The plasma oscillationspectrum of electrical discharge channel is analyzed, and the eigenfrequency of metal crystal lattice vibration is discovered in the spectrum.
从理论上对单脉冲放电通道的等离子体振荡特性进行了分析，发现其振荡频谱包含了金属晶格振动的本征频率。

For example, the peak at 20 MHz in the spectrum is caused by the parasitic oscillation due to the output capacitance of the MOSFET and the leakage inductance of the transformer.
