细胞生物学与细胞工程名词解释

Chapter 1 绪论1、细胞（cell）：细胞是由膜包围着含有细胞核（或拟核）的原生质所组成，是生物体结构和功能的基本单位，也是生命活动的基本单体。

2、细胞生物学（cell biology）：是研究和揭示细胞基本生命活动规律的学科，它从显微、亚显微及分子水平上研究细胞结构与功能，细胞增殖、分化、代谢、运动、衰老、死亡，以及细胞信号转导，细胞基因表达与调控，细胞起源与进化等重大生命过程。

3、细胞工程（Cell Engineering ）：以细胞为研究对象，运用细胞生物学、分子生物学等学科的原理和方法，按照人们的意志设计改造细胞的某些性状，从而培育出新的生物改良品种或通过细胞培养获得自然界中难以获得的珍贵产品的新兴生物技术。

Chapter 2 细胞的统一性与多样性1、原核细胞（prokaryotic cell）：没有明显可见的细胞核，同时也没有核膜和核仁，一般只有拟核。

2、真核细胞（eucaryotic cell）：是组成真核生物的细胞，具有典型的细胞结构，有明显可见的细胞核、核膜和核仁和核基质。

3、中膜体（mesosome）：中膜体又称间体或质膜体，是细菌细胞质膜向细胞质内陷折皱形成的，每个细胞有一个或数个；其中含有细胞色素和琥珀酸脱氢酶等呼吸酶；具有类似线粒体的作用，故称为拟线粒体。

4、细胞器（organelle）：存在于细胞中，用光镜、电镜或其他工具能够分辨出的，具有一定特点并执行特定机能的结构。

Chapter 3 细胞生物学研究方法1、分辨率（resolution）：是指能清楚的区分开两个质点间的最小距离。

2、显微结构（microscopic structure）：光镜下所见到的物体结构。

3、超微结构（ultrastructure）又称为亚显微结构（microscopic structure）：是在光学显微镜下观察不到而只能在电子显微镜下观察的结构。

Chapter 4 细胞质膜1、血影（Ghost）：将红细胞放入低渗溶液中，质膜破裂，同时释放出血红蛋白和其他可溶性蛋白，这时红细胞膜的仍然可以重新封闭起来，此时的红细胞被称为血影。

流体力学C-名词解释

Chapter 1 Fluid statics 流体静力学1. 连续介质假定(Continuum assumption)：The real fluid is considered as no-gap continuousmedia, called the basic assumption of continuity of fluid, or the continuum hypothesis of fluid. 流体是由连续分布的流体质点(fluid particle)所组成，彼此间无间隙。

它是流体力学中最基本的假定，1755年由欧拉提出。

在连续性假设之下，表征流体状态的宏观物理量在空间和时间上都是连续分布的，都可以作为空间和时间的函数。

2. 流体质点（Fluid particle ）: A fluid element that is small enough with enough moles to makesure that the macroscopic mean density has definite value is defined as a Fluid Particle. 宏观上足够小，微观上足够大。

3. 流体的粘性（Viscosity ）: is an internal property of a fluid that offers resistance to sheardeformation. It describes a fluid's internal resistance to flow and may be thought as a measure of fluid friction. 流体在运动状态下抵抗剪切变形的性质，称为黏性或粘滞性。

它表示流体的内部流动阻力，也可当做一个流体摩擦力量。

The viscosity of a gas increases with temperature, the viscosity of a liquid decreases with temperature. 4. 牛顿内摩擦定律（Newton’s law of viscosity ）：5. The dynamic viscosity （动力黏度）is also called absolute viscosity （绝对黏度）. The kinematicviscosity （运动黏度）is the ratio of dynamic viscosity to density.6. Compressibility （压缩性）：As the temperature is constant, the magnitude ofcompressibility is expressed by coefficient of volume compressibility (体积压缩系数) к , a relative variation rate （相对变化率） of volume per unit pressure.The bulk modulus of elasticity (体积弹性模量) E is the reciprocal of coefficient of volumecompressibility к.7. 流体的膨胀性(expansibility; dilatability)：The coefficient of cubical expansion (体积热膨胀系数) αt is the relative variation rate of volume per unit temperature change.8. 表面张力Surface tension : A property resulting from the attractive forces betweenmolecules. σ-----单位长度所受拉力9. 表面力 Surface force ——is the force exerted on the contact surface by the contacted fluidor other body. Its value is proportional to contact area. 作用在所研究流体外表面上与表du dzτμ=μνρ=面积大小成正比的力。

