【摘要】 地震前兆涉及到众多物理的和化学的观测方法,且计量单位也各不相同,因此,在各类前兆异常之间无法进行直接的定量对比,从而给地震综合预报标志体系的建立带来了困难。针对这一技术难题,本文提出了对各类前兆观测项目都适用的一个无量纲值(异常从属函数值μ)来统一归划不同性质、不同计量单位的地震前兆异常,并由此建立起具有重现性的地震前兆短临综合预报指标,还给出了各类地震前兆映震能力的定量描述。更多还原

【Abstract】 The earthquake precursors are related to various physical and chemical observational techniques,and their metric units are also different. Therefore, the direct quantitative comparation among various precursory anomalies is impossible, which brings difficulty to establish the index system of comprehensive earthquake prediction. Aimed at this technical difficulty,the authors proposed a non-dimensional value (anomaly subordinate level μ), which normalized different property and metric units of precursory; thus to establish the comprehensive prediction index of the short-term and impending earthquake precursors as well as give the quantitative describtion of capacity to reflect earthquakes of various earthquake precursors.更多还原
