A tentative analysis of the mechanism of mantle circulation flow, continent drifting and earthquake origin is first clearly made, giving a simple mechanics-based explanation of the nature.

首先对地幔对流、大陆漂移和地震起源的机制做了尝试性分析，给出一个简单的力学解释。

We want to find the location, depth and origin time of an earthquake whose waves arrive at The Times measured on each seismograms.

我们想通过地震仪记录地震波经过的时间，确定震源的地点、深度和发生时间。

Using cumulative probability to estimate the possible stage of earthquake occurrence can fulfill the origin time of Markov chain.

用累积概率表示发震的可能程度可作为马氏链预测发震时间的补充；
