As the relative velocity between the two layers is increased, waves are formed at the interface.
当两层流体之间的相对流速增加时，分界面成为波浪型。

The apparatus consists of a single board microcomputer, propeller type velocity sensor, tail fin type flow direction sensor and corresponding interface circuits and software.
该仪器以单极微机为核心，配置旋浆流速传感器、尾舵式流向传感器、相应的接口电路和软件。
