物理专业英语第6章翻译光波的干涉

物理专业英语第6章翻译光波的干涉The light intensity distribution generated when several light waves (member waves) meet does not equal to the sum of the light intensity distribution caused by each member wave alone, and the phenomenon of alternating light and dark appears.For example, in Young's double-hole interference (see Young's interference experiment), the subwave out of each small hole H1 or H2 is a member wave. When the hole is small, the light intensity distribution I1 (x) caused by the member wave from the hole H1 alone is roughly uniform in a considerable range; so is the light intensity distribution I2 (x) caused by the member wave from the hole H2 alone.The sum of the two is still roughly evenly distributed.In the light intensity distribution I (x) caused by the two member waves together, the change of light and shade with position x is very significant, which is obviously not equal to.Each member wave alone causes a roughly uniform distribution of light intensity, which is equivalent to requiring that each member wave itself has no obvious diffraction, because the diffraction alsocauses alternating light and dark stripes (see diffraction of light).Therefore, when a number of member waves meet in a certain region of space and the interference occurs, it should mean that the diffraction of each member wave can not be considered in that region.Note that the aforementioned light intensity is not the instantaneous value of the light field intensity (proportional to the amplitude square), but the average or integral value of the light field intensity within a certain time interval t; t depends on the performance of the detection means or device.For example, during human eye observation, t is the visual retention time; while shooting on film, t is the exposure time. The interference phenomenon usually shows a fairly steady stripe distribution of the light field intensity in space; sometimes, when the certain parameter of the interference device changes with time, the light intensity received at a certain fixed point changes alternately. The discovery of the interference phenomenon of light has historically played an indelible role in the evolution from the particle of light to the fluctuation of light.In 1801, T. Young proposed the principle of interference and first made adouble-slit interference experiment, and also explained the color of the film formation.In 1811, the D.F.J. Arago first studied the interference phenomenon of polarized light.Modern times, light interference has been widely used in precision measurement, astronomical observation, photoelastic stress analysis, automatic control in optical precision machining and many other fields.Generate conditions Only the two columns of light waves of the same frequency, the phase difference is constant, the vibration direction of the same direction of the coherent light source, can produce light interference.The light emitted by two ordinary independent light sources can not have the same frequency, let alone have a fixed difference, so, the interference phenomenon cannot produce. Specific methods In order to stabilize the light intensity distribution of the synthetic wave field over a time interval t, the frequency of each ① member wave v (and hence the wavelength) is the same; the initial phase difference between the two member wa ves of ② remains constant within t.Conditional ② means that several usually independent light sources meet without interference, even if they emit light at the same frequency.Thereason is that usually the light emitted by the light source is a large number of waves distributed irregularly in the initial phase, and each wave lasts no more than 10 seconds, that is, every 10 seconds or so, the initial phase of the wave is a random change.Moreover, the initial phase of the wave column emitted by any two independent light sources is again statistically independent.You can imagine that when these independent light source wave meet, only in a very short time to produce a certain stripe pattern, and every 10 seconds or so, with another pattern, so far not any detection or recording device can keep up with such sharp changes, thus observed the average effect of the large number of patterns, namely uniform light intensity distribution rather than light and dark stripes.However, modern special lasers have produced tens of kilometers of waves, even lasting on the order of 10 seconds.Therefore, it can be said that if a detector with the time-resolution ability t is shorter than 10 seconds (which is possible), the interference of the light waves emitted by two independent lasers of the same frequency can also be observed.In addition, taking the two-wave interference as an example also requires that: the amplitude of the ③ two waves mustnot differ greatly; the polarization surface of the ④ two waves at the superposition point must be roughly consistent. When the condition ③ is not satisfied, although the interference stripes can still arise in principle, but the light and dark difference of the stripes is very little, and the interference phenomenon is not obvious.Conditiona l ④ is necessary because when the polarization surface of the two optical waves is perpendicular to each other, the light intensity of the synthetic field is the same value and does not show alternating light and shade (to observe the light alternation, you must use the polarization element). The above four points are commonly known as coherence conditions.Two or more light sources or light waves that satisfy these conditions are called coherent light sources or coherent light waves.若干个光波（成员波）相遇时产生的光强分布不等于由各个成员波单独造成的光强分布之和，而出现明暗相间的现象。

