| 摘 要： | 在二维平面上对扩散—反应过程进行了Monte
Carlo计算机模拟。结果表明，扩散—反应产物形态取决于其界面反应速度与相应组元扩散速度的相对大小。当界面反应为过程的控制环节时，产物趋于紧密的球形；当扩散为过程的控制环节时，产物趋于松散的分枝状。重溶作用使产物形态呈破碎状。

| Abstract: | Monte Carlo
computer simulation of diffusion-reaction process has been made in two dimension space. It
is showed that morphology of the resultant depends on reaction and diffusion speed. When
diffusion is the control link of the process, morphology of the resultant tends towards
fine spheroid shape. While reaction is the control link, it tends towards developed
dendrite form. Resolution of resultant makes it brake. |
