中南大学版固体物理学习题及答案详解分析

第一章晶体结构1.试述晶态、非晶态、准晶、多晶和单晶的特征性质。
解:晶态固体材料中的原子有规律的周期性排列,或称为长程有序。
非晶态固体材料中的原子不是长程有序地排列,但在几个原子的范围内保持着有序性,或称为短程有序。
准晶态是介于晶态和非晶态之间的固体材料,其特点是原子有序排列,但不具有平移周期性。
另外,晶体又分为单晶体和多晶体:整块晶体内原子排列的规律完全一致的晶体称为单晶体;而多晶体则是由许多取向不同的单晶体颗粒无规则堆积而成的。
2.晶格点阵与实际晶体有何区别和联系?解:晶体点阵是一种数学抽象,其中的格点代表基元中某个原子的位置或基元质心的位置,也可以是基元中任意一个等价的点。
当晶格点阵中的格点被具体的基元代替后才形成实际的晶体结构。
晶格点阵与实际晶体结构的关系可总结为:晶格点阵+基元=实际晶体结构3.晶体结构可分为Bravais格子和复式格子吗?解:晶体结构可以分为Bravais格子和复式格子,当基元只含一个原子时,每个原子的周围情况完全相同,格点就代表该原子,这种晶体结构就称为简单格子或Bravais格子;当基元包含2个或2个以上的原子时,各基元中相应的原子组成与格点相同的网格,这些格子相互错开一定距离套构在一起,这类晶体结构叫做复式格子。
4.图1.34所示的点阵是布喇菲点阵(格子)吗?为什么?如果是,指明它属于那类布喇菲格子?如果不是,请说明这种复式格子的布喇菲格子属哪类?(a)(b)(c)(d)图1.34(a)“面心+体心”立方;(b)“边心”立方;(c)“边心+体心”立方;(d)面心四方解:(a)“面心+体心”立方不是布喇菲格子。
从“面心+体心”立方体的任一顶角上的格点看,与它最邻近的有12个格点;从面心任一点看来,与它最邻近的也是12个格点;但是从体心那点来看,与它最邻近的有6个格点,所以顶角、面心的格点与体心的格点所处的几何环境不同,即不满足所有格点完全等价的条件,因此不是布喇菲格子,而是复式格子,此复式格子属于简立方布喇菲格子。

Some people say that human beings are the only animals that have language. Is this true? It is a very difficult question to answer. A person must have a good definition of “language”. Different kinds of animals must be studied. Some animals certainly seem to have a communication system. That system may or may not be a language. For example, the bee has ways of telling other bees about food. The dolphin has ways of giving information to other dolphins. The monkey can use a human language system. Does this mean animals have language? The answer to this question depends on how “language” is defined. We may define language as any system for exchanging information. If this definition is used, then bees, dolphins, and monkeys all have a language. But language may be defined in another way. We may define language as a system for exchanging information by making new combinations of symbols. If this definition is used, then bees and dolphins do not have a language, but monkeys may have one. Monkeys are clearly able to combine symbols in a human language that they have been taught. This is not their usual language, however. (15分)(1) What do some animals seem to have according to the passage?

(3分)A.person must have a good definition of “language”.B.Different kinds of animals must be studied.nguage may be defined in two waysD.The dolphin has three kinds of calls to tell other dolphins about food.★标准答案:D(5) What does this passage tell us? (3分)A.Animals have language like that of humans if we have a good definitionB.Monkeys are clever enough to learn human language.C.Human beings are the only animals that have language.D.Whether some animals have their own languages depends on how we define language. ★标准答案:D4. It was not yet eleven o'clock when a boat crossed the river with a single passenger who had obtained his transportation at that unusual hour by promising an extra fare. While the youth stood on the landing-place searching in his pocket for money, the ferry man lifted a lantern, by the aid of which, together with the newly risen moon, he took a very accurate survey of the stranger’s figure. He was a young man of barely 18 years old, evidently the country breed, and now, as it seemed, on his first visit to the town. He was wearing a tough gray coat, which was in good shape, but which had seen many winters before this one. The garments under his coat were well constructed of leather, and fitted tightly to a pair of muscular legs; his stockings of blue yarn must have been the work of a mother or sister, and his head was a three-cornered hat, which in its better days had perhaps sheltered the grayer head of the lad’s father. In his left hand was a walking stick, and his equipment was completed by a leather bag not so abundantly stocked as to inconvenience the strong shoulders on which it hung. Brown, curly hair, well-shaped features, bright, cheerful eyes were nature’s gifts, and worth all that art could have done for his adornment. The youth, whose name was Robin, paid the boatman, and then walked forward into the town with a light step, as if he had not already traveled more than thirty miles that day. As he walked, he surveyed his surroundings as eagerly as if he were entering London or Madrid, instead of the little metropolis of a New England colony. (15分)(1) The story took place in ______. (3分)A. winterB.fallC. summerD.spring(2) The boatman was willing to take the young man across the river because _____.

