摘要
本文介绍了分形和分维的概念及计算分维的几种方法,并用离散时间序列计算分维的方法计算了天气温度和振动信号的分维数,为信号分析提供了一种有应用前景的新的分析方法。
This paper introduces the concepts of fractal and fractional dimensions, and offers some methods for calculating fractional dimensions. By means of calculating the fractional dimensions of time eeries, thote of the atmopheric temperature and vibration signals are obtained, thus providing a perspective method for signal analysis.
