摘　　要：根据苏05井水位受降雨影响具有滞后"记忆"效应的特点,利用褶积滤波方法,对苏05井水位的雨荷效应进行处理和改正。处理结果表明,井水位与固体潮理论值的相关系数由处理前的0 241上升为改正后的0 651,达到未受降雨影响的水平,因此对于受降雨影响严重的井孔水位进行降雨量的改正是有效而又极其必要的。According to the lag 'memory' characteristic of Su No. 05 well affected by rainfall,the ground water level of Su No. 05 is corrected by the convolution filter method.The process results show that the correlation coefficient between the ground water level and the theory value of solid tide raises from 0.241 before processing to 0.651 corrected by rainfall,and the correlation coefficient reaches to the level that the water level has not affected by rainfall.So it is effectual and necessary to have a rainfall correction for the well which is affected seriously by rainfall.
