Effect of the crystal nucleus of zno and zno - fe2o3 on glass - ceramics microstructure 3晶核剂对微晶玻璃显微结构的影响
In the experiment of the number of nuclei change , there are two nucleation conditions considered 在体系晶核数目m变化的实验中,考虑了两种成核情况。
Effects of nucleation agents tio2 and cr2o3 on the crystallization behavior of building glass - ceramics of metallic tailings 3作晶核剂对尾矿微晶玻璃析晶的影响
For seeding a cold spot has been provided on one of the cooling pipes allowing nucleated freezing to be initiated 在冷却管线的一边有一个冷点,容许晶核冷冻开始。
The heat treatment process and effects of the nucleation agent on the nucleation and crystallization were explored 探讨了微晶玻璃的热处理工艺制度及晶核剂对核化、晶化的影响。
The results indicate that phosphate film forms at first at the boundaries between ferrite and graphite 结果表明,磷化膜晶核首先在铁素体石墨界面等处形成,是一个不均匀形核过程。
And the exponential growth of the number of nuclei has sharper effect on the course of crystallization than the linear growth of its 并且,晶核数目指数增加比线性增加对结晶过程影响明显。
Their growth mechanism could be attributed to the substrate - induced oriental nucleation and fast growth under thermodynamic equilibrium state 其生长过程可以概括为衬底诱导的趋向氧化锌晶核在平衡状态下的快速生长。
The result of annealing of silicon nitride showed the crystal nuclear existing in the origin silicon nitride powder led on the grow of hexagonal 3 - si3n4 and formed the 3 - si3n4 氮化硅的煅烧表明:原始氮化硅纳米粉末中的晶核在氮化中诱发相生长,形成- si _ 3n _ 4 。
When ph value < 0 . 5 , faster deposition rate , faster growth rate of crystallizing nucleus , which causes bigger crystalline granularity and bad surface quality of the deposits such as crassitude or darkling Ph 0 . 5时,沉积速度过快,晶核成长速度快,晶粒粒度较大,镀层表面粗糙、发黑,表面质量差。
