| 摘 要： | 在三维热传导理论的基础上，研究药剂按零次阿累尼乌斯定律发生热分解时，所产生的热量对电火工品（EED）三维场分布的影响，采用时域有限差分法，获得了EED被点火时的温度场分布图。由温度场分布图可以认定，EED最初的点火点发生在桥丝与药剂的交界面上，计算结果显示：药剂随着活化能E的增加，电点火时间延长；随着频率因子Z的增大，电点火时间缩短。

| Abstract: | Based on the theory of 3 dimension heat transfer, the influence of heat created by priming decomposing according to the zeroth Arrhenius law on the temperature field in EED was researched. With the finite differential time domain method, the figures of ignition temperature field distribution in EED were obtained, and it showed the ignition point was happened on the interface between the bridgewrie and priming. With the numerical value calculation, the results show that ignition time is extended with E increased, and it is shorten with Z increased. |
