摘　　要：静电放电发生时,由于气体压强、空气湿度、电极表面状况、环境温度等因素的影响,相关放电参数(击穿电压、电流、电场、磁场、峰值、弧长、上升斜率等)具有低重复特性。我们通过相关放电参数的处理来研究带电体和受电体之间间隙的电性质。从理论上和实验上深入研究放电间隙电性质的低重复特性,对于充分认识和把握静电放电的本质,对于静电放电危害的防护,有十分重要的理论意义和实际意义。通过改变静电放电发生器实验环境温度来获得相应的固定间隙放电情况下电流峰值的差异。试图从理论上对静电放电条件下所获得电流峰值的低重复特性加以初步的分析讨论。It pose nonlinear and discrete property for electric characteristics of electrostatic discharge gap that the related discharge parameter of break down voltage, current, electric field, magnetic field, peak value, arc length, rise slope, because of gas pressure, air humidity, electrode surface condition, ambient temperature. Deep theoretical and experiment research on nonlinear and discrete property of electrostatic discharge gap, facilitate much better to understand essential features of electrostatic discharge, facilitate to protection of threat and harm from electrostatic discharge. Measurements of discharge current are performed with electrostatic discharge generator for different situations of ESD with different ambient temperature. Difference of peak current is observed, and some analysis is provided on the difference. Parameters discrete property of ESD in air gap result in difficulty of making test standard of corresponding ESD in air gap.
