Abstract

Abstract: A series of fractal and Liesegang Ring precipitations were obtained in metal-deoxycholate acid sol-gel system, refereed to the environment condition of the human beings' gallstone growth. the gallstone growth process was studied theoretically and quantitatively With computer pattern treatment and theoretical calculation of fractal dimensions.

Key words: deoxycholate acid, Leisegang Rings, fractal, fractal dimensions

摘要： 结合胆结石生成的体内环境，在金属-脱氧胆酸凝胶体系中得到了各种金属离子与脱氧胆酸结合生成的分形和Liesegang Rings沉淀。经过图象处理，测量了各种分形图案的分维数，从而通过计算对胆结石的形成过程予以一些定量的探讨。

关键词: 脱氧胆酸, LiesegangRings, 分形, 分维数
