摘要
小波分析是应用数学的一门分支,在各个领域都有着广泛的运用.对小波变换的方法步骤进行了阐述,并以成都市建国以来粮食产量年际变化为实例,进行了分析实践.实例表明,小波分析的成果能够很好地为区域粮食政策服务.
As a branch of applied mathematical, wavelet has been used widely in many domains. In this paper, the steps of wavelet transform were depicted. Additionally, practice has been done with the date of yearly gain output change in Cheng Du during 1950 to 2005. Practice reveals that the fruits of wavelet could serve the policy of gain reasonably.
