摘　　要：根据钻孔四分量应变观测特点,分析了评价该观测手段的质量指标:相对标定自检内精度。介绍了相对标定自检内精度方法以及存在的问题。通过对比分析平均值、相关系数等,提出不同的求偏差方法,改进了相对标定自检内精度法,使其能尽量客观地评价观测质量。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 observation can be evaluated.
