摘要
针对日均值前兆数据序列 ,提出一种新的前兆信息提取方法 ,即斜率差信息法 .以唐山台水准为例 ,进行了全时域扫描的实例计算 ,并与已有的几种方法进行了比较和检验 .结果表明 ,该方法经优化后对提取日均值中的短期前兆信息十分有效 ,具有推广应用价值 .
A new method for precursory information extraction, i.e., slope-difference information method is proposed in the paper for the daily-mean-value precursory data sequence. Taking Tangshan station as an example, the calculation of full-time-domain leveling data is made, which is tested and compared with several other methods. The results indicate that the method is very effective for extracting short-term precursory information from the daily mean values after the optimization is made. Therefore, it is valuable for popularization and application.
