| 摘 要： | 本文利用两种资料处理方法,分别算出帕金森矢量系数 a,b 及转换函数的同相部份 Ar,Br 和正交相部份 Ai,Bi 两种处理方法的结果是相近的.上述六种参量都很小,表明菏泽地区的电性结构相当均匀.两种结果似乎都出现了异常变化,在菏泽地震前后上述参量的数值减小.

| Abstract: | In this paper, the coefficients Parkinson vector a, b and the in-phase part Ar, Br and quadrature-phase part A1, B1 of transfer functions are calculated by using two kinds of data processing methods, respectively. The results of both methods are close to each other. All the six parameters mentioned above are low in value, showing that the electric structure in the Heze area is rather uniform. It seems that anomalous changes appear in both results, and the values of parameters decrease before and after the Heze earthquake. |
