雨滴下落的速度取决于它的大小，因此也取决于它的形状。在这里，我们描述了不同的简单形状，模型下降在空气中。虽然毫米级的液滴保持球形，但由于表面张力的作用，大于毛细管长度的液滴会变平，就像固体上的固着液滴一样。空气穿透更大的球状体，这是观察到的不稳定。他们进来了。吃到爆裂，产生无数碎片。版权所有（C）EPLA，2007
The velocity of a falling raindrop depends on its size, and thus so does its shape. Here we describe the different simple shapes which model drops falling in air. While millimetric drops remain spherical, owing to the action of surface tension, drops larger than the capillary length get flattened, as sessile drops on solids. Air penetrates still larger globules, which are observed to be unstable. They in. ate till they burst, generating myriads of fragments. Copyright (C) EPLA, 2007
