摘要
地磁扰动与工伤事故之间的相关分析给出，工伤事故的平均发生率与磁情指数Ａｐ成正相关，当磁情指数大于３０时，相关系数达０．９３，磁情指数从３０变到２００时，事故平均发生率从０．７增大到１．８５。高磁扰日的平均事故发生率最高可达磁静日的２．６７倍。作为重要的环境因素的地磁场，当其变化超过人体的可调节范围时，人的机体和行为就要会到明显地干扰，从而导致各类工伤事故的大量增加。
Some significant conclusions can be got from the correlation analysisbetween industrial accidents and geomagnetic disturbance. Such as the frequency ofindustrial accidents is directly proportional (correlation)to the magnetic field index. Thecorrelation coefficient will be 0.93 when the index is more than 30. The frequency ofindustrial accidents will increase from 0.7 to 1.85 as the magnetic field index changesfrom 30 to 200,and the highest frequency in the day with intense magnetic disturbance is2; 67 times as much as that of general day. Geomagnetic field is an importantenvironmental factor. Persons organization and acts will be effected seriously by thechange of geomagnetic field when the change exceeds the range that one can adjust himselfto adapt t.。Thus industrial accident will increase obviously in the period.
