摘　　要：简要分析了射频能量对电火工品的危害机制,建立了电火工品发火电路的等效天线模型,推导出了电火工品处于最大拾波方向且阻抗匹配的情况下桥丝接收的最大射频功率数学公式,分析了外界电磁场场强和波长变化对桥丝最大接收功率的影响。The damage mechanism of radio frequency to EED was analyzed. An equivalent antenna model of electric ignition circuit of EED was established. The mathematical formula of the maximum radio frequency power received by load was deduced when antenna orientation and impedance were optimum. The influence of electronic field intensity and wavelength changing on the maximum power received was analyzed.
