Diffusion Coefficient and Internal Pressure CRITICAL LARGE DEFORMATION LOAD FOR INTERNAL PRESSURIZED THIN CYLINDRICAL SHELL 扩散系数与内压受内压圆筒的临界大变形载荷计算
It is considered that the rate controlling step of nitridation process is a diffusion procedure of passing nitrogen through the nitride shell which formed on silicon surface, and so a model enabled to explain the mechanism of diffusion may be proposed. 认为:氮化过程的限速步骤是氮气通过在硅表面上的氮化物壳层的扩散,并提出一种解释扩散机理的模型。
In the third stage, the diffusion becomes slower as the shell thickness increases. 在第三阶段中,随着壳层厚度增加,扩散变慢。
A diffusion and consumption process was proposed to explain the formation of ZnO/ ZnS core/ shell nanocomposites. 提出了扩散&消耗机理以解释管状ZnO/ZnS核/壳结构纳米复合材料的形成过程。
