| Abstract: | The rainfall response characteristic of observation data in Jinxian Xiao xinzhuang station is ana- lyzed. Then the non--tide data is preproeessed using normal anomaly method to eliminate the annual period, using K--L line curve fitting method to eliminate the line zero point drift. Finally, the preprocessed data is recomputed to eliminate rainfall interfere using the method of dynamic system. |
