| 摘 要： | 通过对北京昌平台Ｓａｃｋｓ体应变和气压、水位及抽水资料的综合对比分析，较系统地论述了抽水对体应变年变、月变和日变的干扰作用，并探讨了消除干扰的方法。结果表明，去掉干扰后的体应变曲线与１９８９年大同等地震存在一定的对应性。本文在研究体应变的同时，也研究了地下水位的变化，并比较了二者的异同。

| Abstract: | Based on the comprehensive comparison analysis of the Sacks body strain,atmosphericpressure,water level and pumping data at Changping station in Beijing, the disturbance ofpumping to body strain is systematically expounded and the method for eliminating the disturbance is discussed. The results show that the body strain curve after eliminating the disturbance was corresponding to the Datong earthquake in 1989. This paper studies not onlybody strain but also groundwater level change and compares their similarities and differences. |
