我国每年因雷击引发的火灾要有数百起,通过对各地雷击观察点的实测统计结果分析认为,雷击频率与建筑物高度的平方成正比。因此,高层建筑遭受雷击的概率较大,雷击对高层建筑造成的火灾危险性也较为严重,高层建筑的防雷比一般建筑物显得更为重要。 ——编者 In our country, there are hundreds of fires caused by lightning strikes each year. According to the statistical analysis of the measured results of lightning strike observation points in various places, the lightning strike frequency is proportional to the square of the building height. Therefore, the high probability of lightning struck high-rise buildings, lightning stroke on the high-rise buildings caused by fire risk is also more serious, high-rise building lightning protection than the average building is even more important. --editor
