摘要
本文选定日均值的一阶差分值作为基本统计量,对我区七个定点形变连续观测台站的倾斜资料进行频数统计分析,并按Pd(≤r)=95%(d为日差绝对值)求得七个台站倾斜仪的正常复现域r值。在此基础上得到了各台辨别异常限值,作为初步区分正常与异常的依据。由举出的多个震例表明,我区地倾斜观测资料有分辨10^(-6)—10^(-7)异常的能力。
In this paper the author has chosen the first order differences of the dayly means of ground tilt observations for seven stations in Xinjiang as basic statistical data,then statistically analysed their frequencies.Finally we have obtained the normal change ranges r and the detectability of anormal change for these seven stations.Many examples presented in this paper shown that the ground tilt stations in Xinjiang can generally detect anormal changes of ground deformation over 10^(-6)-10^(-7)order of magnitude.
