摘　　要：从爆炸磁频率发生器的等效电路原理分析,研究电感的变化规律对发生器工作电流时间特性及频谱特性的影响及比较,结果表明:电感减小率以先快后慢的形式变化时,能提高发生器抗击穿的能力和工作频率,接着从实际模型出发,对有电枢存在时的电感计算进行修正,提高了发生器电感计算的精确度,最后,通过实验的方法验证了爆炸磁频率发生器产生脉冲辐射的可能性。From the equivalent circuit principle analysis on explosive magnetic frequency generator, the influence and comparison of inductance variation discipline on time and frequency characteristic of generator operation current is analyzed. Result shows when the inductance reduce rate changes from fast to slow, breakdown resistance of generator improves and operation frequency increases. Then from the actual model, the inductance calculation is amended for the presence of armature to improve the precision of the generator inductance calculation. At last, the possibility of the pulse radiation generated by explosive magnetic frequency generator is validated by experiment.
