英文摘要：

The electrically exploding process of fuses used in high power pulsed source was analyzed. The non-expanding and expanding computational models were established separately based on the conservation equations of mass, momentum and energy. According to the established model, an output pulse of an accelerator＇s high power pulsed source was simulated by computer program. The results show that the theoretical results are better than the experimental results.
