| 摘 要： | 自修复是自然界普遍存在的现象.本文从几何约束的角度用计算机模拟了矩形和等腰梯形微细管道中的胶粒结晶,并重点对胶粒结晶的自修复特性进行了研究,得到了许多有意义的结果.模拟发现,当引入一个半径与众不同的大胶粒时,将引起结晶的混乱,而这种混乱在一定条件下可以自修复.本文较全面地研究了大胶粒半径、微管宽度与胶粒半径之比、梯形底角对胶粒结晶自修复的影响,得到了在矩形和等腰梯形微细管道中能够产生自修复的阈值条件.

| Abstract: | Self-healing is a general phenomena in nature.It is significant to study the rule of self-healing.In this paper,that colloid crystal in rectangle and trapezoid micro-channel was simulated by computer,and the self-healing of colloid crystals was mainly studied.It was assumed that the interaction between the particles was represented solely by hard-sphere repulsion.In the simulation,the colloid crystals were destroyed,and self-healed when a big colloid appears in the micro-channel.The threshold value of self-healing in rectangle and trapezoid micro-channel was found by studying the affect to self-healing provided by the radius of big colloid,the rate between micro-channel's width and colloid' radius and the shape of trapezium. |
