摘要
小波理论是近年来迅速发展起来的新兴学科，已成为众多领域的研究热点。本文介绍了连续小波变换和离散小波变换的构造及部分性质；分析了小波变换与Ｆｏｕｒｉｅｒ变换的关系；小波分析的特点与适用领域，给出了振动工程上的三个典型应用。
Wavelets is a developing subject. It provides a new toll employing digital signal processing in engineering. The purpose of this paper is (1) to introduce wavelet transform and its construction and partial characteristics, (2) to analyze the relation between wavelet transform and Fourier transform, (3) to point out the wavelet's features and practical fields, (4) to describe new results from the application of the wavelet transform to vibration analysis.
