The material granule geometry and the hole geometry display the minuteshape characteristic from the atomic criterion to the crystal grainsize scope in. (Minute shape characteristic - fractal characteristic) As a result of its porosity distribution and size randomness,this article uses the stochastic function law to carry on to thematerial digs the hole.
The particle and pore geometry from the atomic-scale geometry of the size range of display fractal characteristics. (Fractal characteristics -- fractal characteristic) because of its pore size distribution and Randomness, the paper random function of the material dug hole.参考资料：http://www.google.cn/language_tools?hl=zh-CN 已赞过已踩过<
