摘要
地震前震区上空的气温会有所升高，其原因是地热通过地壳的裂缝传递到地表的空气中．这里我们通过因子分析和残差分析，建立起了适于描述地震级别和温度异常之间关系的回归模型，并分析了该模型适用的范围，为预报地震震级提供了一条新的思路．
The temperature over earthquake area is rising before earthquake coming, because the interior heat of the earth passes into air through the breaks on the crust of the earth. By factor analysis and residual analysis, a regression model is proposed, which is suitable for expressing the relationship between the unusual temperature and the grade of seism, and offers a new way for predicting seismic grade.
