摘　　要：确定脉冲氙灯脉冲放电电阻和电流特性的关系,对于解决由储能器到脉冲氙灯之间的能量有效传输问题以及进行脉冲灯的计算是非常重要的,而且放电电阻和电路参数的匹配决定了放电的波形,进而也影响放电的功率、等离子体温度、辐射强度和光谱分布。在实验的基础上测试了不同口径、不同充气气压的高功率脉冲氙灯在不同放电条件下等离子体柱的电阻,探讨了放电过程中放电电阻的特性。It is very important to determine the relation of impedance and current characteristic of xenon flash lamp discharge which can solve the energy transferring from capacitors to xenon flash lamp and help to design the flash lamp. Moreover, whether impedance and circuit parameter match determines the duration time of discharge and further determines power,plasma of temperature, radiation intensity and spectra of discharge. The impedance of plasma of flash lamp in different discharge condition was determined and was researched.
