（二）分母：denominator
（一）分子双语例句
1、各种物质，不论它是什么，都是由一些称为分子的很小的粒子构成的。
Every substance, no matter what it is, is composed of very small particles called molecules.
2、所以这有三个概率,对应于分子的这个能量，而这只有一个。
So there are three possibilities in which the molecule could have this energy, and only one this.
3、分子在这个状态,或处于这些状态之一的。
That the molecules are in this state or in any of these states.
4、一个无限小的量，看看能得到什么，一旦我这样做，现在有多少分子能到达这个较高的能级？
An infinitesimal amount, to look at the derivative. Once I do this, how many molecules are in this higher level now?
5、但它们几乎都没有,和不同种分子发生相互作用。
But hardly any of them experience interactions with the unlike molecules.
（二）分母双语例句
1、第一步是使分数的分母有理化。
The first step is to rationalize the denominator of a fraction.
2、分数值与分母值成反比例。
The value of a fraction is inversely proportional to that of the denominator.
3、这种变化意味着现在处理器繁忙时间所占百分比的分子和分母都是随机的，因此这个值在生产虚拟环境中没有用处。
This variation means that the processor busy rate now has a random denominator and a random numerator, which renders this value fairly useless in a production virtual world.
