By the analysis of coating ratio , oxidation ratio , micrograph and particle size of composite particle , it was found out that factors such as ph value , coating temperature , concentration of premonitory matter solution mainly affect the coating layer forming 通过包覆率、氧化失重率、形貌观察、粒度和比表面积等分析发现，非均匀成核过程中溶液ph值、包覆温度、覆层前驱物浓度等这几个因素对石墨表面覆层形成有着重要影响。
In order to understand the frost crystal growth , the nucleation process on the cold plate with constant temperature was investigated . the experimental results revealed that the lower the cold plate temperature is , the shorter the frozen time of water droplets , and the smaller the frozen water droplets 为了加深对晶体生长阶段的认识,本文对某一具有确定温度的冷壁面突然与一定环境条件下的湿空气接触时冷壁面上的成核过程进行了研究。
In order to improve the adherence of the film to the substrate and the repeatability of synthesis , we invent a three - step approach , which comprised the steps of turbostratic boron nitride ( tbn ) turning into rhombohedral boron nitride ( rbn ) as the first , rbn turning into cbn as the second and deposition as the last 基于对bn薄膜相结构的分析和优化的沉积条件,制备出立方相含量高达95 %的cbn薄膜。为了改善制备的可重复性和粘附性,提出了三步沉积方法,即将成核过程分成tbn转化为rbn和rbn转化成cbn的两步,加上之后的沉积过程。