物理专业英语组别：19组专业：物理学姓名：9.5 THE LORENTZ FORCEA charge moving in a magnetic field experiences a force which we shall call magnetic . The force is determined by the chang q,its velocity v ,and the magnetic inductionB at the point where the charge is at the moment of time being considered .The simplest assumption is that the magnitude of the force F is proportional to each of the three quantities q,v,and B .In addition ,F can be expected to depend on the mutual orientation of the vectors v and B .The direction of the vector F should be determined by those of vectors v and B.To”construct”che vector F form the scalar q and the vectors v and B ,let us find the vector of v and B and then multiply then multiply the result obtained by the scalar q.The result is the expressionq[vB (9.31）It has been established experimentally that the force F acting on a charge moving in a magnetic field is determined by the formulaFa=kq[vB] （9.32）Where k is a proportionality constant depending on the choice of the units for the quantities in the formula .It must be borne in mind that the reasoning which led us to expression(9.31)must by no means be considered as the derivation of Eq.(9.32)This reasoning does not have conclusive force .Its aim is to help us memorize Eq(9.32).The correctness of this equation can be established only experimentally .We must note that Eq.(9.32)can be considered as a definition of The magnetic induction B.The unit of magnetic induction B -the tesla-is determined so that the proportionality constant k in Eq.(9.32)equals unity .Hence,In SI units ,this equation becomesF=q[vB] (9.33）The magnitude of the magnetic force isF=qvBsin∂(9.34) Where ∂is the angle between the vectors v and B .It can be seen from Eq.(9.34) that a charge moving along the lines of a magnetic field does not experience the action of a magneticforce .The magnetic force is directed at right angles to the plane containing the vectors v and B.If the charge q is positive ,then direction of the force coincides with that of the vector [vB].Where q is negative ,the directions of the vectors F and [vB] are opposite (Fig.9.6).Since the magnetic force is always directed at right angles to the velocity of a charged particle ,it does no work on the particle .Hence ,we cannot change the energy of a charged particle by acting on it with a constant magnetic field .The force exerted on a charged particle that is simultaneously in an electric and a magnetic field isF=qE+q[vB] (9.35)This expression was obtained from the results of experiments by the Dutch physicist Hendrik Lorentz (1853~1928)and is called the Lorentz force.Assume that the charge q is moving with the velocity v parallel to a straight infinite wire along which the current I flows(Fig.9.7).According to Eqs .(9.30)and(9.34),the charge in this case experiences a magnetic force whose magnitude isF=qvB=qv b240I πμ (9.36) Where b is the distance from the charge to the wire .The force is directed toward the wire when charge is positive if the directions of the current and motion of the charge are the same ,and away from the wire if these directions are opposite (see Fig.9.7).When the charge is negative ,the direction of the force is reversed ,the other conditions being equal.Let us consider two like point charges q 1and q2 moving along parallel straight lines with the same velocity v that is much smaller than c (Fig.9.8).When v ∝c,the electric field does not virtually differ form the field of stationary charges (see Sec 。

袁加仁09027201专业英语翻译（127-133）热力学第一定律：能量守恒定律的再叙，经常运用于避免温度改变的系统中，系统增加的热能等于内能的增加加上系统对外做到的功。

