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.

水滴像任何弹性体一样， 受到适当的外力，而由此产生的 振荡本质上是有趣的，它们可能是 了解各种方法的优点和局限性至关重要， 使用微波的遥感装置，包括各种 气象雷达这项工作，虽然主要是实验性的， 在现有理论的指导下，将试图研究 水滴（直径0.8至5 mm）在一个 合理的现实，虽然受控的环境和确定 观察到的形状的原因。
