| 摘 要： | 用多项式拟合方法，分离出观测资料中的高频部分和低频部分，再用最小二乘法求出低频部分的直线方程。用VB编程：①检索出高频信号的超限时间、幅度、次数、超限率等；②计算出低频部分每日偏离直线均值。给定正常变化指标，从而逐项自动诊断，判定是否出现短临异常现象，为震情跟踪提供短临异常的快速识别处理软件。

| Abstract: | It is isolated from the high frequency part and low frequency part of the observation data by polyno- mial fitting method, and got the equation of the straight line of the low frequency part. And the results by the VB programming as following： （ 1 ） It can retrieve the high frequency signal of the overrun time, amplitude, frequency, overrun rate, etc. ; （2） It can calculate the low frequency part of the dairy average deviates from tile straight line. Given normal change index, the software can automatic check items and determine the short- term and impending anomalies for earthquake prediction. |
