银超微粒扩散中的孤立波拢动

The disturbance of solitary wave in the diffusion of Ag ultrafine particles

以银超微粒为例提出了一个描述超微粒自发演化的“扩散提获．反应．凝聚”的模型，建立了它的演化动力学方程，同时求得了演化动力学方程的孤立破解，并对解作了较详细讨论．

The model of 'Diffusion-Trapping-Raction-Aggregation 'about describing utlrafine auto-evolution isprojected, example for Ag ultmfine. And its kinetic equation of evolution is established. At the sametime, the solitary wave solution of the kinetic equation is obtained. And then the solution is discussedminutely.