绝热过程：膨胀或压缩过程任何地方都无热能的进入或离开系统。

热力学第二定律：热能永远不会自发地从低温物体流向高温物体。

同样，没有机器可以完全有效的将能量转化为做功。

一些输入的能量以热能的形式消散最终随着时间的流逝，所有系统趋于变得越来越混乱。

热机：一种将内能转化为机械做功的装置（设备）。

熵：系统混乱的度量，任何时候能量自由地从一个转移到另一个，转移方向朝着混乱度大的状态，因此朝着熵值增大的方向。

阅读材料温室效应如果地球不断地从太阳接收能量，也许你会惊讶为什么地球不变得越来越热，或是为什么地球平均气温不升高。

要保持长时期平均气温相对不变，地球必须丢失与接收到的相同数量的平均能量。

这通过想外太空辐射能量来完成的，大气通过这种方式对于防止日常气温的较大变化非常重要。

在没有大气层的月球上，日常气温从白天的或向阳面的100度到变化到阴暗面的-173度入射的太阳辐射使得大气和地表变暖，变暖的地球以红外线辐射的形式辐射能量。

大气中的水蒸气和二氧化碳有选择性地吸收能量，因此这些气体允许入射的可见太阳光通过，但却吸收或套住某些特定的红外线。

大气这种有选择性的吸收有助于保留地球的能量，所以我们没有像在月球上的日常气温的波动。

云层（小水滴）也通过吸收红外线辐射来帮助保持地球的温度。

在没有云层覆盖的地方，光线又冷又清。

因此，大气表层有保持地球日常气温变化的热静力学效应，我们把这种过程叫做温室效应。

玻璃的吸收特性类似于大气，如同应用于温室，玻璃允许可见的太阳光通过，阻止或吸收红外线辐射。

事实上，在这种情况下，温室的温暖基本上应归因于防止被玻璃包围的大地加热后的热气体的逃逸上。

夏天，涂上白色的玻璃板通过反射阳光和打开让热气体逃逸来控制温度。

封闭的温室内非常温暖，即使在冷天也是如此。

姓名：杨清军学号：09027217 我们已经算出u F 的值是力除以长度；因此，的结果是力。

根据公式（8.7）[F]=22][Lq ; [I]=T q ][ 使用公式（9.4）的结果，我们发现[k]=22LT 所以，在单位制中，k 可以写成公式K=21c (9.5) 式中c 为速率，把k 称之为电磁常数。

为了找到它的大小，我们使用在库伦定律和国际单位制中已制定的实验上的价值。

一个2107-⨯N/m 大小的力和3⨯104-dyn/cm 是相等的。

根据公式（9.1），当b=100cm 的时候，这是一个带有单位交流电的力。

因此2⨯104-=1001031032299⨯⨯⨯⨯⨯c 由此C=3⨯1010cm/s=3⨯108m/s (9.6) 电磁波的理论值和在真空中的光速相等。

在麦克斯韦理论中，存在一个与在真空中电磁波速率大小相等电磁常数c 。

同时根据真空中的光素为c 使麦克斯韦猜测光也是一种电磁波。

在公式（9.1）中的k 值在电磁单位制中是1和 1/c 2=1/(3⨯1010)2s 2/cm 2。

因此接下来的是1cgsm 的电流等于I cgse 10103⨯的电流A cgse cgsm I 10103110=⨯= (9.7) 用1s 乘以这个公式，我们会得到C cgse cgsm q q 10103110=⨯= (9.8) 因此cgse c cgsm I I 1= (9.9)相应的cgse cgsm q cq 1= (9.10) 存在一个关于常数0ε,0μ和c 的确定的公式，让我们找到结果的大小和方向。

根据公式（8.11），00με 的值是[][][]F L q 220=ε (9.11) 根据公式（9.2）[][][][][]2220q T F I b F u ==μ (9.12) 公式（9.11）和公式（9.12）可以得到[]222001νμε==L T (9.13) （v 是速度）联立公式（8.12）和（9.3），可得结果 00με的数值是()222287900103110410941m s m ⨯=⨯⨯⨯⨯=-ππεμ (9.14) 最后我们联立公式（9.6），（9.13）和（9.14），我们可以得到一个令我们感到兴趣的关系 2001c =με (9.15) 9.2 磁场电流贯穿其中与之相互作用的场叫做磁场。

