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.减小功率损耗是非常重要的,其方法是将一个复杂的电子线路集成为一小块。这使得释放电路工作时产生的热量变成一个难题。

2.The fundamental purpose of an electronic communication system is to transfer information from one place to another.
2.电子通信系统的基本作用是把信息从此地传送到彼地。

3.The first decision is on whether to choose a fixed point or a floating point device.
3.首先要决定的是选择定点器件还是浮点器件。

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.激光的用途极其广泛,令人瞩目,远远超出了设计第一代模型的科学家们的想象(尽管他们不愿承认),也极大地超出了早期科幻小说家的想象,这些小说家只是单纯地寻找一种未来武器(尽管他们也不愿意承认自己缺乏想象力)。

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种颜色(红色是最常见的激光颜色),还可以是许多种看不见的光,但每个激光器能且只能发出一种颜色的光。
