摘要
对1983~1995年兰州五泉山泉水溶气N2的观测值进行了数学处理,发现该组分在祁连山构造带东段几次中强地震前均有前兆异常显示.同时还对异常机理进行了初步探讨
Observation data of gas N 2 dissolved in spring water in Wuquanshan from 1983 to 1995 were processed mathematically.It is found that the gas had anomaly before several moderate strong earthquakes along the east segment of the Mt.Qilian structure zone.In this paper,the mechanism of the anomaly is discussed preliminarily.
