电火花声源的某些特性

Some properties of the spark sound source

文中给出了电火花声源的压力波形及其频谱图,着重讨论了储能与压力波峰值P1m、和半峰 值之间P1m/2的时间t1之间的关系,以及刚性圆筒内放电时边界对P1m和t1的影响。

The pressure waveform and its frequency spectrum of the spark sound source are given in this paper. The relation between the stored energy and the waveforms' peak values P1m, the time t1 of P1m/2 width as well as the effect of the rigid boundary on P1m and t1 are discussed.
