Ⅳ. 段落翻译 ⑴变压器的初级绕组是馈有交变电流的线圈，而次级绕 组是通过变化的磁通传给有功率的线圈。初级和次级 的名称只取决于变压器连接的方式；任一个绕组均可 是初级，于是另一个就是次级了。 译文：The primary winding of a transformer is the coil which is fed with an alternating current, and [或： while] the secondary winding is the coil to which power is transferred via the changing flux. The designations of the primary and the secondary depends only on how the transformer is connected; either winding may be the primary, and the other is then the secondary.

练习1I、将下列句子译成汉语，注意句中有些冠词的特殊位置：1. In this case the current （电流）exists for only half the cycle （周期）2. In such a case there is no current flowing in the circuit （电路）3. Sensitivity （灵敏度）is a measure of how small a signal （信号）a receiver（接收机）can pick up and amplify （放大）to a level useful for com muni cati ons.4. emay be as small a positive con sta nt as you please.5. Even so fundamental a dimension（量纲）as time was measured extremely crudely with sand and water clocks hundreds of years ago.6. Nonlinear distortion （非线性失真）can be caused by too large an input signal.7. The method used is quite an effective one.8. A series （级数）solution of this kind of problem allows as close a calculation of the error as needed.II、将下列句子译成汉语，注意句中" and”和"or”的确切含义：1. Air has weight and occupies space.2. In this way less collector dissipation （集电极功耗）results, and the efficiency increases.3. We can go one step farther and take into account the nonzero slope of the actual curves.4. Try hard, and you will work the nut （螺母）loose.5. The first step in analyzing a physical situation is to select those aspects of it which are essential and disregard the others.6. This satellite was used for communications between the United States and Great Britain, France and Italy.7. Some physical quantities require only a magnitude and a unit to be completely specified. Thus it is sufficient to say that the mass of a man is 85 kg, that the area of a farm is 160 acres, that the frequency of a sound wave is 660 cycles/sec, and that a light bulb consumes electric energy at the rate of 100 watts.8. Geothermal energy, or energy from within the earth, can be used to generate electricity.9. The current in a capacitor （电容器）leads （导前）the voltage by 90o, or, the voltage lags the current by 90o.10. The message is a logical unit of user data, control data, or both.III 、将下列句子译成汉语，注意句中分数和倍数的正确译法：1. By varying V BE only a few hundredths of a volt, the base current （基极电流）can be changed significantly.2. The standard meter is accurate to about two parts in one billion.3. Cromatographic （层析的）techniques have been developed to detect air pollutants at concentrations （浓度）of one part per million or less.4. The volume coefficient （体膨胀系数）of a solid is almost exactly three times its linear coefficient.5. The demand for this kind of equipment in the near future will be 20 times what it is.6. The wavele ngth of this musical n ote （音符）is7.8 ft, over three times Ion ger tha n thewavelength of the same note in air （2.5 ft）.7. This causes the collector current （集电极电流）to change by a factor of approximately 38. This factor （因子）is now equal to 9, a reduction by a factor of 11.IV、将下列句子译成英语：1、火箭是由金属制成的。
