| 摘 要： | 北京五里营井水温每天都有24次锯齿状畸变,有很好的规律性,经分析认为是气氡观测对水温造成影响.将气氡和水温供电分离,并在水温地线和地网之间增加一个电感,以阻挡其他干扰信号由地线反馈到观测仪器,改造后水温脉冲干扰彻底消除,观测质量明显提高.

| Abstract: | We found the minute-value observing curve of the water temperature at Wuliying station in Beijing showed 24 sawtooth figures ordinarily,and confirmed that was caused by the radon observation.We separated the radon and the electric supply for the water temperature and added an inductor between the earth wire and earth mat to cut the other jamping signals from the earth wire to the observing instrument.After the transformation,the pulse jamping of the water temperature disappeared completly and the observing quality made much improvement. |
