【正文】 插入語(yǔ)主要起承上啟下的作用或表示作者的態(tài)度。 The start bit of a character is placed in the space level, and the stop bit the mark level. 4. 在計(jì)算機(jī)與其顯示終端之間最為常見(jiàn)的串行接口是異步串行接口，而在電路交換機(jī)與其電話終端之間最為常見(jiàn)的串行接口是同步串行接口。 3. 我們將字符的起始位設(shè)置成空號(hào)電平，而將字符的終止位設(shè)置成信號(hào)電平。 并非所有數(shù)據(jù)都要核對(duì)。 The coder, a unit that converts amplitude values to a set of pulses, is very important to digital transmission. 5. 編碼的問(wèn)題是一個(gè)極為重要的問(wèn)題。 5. 編碼的問(wèn)題是一個(gè)極為重要的問(wèn)題。 ＊ 這時(shí)分詞短語(yǔ)的邏輯主語(yǔ)經(jīng)常省略。UNIT 1 同位語(yǔ)跟在所修飾的名詞之后，可表示相同的事物或人，也可對(duì)該名詞進(jìn)行說(shuō)明。 ＊ 被省略的邏輯主語(yǔ)多數(shù)情況下指的是主句的主語(yǔ)或逗號(hào)前整個(gè)句子的含義，點(diǎn)也有少數(shù)列外。 6. PCM這個(gè)術(shù)語(yǔ)是一個(gè)通信術(shù)語(yǔ)。 The problem of coding is a very important one. 6. PCM這個(gè)術(shù)語(yǔ)是一個(gè)通信術(shù)語(yǔ)。 ?Both the transistors on the table are not good. 桌子上兩個(gè)晶體管并不都是好的。 4. 在計(jì)算機(jī)與其顯示終端之間最為常見(jiàn)的串行接口是異步串行接口，而在程控交換機(jī)與其電話終端之間最為常見(jiàn)的串行接口是同步串行接口。 By far the most popular serial interface between a puter and its CRT terminal is the asynchronous serial interface, and between a circuit switch and its telephone terminal, the synchronous one. 5. 由發(fā)送器所送出的停止位總是被設(shè)置成信號(hào)電平。 ?Conversely, substances of small resistivity are good conductors. ?This device consists in fact of five parts. ?Who made the first generator in the world, then? ?An increase in temperature, though, tends to make a gas expand. ?Roughly speaking, microwaves are radio waves whose wavelength is less than 30 cm. ?Velocity, we have noted before, is a vector quantity. ?A few kiloohms will, I believe, be enough. 常用的插入語(yǔ)有： 一般來(lái)說(shuō)， general speaking, 更為重要的是， more important, 最為重要的是， the most important, 人們斷言， it has been claimed, 我們將會(huì)看到， it will be noticed, we can see, 我認(rèn)為， I believe, 確實(shí)， it is true, 我們認(rèn)為， we think, 倒裝句 ?Among the experiments to be conducted is a search for Martian life ?In the drawing are another pair of similar right triangles. ?Before long, out came the water. ?There exists a very important relationship between current, voltage and resistance. ?There has been developed a method for producing vastly more powerful rays. ?Orbiting the nucleus are negatively charged particles called electrons. 英譯漢練習(xí) 1. These forces act on the electrons able to move freely within the wire. 2. The more the spring is stretched, the greater is the force necessary to stretch it. 3. Neutron has a mass slightly larger than that of a
