Highly ordered mesoporous Zr-Ce-SBA-15 silica with hexagonal-platelet morphology was synthesized through a hydrothermal route by using pluronic P123 as a template, tetraethyl orthosilicate as a silica source, zirconyl chloride and cerous nitrate as a precursor. The main strategy of this method was to utilize the acidity self-generated from the hydrolysis of inorganic salts in the aqueous solutions, where no addition of mineral acids was necessary.

The results show that the TiO2 porous films can be obtained by anode oxidation using 10% H2SO4, voltage of 120V on the surface of Ti-6Al-4V alloy, and the aperture size is about 100-200nm. The acerate CaHPO4 with size of 200-400nm can be gained by the electrochemical deposition. Ultimately, the acerate CaHPO4 changed to the sheet Ca10(PO4)62 after being treated with 0.1mol/L NaOH in autoclave at 200℃ for 10 hours .

结果表明:钛合金(Ti-6Al-4V)板经以10%的硫酸为电解液和电压为120V时阳极氧化,产生孔径大约为100-200nm的多孔氧化膜,再经电化学沉积,得到尺寸大小约200-400nm针状的CaHP04,最后经盛有浓度为0.1mol/LNaOH 水溶液、温度为200℃的高压釜中水热合成10h,针状的CaHP04 转变为片状的Ca10(PO4)62。

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。
