| Abstract: | 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. |
