| 摘 要： | 通过对“十五”水位动态干扰调查和分类总结，得到一类受周期性干扰的水位动态曲线。通过对该类动态的水位序列进行小波分解，得到其水位时间序列的不同分解层次的干扰特征；利用小波重构剔除干扰信息，得到水位动态的重构时间序列；通过对多个台站的水位序列进行小波分析，得到该类干扰的典型动态特征。

| Abstract: | A dynamic condition of water level which presents a cyclical varying has been found through the investigation and research to the digital water level data recorded during ＂the tenth-five year plan＂. Using the wavelet decomposition and the wavelet transform method to the data of water level, we can reveal the characteristic and composition in different levels.the data of water level, we can reveal the characteristic and composition in different levels. After that, through the wavelet reconstruction, we got the water level curves which the periodic interference has been filtered. Then, we re-decompos the water level data that has been reconstructioned and get the information of solid tide which is carried by the water level data. At last, we carried the comparative analysis of the water level data from different stations and then we got the typical dynamic characteristic of the interference and the way to identify it. |
