Abstract: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.
