Studies of Raindrop Oscillations

与任何弹性物体一样，水滴在受到适当的外力时会发生振荡，虽然由此产生的振荡本质上是有趣的，但它们对于理解使用微波的各种遥感设备的优点和局限性可能是必不可少的，包括各种气象雷达。这项工作虽然主要是实验性的，但受到现有理论的指导，将试图在一个合理现实但可控的环境中检查水滴(直径0.8至5毫米)的振荡，并确定观察到的形状的原因。

A water drop, like any elastic body, will oscillate when subjected to a suitable external force, while the resulting oscillations are intrinsically interesting, they could be essential to understanding the merit and limitations of various remote sensing devices employing microwaves, including various meteorological radars. The work, largely experimental though guided by existing theory, will attempt to examine the oscillations of water drops (0.8 to 5 mm diameter) in a reasonably realistic though controlled environment and determine the causes of the observed shapes.
