* All matter, solid, gaseous or liquid, is made up of extremely tiny particles called molecules.
一切物质,不论是固态、气态还是液态都是由极其微小的叫做分子的粒子所构成的。
4. 当or连接句子时,可译为“否则”,有时or后会出现else。如:
* Sufficient commutation time must be allowed for the thyristors, or commutation failure will occur.
必须给可控硅整流器充分的换流时间,否则会发生换流失败。
* The turns of wire must be insulated from each other and from the iron, or the current will flow through short-circuits instead of flowing around the coil.
各匝导线必须相互绝缘并与铁芯绝缘,否则电流将短路,而不是围绕线圈流动。
* The temperature must not exceed 650°C, or else the metal will melt.
温度不能超过650°C,否则,此金属会熔化。
5. 当or连接数字,表示不确定的数字概念时,可译为“大约”、“左右”等。如:
* The particles require one or two days to reach the earth.
这些粒子大约需要ー两天的时间才能到达地球。
* Lipoid A is reputed to contain only 40% or 50% of fatty acids.
据说类脂物A只含有大约40% — 50%的脂肪酸。