物理专业英语翻译197-203

为了继续我们对电场的研究，我们必须了解自己用来描述矢量场的属性数学工具，这些工具被称为矢量分析，在本节中，我们应该处理矢量分析的基本概念和选定的公式。也证明了它的两个主要的定理即高斯定理（有时也调用了高斯的散度定理）和斯托克斯定理，矢量分析中使用的数量可以为一个流动的液体，速度矢量领域是最好用理想不可压缩液体的流动来说明，因此，我们将介绍这些数量，然后扩展得到的结果，任何性质的向量场
假设8.53式时，我们可以在直接通过其轴线的中心通过偶极子的垂直直线的磁场强度为
=
如式8.51所示当时，投影 =0因此，矢量是平行偶极子轴的从如下的公式可以得到，如图8.52所示，当时，投影的方向是正的方向，这标志着，反平行则是取决于向量。
偶极子磁场强度的情况它和偶极子的比例关系是速度超过了点电荷的电场的强度减少的。图8.11显示了发射线（实线）和等电位表面领域（虚线）偶极子，根据式8.50当 = 时存在r s。因此在平面直角偶极子轴并通过它的中间传递的一个零电位点消失，这可能有人预言，在在这个平面上的任何一点的电荷+q和-q的距离是相等的
,我们认为偶极子的相对能量将会是恒定的， =常数），对于点在x轴上来说，在y轴上和在z轴上的分量为零，因此得到，因此仅受力的分量不等于0，得以下的式子，这个结果似乎和我们的事实是一样的，这个领域的电场强度在点电荷+q和-q的数量是不同的，为，如图8.14所示，因此他们量之间的差异如图8.62所示，式子q 与这个式子是完全相同的，
这里的和在外电场的作用下+q和-q的潜在的力的作用，同性会减小线性矢量，假设X轴式如图8.13所示的方向，这样我们可以写成： = =- ，在图中便一看而知，在图8.13中显示了等于这段距离中的增量

物电系09级1班李春恒09090201164.4：INTERNAL ENERGY OF A SYSTEM系统的内能The intemal energy of a body is defined as the energy of this body(发自自身的能量，定义为身体的能量)———the kinetic energy of the body as a whole and the potential energy of the body in the external force field.(身体的动能,作为一个整体和潜在的能量中身体的外部力场)For example,(列如)in determining the internal energy of a mass of gas,(内在确定具有的大量的气体能量)we must no take into consideration the energy of motion of the gas together with the vessel containing it,(我们必须不考虑气体运动所包含的能量)and the energy due to the gas being to in the filed of the Earth’s gravitational forces气体的能量是由于受到啦地球的引力。

Hence， the concept of internal energy includes the kinetic energy of the chaotic motion of molecules ,因此，内能的概念就是分子无规则运动的动能。

The potential energy of interaction between the molecules,and the intramolecular energy.（还包括内部无规则运动的相互作用的势能和碰撞的能量）The internal energy of a system of bodies equals the sum of the internal energues of each of then separately and the energy of interaction between the bodies.一个系统的内能包括各个部分的能量之和。

2.1 Introduction(引言)We begin our study of the physical universe by examining objects in motion. Thestudy of motion . whose measurement. more than 400 years ago gave birth to physics. iscalled kinematics.Much of our understanding of nature comes from observing the motion of objects. Inthis chapter we will develop a description for the motion of a single point as it movesthrough space. Although a point is a geometrical concept quite different from everydayobjects such as footballs and automobiles, we shall see that the actual mot10n of manyobjects is most easily described as the motion of a single point (the "center of mass"). plusthe rotation of the object about that point. Postponing a discussion of rotation. let usbegin he-re with a description of a single point as it moves through space. Space and timeKinematics is concerned with two basic questions. "Where?" and "When?". Thoughthe questions are simple. the answers are potentially quite complicated if we inquire aboutphenomena outside our ordinary daily experiences. For example. the physics of very highspeeds, or of events involving intergalactic distances or submicroscopic dimensions. isquite different from our common-sense ideas. We will discuss the… interesting subjects inlater chapters. For the present we shall adopt the space and time of Newton-thoseconcepts we gradually developed as a result of our everyday experiences.Space is assumed to be continuously uniform and isotropic. These two terms meanthat space has no 'graininess' and that whatever its properties may be, they areindependent of any particular direction or location. in the words of Isaac Newton.' Absolute space . in its own nature . without relation to anything external . remains alwayssimilar and unmovable. " Every object in the universe exists at a particular location inspace. and an object may change its location Ly moving through space as time goes on. Wespecify the Location of a particular point in space by its relation to a frame of reference.Time, according to Newton, is also absolute in the sense that it "flows on" at auniform rate . We cannot speed it up or slow it down in any way. in Newton's words," Absolute. true. and mathematical time . of itself . and from its own nature . flows equablywithout relation to anything external. and by another name is called duration. " Time isassumed to be continuous and ever advancing. as might be indicated by a clock.Space and time are wholly independent of each other. though it is recognized that allphysical objects must exist simultaneously in both space and time.Remarkably . many of these traditional ideas turn out to be naive and inconsistent withexperimental evidence. The world is just different from the picture we form from ourcommon-sense. intuitive ideas. Space and time, by themselves. arc concepts that arcdifficult (or perhaps impossible) to define in terms of anything simpler. However. we canmeasure space and time in unambiguous ways. We define certain operations by which weobtain numerical measurements of these quantities using rulers and clocks. based uponstandard units of space and time.For many years. our standard of time was based on astronomical observations of the earth'srotation. Because of the variations in the earth’s rotation . in 1967 the 13th General Conference onWeights and Measures. attended by 38 nations. adopted an atomic standard for time.Similarly. our former standard of length was the distance between two marks onplatinum-iridium bar. kept at Sevres. France. in 1960. the fundamental length standardwas redefined in terms of the wavelength of light emitted during a transition between two.The standard units of time and length may be described as follows:An interval of time. The fundamental unit is the second (s) . which by internationalagreement is defined as the duration of 9 192 631 770 periods of radiation corresponding tothe transition between the two lowest energy levels in the atomic isotope cesium 133.An interval of length. The fundamental unit is the meter (m). which is defined independently of the time interval Before 1983 . by international agreement the meter wasdefined as exactly 1 650 763. 73 wavelengths of the orange light emitted from the isotopekrypton 86. in November 1983. the length standard was defined as the distance that lighttravels in a vacuum in l1299 792 458 second.l angstrom(A) -. 10-l0 m l micron (u or um)10-6 m2.1简介（引言）我们开始研究宇宙的物理研究物体的运动。

