Pulsed electrical discharges in dielectric liquids are intensively studied due to the wide range of applications in which they are implicated. Despite the simplicity of the experimental manipulation of these discharges, the underlying fundamental physics is relatively complex. In this study, we use the electrical characteristics, voltage and current, of pulsed discharges in water (various applied voltage and pulse width conditions) to determine the equivalent electrical circuit of the plasma. Based on a Mayr-type model, the plasma resistance is time-dependent, but the inductance is not. Considering that plasma resistivity also depends on electron density and temperature (Spitzer formula), the temporal evolution of these two parameters was also determined.

确定相当于水中脉冲放电的电路：评估电子密度和温度的时间演化


由于涉及广泛的应用，介电液体中的脉冲放电得到了深入研究。尽管这些放电的实验操作很简单，但其基础物理却相对复杂。在这项研究中，我们利用水中脉冲放电的电气特性、电压和电流（各种施加电压和脉冲宽度条件）来确定等离子体的等效电路。基于迈尔型模型，等离子体电阻与时间相关，但电感则不然。考虑到等离子体电阻率还取决于电子密度和温度（斯皮策公式），这两个参数的时间演变也被确定。
