These anemometers, which employ hotwires, sonics, drag spheres, etc, are not commonly used because of operational and other difficulties.
这些风速计是使用热阻丝,声振、阻力球等来进行的,由于运用及其他方面的困难,所以不能普通地使用。

The sensibility of gyroscope was improved by using two vertical hotwires to sense two-dimensional angular velocity and simply-supported edges to support piezoelectric pump vibrator.
采用双垂直热电阻丝,敏感二维角速度; 通过简支边支撑压电泵振子,提高了陀螺的灵敏度;
