摘要/Abstract

摘要： 讨论了分式滤波器小波的一个子类Rf_N小波,并从理论与应用两个方面将其与Db_N小波进行比较,得出Rf_N小波在理论与应用上均明显优于Db_N.应用方面的比较是通过分析哈尔滨地区从1881年到2000年的几项气象资料进行的.

关键词: 分式滤波器小波, Rf_N小波, 气温数值分析

Abstract: A subclass of rational filter wavelets-Rf_N wavelets has been considered,and compared with Db_N wavelets in theoretical and applied aspects.The conclusion that Rf_N wavelets is superior to Db_N wavelets in these two aspects is drawn.The comparison about applications is conducted by analyzing meteorological data of Harbin region from 1881 to 2000.

Key words: Rational filter wavelet, Rf_N wavelet, numerical analysis of temperature
