Overall, it is a process that converts light energy into chemical energy that is stored in the molecular bonds. From the point of view of chemistry and energetics, it is the opposite of cellular respiration. Whereas 然而 cellular细胞的 respiration 呼吸is highly exergonic吸收能量的and releases energy, photosynthesis光合作用requires energy and is highly endergonic.光合作用只发生在含有叶绿素的绿色植物细胞,海藻,某些原生动物和细菌之中。

总体来说,这是一个将光能转化成化学能,并将能量贮存在分子键中,从化学和动能学角度来看,它是细胞呼吸作用的对立面。

细胞呼吸作用是高度放能的,光合作用是需要能量并高吸能的过程。

Photosynthesis starts with CO2 and H2O as raw materials and proceeds through two sets of partial reactions. In the first set, called the light-dependent reactions, water molecules are split裂开 (oxidized), 02 is released, and ATP and NADPH are formed. These reactions must take place in the presence of 在面前 light energy. In the second set, called light-independent reactions, CO2 is reduced (via the addition of H atoms) to carbohydrate. These chemical events rely on the electron carrier NADPH and ATP generated by the first set of reactions.光合作用以二氧化碳和水为原材料并经历两步化学反应。

第二章课文翻译在开始深入电路分析之前,我们需要对电路设计有一个总的认识,尤其是电路的设计部分,这个概述的母的是为你提供一个关于电路分析在整个电路设计中的作用的认识。

所有的工程设计都是为了迎合某种需要而展开的,正如图表1.1所示。

这种需要可能会来源于渴望对已经存在的某种产品的改进,也可能来源开发新的东西。

对于需求的细致评估可以使得整个被提出的设计中的那些可以测量要素的具体化。

一旦这个设计被提出来之后,设计的具体化可以使我们评估设计的结果满足需要的要求。

下面是设计的概念,这个设计的概念源自对设计具体化的彻底的裂解和对需要的完全洞悉,同时也源自知识和经验。

这个概念可以理解为一个纲领,抑或是明文描述,或者是一些其他的形式。

通常,下一步是将这个概念转化为数学模型,一个使用的电子和计算机系统的数学模型就是一个电路模型。

组成电路的原件被称作是理想电路元件。

一个理想的电路元件是一个数学模型上的电子元件,例如一个干电池或一个白炽灯泡。

重要的是,理想电路元件中使用的电路模型,代表的行为达到实际电气元件可接受的准确度。

这本书关注的焦点是,电路分析的工具应用与电路分析。

电路分析是基于数学建模的基础之上用来分析电路模型和分析电路中的理想电路元件,在设计要的行为和描述的行为之间的比较,可以直接导致优化电路模型和其中的电路元件。

一旦要求的行为和电路模型描述的行为达成一致,一个物理模型就可以被创建了。

根据实际的电子元件建立的物理模型其实就是一个电子系统。

现有的测量技术其实决定着实际的物理系统的行为,实际的行为与设计要求的行为和数学模型所描述的行为相比,结果可能会导致对电路模型或者数学模型或者两者的进一步优化。

最终,通过对这个模型中的组成部分和整个系统的反复的优化,将可能会产生一个设计要求的精确匹配的设计,进而满足需要。

通过以上的描述,我可以清晰的认识到电路分析在电路设计过程中扮演者重要的角色。

因为电路分析应用于电路模式,实践工程师会努力尝试在第一次的优化过程中使用成熟的电路模型,使所产生的设计来满足设计规范;你可任务这些都是成熟的电路模型。

第二章第一篇To say that we live in an age of electronics is an understatement. From the omnipresent integrated circuit to the equally omnipresent digital computer, we encounter electronic devices and systems on a daily basis. In every aspect of our increasingly technological society—whether it is science, engineering, medicine, music, maintenance, or even espionage—the role of electronics is large, and it is growing.谈论关于我们生活在一个电子学时代的论调是一种空泛的论调。

从无处不在的集成电路到同样无处不在的数字计算机,我们在日常活动中总会遇到电子设备和电子系统。

在我们日益发展的科技社会的方方面面——无论是在科学、工程、医药、音乐、维修方面甚至是在谍报方面——电子学的作用是巨大的,而且还将不断增强。

In general, all of the tasks with which we shall be concerned can be classified as "signal-processing “tasks. Let us explore the meaning of this term一般说来,我们将要涉及到的工作被归结为“信号——处理”工作,让我们来探究这个术语的含义吧。

