摘要
分析了蓟县小辛庄台形变观测资料的降雨响应特征,对观测数据的非潮汐部分分别用一般距平法去年周期、K-L直线拟合方法去线性零漂等处理,再用动态系统法[1]对预处理数据进行排除降雨干扰计算,取得了一定的效果。
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.
