| Abstract: | According to the characteristic of 4-component borehole strain observations,we analyzed the quality indicators about this observation:the self-test accuracy of the relative calibration.We described the self-test accuracy of the relative calibration and the problems about this method.By analyzing the mean,correlation coefficient,we have proposed different methods of the deviation calculated thus it improved the method of the self-test accuracy,so as far as possible objective assessment of quality of the obse... |
