处理了聊古一井1981 ～1984 年氦的观测资料,发现在两次较近的地震(1981 年宁晋MS5 .8 和1983 年菏泽MS5 .9) 前,氦都有明显的形态相似的异常变化.
The observed helium content data in Liaogu 1 well from 1981 to 1984 have been processed.It has been found that the data of helium content have a clear abnormal change and their anomaly forms are very alike before two near earthquakes (Ningjin M S5.8 in 1981 and Heze M S5.9 in 1983).
