人工尖端放电形成的空间电荷层既不足以阻止先导的继续推进，也不能防止产生上行先导。

The space charge layer formed during point discharge process is not enough to prevent the leader from marching, and can not prevent the forming of upward leader, either.

静电具有高电压、静电感应及尖端放电的特点，放电产生的静电火花容易导致爆炸和火灾事故。

With high voltage, electrostatic electrostatic induction and point discharge, discharge the characteristics of the spark generated is easy to cause the explosion and fire accident.
