摘要
利用高台地震台不同时间尺度的钻孔四分量应变观测数据计算元件相对校正系数、自检内精度和面应变相关系数。分析认为,对较长时间尺度观测数据进行质量评价、应变换算和地震研究时,相对标定处理应选用连续观测的日均值或5日均值数据;对较短时间尺度观测数据进行以上分析时,相对标定处理应选用整时值数据。
Using observation data of different time scales from Gaotai station's 4-component borehole strain,we calculate the relative calibration coefficient,the self-test accuracy and the correlation coefficient of plane strain.Through the analysis,we derive the following conclusions:for long term scale observation data quality evaluation,conversion of strain and earthquake research,relative calibration processing should choose five daily average or the daily average of continuous observation data;for shorter term scale observation data quality,the relative calibration data processing should choose the duration.
