摘要
为了实现中国地震局“九五”重点攻关项目“中短期前兆识别方法、标识体系和评价研究”提出的目标,对北天山重点监视区1980~1997年的水化学观测资料进行了全时域的扫描分析,用差分求和法对资料异常进行了识别.结果表明:美分求和法能有效识别异常和提取地震中短期前兆指标.用该方法检出的异常判定指标信度较高。
The recognition method, index system and evaluation research of medium-,short-termprecursor"is a ma jor project of CSB in the ninth five-year plan. In order to attain the goal putforward by it, the 198O ~ l997 hydrochemical observational data of North Tianshan focalmonitoring area are made a scanning analysis in total time domain, and the anomalies con-tained in the data are recognized by using difference accumulation method. The result showsthat difference accumulation method can recognize anomalies effectively and extract medi-um-,short-term precursor indexes, and that the extracted indexes have higher credibility.
