胶体中的分形

Fractal in colloids

介绍了胶体与界面化学的基础理论和发展以及溶胶-凝胶方法在各个领域中的应用。对分形理论在胶体科学研究中的应用以及各种求算分形维数的方法进行了综述和总结,指出了现有基本模型和理论的不足和片面性,提出将分形理论引入溶胶-凝胶体系,深入胶体基础理论层面的研究。同时,对实验的局限性和胶体生长的非线性进行了对照,引入了计算机模拟这个有效的手段,并对分形与计算机紧密结合的趋势进行了展望。

The basic theory and development in colloid and interface chemistry as well as the application of sol-gel method in various fields were presented and discussed.The application of fractal theory in scientific research on colloidal phenomena as well the means to obtain fractal dimensions were summarized,with the deficiency and incomprehensiveness referring to the basic theory and existing model in this field highlighted.The introduction of fractal theory into sol-gel system was put forward.At the same time,the limitation of the experiment and the non-linearity of the generation process of the sol-gel were shown.Computerized simulation as an effective means and the trends of the combination of computer model and the fractal research were prospected.
