In many plasma applications, the plasma current, which is determined by the plasma density and drift velocity, is an important parameter when investigating the induced phenomenon and its effects. However, it is unclear which physical parameters are responsible for regulating the current. Plasma is generated by a balance between the driving and restricting forces. The driving force originates from the electric and magnetic fields, and the restricting force originates from collisions between different species (electrons, ions, and neutral particles). When the electric field fluctuates over time, the pressure of the driving force is generated. The pressure of the driving force depends on the square of the electric field and the reciprocal of the repetition frequency. The pressure of the restricting force depends on the gas flow velocity and the collision frequency. When electrons and/or ions flow with the flowing neutral gas, a plasma current is generated from flowing charged particles. The magnitude of the plasma current is linearly proportional to the pressure caused by the driving force, and the variation in the plasma current depends on the pressure caused by the restricting force. In addition, the plasma current varies with the applied period of the voltage. Consequently, the plasma charge, which is the time integral of the plasma current, shows a linear relationship with the driving force and is thus regulated by the force balance between the driving and restricting forces. Therefore, the plasma current value and its generation time are regulated by the strength, applied period, and repetition frequency of the applied voltage and the neutral gas flow velocity.

通过驱动力和限制力之间的平衡来调节等离子体电流

在许多等离子体应用中，由等离子体密度和漂移速度决定的等离子体电流是研究感应现象及其影响时的一个重要参数。然而，目前尚不清楚哪些物理参数负责调节电流。等离子体是由驱动力和限制力之间的平衡产生的。驱动力来自电场和磁场，限制力来自不同物种（电子、离子和中性粒子）之间的碰撞。当电场随时间波动时，就会产生驱动力的压力。驱动力的压力取决于电场的平方和重复频率的倒数。限制力的压力取决于气体流速和碰撞频率。当电子和/或离子与流动的中性气体一起流动时，流动的带电粒子会产生等离子体电流。等离子体电流的大小与驱动力产生的压力成线性比例，等离子体电流的变化取决于限制力产生的压力。此外，等离子体电流随着电压的施加周期而变化。因此，等离子体电荷是等离子体电流的时间积分，它与驱动力呈线性关系，因此受驱动力和限制力之间的力平衡调节。因此，等离子体电流值及其产生时间受强度、施加周期、
