4. emic: a term in contrast with etic which originates from American linguist Pike’s distinction of phonetics and phonemics. An emic set of speech acts and events must be one that is validated as meaningful via final resource to the native members of a speech community rather than via appeal to the investigator’s ingenuity or intuition alone.

169. transfer: the influence of mother tongue upon the second language. When structures of the two languages are similar, we can get positive transfer of facilitation; when the two languages are different in structures, negative transfer of

inference occurs and result in errors.

170. validity: the degree to which a test measures what it is meant to measure. There are four kinds of validity, i.e. content validity, construct validity, empirical validity, and face validity.

171. reliability: can be defined as consistency. There are two kinds of reliability, i.e. stability reliability, and equivalence reliability.

172. hypercorrection: overuse of a standard linguistic features, in terms of both frequency, i.e. overpassing the speakers of higher social status, and overshooting the target, i.e. extending the use of a form in linguistic environment where it is not expected to occur, For example, pronouncing ideas as[ai'dier],extending pronouncing post-vocalic[r] in an environment where it’s not supposed to occur.

金属学金相学名词解释

金属:具有正的电阻温度特性的物质。 晶体:物质的质点(原子、分子或离子)在三维空间作有规则的周期性重复排列的物质叫晶体。原子排列规律不同,性能也不同。 点阵或晶格:从理想晶体的原子堆垛模型可看出,是有规律的,为清楚空间排列规律性,人们将实际质点(原子、分子或离子)忽略,抽象成纯粹几何点,称为阵点或节点。为便于观察,用许多平行线将阵点连接起来,构成三维空间格架。这种用以描述晶体中原子(分子或离子)排列规律的空间格架称为空间点阵,简称点阵或晶格。 晶胞:由于排列的周期性,简便起见,可从晶格中取出一个能够完全反映晶格特征的最小几何单元来分析原子排列的规律性。这个用以完全反映晶格特征最小的几何单元称为晶胞。 多晶型转变或同素异构转变:当外部条件(如温度和压强)改变时,金属内部由一种晶体结构向另一种晶体结构的转变称为多晶型转变或同素异构转变。 空位:某一温度下某一瞬间,总有一些原子具有足够能量克服周围原子约束,脱离原平能位置迁移到别处,在原位置上出现空节点,形成空位。到晶体表面,称为肖脱基空位;到点阵间隙中,称弗兰克尔空位; 位错:它是晶体中某处有一列或若干列原子发生了有规律的错排现象,使长达几百至几万个原子间距、宽约几个原子间距范围内原子离开平衡位置,发生有规律的错动,所以叫做位错。基本类型有两种:即刃型位错和螺型位错。 晶界:晶体结构相同但位相不同的晶粒之间的界面称为晶粒间界,简称晶界。小角度晶界位相差小于10°,基本上由位错组成。大角度晶界相邻晶粒位相差大于10°,晶界很薄。 亚晶界和亚结构:分别泛指尺寸比晶粒更小的所有细微组织及分界面。 柯氏气团:刃型位错的应力场会与间隙及置换原子发生弹性交互作用,吸引这些原子向位错区偏聚。小的间隙原子如C、N 等,往往钻入位错管道;而大置换原子,原来处的应力场是受压的,正位错下部受拉,由相互吸引作用,富集在受拉区域;小的置换原子原来受拉,易于聚集在受压区域,即位错的上部。使畸变能降低,同时使位错难以运动,造成金属的强化。这就是利用溶质原子与位错交互作用的柯垂尔气团--柯氏气团。用以解释钢的脆化、强度提高等宏观现象。 元:组成合金的最基本的独立的物质,简称元 相:合金中结构相同、成分和性能均一并以界面互相分开的组成部分,称之为相。 组织:由于形成条件不同,形成具有不同形状、大小数量及分布的相相互结合而成的综合体。 固溶体:组元以不同比例混合后形成的固相晶体结构与组成合金的某一组元相同,这种相称固溶体 化合物:是构成的组元相互作用,生成不同与任何组元晶体结构的新物质 相图:是表示合金系中合金的状态与温度、压力与成分之间关系的一种图解。又称状态图或平衡图。

语言学重要知识点(胡壮麟版)

Language is a means of verbal communication. It is a system of arbitrary vocal symbols used for human communication. 1.Design features of language The features that define our human languages can be called design features which can distinguish human language from any animal system of communication.Arbitrariness refers to the fact that the forms of linguistic signs bear no natural relationship to their meanings.eg.the dog barks wowwow in english but 汪汪汪in chinese.Duality refers to the property of having two levels of structures, such that units of the primary level are composed of elements of the secondary level and each of the two levels has its own principles of organization.eg.dog-woof(but not w-oo-f)Creativity means that language is resourceful because of its duality and its recursiveness. Eg. An experiment of bee communication.Displacement means that human languages enable their users to symbolize objects, events and concepts which are not present (in time and space) at the moment of communication. 3. Origin of language The bow-wow theory In primitive times people imitated the sounds of the animal calls in the wild environment they lived and speech developed from that.The pooh-pooh theory In the hard life of our primitive ancestors, they utter instinctive sounds of pains, anger and joy which gradually developed into language. The “yo-he-ho” theory As primitive people worked together, they produced some rhythmic grunts which gradually developed into chants and then into language. 4.Linguistics is the scientific study of language. It studies not just one language of any one community, but the language of all human beings. 5. Main branches of linguistics ?Phonetics is the study of speech sounds, it includes three main areas: articulatory phonetics, acoustic phonetics, and auditory phonetics. ?Phonology studies the rules governing the structure, distribution, and sequencing of speech sounds and the shape of syllables. ?Morphology studies the minimal units of meaning – morphemes and word-formation processes. ?Syntax refers to the rules governing the way words are combined to form sentences in a language, or simply, the study of the formation of sentences. ?Semantics examines how meaning is encoded in a language. It is concerned with both meanings of words as lexical items and levels of language below the word and above it. ?Pragmatics is the study of meaning in context. It concerned with the way language is used to communicate rather than with the way language is structured. 6.Important distinctions in linguistics 1)Descriptive vs. prescriptive For example, ―Don’t say X.‖ is a prescriptive command; ―People don’t say X.‖ is a descriptive statement. The distinction lies in prescribing how things ought to be and describing how things are.Lyons 2)Synchronic vs. diachronic A synchronic study takes a fixed instant (usually at present) as its point of observation. Saussure’s diachronic description is the study of a language through the course of its history. E.g. a study of the features of the English used in Shakespeare’s time would be synchronic, and a study of the changes English has undergone since then would be a diachronic study. 3)Langue & parole langue: the linguistic competence of the speaker. parole: the actual phenomena or data of linguistics(utterances). Saussure 4)Competence and performance According to Chomsky,a language user’s underlying knowledge about the system of rules is called the linguistic competence, and the actual use of language in concrete situations is called performance. Competence 7.consonant is produced by constricting or obstructing the vocal tract at some places to divert, impede, or
