| 摘 要： | 利用谐波振幅和峰谷值2种方法，计算江苏地电台站渗流方位角，并尝试利用渗流方位角进行映震分析，结果表明：①使用2种方法计算的渗流方位角相差不大，由此所得地震对应关系应基本可靠；②高邮地电台渗流方位角与高邮-宝应MS 4.9地震对应关系较好。因此，对江苏地区开展渗流方位角变化特征分析具有一定意义。

| Abstract: | Two methods, harmonic amplitude and peak-valley value, are used to calculate the seepage azimuth of Jiangsu stations. Then the results are compared and analyzed. Finally, we study the response of the seepage azimuth to the earthquakes before. The result shows that:①The difference is very small between the seepage azimuth calculated by the peak-valley value method and the harmonic amplitude method. Therefore, it is reliable to try to carry out the seismic stress relationship with this result. ②The relationship between the seepage azimuth of Gaoyou station and the Gaoyou-Baoying MS 4.9 earthquake is very good. Therefore, it is of certain significance to carry out the research on the characteristics of seepage azimuth in Jiangsu area. |
