| 摘 要： | 从溧阳台体应变分钟值曲线中．我们发现两起较明显的干扰现象。根据两起干扰的记录特征，我们对仪器、信号接线、仪器接地线和外部环境干扰逐步分析检查，发现其中一起是由交流电源干扰引起的，另一起是由仪器信号线接触不良导致的。针对不同原因，我们采取了相应的处理办法．有效排除了两起干扰源对体应变记录的干扰。

| Abstract: | From the minute-value curve of the body-strain at Linyang Station, we find two clearer interference. According to the record characters, we gradually looked up and analyzed the interference of instrument,signal connection, instrument grounding and outer-circumstances. We found that one was aroused by alternating current, the other was brought by the bad contact of signal connection. In terms of difference reasons, we effectively obviated two interference by taking relevant methods. |
