INSTRUMENT SITE CALIBRATION CAN NOT BE REPLACED BY DATA PROCESSING
对四分量钻孔应变观测的实地相对标定、绝对标定问题的分析得出:通过“四分量自检”的数据处理,仅能得到3条测线元件的实地格值分别与作为常数项的测线元件的实地格值的比值,不能得到实地标定格值,无法解决四分量应变观测的实地相对标定.“加衬模型”利用理论固体潮与分量应变观测值之间的关系可以计算得到耦合系数,但并不能对弹性参数进行标定,无法解决分量应变的绝对标定问题.
The paper analyzed the relative calibration and absolute calibration of four component borehole strain observation.By the theorem "sum of vertical components must be equal",we can only obtain the ratio of site scale value of 3 sensors and the sensor which is as a constant element,but we cannot get site scale value,so it cannot solve relative calibration.By the relationship between tides and component strain observation value,the coupling coefficient can be c…查看全部>>
