摘　　要：为提高观测数据的准确性,对姑咱台四分量钻孔应变观测进行了实地相对标定和实地绝对标定。在标定过程中,充分考虑了相位滞后对耦合系数反演的影响,通过反演计算得出相位滞后并将其消除,这样得出的耦合系数的准确性比没有考虑相位滞后得出的耦合系数的准确性有明显提高。In order to improve the accuracy of observations and make further research, the in-situ relative calibration and absolute calibration of the 4-component borehole strainmeter at Guza station were made. In these calibrations, the influence of phase lag on the coupling coefficients sufficiently was considered and eliminated, thus the accuracy of the coupling coefficients has been obviously improved after in-situ calibration.
