摘　　要：介绍了分形的基本概念和分形盒维算法.提出了一种新的太赫兹光谱识别方法.实验中测得了两种中药的太赫兹光谱,算出了它们的盒维数并进行了比较.通过这种方法使不同的药品得到了很好的鉴别.The basic concepts of fractal geometry and fractal box counting dimension are introduced. A new method of recognition of terahertz spectrum is suggested based on these concepts. The terahertz spectrums of two Chinese traditional medicines are obtained and their box counting dimensions are given and compared. The different medicines can be identified well in this way.

关 键 词：光谱学 分形 盒维数 太赫兹光谱识别
