摘　　要：计算了飞机客舱后部形成4个110 mm×130 mm大小的创口时雷电直击耦合入飞机客舱内的概率。依据卫星观测的全国1995—2005年平均总闪电密度分布数据,计算得出在我国雷电密度最大的湛江地区飞行时,雷电直击耦合到4个创口的概率仅为180万亿分之一。The probability of lighting strike that couples to airplane cabin through four cuts was calculated,and each size of the cuts in the back of the airplane is 110×130 mm2.According to the distribution data of the nationwide average total lightning density by satellite observations from 1995 to 2005,it was calculated that the probability of lighting strike coupling to the four cuts is only about one of 180 trillions when the airplane flies in Zhanjiang region where the lightning density is the biggest in our country.It is not likely to take place in such a small probability.
