Based on classical theory of surface diffusion and evaporation-condensation, a fi- nite element program is developed to simulate the unstable shape evolution of plate-like grains.
基于物质表面扩散和蒸发－凝结的经典理论，对板状晶粒不稳定外形的演变过程进行了有限元模拟结果表明，热蚀沟角θ＝０（无内晶界）时，板状晶粒将直接圆柱化；当内晶界存在时，存在一临界热蚀沟角θｍｉｎ；当θ＞θｍｉｎ时，板状晶粒沿晶界分离。
BCF spiral growth mechanism for the surface diffusion model was analyzed using the kinetic data of the four faces.
选取了TGS晶体的 (0 0 1) ,(110 ) ,(0 10 )和 (10 0 )四个面为研究对象 ,分析讨论了TGS晶体的表面扩散螺位错生长机制 ,发现生长基元的脱水化进入表面层过程与表面扩散过程相比 ,前者在TGS晶体的生长过程中起着更重要的作用 ;同时 ,在较高的相对过饱和度下 ,观察到了TGS自然结晶体的两种简单晶形 。
The neck equation given by the coupling model is greater than that given by surface diffusion modal.
结果表明：在相同条件下，多机制综合作用颈长方程略高于表面扩散机制单独起作用的颈长方程；多机制综合作用的对心收缩小于只考虑晶界扩散和体积扩散的对心收缩。
