On the basis of macroscopic simulated results , polycrystal model including grain boundary zones was established to model the mesoscopic processes 在宏观模拟结果基础上，通过建立包含晶界影响区的多晶模型，对宏观拉伸试样颈缩微区的细观变形过程进行了数值模拟分析。
The performances of multicrystalline silicon solar cells were improved after porous silicon heavy phosphorous diffusion passivation and low frequency plasma hydrogen passivation 通过多孔硅重磷扩散钝化及低频等离子体氢钝化等多晶硅太阳电池晶界钝化，改善了太阳电池性能。
The micromorphology and grain boundary microstructure of the material were studied with sem and tem ; the grain boundary phase composition of the material were analyzed with eds and x - ray 利用sem 、 tem研究了材料的微观形貌和晶界显微结构特点，用eds 、 x - ray分析了材料晶界的相组成。
The particles on the boundaries , which are bigger than that in the grains , have varied shape , such as spheroidal , chain and drop , when the category of rare earth or the sintering technology are changed 依添加种类和烧结工艺的不同晶界上的颗粒有多种形状，如球状、链状、液滴状等。
The ubiquitous hypothesis that the actions between grain boundary and second - phase participle are balanced everywhere in the existed models is excluded in the physical model developed in this thesis 本文建立的物理模型成功地避免了已有模型普遍存在的晶界与二相粒子处处作用平衡的假设。
At the same time the required hypothesis of cohence and non - cohence between second - phase participle and grain boundary is also excluded when the model are worked out from the perspective of geometry 同时，本文模型还避开了从几何角度推导模型必需的二相粒子与晶界之间的共格或非共格的假设。
This physical model in the thesis accords with the process of action between second - phase participle and grain boundary by examining the process of development of this physical model and physical basis 从模型的推导过程和物理基础来看，本文建立的模型更为符合二相粒子与晶界之间的作用过程。
6 . the melting of the grain boundary is the reason of the semi - solid grain globalization , and its control factors were the atomic diffusion velocity and the liquid - solid interface curvature 6 、半固态晶粒球状化的基本原因是晶界熔化，其控制因素是因液界面处原子扩散迁移的速度和界面曲率。
The distribution or the morphology of grain boundaries , dislocations and precipitates in crystalline silicon were observed by scanning infrared microscopy ( sirm ) , and much useful information was obtained 通过红外扫描仪观察晶体矽中的晶界、位错和不同金属沉淀的分布和形貌，并分析其相关信息。
The physical properties of cerarnics are ciosely related to their microstructure such as the grain scale , grain boundny , grain orientation , etc . it ' s helpful for the development 陶瓷的物理性能与其相应的微观结构之间存在着密切的相互联系，如晶粒尺度、晶界、晶粒取向等都对物理性能有影响。
