| 1. | 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。 |
| 2. | 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。 |
| 3. | 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。 |
| 4. | The falling speed of cloud droplets is small and falling cloud droplets are not very effective in scavenging smaller particles .
云滴下落速度不大，下降的云滴对清除较小粒子并不十分有效。 |
| 5. | 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。 |
| 6. | Cloud - drop sampler
云滴取校器 |
| 7. | A rotating column of air ( made visible by cloud droplets ) that does not touch the water surface is called a funnel cloud
如果该旋转云柱(由于云滴的存在而变得明显)没有到达水面，就叫漏斗云。 |
| 8. | 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。 |
| 9. | 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。 |
| 10. | These ions are thought to help create new particles called aerosols and , when aerosols grow above a certain size , they become the seeds around which cloud droplets form
人们认为这些离子有助于产生被称作气溶胶的各种新微粒，而且当气溶胶的体积增大到一定规模，它便成了云滴形成的“温床” 。 |
