| 摘 要： | 通过对水氡体异常月频次序列的周期分析，指出水氡群体异常具有半年和３个月的周期特征，并且在强震前，整个波形发生畸变，各分波的振幅明显增大，随着地震的临近，从次要波至主要波的畸变也是逐步发生的。从而可判断该异常群体含有地震前兆的成分以及地震的临近。对地震的短临报有着积极的意义，对其它有关的研究工作亦可提供有益的参考。

| Abstract: | In this paper, based on the periodicity analysis of the monthly frequency sequence of water radon group anomaly, it is pointed that the group anomaly of water radon has the feature of half-year and three month periodicity, the whole wave form is distorted and the amplitude of the subwave increases obviously before strong earthquakes. Immediately before earthquakes, the wave changed gradualy from subwave to major wave. Thus it could be determined wherther or not the group anomaly contains earthquake procursors and the earthquake is comming. It not only has active significance for imminent earthquake prediction, but also can provide a useful reference for other related studies. |
