spherical grain 中文意思是什麼
spherical grain
解釋
球形顆粒-
When sno2 wt % was controlled for 10 %, the square resistance of sn - in2o3 was minimum. through the characterization of in2o3 / sno2 nano powders, some conclusions were drawn : sno2 nano powder is rutile structure, and in2o3 and sn - in2o3 nano powders are cubic structure. in2o3 / sno2 nano powders were well dispersing with spherical uniform grain, and the mean grain was 4 - 50 nm
通過對inzo3 / snoz納米粉體表徵，得出inzo3 / snoz納米粒子多呈球形、顆粒均勻、分散性良好、組分均勻、純度較高、平均粒徑在4一50lun左右、比表面積達67一156mz / g ; snoz納米粉為正四面體金紅石結構， inzo3和sn一inzo3納米粉為體心立方結構。 -
The effects of the fabrication conditions on the crystal structure, grain size, micromorphology and electrochemical performance of these materials have been studied in depth. the reaction mechanism of the low - heating solid - state reaction method has also been investigated. in addition, a novel electrochemical method ( rpg method ) based on the concept of " ratio of potentio - galvano - charge capacity " has been for the first time developed to determine the diffusion coefficient of lithium - ion within insertion - host materials on the basis of the spherical diffusion model
本論文較系統地考察了低熱固相反應法合成鋰離子電池正極材料的可行性問題，研究了工藝條件對材料的晶體結構、晶粒尺寸、微觀形貌及電化學性能等的影響，探討了低熱固相反應的機理，並通過引進「恆壓-恆流充電容量比」的概念，給出了一種測定鋰離子嵌入脫出固相擴散系數的新方法。 -
The results of transmission electron microscopy ( tem ) showed that the grain of strontium titanate powder prepared was spherical and the grain sizes distribution were homogeneous
通過tem分析可以看出，制備的鈦酸鍶粉體材料的顆粒為球形，並且顆粒大小均勻。 -
To explain the inverse hall - petch relation in nanocrystalline metals, a geometric model is made, which assumes that the grains are spherical crystals, and the thick of grain boundary is considerable compared with the microcrystalline metals
提出了一個球形晶體純晶界滑移幾何模型，得到出現反hall - petch關系的條件和小晶粒尺寸條件納米晶金屬材料的強度極限。
