摘　　要：比较了低能电弧放电电流线性衰减模型和动态伏安特性模型 .指出两者在反映最小建弧电压、放电瞬间的电流下降率和放电时间这 3个参数上是一致的 .但是对于反映放电能量的两个组成部分之间的比值这一参数上 ,前者的结论是该比值只与电源电压有关 ,而后者的结论是该比值与电源电压和电路电感都有关 .分析发现电流线性衰减模型是动态伏安特性模型的特例 。The current linear attenuation model and dynamic V A characteristics model were compared. The result shows that both of the models are coincided with each other in the following three parameters: minimum arcing voltage,current drop rate at the moment of discharge and discharge time. But for the ratio of arc discharge energy components, it is related to the source voltage based on the former model, and to both the source voltage and the circuit inductance based on the latter model. It can be concluded that the former model is a special case of the latter one, which can solve the problem mentioned above.
