摘要
利用最大熵谱方法，对我省及邻区几个井孔的地下水动态多年观测资料进行了熵谱分析。结果显示，地下水动态变化除了1年及1年以内的短周期成分外，还存在着3年和10年左右的卓越周期成分。对这一周期结构的认识，有助于正确识别地震的中短期异常信息。
In this paper,using the largest entrpy spectrum method,the entropy spectrum analysis is made for the obserational data of groundwater dynamic state of many years in several wells in Hebei Province and its neighbouring area. The result shows that the variation of groundwater dynamic state,besides one year and less than one year short period component,showed about three years and ten years predominent period component.This understanding on the period structure can help to correctly recognize the midterm seismic anomalious information.
