1·The vertical distribution of cloud droplet spectra has three typical sorts.

云滴谱的垂直分布是典型的3种类型；

2·Cloud droplet spectra could be formed in a comparatively low level above cloud base and developed later in higher levels.

在积云云底之上较底的高度上可以较早地形成较为稳定的云滴谱谱型，而在较高的高度上则要晚一些。

3·In fact, the tiny cloud droplets do sink, but so slowly that it would take an hour for a single droplet to sink only one yard.

事实上，这个微小雾滴做沉没，但得很慢，它会花一个小时为一个单一的液滴下沉只有一个院子。
