【摘要】 采用“水位调和分析(M2波计算)”程序,对天津张道口地震台张道口-1井模拟、数字化水位内在质量变化进行了对比研究。从高频干扰、周围井孔的地下水开采、仪器零漂、探头位置与观测精度变化的关系、仪器自身原因5个方面分析了影响张道口-1井数字化水位内在质量的因素,并提出了数字化水位在日常观测中的注意事项。更多还原

【Abstract】 With the program of "the water level harmonic analysis(M2 wave computation)",we contrasted and analyzed the intrinsic quality change of the simulative and digital water level of Zhangdaokou-1 well in Tianjin seismic station.Based on 5 aspects of the high frequency interference,the under ground water mining of the bore-hole around it,null shift of the instrument,the relations of the probe position and the observation precision change,the instrument,we analyzed the intrinsic quality factors of digital water level affecting Zhangdaokou-1 well, and put up with the notice item of the digital water level in the daily observation.更多还原
