摘　　要：探讨了一种以应变、倾斜为响应的加卸载响应比的计算方法，并对大同两次中强地震前华北北部地区的应变、倾斜加卸载响应比进行了计算，结果显示，此方法对预报地震有一定的可行性。In this paper, a calculational method of the Ioading and unloading response ratio of strain and tilt has been studied, and the loading and unloading response ratio of strain and tilt before Datong two mod erately strong earthquakes in northern part of North China area has been calculated. The result shows that this method has a certain feasibility for earthquake prediction.
