Chapter 12 of quantum physicsLearning problem12.1 (1) physical particle DE Broglie wavelength and the particle kinetic energy is derived Ek and rest mass m0.(2) proof, lambda; When,12.2 set a static quality for m0, electrically charged particles as q, by voltage electric field acceleration for U, try to export the representation of a general form of relativistic particle DE Broglie wavelength and the relation between the voltage.12.3 to use 0.2 MeVg in electron microscope and ray gamma-ray microscope the same resolution, must answer for the accelerating voltage of electron acceleration?12.4 to calculate the electronic thA, quantum mechanicsThe north's official website and no specialized course teaching materials, widely used Ceng Jin's book a course of quantum mechanics or an introduction to quantum mechanics. There are a few people see the quantum mechanics (Ⅰ), actually don't have to, I was watching the volume Ⅰ, feel very repetitive, many of them are not the contents of the test. Look in front of any one of the two is enough, I've flipped through these two, and found that the content of the journal volume Ⅰthey basically is not short, just describe more streamlined.Problem sets key recommendation bo-chu qian and was careful to p. quantum mechanics and anatomy of the days. Many questions proposition thought of Peking University is derived from the book, even directly on the original (e.g., 04 years tests for the second edition of the book 6.50 question). The book most subjects are more difficult to remove, some level of competition, the rest is best (i.e., closed book can do full of), and do a few times more, best every again feel a higher level of quantum mechanics. Don't only look at the book title, but to write, some topics could be a big amount of calculation, but must adhere to from beginning to end, because they are both very good training calculation strength of materials. From the point of calendar year examination questions of Peking University, in recent years has a tendency to increase the amount of calculation, especially 08 and 09, calculate the force sent is probably done."Problem analysis" in the title are classic, but the number of too little, only do this book may not be enough. And there were a good book: hubei Chen of the quantum mechanics problem sets and solutions, and style of the book "problem analysis" is very different, mostly is the foundation, has less amount of calculation. If enough time, can be placed before the problem analysis for the use of primer. Book with Peking University and other schools of examination questions for many years, very precious. This book is the only drawback is you can't buy, is said to be the internal data of shandong university. I this is a brother to me, he is looking for a mail order to shandong university. Some schools library seems to collect the book.And this book have to mention, is the big problem of physics "Canon" at hkust volume of quantum mechanics, a lot of people love holding the book fierce bite, but I don't recommend to do it. If too much time, can be selectively do, remember that part identical particles subject well. The book features from closed, don't pay attention to quality, many topic topic repeat each other in the book, there are a lot of typing errors. Had the most "problem analysis" also was closed inside, as the large subset.Some people like to watch a lot of classic books, such as Dirac principles of quantum mechanics, including teaching materials on the physics of feynman, actually for one's deceased father grind totally unnecessary. The role of these classics is to develop our mind and improve self-cultivation, and problem solving and computing power is required in one's deceased father grind goes, and went to look at is not late.Quantum mechanics calendar year of test questions can be found at Peking University. Every year a lot of people say that quantum mechanics subject style has changed a lot, that I'm not in favor of. The change of the so-called, is just change the topic, for instance, sometimes small q, sometimes only a big problem. Change is not so difficult, is relatively simple in the 90 s, difficulty is improved in recent years. There are exceptions, for two years in 99 (Ⅱ) and 08, is more difficult than the other years. Even the phenomenon of tests in the past the original question, such as in the subspace L = 1 Lx matrix representation and eigen states and eigenvalue problem, respectively, in 95, in 98, 99 (Ⅱ) and 09 test paper. Quantum mechanics questions no matter how to change love, are still have focus, such as the identical particles state function representation, non steady state (expandable superposition of steady state) as the evolution of the system over time, the perturbation (especially the degenerate perturbation), variational method and so on almost every year, while scattering never test. NJU the brother said 7 years had an scattering, actually the problem is just the potential function contains the spin operator of one dimensional problem, strictly speaking is not classified as scattering of the chapter, despite the "scatter" in the title. Scattering the chapter still cannot treat STH lightly, in order to insurance, still want to read a book, to solve the problem. Just other chapters in this don't need to spend so much time.Quantum mechanics formula and conclusion is commonly used in a lot of, some still very long, but you'd better try to thoughts to remember, remember that the more the better, and to bear in mind, this can save a lot of time when the exam. Such as this year's the topic of eigen state that strives for the Lx, I will remember the answer, again a bit more steps, the have to ask. Commonly used integral formula to also want to remember, don't waste time again on the test to count them. Some grind friend Posting that quantum mechanics need a lot of math. Actually for one's deceased father grind, high count and the line to the generation of absolute enough knowledge and there is no need to specifically to learn several points, high generation, functional, differential equations, etc. Mathematical methods don't specifically to review, see the appendix after once volumes Ⅰenough. Special functions and complex solutions of ordinary differential equations is not examination, generally involves very little, as long as the book can be read. Second interview might be asked about the mathematical method of problem, first try after the preparation is not late again. Other to add on the mathematics knowledge in physics teaching material, need not specially to learn.Also said that it's just the matter of the system of units. In quantum mechanics are generally used to gaussian, a