用高速摄影机拍摄火花塞点火的火花出现的瞬间为参考点,可以确定脉冲等离子体推力器放电电流波形与放电过程中所摄照片时间上的对应关系。这对于用高速摄影方法研究推力器放电过程是非常重要的。
With the high-speed camera shooting spark plug ignition spark appears moment as a reference point, you can determine the pulsed plasma thruster discharge current waveform and discharge during the photo taken on the time correspondence. This is very important for studying the thruster discharge process with high-speed photography method.
