| 摘要: |
| 采用等效天线负载法计算了电磁环境下桥丝式电火工品中的辐射感应电流，结合具体算例模拟了核爆电磁脉冲和微波武器作用下桥丝中感应电流的热效应。研究结果表明，核爆电磁脉冲不易造成桥丝火工品的意外发火，但高功率微波武器的连续作用，会导致桥丝式电火工品在极短的时间内发火。 |

| Abstract: |
| The method of equivalent aerial and load was used to calculate the induced current in the bridge of bridge wire electric explosive device (EED) that caused by electromagnetic radiation. An example was used to simulate the heat effect of induced current at the interfaces between wire and powder of EED. Simulation result showed that the electromagnetic pulse of nuclear explosion usually does not cause explosion of EED, but the continuous action of high power microwave weapons can cause explosion of EED. |
