对ＢｕｒｉｄｇｅＫｎｏｐｏｆ模型作了非线性化与非均匀化两项重要修正，并利用四阶ＲｕｎｇｅＫｕｔａ法对地震前兆场的演化过程进行数值模拟，得到与实例相似的结果。
The Buridge-Knopof model is modified by two important non-linear and inhomogeneous methods. The fourth-order Runge-Kutta method is used to simulate the evolution of the earthquake precursory field. Similar results are obtained.