对于一个恒253—259定的磁场，环绕的矢量H 关于j H =∇相当于一点的传导电流的散度为j H =∇。

矢量j 与电荷密度在同一点，他们之间的关系为tj ∂∂-=∇ρ。

电磁场的恒定跟电荷密度和电流密度有关而不取决于时间，在这种情况下，发散的电流密度j 等于0，因此，闭合的电流是没有能量的。

让我们看看j H =∇是否也适合于时间的领域。

我们可以考虑当一个电容由恒压提供电源时，其内电流的流动方向。

电流会随时间的变化而变化的（电流等于0时，则电容器的电压为恒压U ）。

传导电流在电容器的两板之间产生。

让我们把闭合线圈中和电容器中的电流与表面积的积分会等于电流密度j H =∇与表面积的积分。

⎰⎰=∇s jds s ds H 11][ 左边的公式是从斯托克原理得到的，故我们得到矢量H 与环量Γ有关。

（I 是电容器提供的电流）经过相同的运算后，表面积不相交于S 2，我们可以得到一个关系。

02==⎰⎰Γs jds Hds 这个结果我们证明了j H =∇在空间时间的领域中是正确的。

但是，在时间的基础上，我们需要在方程式上再加一个加数，对于静止系统，就没有这个加数。

对于j H =∇在非静止系统中是错误的也给出一个原因，让我们把j H =∇进行双重散度的计算，j H ∇=∇∇][，这个散度一定等于0.我们用这个方式得到的矢量j 的散度恒为零，但这个结论与t j ∂∂-=∇ρ的连续性相矛盾。

的确，在非静止系统中的过程，ρ会随时间改变而改变。

在这种情况下得到了t j ∂∂-=∇ρ，矢量j 的散度为零。

把j H =∇和tj ∂∂-=∇ρ代入麦克斯韦方程组，需要在右边方程增加一个加数j H =∇，这个加数能够让电流密度的量度得到十分自然的计算。

麦克斯韦把它叫做位移电流的密度。

因此，从麦克斯韦方程组得知，j H =∇应该是：d j j H +=∇ （10.8）传导电流和位移电流的总和统称为实际电流，而实际电流的电流密度为：d tot j j j +=∇ （10.9）若是假设位移电流向散度等于传导电流的散度的负值。

