禁试条约中的地震事件筛选判据分析

Analysis for Seismic Events Screening Criterions in CTBT

全面禁止核试验条约于1996年9月24日在纽约联合国总部开放供签署。条约规定了一套严格的核查体系,利用分布在全球的地震、水声、次声和核素台站,对全球有可能发生的核爆炸试验进行监测。条约文本中给出了可疑事件筛选判据清单,其中可疑地震事件筛选判据有十一条。论文主要研究了条约中地震事件筛选判据的基本原理,并利用国际数据中心给出的事件筛选结果,对条约中地震事件筛选判据的应用情况进行了简要分析。

The U.N opened the Comprehensive Nuclear-Test-Ban Treaty for signature on 24 September of 1996 in New York.Verification regime was defined in the treaty to monitor compliance of the treaty by global stations of seismic,hydroacoustic,infrasonic and radionuclide.Events screening criterions were listed in the treaty,including eleven seismic events screening criterions.Basic theory of screening criterions for seismic events in CTBT are discussed,and statistic analysis for performances of some main criterions are also discussed using standard screenedevent bulletin of IDC.
