1.The reduction in power dissipation is particularly important where a complex circuit is to be concentrated into a small space.The problem of extracting the heat generated in the circuit may then be a difficult one.
1.減小功率損耗是非常重要的，其方法是將一個(gè)復(fù)雜的電子線路集成為一小塊。這使得釋放電路工作時(shí)產(chǎn)生的熱量變成一個(gè)難題。

2.The fundamental purpose of an electronic communication system is to transfer information from one place to another.
2.電子通信系統(tǒng)的基本作用是把信息從此地傳送到彼地。

3.The first decision is on whether to choose a fixed point or a floating point device.
3.首先要決定的是選擇定點(diǎn)器件還是浮點(diǎn)器件。

4.The range of uses for the laser is striking,going far beyond the original ideas of the scientists who developed the first models(though they don't like to admit this),as well as vastly beyond the visions of the early science-fiction writes,who more often than not were simply looking for a futuristic weapon(though they too are not about to admit their lack of vision).
4.激光的用途極其廣泛，令人矚目，遠(yuǎn)遠(yuǎn)超出了設(shè)計(jì)第一代模型的科學(xué)家們的想象（盡管他們不愿承認(rèn)），也極大地超出了早期科幻小說家的想象，這些小說家只是單純地尋找一種未來武器（盡管他們也不愿意承認(rèn)自己缺乏想象力）。

5.Laser beams have been produced in every color of the rainbow(red is the most common laser color),as well as in many kinds of invisible light,but each laser can emit one color and one color only.
5.激光束可以是彩虹中的每一種顏色（紅色是最常見的激光顏色），還可以是許多種看不見的光，但每個(gè)激光器能且只能發(fā)出一種顏色的光。
