We use a uniformly rotating dipole, which represent the inner freedom, to describe conformational changes.

用一个匀速转动的偶极子来描述马达的构象变化，考虑了马达的内部自由度。

Acoustic vector sensor with the electronic rotating directivity of dipole can effectively detect signal in the background of noises. More information can certainly be obtained by vector sensor array.

单矢量传感器具有可电子旋转的偶极子指向性，声压、振速信息联合矢量信号处理在噪声背景下有良好的探测能力，矢量(传感器)阵能取得更好的能力。