The two sounds are said to form a minimal pair.26. sequential rules: The rules to govern the combination of sounds in a particular language.27. assimilation rule: The rule assimilates one sound to another by copying a feature of a sequential phoneme, thus making the two phones similar.28. deletion rule: The rule that a sound is to be deleted although it is orthographically represented.29. suprasegmental features: The phonemic features that occur above the level of the segments----syllable, word, sentence.30. tone: Tones are pitch variations, which are caused by the differing rates of vibration of the vocal cords.31. intonation: When pitch, stress and sound length are tied to the sentence rather than the word in isolation, they are collectively known as intonation.Chapter 3: Morphology1. morphology: A branch of linguistics that studies the internal structure of words and rules for word formation.2. open class: A group of words, which contains an unlimited number of items, and new words can be added to it.3. closed class: A relatively few words, including conjunctions, prepositions and pronouns, and new words are not usually added to them.4. morpheme: The smallest unit of meaning of a language. It can not be divided without altering or destroying its meaning.5. affix: a letter or a group of letter, which is added to a word, and which changes themeaning or function of the word, including prefix, infix and suffix.6. suffix: The affix, which is added to the end of a word, and which usually changes the part of speech of a word.7. prefix: The affix, which is added to the beginning of a word, and which usually changes the meaning of a word to its opposite.8. bound morpheme: Morpheme that can not be used alone, and it must be combined wit others. E.g. –ment.9. free morpheme: a morpheme that can stand alone as a word.10. derivational morpheme: Bound morpheme, which can be added to a stem to forma new word.11. inflectional morpheme: A kind of morpheme, which are used to make grammatical categories, such as number, tense and case.12. morphological rules: The ways words are formed.

