摘　　要：用加卸载理论对珲春7 0级深震前加卸载响应比群体异常随时空的变化进行了研究,结果表明响应比群体异常项次具有配套性,在时间上具有突变性,在空间上具有迁移性,是中期异常阶段向短期异常阶段过渡中的标志,是非线性系统失稳的过程。The changing characteristics of the group anomaly of the loading and unloading response ratio for the ground fluid befor Huichun Ms7.0 deep earthquake are studied aplying the loanding/unloading response ratio theory.The results show that the anomlay item number form a complete set,happen the sudden change at time,migrat at space.It is a mark of the transition from medium-term anomlay to short-term anomly andunstability process of nonlinear system.
