项目摘要
Based on experimental studies on grain boundary diffusion and segregation, we are able to show the negligible role of grain boundaries on chemical evolution of the earth interior. Further, using our accumulated knowledge of grain boundary properties, we are able to demonstrate superplasticity of the minerals and to propose grain growth law as a function of mineral fractions.
基于关于晶界扩散和隔离的实验研究,我们能够显示晶界对地球内部化学演化的作用可忽略的。此外,利用我们对晶界特性的积累知识,我们能够证明矿物质的巨型性,并提出晶粒生长定律作为矿物部分的函数。