英语翻译作业英文录入13.2.3 Coulomb ’s Law （库仑定律）库伦定律(1736-1806)在测量电荷之间电场力大小时利用了他特有的发现扭秤。

在库伦的理论中，电荷的大小远远小与它们之间的距离则以至于可以把它们当作点电荷。

库伦利用电荷之间的感应这样的方法产生了等效的电荷点电荷。

例如，任意球体中有开始电荷0q ，当其与另一个球体进行单次接触放电后，其带电量会减少2/0q 然后让两个球体接触。

库伦实验的结果和其他人的总结都在库伦定律。

电荷之间的作用力的方向沿着这两个点电荷的连线。

它与这两个电荷的距离的平方成反比，两个电荷的电量的乘积成正比。

如果是同名电荷相斥，异名电荷则相吸。

电荷1q 和另一个电荷2q 之间的电场力的大小可以表示为给定的2212121r q q k F =21r 是1q 和2q 之间的距离，k 是一个实验确定的常数叫做库伦常量，它的值为229229/100.9/109880.8C m N C m N k •⨯≈•⨯=库仑定律给出矢量方程为e F r r q q k 212212121=e r 21是一个单位矢量，方向指向从1q 到2q ，F 21是1q 在2q 上的力。

如果1q 和2q 是同号的，2q 受的力方向和e r 21同向，而且总是背向1q 。

如果1q 和2q 是异号的，2q 受的力方向和e r 21反向，而且总是指向1q 。

从牛顿第三定律，我们看到从2q 对1q 得电场力大小等于1q 对2q 的力和方向相反。

就是F F 1221-=。

库伦常量k 也可以写作041πε=k0ε是真空介电常数，值为22120/1085.8m N C •⨯=-ε因此在真空中库仑定律也写作e F r r q q 21221021214πε=14.2.1 Gauss ’s Law （高斯定理）高斯定理，是叙述电场在一个封闭曲面的表面上的净电荷，是静电研究领域重要的定理。

总之，高斯定理陈述的是真空中的电场穿过任意闭合曲面的电通量等于闭合曲面内部净电荷除以0ε。

大学物理专业英语翻译作业答案部分

166页翻译：奇数和偶数菲涅耳波带的振动是反相位的，因此，它们会相互削弱。

如果我们在光路上放置一块（圆形）碟板，这块平板可以遮挡所有的奇数或偶数半波带，光强在P点将大幅增长。

这样一块碟板，被称为一个波带板，它的功能类似于聚光透镜。

图7.9显示了一块碟板遮挡了偶数半波带（的情形）。

通过将偶数（或奇数）波带振荡的相位改变π，而不是遮挡这些半波带，会产生更好的效果。

这可以借助一个透明板做到，这个透明板在其对应的奇数或偶数半波带处会选择一个合适的厚度。

这样一个板叫做相位波带板。

与振幅波带板遮挡区域相比，一块相位板增加额外2倍振幅，和增加4倍的光强。

进程，也就是系统从一个状态到另一个状态的变换，是与打破系统的平衡相关的。

因此，当系统中出现了一个进程，就意味着它会经过一系列的不平衡态。

回到我们所考虑的用活塞压缩密闭容器中气体的进程，可以得出结论：通过推动活塞来破坏平衡的程度越大，气体越快被压缩。

而如果我们非常缓慢地移动活塞，平衡的破坏将变得无关紧要（忽略不计），而每一个不同点的压强也只会与某个平均压强值p有微小差异。

在有限的情况下（一定情况下），如果气体被无限慢地压缩，那样在每一个时刻都会有一个确定的压强值。

所以，在这样的情况下，气体状态在每一个时刻都是平衡的，而这些无限慢的进程将会组成一系列的平衡态。

根据公式2.26，保守力对质点所做的功等于质点的势能减少量，另一种说法就是，做功是以消耗物体所储备的势能为代价的。

由公式2.27，我们可以推出，势能是由某个未知而不变的量E(p,0)准确地决定的。

然而这个说法没有任何的意义，因为所有物理规律的确定既在于该物体在两个位置的不同势能Ep值，也在于Ep函数的导数值。

在实际中，一个物体在某个位置的势能可以被视为零，然后在其他位置上势能就是相对于这个位置而言的。

理解了关于Ep（x,y,z）的函数之后，我们就可以确定作用于场中某一质点的力。

让我们考虑一个质点平行于X轴位移了dX的位移。
