The value of surface roughness is influenced by discharge current which involves discharge energy, pulse duration and polarityeffect.
在加工过程中，表面粗糙度会受到放电电流的影响，其中包括放电电流能量、电流脉宽及电流极性的影响。

The effect of electrostatic force of the drive voltage on the accelerometer had been researched when the bias voltage polarity is positive-negative configuration.
前人在研究驱动信号对传感器的静电力效应时，用偏置电压极性为正—负配置的驱动信号进行研究。
