当薄膜生长温度低于单原子的扩散温度时,表面原子的成核和表面岛的生长主要是由沉积原子的空间随机性和表面原子密度增加而决定的,随着薄膜生长温度的提高,薄膜的生长模式则取决于单原子的层内扩散和层间扩散的竞争。

Precursors of sulfates and alkali halides prepared in co-deposition process were mixed homogenously, annealed at high temperature and then formed CoO and NiO fibers, XRD, XPS, Raman and SEM were used to characterized the samples, the growth of these fibers might be a special LS mechanism: soluble precursors in molten salt decomposed gradually to form initial crystal nucleus and succeeding particles adhered to these nucleus and grew anisotropically in the special high temperature fluent medium, the higher decomposition temperature and solubility of the precursor are two key factors in this method, which are in favor of a longer growth process and result in larger sizes of the final metal oxides crystals.

以共沉淀方法生成硫酸盐与碱金属卤化物融盐的均匀混合前驱物,在高温下退火制备出了CoO和NiO的晶须,以XRD和XPS等对成份进行了分析,SEM分析了形貌特征,研究了不同前驱物热分解特性,认为本方法是一种简单的LS生长机制:可溶性前驱物于融盐中热分解后逐渐析出成核,后续的粒子附着在核上,在融盐环境下沿一定方向作准一维生长,其产物形貌之不同源于硫酸盐的高分解温度和在融盐中的可溶性,导致晶体生长过程中成核过程与生长过程竞争的结果对一般前驱物结果的偏移。

The temperature of cold injury was abo ut 0 ℃ to 15℃,While hot injury would appear when temperature got to 36℃.These ind icat ors were varied in different species,and the greatest difference was the temper ature of cold injury.Growth would be poor in summer under full illumination,whi le part shading was beneficial.The best condition was 70 percentage of sh ading for Araceae and 50 percentage of shading for Agavaceae.The need for soil moistu re was strict.Most of species would grow normally in 65 to 85 percentage of soil m o isture.The characters responsed to illumination,temperature and soil moisture w e re consistent with their original ecologic environment.

其最 适生长温度在16-35℃,除酒瓶兰外,低于10℃时均表现生长停滞状态;寒害温度差异很大,天南星科为0-15℃,龙舌兰科为0-10℃,大多数植物在36℃会产生热害;光照对其影响较大,夏季这两科植物在全光照下长势差而在一定荫蔽的条件下有利生长,最佳荫蔽度天南星科为75%,龙舌兰科为50%;这两科植物对土壤中的水分含量要求较高,大多在土壤含水量70%以上才能正常生长,这些光、温、湿的反应特性与其起源地湿热和荫蔽的生态环境相吻合。

This invention exposed the method of producing high performance cannular sapphire. It uses once-fashioning wetting EFG technology. It draws the cannular sapphire with required inner diameter and outer diameter and length from melt. Firstly, the size and specification of cannular sapphire need to be determined, then according to it to produce the matching cannular die. Then selecting sapphire particleboard from flame fusion method as raw material, and secelting the good seeding grew in (0001) direction by Czochralski method to grow cannular sapphire. The transverse temperature difference is within 2DEG C, the lognitudinal temperature grads within 10mm of die end face is 3-4DEG C, the growth speed is 30-40mm/h.
