利用空间线性度方法，对前兆场中不同台站、不同学科的前兆观测数据从总体形态上进行综合分析，得到关于描述前兆场的新的特征量α（空间线性度）。本文给出了空间线性度的具体计算方法，并以华北地区为例，分析处理了区内１９７０～１９９４年部分地电阻率和地下水位观测资料。所得结果表明，新的前兆特征量α在中强地震之前一年左右时间内有异常显示
By using the method of spatial linearity, the precursory observation data of different stations and different disciplines in the precursor field are comprehensively analyzed from the overall morphology, and a new feature quantity α (spatial linearity) describing the precursor field is obtained. In this paper, the specific calculation method of spatial linearity is given. Taking North China as an example, the partial resistivity and groundwater level observation data from 1970 to 1994 are analyzed and processed. The results show that the new precursor eigenvalues α show anomalies within a year or so before the moderate-strong earthquakes
