| 摘 要： | 将地层取芯石灰岩样捣碎、筛析、酸溶蚀、测比表面,根据分形理论分析实验结果。在一定条件下,石灰岩颗粒酸溶蚀前后的表面结构具有分形特征,表面不规则性的复杂程度可借表面分维大小加以定量描述。对于给定的石灰岩颗粒,酸溶蚀导致表面分维值增加。

| Abstract: | The surface-fractal dimensions, Df, for a limestone sample before and after hydrochloric acid etching are determined from log-log plots of the specific surface-v vs average particle diameter obtained experimentally by using the relationship deri ed as 2.5248 and 2.7291. The increase in values D_f indicates some complications of surface structure having taken place in the acid etching. The basic aspects of fractal geometry as applied in surface science are presented. |
