雷电俗称闪电,是大气中强烈的超长距离放电过程,通常伴随着强对流天气过程而发生,是一种常见的自然现象。通常,雷电电压可达几万伏至几百万伏,瞬间电流可达几十万安,被雷击的物体会燃烧。人体若被雷电击中,可致心脏和神经麻痹,心脏停止跳动,也可致脑神经受损,抑制心跳和呼吸中枢,几分钟内就可致死。
Lightning, commonly known as lightning, is an intense over-long-distance discharge process in the atmosphere and is commonly accompanied by strong convective weather processes, a common natural phenomenon. Typically, lightning voltage up to tens of thousands of volts to millions of volts, the instantaneous current up to hundreds of thousands of safety, the object will be struck by lightning. If the body is struck by lightning, can cause heart and nerve paralysis, the heart stops beating, can also cause brain damage, inhibition of heart and respiratory center, can be lethal within a few minutes.
