闪电回击过程物理机制研究

Research on Physical Mechanism of Lightning Proeess

阐述了云地闪发生的物理过程 ,并根据国外一些类比实验对云地闪发生的物理机制进行了分析 ,主要就先导过程中电晕套的形成机制和回击过程中电晕套中空间电荷的中和机理做出解释。

The process of lightning leader and return stroke is presented according to some relative experiments on basis of physical mechanism.The cause about the formation of corona envelop and the mechanism how the space charge in the corona envelop is neutralized are mainly discussed.
