摘要
本文概略地给出了对钻孔应变仪原始观测资料进行处理的一套方法,并以河北省滦县地震台钻孔应变资料为例对每一步骤的中间数据均进行了应变固体潮调和分析的计算,从而验证每一个步骤的有效性,并最终得到了较好的调和分析结果。这一套数据处理方法的优点在于能更充分地利用全部观测资料,将非线性格值改正、频段频谱分析、气压相关分析及相关改正连成了一个整体,使该方法具有连续性、系统性和普适性。
In this paper, a set of methods is outlined for processing original data recorded by Bore-hole strainmeter. As an example, the data observed at Luanxian Station, Hebei province, have been processed and the tidal analysis has been made in different steps. It has been proved that all the steps are effective,and, the final results of tidal analysis are better than that in other steps. The advantages of the methods have showed that the observational data can be fully utilized, and that the correction of nonlinear vari-able grid-vale, the frequency spectrum analysis in different bands, the correlation analysis of atmo-spheric pressure and its correction are linked together as a whole procedure which has continuity, sys-tematicness and universality.
