摘要
首先，我们利用现代非线性物理理论及震源理论建立了适合地震活动的逾渗模型。然后，我们利用这一模型，对辽宁地区1970 年以来的地震活动进行了研究。通过对地震活动的逾渗相变过程中逾渗阈值附近的各种临界指数的计算，对破裂概率达到或超过逾渗阈值的子区域进行了讨论并对近期辽宁地区的地震活动趋势进行了探讨。
First the percolation model of seismicity has been set up by the model nonlinear physical and seismic source theory. By using of this model, the seismicity since 1970 of Liaoning area is researched. The sub-area where the rupture probability reached or exceeded the percolation threshold and the shore-term seismicity of Liaoning area is discussed by calculating critical exponents of near by percolation threshold neighbouring in the percolation phase transition of seismicity