Critical Period Hypothesis: The hypothesis that the time span between early childhood and puberty is the critical period for language acquisition, during which children can acquire language without formal instruction successfully and effortlessly.6. under-extension: Use a word with less than its usual range of denotation.7. over-extension: Extension of the meaning of a word beyond its usual domain of application by young children.8. telegraphic speech: Childre n’s early multiword speech that contains content words and lacks function words and inflectional morphemes.9. content word: Words referring to things, quality, state or action, which have lexical meaning used alone.10. function word: Words with little meaning on their own but show grammatical relationships in and between sentences.11. taboo: Words known to speakers but avoided in some contexts of speech for reasons of religion, politeness etc.12. atypical development: Some acquisition of language may be delayed but follow the same rules of language development due to trauma or injury.Chapter 11 : Second Language Acquisition1. second language acquisition: It refers to the systematic study of how one person acquires a second language subsequent to his native language.2. target language: The language to be acquired by the second language learner.3. second language: A second language is a language which is not a native language ina country but which is widely used as a medium of communication and which is usually used alongside another language or languages.4. foreign language: A foreign language is a language which is taught as a school subject but which is not used as a medium of instruction in schools nor as a language of communication within a country.5. interlanguage: A type of language produced by second and foreign language learners, who are in the process of learning a language, and this type of language usually contains wrong expressions.6. fossilization: In second or foreign language learning, there is a process which sometimes occurs in which incorrect linguistic features become a permanent part of the way a person speaks or writes a language.14. overgeneralization: The use of previously available strategies in new situations, in which they are unacceptable.15. cross-association: some words are similar in meaning as well as spelling and pronunciation. This internal interference is called cross-association.16. error: the production of incorrect forms in speech or writing by a non-native speaker of a second language, due to his incomplete knowledge of the rules of thattarget language.17. mistake: mistakes, defined as either intentionally or unintentionally deviant forms and self-corrigible, suggest failure in performance.18. input: language which a learner hears or receives and from which he or she can learn.19. intake: the input which is actually helpful for the learner.20. Input Hypothesis: A hypothesis proposed by Krashen , which states that in second language learning, it’s necessary f or the learner to understand input language which contains linguistic items that are slightly beyond the learner’s present linguistic competence. Eventually the ability to produce language is said to emerge naturally without being taught directly.21. acquisition: Acquisition is a process similar to the way children acquire their first language. It is a subconscious process without minute learning of grammatical rules. Learners are hardly aware of their learning but they are using language to communicate. It is also called implicit learning, informal learning or natural learning.23. comprehensible input: Input language which contains linguistic items that are slightly beyond the learner’s pre sent linguistic competence.24. language aptitude: the natural ability to learn a language, not including intelligence, motivation, interest, etc.25. motivation: motivation is defined as the learner’s attitudes and affective state or learning drive.26. instrumental motivation: the motivation that people learn a foreign language for instrumental goals such as passing exams, or furthering a career etc.27. integrative motivation: the drive that people learn a foreign language because of the wish to identify with the target culture.28. resultative motivation: the drive that learners learn a second language for external purposes.29. intrinsic motivation: the drive that learners learn the second language for enjoyment or pleasure from learning.Chapter 12 : Language And Brain1. neurolinguistics: It is the study of relationship between brain and language. It includes research into how the structure of the brain influences language learning, how and in which parts of the brain language is stored, and how damage to the brain affects the ability to use language.2. psycholinguistics: the study of language processing. It is concerned with the processes of language acqisition, comprehension and production.7. aphasia: It refers to a number of acquired language disorders due to the cerebral lesions caused by a tumor, an accident and so on.13. spoonerism: a slip of tongue in which the position of sounds, syllables, or words is reversed, for example, Let’s have chish and fips instend of Let’s have fish and chips.14. priming: the process that before the participants make a decision whether the string of letters is a word or not, they are presented with an activated word.15. frequency effect: Subjects take less time to make judgement on frequently used words than to judge less commonly used words . This phenomenon is calledfrequency effect.16. lexical decision: an experiment that let participants judge whether a string of letter is a word or not at a certain time.18. priming effect: Since the mental representation is activated through the prime, when the target is presented, response time is shorter that it otherwise would have been. This is called the priming effect.。

生物化学名词解释

生物化学名词解释第一章蛋白质结构与功能1．肽单元（peptide unit）：参与肽键的6个原子—Cα1，C，O，N，H，Cα2位于同一平面，Cα1和Cα2在平面上所处的位臵为反式（trans）构型，此同一平面上的6个原子构成肽单元。

2．模体（motif）：由二个或三个具有二级结构的肽段，在空间上相互接近，形成一个特殊的空间构象, 并发挥特殊的功能，如锌指结构，β α β等。

模体通常有其特征性的氨基酸序列。

有的模体仅由几个氨基酸残基组成，如RGD (Arg-Gly-Asp)模体。

3．结构域（domain）：分子量较大的蛋白质常可折叠成多个结构较为紧密的区域，并各行其功能，称为结构域。

4．蛋白质等电点（Isoelectric point, pI）：在某一pH溶液中，蛋白质解离成正、负离子的趋势相等，即成为兼性离子，其所带的净电荷为零，此时溶液的pH值称为该蛋白质的等电点。

5．蛋白质的变性（denaturation of protein）：在某些物理和化学因素(如加热，强酸，强碱，有机溶剂, 重金属离子等)作用下，蛋白质的特定空间构象被破坏，从而导致其理化性质的改变和生物活性的丧失，称为蛋白质的变性。

变性不涉及一级结构中氨基酸序列的改变。

第二章酶1．酶的活性中心(active center of enzyme)：酶分子中与酶活性密切相关的基团(必需基团)在空间结构上彼此靠近，组成具有特定空间结构的区域，能与底物特异结合，并将其转变为产物，该区域称酶的活性中心。

辅酶参与酶活性中心的组成。

2．同工酶(isoenzyme)：催化相同的化学反应，但酶蛋白的分子结构、理化性质及免疫学性质不同的一组酶。

3．变构酶和变构调节(allosteric enzyme and allosteric regulation)：一些代谢物（变构效应剂）可与酶蛋白分子活性中心外的某一部位可逆地结合，使酶发生变构而改变其催化活性。
