| Abstract: | Forming principle of light-ing and lightning disaster was described, and objects which easily struck by light-ning were introduced. There four injury systems of lightning to human,such as di-rect lightning stroke,contact voltage, flanking stroke and step voltage. Light-ning protection measures should be tak-en in advanced by full using of lightning warning signals. At last, defense mea-sures of lightning disaster were intro-duced from building lightning protection and human lightning protection.The pa-per had important implications for avoid-ing effectively and reducing the lightning disaster loss. |
