摘　　要：对中国大陆已发生的多次7级以上强震震中区气温、气压资料进行了研究，结果表明：在大震前（30天之内），气温－气压函数的平衡状态被破坏，其相关系数（代数值）不断增大，“正弓”形可作为短临异常的标志，同时对其成因也进行了初步探讨。The authors have studied air temperature --pressure in the epicentres of strong earthquakes with Ms 7 in China mainland,and the results show that the balance of air temperature -pressure function was broken,and its correlation coefficient was increased,the curve of 'positive 弓' shape was looked as the sign of short--impending precursor. The authors have also discussed its genesis.

关 键 词：温度 压力 相关系数
