格值函数的建立及应变值计算模型的推导

THE ESTABLISHMENT OF CALIBRATION FUNCTION AND DERIVATION FOR STRAIN VALUE COMPUTATIONAL MODE

对ＹＲＹ－Ⅱ型钻孔应变仪的观测资料进行了较为深入的研究，并对河北省滦县地震台ＹＲＹ－Ⅱ型钻孔应变仪的４套观测数据均给出了格值函数，并给出了应变值计算模型的通用表达式，对钻孔应变仪非线性格值函数的研究有实际意义．

A further study has been taken on the observing data from Type YRY-Ⅱ boreholestrain meter. Some results are got and calibration functions of four sets of observing data from Type YRY- Ⅱ borehole strain meter at seismical station of Luan county,Hebei province were calculated out. Meanwhile,a common expression of computational mode for strain value was put forward,which would be of practical significance in the study of non-linear calibration functions of borehole strain meters.
