摘　　要：研究了提取多参数无量纲中、短、临地震前兆信息的4种数学方法，以1976年7月28日唐山7．8级地震周围250km内11个计算点的地下水位、水氡、地电阻率、地应力、定点水准、连通管、倾斜仪、伸缩仪和气温等9种资料为基础，计算多参数无量纳地震前兆信息。应用特尔裴方法评价4种方法的相对重要性，以选择出最佳方法。After studying four mathematical methods of extracting the multiparamter non - dimensional precursor informaion of medium, short and impending earthquakes, based on the data of groundwater level,radon in groundwater, earth resistivity, crustal stress, fixed point leveling, connected pipe, clinometer,tensometer and air temperature from 1975 to 1977 at 11 computation points (stations), which were within the range of 250 km around epicenter of the M7. 8 Tangshan earthquake (1976. 7. 28 ), the multiparameter non - dimensional earthquake precursor information is calculated, and by use of Terfi's method the relative importance of four methods is evaluated so as to select the optimal scheme.
