摘　　要：通过对电探针工作原理的分析,提出采用宽脉冲网络源代替传统窄脉冲网络源的技术措施,以解决时常遇到的“提前导通”问题。模拟计算和实验测量结果表明:尽管受到提前导通的影响,采用宽脉冲网络源的电探针信号仍然能够分辨出冲击波或飞片、自由面到达观测点的时间信息,从而给出真实可信的时间测量值。A measurement technique of electrical shorting pins based on broad pulse forming circuit is described here. The problem of pins shorting advance can be solved with this technique in place of the conventional narrow pulse forming circuit. The results of simulations and experiments show that the arrival time of shock-wave, flyer or free-surface can be determined precisely and reliably from the pins＇ signal with broad pulse forming circuit regardless of shorting advance somewhat.
