本文的目的是对任何时刻 t 建立下一次我国大陆大震发生的时间、地点的预报公式.首先,我们给出 t 后三个月内我国大陆是否有大震的判别.若有,再进一步确定时间、地点.为此,利用了全球大震与我国大陆大震在时间、地点上的联系,并运用随机过程的理论,导出了所需的公式. The purpose of this paper is to establish a prediction formula for the time and place of the next major earthquake in mainland China at any time t.First, we give a judgment of whether there is a major earthquake in mainland China within three months after t, and if so, further determine Time and place.Therefore, we make use of the relation between the earthquakes in the world and the earthquakes in our country in time and place, and use the theory of stochastic process to derive the necessary formula.
