气压场剧烈涨落与四川强震爆发的基本关系研究

本文以孕震系统在爆发前夕的外敏性及外力的非线性作用为物理基础，对大气扰动下的地震爆发问题进行了初步探讨，不仅归一化了四川省有关台站近３０年来的气压数据，而且还分地震带归纳建立了具有灾用价值的气压发震指标，这些自然共性的提示，既是对外力效应的认证，也丰富了短临地震预报的科学依据。

Basic Relationship Between Strenuous Rise-Drop Of Pressure Field And Eruption of Strong Earthquake In Sichuan

Taking the external sensitivity and nonlinear action of external force before eruption of seis-mogenic system as physics base,we tentatively explore the problem of earthquake eruption underatmospheric disturbance. We not only standardized the pres sure data about 30 years of the sta-tion in Sichuan province,but also concluded and setted up the pressure prediction index withpractical value according to every seismic belt. The natural common characteristics both give evi-dence of external force effect,and enrich the scientific basis of short-imminent earthquake predic- tion.
