| 摘 要： | 利用传导方法研究射频对桥丝式电火工品的桥丝电阻、烤爆、迟发火以及瞎火等性能影响。研究结果表明，在10％发火功率和0．4MHz的敏感频率条件下，所研究的3种电火工品在照射1～5min后，电阻增加1.2％～7．4％，并且17．3％的试样在照射的过程中出现了烤爆；在对经过照射后的试样进行正常的发火感度试验中，发火时间显著增加，出现了不同程度的迟发火，16．9％的试样瞎火。

| Abstract: | The influence of radiofrequency on the electric resistance, cook-off,delayed fire and misfire for hot-bridge electric explosive device was studied by conduction method. The electric resistance of hot-bridge increases 1.2%-7.4% after irradiation for 1min-5min,and 17.3% samples are cook-off during irradiation. The fire time of samples after irratiation increases notably,and 16. 9 % samples are misfire during the normal fire sensitivity test. |