In the old day, children were familiar with birth and death as part of life. This is perhaps the first generation of American youngsters who have never been close by during the birth of a baby and have never experienced the death of a family member. Nowadays when people grow old, we often send them to nursing homes. When they get sick, we transfer them to a hospital, where children are forbidden to visit terminally ill patients-even when those patients are their parents. This deprives (剥夺)the dying patient of significant family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience.Some of my colleagues and I once interviewed and followed approximately 500 terminally ill patients in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We are most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome.It is important for family members, and doctors and nurses to understand these patients' communications in order to truly understand their needs, fears, and fantasies(幻想). Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their tremendous need to be informed, to be kept up-to-date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to cope with the approach of death and finally to reach a true stage of acceptance prior to death. (15分)(1) The elders of contemporary Americans ___________. (3分)A. were often absent when a family member was born or dyingB. were quite unfamiliar with birth and deathC. usually witnessed the birth or death of a family memberD. had often experienced the fear of death as part of life★标准答案:C(2) Children in America today are denied the chance __________ (3分)A.to learn how to face deathB.to visit dying patientsC.to attend to patientsD.to have access to a hospital★标准答案:B(3) Five hundred critically ill patients were investigated with the main purpose of _________.

(3分)A.his desire for communication with other peopleB.his fear of approaching deathC.his pessimistic attitude towards his conditionD. his reluctance to part with his family★标准答案:A(5) It may be concluded from the passage that __________. (3分)A.dying patients are afraid of being told of the approach of deathB.most doctors and nurses understand what dying patients needC.dying patients should be truthfully informed of their conditionD. most patients are unable to accept death until it is obviously inevitable ★标准答案:C4. There are many forms of energy. Some of these forms are heat energy, light energy, electrical energy and chemical energy. Any form of energy can be changed into another form. Besides, there is a huge quantity of energy in the atoms of chemical elements. This is called atomic energy. Atomic energy has been used and will be widely used in the future.The greatest source of energy is the sun. Each day the sun sends a lot of energy onto the earth in the form of heat rays and light rays. But to use solar energy in large amounts is a great problem.Sunlight is not steady. Clouds and night cut off the source. Therefore people must find ways to store up solar energy. Different kinds of devices have been developed. The solar-energy collector is one of them, and the solar battery is another. In the future solar energy may take the place of some power sources. (15分)(1) What is this passage about?

中南大学c++题库 下列哪个是C++语言的合法的字符常量__________。 A ”\0” B ’054’ C ’\x89’ D ’\092’ 参考答案 C
A“\0”以双引号界定,是字符串,错。 B '054' 界定了3个字符,错。 C '\x89' 是采用16进制的转义字符,正确。 D '\092'看似转义字符,但是,以0开头的是8进制字符,9不合法,所以还是界定了3个字符,\0,9,2,错。 字符常量通常指单引号括起来的内容,双引号的为字符串,A排除。字符常量中可以用转义序列来表示,如'\t'表示退格,及用转义符号"\"后加ASCll码来表示单一字符,注意此处ASCll码用八进制或十六进制表示,故开始无 0,排除B,D,还有八进制中首字以o(欧)开头,不是零,十六进制以x或X开头。
在C语言中,合法的字符常量是( ) A)'\084' B) '\x43' C)'ab' D) "\0" 字符常量是用单引号括起来的一个字符。 有两种表示方法: 一种是用该字符的图形符号,如'b' ,'y','*'。 另外还可以用字符的ASCII码表示,即用反斜符(\)开头,后跟字符的ASCII码,这种方法也称为转义序列表示法,具体方法是:有两种形式: 一种是用字符的八进制ASCII码,表示为:\odd.这里,ddd是八进制值(o可以省略)。 另一种使用字符的十六进制ASCII码值,表示为 \0xhh或0Xhh 这里hh是两位十六进制值。 如:'A' ,'\101' 和 'x41'都表示同一个字符常量。 转义序列表示法还可以用来表示一些特殊字符,用来显示特殊符号或控制输出格式。 在C语言中,以下合法的字符常量是 A. "\n" B. 'ab' B. 'ab' C. '\x43'
D. '\084' E. '\0
选c A 有双引号,是字符串 B 单引号里只能一个字符 D \0表明是8进制,只能出现0--7的数字 E 书写不完整,右半边的单引号没了
定义整型变量x,y,z并赋初始值6的正确语句是__________。 A int x=y=z=6; B int x=6,y=6,z=6; C x=y=z=6; D int x,y,z=6; 参考答案 B
