| 摘 要： | 本文借助分形几何理论 ,探讨垂直剖面上玄武岩红土在加分散剂前后颗粒粒度的分维变化特性。研究结果表明 :不论是否加分散剂 ,红土的颗粒粒度都存在线性分形结构。不加分散剂 ,存在两个无标度区 ,沿剖面从上到下 ,分维值逐渐增大 ;加分散剂 ,存在一个无标度区 ,沿剖面从上到下 ,分维值逐渐减小。分维值的大小反映了红土中颗粒粒度的变化特点

| Abstract: | In terms of fractal geometry, analyses are performed of the features of grain size of the basalt laterite with and without disperser at the vertical section. The results show that linear fractal features exist in the grain size of laterite. There are two liner zones at the fractal lines if no disperser is added and fractal dimension values increase from the top to the bottom of the section, and only one zone if disperser is added and fractal dimension values decrease from the top to the bottom. The fractal dimension value can be used to describe the variations of the grain size of laterite. |