A signal is any physical variable whose magnitude or variation with time contains information. This information might involve speech and music, as in radio broadcasting, a physical quantity such as the temperature of the air in a room, or numerical data, such as the record of stock market transactions. The physical variables that can carry information in an electrical system are voltage and current. When we speak of "signals", therefore, we refer implicitly to voltages or currents. However, most of the concepts we discuss can be applied directly to systems with different information-carrying variables. Thus, the behavior of a mechanical system (in which force and velocity are the variables) or a hydraulic system (in which pressure and flow rate are the variables) can often be modeled or represented by an equivalent electrical system. An understanding of the behavior of electrical systems, therefore, provides a basis for understanding a much broader range of phenomena. 信号就是其与时间有关的量值或变化包含信息的任何物理变量。

The ratio of the length and the width of the same book does not vary when the measurement unit changes.(5)60 percent of students in a school are female students, which mean that 60 students out of every 100 students are female students.2.22.初等几何:elementary geometry 三角学:trigonometry 余弦定理:Law of cosines 勾股定理/毕达哥拉斯定理:Gou-Gu theorem/Pythagoras theorem 角:angle 锐角:acute angle 直角:right angle 同终边的角:conterminal angles 仰角:angle of elevation 俯角:angle of depression 全等:congruence 夹角:included angle 三角形:triangle 三角函数:trigonometric function直角边:leg 斜边:hypotenuse 对边:opposite side 临边:adjacent side 始边:initial side 解三角形:solve a triangle 互相依赖:mutually dependent 表示成:be denoted as 定义为:be defined as3.(1)Trigonometric function of the acute angle shows the mutually dependent relations between each sides and acute angle of the right triangle.(3)If two sides and the included angle of an oblique triangle areknown, then the unknown sides and angles can be found by using the law of cosines.(5)Knowing the length of two sides and the measure of the included angle can determine the shape and size of the triangle. In other words, the two triangles made by these data are congruent.4.(1)如果一个角的顶点在一个笛卡尔坐标系的原点并且它的始边沿着x轴正方向,这个角被称为处于标准位置.(3)仰角和俯角是以一条以水平线为参考位置来测量的,如果正被观测的物体在观测者的上方,那么由水平线和视线所形成的角叫做仰角.如果正被观测的物体在观测者的下方,那么由水平线和视线所形成的的角叫做俯角.(5)如果我们知道一个三角形的两条边的长度和对着其中一条边的角度,我们如何解这个三角形呢?这个问题有一点困难来回答,因为所给的信息可能确定两个三角形,一个三角形或者一个也确定不了.2.32.素数:prime 合数:composite 质因数:prime factor/prime divisor 公倍数:common multiple 正素因子: positive prime divisor 除法算式:division equation 最大公因数:greatest common divisor(G.C.D) 最小公倍数: lowest common multiple(L.C.M) 整除:divide by 整除性:divisibility 过程:process 证明:proof 分类:classification 剩余:remainder辗转相除法:Euclidean algorithm 有限集:finite set 无限的:infinitely 可数的countable 终止:terminate 与矛盾:contrary to3.(1)We need to study by which integers an integer is divisible, that is , what factor it has. Specially, it is sometime required that an integer is expressed as the product of its prime factors.(3)The number 1 is neither a prime nor a composite number;A composite number in addition to being divisible by 1 and itself, can also be divisible by some prime number.(5)The number of the primes bounded above by any given finite integer N can be found by using the method of the sieve Eratosthenes.4.(1)数论中一个重要的问题是哥德巴赫猜想,它是关于偶数作为两个奇素数和的表示.(3)一个数,形如2p-1的素数被称为梅森素数.求出5个这样的数.(5)任意给定的整数m和素数p,p的仅有的正因子是p和1,因此仅有的可能的p和m的正公因子是p和1.因此,我们有结论:如果p是一个素数,m是任意整数,那么p整除m,要么(p,m)=1.2.42.集:set 子集:subset 真子集:proper subset 全集:universe 补集:complement 抽象集:abstract set 并集:union 交集:intersection 元素:element/member 组成:comprise/constitute包含:contain 术语:terminology 概念:concept 上有界:bounded above 上界:upper bound 最小的上界:least upper bound 完备性公理:completeness axiom3.(1)Set theory has become one of the common theoretical foundation and the important tools in many branches of mathematics.(3)Set S itself is the improper subset of S; if set T is a subset of S but not S, then T is called a proper subset of S.(5)The subset T of set S can often be denoted by {x}, that is, T consists of those elements x for which P(x) holds.(7)This example makes the following question become clear, that is, why may two straight lines in the space neither intersect nor parallel.4.(1)设N是所有自然数的集合,如果S是所有偶数的集合,那么它在N中的补集是所有奇数的集合.(3)一个非空集合S称为由上界的,如果存在一个数c具有属性:x<=c对于所有S中的x.这样一个数字c被称为S的上界.(5)从任意两个对象x和y,我们可以形成序列(x,y),它被称为一个有序对,除非x=y,否则它当然不同于(y,x).如果S和T是任意集合,我们用S*T表示所有有序对(x,y),其中x术语S,y属于T.在R.笛卡尔展示了如何通过实轴和它自己的笛卡尔积来描述平面的点之后,集合S*T被称为S和T的笛卡尔积.2.52.竖直线:vertical line 水平线:horizontal line 数对:pairs of numbers 有序对:ordered pairs 纵坐标:ordinate 横坐标:abscissas 一一对应:one-to-one 对应点:corresponding points圆锥曲线:conic sections 非空图形:non vacuous graph 直立圆锥:right circular cone 定值角:constant angle 母线:generating line 双曲线:hyperbola 抛物线:parabola 椭圆:ellipse退化的:degenerate 非退化的:nondegenerate 任意的:arbitrarily 相容的:consistent 在几何上:geometrically 二次方程:quadratic equation 判别式:discriminant 行列式:determinant3.(1)In the planar rectangular coordinate system, one can set up aone-to-one correspondence between points and ordered pairs of numbers and also a one-to-one correspondence between conic sections and quadratic equation.(3)The symbol can be used to denote the set of ordered pairs(x,y)such that the ordinate is equal to the cube of the abscissa.(5)According to the values of the discriminate,the non-degenerate graph of Equation (iii) maybe known to be a parabola, a hyperbolaor an ellipse.4.(1)在例1,我们既用了图形,也用了代数的代入法解一个方程组(其中一个方程式二次的,另一个是线性的)。

