根据过程的线性与非线性、平稳与非平稳、确定与随机等特征，讨论了非潮汐变形的非稳态模型和异常的幅度与频度特征，运用Ｆ检验和动态场分析系统理论，对异常的合成、定量化及识别准则进行了研究。所提出的新的“异常”概念包含了动态过程的幅度和频度信息。结果表明，异常出现后，在一定区域范围和时间段，绝大多数情况下伴有地震或震群发生。
According to the characteristics of linear and nonlinear processes, such as linearity and nonlinearity, stationary and non-stationary, deterministic and stochastic characteristics, the non-tidal model and the amplitude and frequency characteristics of non-tidal deformation are discussed. By using F-test and dynamic field analysis system theory, The synthesis, quantification and identification criteria were studied. The new concept of “anomaly” includes information on the magnitude and frequency of dynamic processes. The results show that after the occurrence of anomalies, earthquakes or swarms occur in the vast majority of cases within a certain area and period of time.
