摘要
本文综合运用文献[1]～[4]的理论与计算方法,对邢台等四个地应力观测站1982～1988年间连续观测结果的特征进行了研究分析,将近期观测结果与1974～1984年的结果相比较,发现附加应力参数动态基线的系统变、偶然变,动态比例因子、比率变化、带权相关系数等各种具有前兆特征的变化,可能是与华北地区地震的孕育或发生有关的应力异常信息。
This paper, by theory and calculatnig method in References [1] [4] analyzes the characteristics of the continuous observation results at four earth stress stations of Xingtai and others in the period of 1982-1988. It is found that, compared with the results of 1974-1984, the recent results show various variations with precursorycharaeteristics, such as the systematic variation, accidental variation, dynamic proportional factor variation, ratio variation and weighted corresponding coefficient of the dynamie base line of additional stress parameters. These variations may be the information of stress anomaly associated wfth earthquake preparation an occurrence in North china area.
