雷电是伴有闪电和雷鸣的一种雄伟壮观而又令人生畏的放电现象,产生雷电的条件是雷雨云中有积累并形成极性。雷电对人体的伤害,有电流的直接作用和超压或动力作用以及高温作用等。人遭受雷电袭击的瞬间,电流迅速通过人体,重者可导致心跳、呼吸停止,脑组织缺氧而死亡。另外,雷击时产生的火花,也会造成不同程度的皮肤烧灼伤。雷电击伤,还可使人体出现树枝状雷击纹,表皮剥脱,皮内出血,也可造成耳鼓膜或内 Lightning is a majestic and intimidating discharge accompanied by lightning and thunder. The condition for generating lightning is the accumulation and polarity of thunderstorm clouds. Thunder damage to the human body, a direct current and over-voltage or dynamic effects and high temperature effects. The moment of lightning attack, the current rapidly through the body, severe cases can lead to heartbeat, respiratory arrest, brain tissue hypoxia and death. In addition, the sparks generated when lightning strikes, can also cause varying degrees of burning of the skin. Lightning injury, but also make the body appear dendritic lightning striae, epidermal stripping, intracutaneous bleeding, can also cause eardrum or inner
