| 摘 要： | 利用改进后的维纳滤波对青岛地电阻率资料进行了处理，排除了地下水位、温度、降雨和气压等因素对地电阻率的影响，提高了资料的可信度．处理后的地电阻率３个分向在黄海Ｍｓ５．３级地震前１１～１２天均出现了明显的短临异常，异常出现的时间也比较同步．

| Abstract: | After processing observation data of earth resistivity in Qingdao using improved Wienner filtering,the influences of groundwater level,temperature, rainfall and barometric pressure on the data have been removed, thus the credibility of data could be increased. The earth resistivity data processed as above in three direction had began to show short-term and impending anomalies obviously 11-12 days before the earthquake (Ms5.3) in Yellow Sea, and these anomalies appeared more synchronously |
