晶体中空位气体的溶解与晶界扩散
The dissolution of the vacancy gas and grain boundary diffusion in crystalline solids
摘要：
本文根据应力或张力作用下固体中空位数密度的计算公式，建立了晶态固体中的晶界扩散模型。我们得到了晶界扩散激活能（取决于表面张力或晶界能量）以及空位和扩散物种在晶界附近的分布。
英文摘要：
Based on the formula for the number density of vacancies in a solid under the stress or tension, the model of grain boundary diffusion in crystalline solids is developed. We obtain the activation energy of grain boundary diffusion (dependent on the surface tension or the energy of the grain boundary) and also the distributions of vacancies and the diffusing species in the vicinity of the grain boundary.