lot of formula and different with international units. Some questions require specific numerical calculated results, and some constants (such as electronic electricity, etc.) in the international and gauss numerical is different in two kinds of system of units. So the gaussian working unit system to grasp.Second, the classical physicsClassical physics is the direction of theoretical physics of Peking University study subject,consists of two doors, electric and thermal system. Review the use of teaching materials are generally Guo Shuohong electrodynamics and Wang Zhicheng thermodynamics, statistical physics. Professional class exam system in electric or hot school is not much, so this two problem sets book also very few. Review is the focal point can do the homework problems on teaching material (has a matching answer book), these subjects are all very good, recommended to do more a few times. Many classic subject in thermal system of problem sets, this year also take an examination of the above together with the original (wang third version 9.20). Only do these subjects, of course, is not enough. Electric also recommended Lin Xuan Britain and she xiang "electrodynamics antithesis", there are lots of good questions in this book, especially the static static magnetic field, electromagnetic wave propagation, charged particles and electromagnetic wave these chapters. Some topics may be large amount of calculation, but everyone try to calculate the best, there is no time to also want to take a closer look at steps. Thermal system is not a really good exercise book, the big question of physics "Canon" thermal system most of the questions are too simple, heavy topic phenomenon is very serious, and check the direction of Peking University is different also. But in addition to textbook exercises basically can only find this, you have the time, I'd choose to do something for the rest of the browsing. Big problem of physics "Canon" electric coil don't have to do it, the title of the book is more unusual, has a chapter devoted to circuit, triode, operational amplifier are moved in, can finish the book to the cross electrical engineering.Classical physics of Peking University has not publicly past exam and also can't find online, so you don't bother to look for. Classical physics questions generally is said to be fixed, is 15 or so little q plus four big problem, one big problem is to tip the electric and thermal system. Memories from NJU the senior 07 questions and this year's examination questions can see roughly test key of pku. Electric big problem basically take an examination of the electromagnetic wave and the theory of relativity, electrostatic part generally in small q tests. Large heat system main test statistics (especially ensemble theory), part of thermodynamics in general, in the small q tests. Small q every five points, has accounted for half of the sum total, so don't belittle this part. Some small ask very partial, but most of them are from the textbook. To classical physics, so you want to attach textbooks, the concept of common, formula, the conclusion must be very well. Textbooks all depends on each page, including many schools don't speak in class sections, such as thermal system of non-equilibrium statistical and electric charged particles and chapter two, the influence of electromagnetic field names to add the section also want to see the asterisk. These could be got, such as continuous want to change this year is to take an examination of the landau theory and boltzmann equation of relaxation time approximation. Big problem in many shadow can also be found in textbooks. Is understandable, the importance of the textbook exercises books under the condition of lack, less subject source of proposition, had to find in books. Remember when I review, electric and thermal system teaching materials on every page formula and conclusions are listed in the large and small notebook, and then close the book looks at these formulas conclusion push myself, really can't think of it is to hit the books to see, and then make a mark, after must pay attention to when reading a book. Push a few times to do so, textbook content from the beginning to the end of all this, to understand more deeply. Process clear, natural formula are also remember, feel almost all textbooks were finally back down, and the test is met little asked, as long as it is some books, can be easily answered, big question also has the sense of deja vu.This year's classical physics exam is difficult, a lot of people are feeling down after didn't test good, the final score is generally not high (relative to the quantum mechanics). You want to have areview this course.Third, the politicalPersonally, don't need to go to the remedial class review politics, it's only a waste of time. I was called the a * * summer training classes, in addition to by some teachers after a lot of touching on moral encouragement, basically have no knowledge on the harvest. But to see the people around are submitted to the class, you don't always feel psychological imbalance, especially beginners. If you want to report remedial class, as far as possible before the classes will books read it again, listening to lectures can accomplish know fairly well.I recommend test center of the teaching materials and exercises the outline parsing (red) + Wang Suoming the core test case + Chen Xiankui "2000". Near when the exam see "20 days 20 questions" and "the sequence of four", these two special YaTi (especially the part of the current political affairs). Everybody don't depreciate YaTi, some institutions specialized research on this, the experience is very rich, is worth believe, as long as you don't put all your eggs in one basket to the hope that the one this YaTi volume is ok.Many people review the political is not willing to back more. My view is that the back is much not necessarily can get good grades, but less back words will be very dangerous. And to remember things accurately, some seemingly synonyms cannot confuse, such as the development of the productive forces is a "fundamental task of socialism, rather than choose" fundamental purpose ". Political review the sooner the better, especially at ordinary times less contact with the students in science and engineering, preferably in early August before the exam outline out look, earlier so that we can grasp the initiative, the book and problem sets up a few times.rough U1 and U2 = = 100 v 100 v voltage to accelerate after the DE Broglie wavelength lambda 1 and lambda. 2: how much is respectively?12.5 interferometer are used to determine the position of a macroscopic object accuracy of plus or minus 10 to 12 m.
