| 摘 要： | 采用对比性试验，研究了接地电阻对火花放电击中点的影响．试验结果和观测均表明，接地电阻能抑制从接地端产生的迎面放电的发展速度和通道强度，从而使其被击中概率下降，负极性比正极性下接地电阻对火花放电击中点的影响要显著得多．

| Abstract: | The effect of ground resistance on discharge striking points has been studied by the contrast experiments. The phenomena and results show that the ground resistance can restrain the velocity and the strength of upward discharge, which will reduce the striking probability. The effect of ground resistance with negative polarity on discharge striking point is more sensitive than with positive polarity. |

| Keywords: | discharge striking point ground resistance positive polarity negative polarity |
