When the amount of hydrochloric acid added in hydrolysis process of aluminum ethoxide was relatively high, the formed AlCl〓 could enhance the self-pulverization of fibrillar γ-AlOOH powders during its dehydration process and lead to the formation of amorphous ultrafine alumina powders with the particle size of 3～5nm, which could melt and become glass like at 500℃, and then become spherical by crystallization.

当盐酸与乙醇铝的摩尔比从0.0增加到0.04时，粉末成球温度从1200℃降到500℃；在高酸量时形成的AlCl〓，能促进γ—AlOOH脱水时的自粉碎效应，生成无定形的超细Al〓O〓粉末，粒径为3~5nm，在500℃经熔化形成玻璃态，再晶化成球，而在其它情况下，粉末靠收缩经表面扩散方式成球。

The zircon grains separated from the syenogranite sample in the Chahayan pluton show generally euhedral form with fine oscillatory zoning on their CL images, and high Th/U ratios (0.32-1.12), which exhibit the features of magmatic zircons.

It was suggested that the presence of the BA Langmuir monolayer was responsible for the good orientation of the specimens, and the kinetically controlled diffusion of ammonia at the air-liquid interface provided a driving force for the fractal growth.

认为Langmuir膜的存在导致了材料单一的晶面取向，而氨气在气-液界面的动态扩散提供了分形结构形成的驱动力。

Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.In smooth microwave, the influence of O〓 upon the diamond films＇MWPCVD was investigated. It is found that:1 In the range of lower O〓 concentration, its increase is beneficial to improvement of quality of diamond films, but in that of higher one, its increase conversely deteriorates the quality of diamond films.

在脉动微波下进行了沉积金刚石膜的研究，得到下述结果：1）采用合适的脉动微波，能使金刚石膜的沉积质量显著提高，并能使金刚石膜中的微晶石墨得到几乎完全的抑制。2）过长或过短的平底时间或脉动周期均不利于金刚石膜中非金刚石相碳含量的降低，只有适中的平底时间或脉动周期才有最佳的降低非金刚石相碳含量的效果。3）脉动微波会使金刚石的形核密度有所下降。4）脉动微波下，即使选用较高的CH〓浓度，也能得到沉积质量比在平稳微波下采用较低的CH〓浓度所制备的金刚石膜的沉积质量要明显提高的金刚石膜。

In fluctuating microwave, deposition of diamond films was investigated and some significant results were obtained:1 An appropriate fluctuating microwave can distinctly improve the quality of diamond films, and can grow diamond films almost without microcrystalline graphite.2 Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。
