粘土颗粒的分形特征及分维数的测定方法

The testing method of fractal feature and fractal mension of shale particle

粘土颗粒具有分形特征。分维数是一定类型的粘土矿物颗粒在一定环境中颗粒几何性质衣几何形貌的定量反映,可用于表征颗粒的分散和聚集方式及其机理。综述了粘土颗粒的分形研究,介绍了三种分维数的实验测定方法,即吸附法、SAXS(小角度X射线散射)法和NMR(核磁共振)法,并讨论了各方法的分辨率及各自的特点。

Shale particle with fractal feature . Fractal mension is a qualitative way of certain typical shale particle in certain condition of geometry character or geometry appearance helped to show dispersing, accumulating way and mechanism of particle. Comprehensively discribing the fractal research of shale partical, introducing experimental testing method of three fractal mension, that is,SAXS and NMR suction methods,and discussing the resolution and the feature in different method.
