| 摘 要： | 泰安台压容差应变仪１９９１年投入观测以来，为确保资料正常、连续，对井上仪器，探头引线及井下探头３个环节的干扰因素进行了排除工作。整点值资料已连续４年，缺数不超过４８小时，采用多种方法判定异常，发现改进的多道维纳滤波方法处理的资料，对４００ｋｍ范围内的中旨地震有明显的异常显示。

| Abstract: | The pressure solution differential stress at Taian Station was begun to be observed in 1991. In order to ensure the observed data to be normal and continuous,the interfernce factors of the instrument on the hole, the sensor leg and the downhole sensor have been eliminated, the hour data have been continuous for 4 years, the missing data are no more than 48 hours. By using many kinds of methods to identify anomalies, it is found that the data processed by the improved mutichannel Wienner filtering method showed obvious anomalies to the moderately strong earthquakes within the range of 400 km. |
