The other process of droplet growth is by collision and coalescence.

云滴增长的另一个过程是各云滴间的碰撞和并合。

The rate of droplet growth under different conditions can be evaluated.

可以计算在不同条件下的云滴增长率。

Such clouds would persist for an unusually long time because small water droplets are less likely than big ones to turn into rain.

这类由较多小云滴组成的云所能维持的时间之久异乎寻常，因为大云滴比小云滴更容易转变为雨滴。

The droplets are not uniform in size, but the spread is not so great.

虽然云滴大小并不均匀，但差异也不很大。

If it is correct, then cosmic rays may create clouds with more small droplets than would otherwise be the case.

如果该理论正确，那么宇宙射线形成的云同其他方式形成的云相比，小云滴的数量更多。

It is legitimate to envisage a more or less one-to-one correspondence between cloud nucleus concentration and the concentration of cloud droplets.

拟想云核浓度与云滴浓度之间有或多或少的一一对应关系是合理的。