核电专业英语 第二章 辐射 翻译

核电专业英语 第二章 辐射 翻译

第二章辐射2.1放射性放射性是一个普遍的自然现象,它的发现早于核裂变40年以上发现,放射性是对生命组织有害的。

然而,人类和其他动物到目前为止都还没有进化出能监测到它危害的感觉器官。

公众恐惧的核能大部分原因也正是因为放射性的不可见特性。

然而,科学仪器,已发展到对所有类型的辐射均可灵敏探测,且广泛用于核能活动过程中以确保工人和公众不在有放射性危害的环境中。

辐射的潜在有害特性是它可以电离我们体内原子的能力,即辐射可以打击出原子中的电子,进而细胞改变其化学性能。

大剂量的辐射可以导致组织死亡,在较低的辐射水平情况下,如果电离发生在细胞分裂过程中就可能引起基因突变。

在大多数情况下,这也会导致细胞死亡,但也存在受到伤害的细胞发生基因突变后在体内存活下来,进而可能导致各种癌症的风险。

癌症是一个非常可怕的疾病,这是公众对核能担忧的另一个原因。

放射性是自发的,自然的和随机的过程,可以三种基本的形式衰变,称为α,β和γ。

α辐射是从核中发射一簇质子和中子相当于一个氦原子核(两个质子和两个中子)。

由于α相对较大的质量,α粒子能携带相当大的能量,足以对遇到的任何生物组织造成严重损害。

然而,也因为它的体积大,这种辐射很容易被阻挡的,比如几厘米的空气或几张纸就可以阻挡α射线。

对放射性相对不敏感的皮肤对α也是一道屏障,所以α辐射的外照射不太危险。

来自α辐射真正的风险是α发射物质被吸入肺或消化系统。

β辐射是由非常快的电子组成的。

它对生物组织的伤害潜能低于α辐射,但其穿透能力要强于α。

β辐射可以用一片玻璃或金属箔屏蔽。

没有这样的屏蔽的话,β辐射外照射源会令人担忧。

γ射线是非常高能量的光的形式。

不同于其他两种形式辐射是它不带电,也没有质量。

它本质上是一种非常高能量的X射线,而且对生物组织的伤害根本不同于α或β辐射。

γ射线受到特别关注是因其极其强的穿透能力。

几厘米厚的铅或几米厚的混凝土才能完全屏蔽γ辐射。

我们很容易受到不同形式的放射性(有些情况下需要屏蔽)的危害。
