当水龙头的水冲击脸盆底面时，会在脸盆底面近似形成圆形无水区域。该无水区域的半径随着四周水位的升高而减小，最后近似为零，无水区域消失。根据实际测量数据，在一些假设和近似处理的条件下，通过建立数学物理模型，借助数学软件计算得到了无水区半径与时间和流量的二元函数关系以及无水区周围水位高度与时间和流量的二元函数关系。

When the water from a faucet strikes the bottom of a basin ,a circular area with almost no water can be observed .The radius of this area will become smaller and smaller with time goes on , and finally disappear .Based on some experimental results and some hypothesis ,a mathematical model was established to analyze this phenomenon .The time and water flow dependence of the radius of the no water area and the height of the surrounding water were obtained .
