摘要
本文对360例煤矿工人老年前期和老年期α频率慢化的研究，并与对照组365例干部比较，结果：若以9Hz以下的α波定为慢化，矿工组60岁～69岁慢化α频率为14．23％，干部为1．78％，两组差异有显著。矿工组55岁出现α波慢化，干部组则无1例出现慢化现象。说明煤矿工人在井下作业是一个特殊环境区，矿工衰老比较早而出现α频率慢化。
The article has been studied X-frequence chronic of 360 cases coalmine in the before old age and the aged, It was compared with collate group of 365 cardres, the results were that X-frequence chronic group in 60-69 old was 14.23%,that of cardres was 1.78%,two groups had remarkable difference. There were 55 cases to have X-rate chronic in coalmine, there was no in cardres, there was no in cardres, It was related that the coalmine were old more early and X-frequence chronic.
