictions on composition, the range is great, and naturally, the properties that affect fabrication and use vary enormously. It is obviously not enough to specify simply a "stainless steel.”Classification the various specifying bodies categorize stainless steels according to chemical composition and other properties. However, all the stainless steels, whatever specifications they conform to, can be conveniently classified into six major classes that represent three distinct types of alloy constitution, or structure. These classes are ferritic, martensitic, austenitic, manganese-substituted austenitic, duplex austenitic ferritic, and precipitation-hardening. Each class is briefly described below.(1) Ferrous stainless steels: This class is so named because the crystal structure of the steel is the same as that of iron at room temperature. The alloys in the class are magnetic at room temperature and up to their Curie temperature (about 750 C; 1400 F). Common alloys in the ferrous class contain between 11% and 29% chromium, no nickel, and very little carbon in the wrought condition.(2)Martensitic stainless steels: Stainless steels of this class, whichnecessarily contain more than 11 % chromium, have such a great hardenability that substantial thickness will harden during air cooling, and nothing more drastic than oil quenching is ever required. The hardness of the as-quenched martensitic stainless steel depends on its carbon content. However, the development of mechanical properties through quenching and tempering is inevitably associated with increased susceptibility to corrosion.(3)Austenitic stainless steels: The traditional and familiar austeniticstainless steels have a composition that contains sufficient chromium to offer corrosion resistance, together with nickel to ensure austenite at room temperature and below. The basic austenitic composition is the familiar l8% chromium, 8% nickel alloy. Both chromium and nickel contents can be increased to improve corrosion resistance, and additional elements (most commonly molybdenum) can be added to further enhance corrosion resistance.(4)Manganese-substituted austenitic stainless steels: The austeniticstructure can be encouraged by elements other than nickel, and the substitution of manganese and nitrogen produces a c1ass that we believe is sufficiently different in its properties to be separated from the chromium-nickel austenitic class just described. The most important difference lies in the higher strength of the manganese-substituted alloys.(5) Duplex austenitic-ferrous stainless steels: The structure of these steels isa hybrid of the structures of ferrite and austenite; and the mechanical properties likewise combine qualities of each component steel type. The duplex steels combine desirable corrosion and mechanical properties, and their use is as a result increasing in both wrought and cast form.(6) Precipitation-hardening stainless steels: Stainless steels can be designed so that their composition is amenable to precipitation hardening. This class cuts across two of the other c1asses, to give us martensitic and austenitic precipitation-hardening stainless steels. In this class we find stainless steels with the greatest useful strength as well as the highest useful operating temperature.Properties In selection of stainless steels, three kinds of properties have to be considered: (1) Physical properties: density, thermal conductivity, electrical resistivity, and so on; (2) Mechanical properties: strength, ductility, hardness, creep resistance, fatigue, and so on; and (3) corrosion-resistant properties. Note that properties of stainless steels are substantially influenced by chemica1 composition and microstructure. Hence specifications include chemical composition, or, more correctly, an analysis of the most important elements (traces of unreported elements also may be present) as well as a heat treatment that provides the optimum structure.Applications Since stainless steels were first used in cutlery industry, the number of applications has increased dramatically. The relative importance of the major fields of application for flat and long stainless steel products is shown in Table 1. Chemical and power engineering is the largest market for both long and flat products. It began in about 1920 with the nitric acid industry. Today, it includesan extremely diversified range of service conditions, including nuclear reactor vessels, heat exchangers, oil industry tubular, components for the chemical processing and pulp and paper industries, furnace parts, and boilers used in fossil fuel electric power plants.Table 1阅读材料 6不锈钢不锈钢就像其他大多数的钢在空气中不会生锈，“不锈的”这个术语暗示了在空气中抵抗污点，生锈和腐蚀，还具有抵抗潮湿和腐蚀。

FREEWAY TRAFFIC FLOW MODELING BASED ON RECURRENT NEURAL NETWORK AND WAVELET TRANSFORM基于递归神经网络和小波变换的高速公路交通流建模6 Conclusions 结论The highly nonlinear and dynamic characteristics of the macroscopic traffic flow require a modeling approach, which can deal with the complex nonlinear relationships among the speed, flow and density.宏观交通流的高度非线性和动态特性，需要一个建模方法，它可以处理的速度，流量和密度之间的复杂的非线性关系。

At the same time, effective measures have to be taken to eliminate traffic noise and disturbance. In this paper, a method of wavelet denoising and traffic flow modeling by an Elman recurrent neural network is presented.同时，必须采取有效措施来消除交通噪声和干扰。

在本文中，一种小波去噪和交通流的Elman神经网络建模这工作了。

Simulation results show that the wavelet transform can effectively eliminate the noise signal, and that the Elman network can accurately describe the real behavior of freeway traffic flow.仿真结果表明，小波变换可以有效地消除信号中的噪声，和Elman神经网络能够准确地描述高速公路交通流的真实行为。

06．THE CLASSIFICATION OF INORGANIC COMPOUNDS The Classes of Compounds该类化合物Thousands and tens of thousands of compounds are known to the chemist today. It would be impossible to learn properties and behavior of even a fraction of this number if it had to be done on the basis of individual compounds1. Fortunately, most chemical compounds can be grouped together in a few classes. Then, if we can properly classify a compound .we are at once aware of the general properties of the compound from knowledge of the properties of that class or group of compounds. For example. HCl is classed as an acid. and by becoming familiar with the behavior of acids as a distinct class, we are at once aware of the general properties of the compound2. A great many of the compounds we are to study may be classified as acids, bases, salts, metallic oxides, or nonmetallic oxides. Of these five classes of compounds, the first three —acids, bases, and salts — are by far the most important3…成千上万的化合物是众所周知的今天的化学家。

Psychology changed dramatically during the early20th-century as another school of thought known as behaviorism rose to do minance.Behaviorism was a major change from previous theoretical perspectives,rejecting the emphasis on both the conscious and unconscious mind.instead,behaviorism strove to make psychology a more scientific discipline by focusing purely on observable behavior.在早期的心理发生了显著的变化20th世纪中叶作为另一个学校的思想被看作是“行为主义上升到的优势。

行为主义是一个重大的改变从先前的理论观点,拒绝强调了有意识和无意识的想法。

相反,行为主义心理学努力使更科学的学科,其产生的可观察行为集中在纯粹。

Behaviorism had its earliest start with the work of a Russian physiologist named Ivan Pavlov.Pavlov research on the digestive systems of dogs led to his discovery of the classical conditioning process,which demonstrated that behaviors could be learned via conditioned associations Pavlov demonstrated that this learning process could be used to make an association between environmental stimulus and a naturally occurring stimulus.行为主义有其最早开始的工作一个俄罗斯生理学家名叫伊凡巴甫洛夫。
