【摘要】 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。更多还原

【Abstract】 he non-steady model and the characters of amplitude and frequency of non-tidal deformations are discussed through liner and nonliner, stable and unstable, determined and stochastic processes. By using F -detection and dynamics, the composition, quantity and criterion of anomalies are studied.It is demonstrated that the qantited concept of “anomaly” involves the amplitude and frequency information of observed deformations, and larger earthquake or earthquake cluster may correspond with the anomaly in majority.更多还原
