摘　　要：爆炸磁频率发生器是在螺旋磁累积发生器的基础上附加一小电容构成的。通过炸药爆炸使电感迅速减小,以此在螺线管中激发出强的振荡电流并在短时间内产生功率足够强的微波脉冲。基于等效电路理论,分析了该装置中电流的时间特性及产生微波脉冲的可能性。最后,分析了电流的频谱特性及其与电路参数的关系。Explosive magnetic frequency generators consist of a spiral magnatocumulative generator with a small capacitive load. The sharp reduction of the inductance of the solenoid, caused by dynamite explosion, stimulates a strong oscillatory electric current in such devices, results in a sufficient strong microwave pulse in a quite short time. The induced electric current in the devices is analyzed on the base of their equivalent circuit diagram, and the frequency spectra of the current is also discussed.
