One is the direct current。 the other is the alternating current. 電流有兩種，一種是直流電流，另一種是交流電流。 第 5節(jié) 翻譯練習(xí) 7 This chemical is poisonous. Others are poisonous, too. Some parts require a hard, tough metal and others may be made of softer metals. The coolant serves no other purpose than to remove excess heat. Some atomic nuclei undergo spontaneous disintegration while others do not. 冷卻劑除了排除多余的熱以外沒有任何其他用處。 這些化學(xué)制品有毒，別的化學(xué)制品也有毒。 有些零件需要由硬的韌性金屬制成，而有些則可由軟的金屬制成。 有的原子核會(huì)同時(shí)裂變，而另外一些卻不會(huì)。 第 5節(jié) 翻譯練習(xí) 8 Another method is available to increase the system capacity. Heat is always being transferred in one way or another, where there is any difference in temperature. 凡有溫差的地方，熱都會(huì)以這樣或那樣的方式傳輸。 還有另一種可增加系統(tǒng)容量的方法。 第 5節(jié) 翻譯練習(xí) 9 Some metals burn more readily than others. To specify a distance, we must use some unit of length. When an object is warmer than the surrounding region, it loses some of its heat by radiation. The particles require some a day to reach the earth. 為了確定距離，我們必須使用某種長度單位。 有些金屬比另一些金屬更容易燃燒。 當(dāng)一個(gè)物體比周圍環(huán)境熱時(shí)，該物體會(huì)通過輻射失去它的一些熱量。 這些粒子大約需要一天的時(shí)間才能到達(dá)地球。 it及 其句型的譯法 第 6節(jié) 翻譯練習(xí) 1 It moves or rotates by a fixed amount each time an electrical pulse is applied to it. To help avoid information overload, it (virtual convergence) will do this intelligently. The earth rotates as it travels through space. As current flows through a conductor, it sets up a magic field. 為了避免信息過載，它（虛擬連接）將會(huì)智能化地進(jìn)行操作。 對(duì)它每加一個(gè)電脈沖，它就移動(dòng)或旋轉(zhuǎn)一個(gè)固定的量。 地球在空間運(yùn)行時(shí)，它還要自轉(zhuǎn)。 電流通過導(dǎo)體，便產(chǎn)生磁場。 第 6節(jié) 翻譯練習(xí) 2 It is a $12billion industry whose factories, numbering in the hundreds, are found all over the world. It is twenty meters in height. 那個(gè)行業(yè)資金達(dá) 120億美元，工廠有上千家，遍布世界各地。 高度為 20米。 第 6節(jié) 翻譯練習(xí) 3 It is very far to the airport. It is raining hard. 到機(jī)場很遠(yuǎn)。 雨下得很大。 第 6節(jié) 翻譯練習(xí) 4 It is remended that the screw be used to increase accuracy of measurement. By using a laser, it is possible to throw very large and very clear television pictures on to a screen. It was pointed out that while the lead obtained from the disintegration of radium possessed all the characteristics of ordinary lead, it differed from it in atomic weight. 使用激光器，可 以將很大很清晰的電視圖像投射到屏幕上。 建議使用螺桿調(diào)節(jié)，以提高測(cè)量的精確度。 前已指出，雖然由鐳蛻變而獲得的鉛具有普通鉛的一切特性，但其原子量與普通鉛不同。 第 6節(jié) 翻譯練習(xí) 5 It necessitates careful design of the apparatus to get rid of the heat. It is unknown when to begin to make transportable transformers.
