The present invention is suitable for aluminum casting requiring high antiwear property and Al-Si alloy with smelted waste material.

本发明适用于要求耐磨性高的铝铸件，以及熔化大量废、旧零件以及切屑的铝硅合金。

Through the morphological observation on silicon particles of Al-Si-Cu-Mg cast alloy, it is found, that during solution heat treatment the evolution of eutectic silicon morphology and their effect on mechanical property can be classified into three stages. In the initial stage, necking, stubbing and fragmentation of silicon particles results in an improvement in plasticity of the alloy. In the intermediate stage, the mechanical properties of the alloy attain peak values due to the spheroidization of silicon particles.

在固溶处理过程中，共晶硅相形貌发生了显著的变化，并对合金的性能产生了很大的影响；通过定量金相分析，共晶硅相形貌的演变及其对合金力学性能的影响可划分为三个阶段：固溶初期硅相的熔断和钝化使合金的塑性得到显著的提高；固溶中期以粒化为主，合金的力学性能达到了峰值；固溶后期硅相的粗化符合LSW粗化模型，硅相形貌呈现棱角小面特性，合金性能降低。

The low temperature buffer layer was epitaxied on the Si substrate at the temperature of 300°C. Non-finite ZnO was grown on the substrate due to the low temperature at which the Zn and O atoms is easy to be absorbed on the substrata, which could relaxed effectively the effects of the lattice mismatch between the substrate and ZnO thin films on the quality of the ZnO films and could reduce the formation of distortion and defects.

在 300℃温度下生长了一层 ZnO 薄膜，由于生长温度较低 Zn、O 原子容易被吸附到衬底的表面导致非定形的 ZnO 的生长，有效减缓了衬底与 ZnO 之间的晶格失配带来的影响，降低了失配位错和缺陷的产生。

Results The SiO2-ZrO2 composites were calcined at 200℃ prior to sulfating, the concentration of sulfuric acid was 1.0 mol/L ,the molar ratio of Si and Zr was 15, the calcination temperature was 500℃, the molar ratio of ethynol and lactic acid is 3/1, the yield of the ester could reach 92.7%.

结果SO4^2-／SiO2-ZrO2固体超强酸催化乳酸乙酯的合成反应适宜的反应条件为：预焙烧温度为200℃，浸泡硫酸浓度为1.0mol／L，硅锆摩尔比为15，焙烧温度为500℃，醇酸比为3时，酯化率可达92.79／6。

NANJING、 China --- The view from where Chen Si stood on the Landmark Yangtze River Bridge captured the frantic、thrumming energy of China .

在南京大桥这个地标上，从陈思站立的地方放眼望去，可以捕捉到中国巨大且隆隆作响的活力。

Besides volunteering for recycling duty, Hanqi also transcribes Jing Si Aphorisms; it helps control his condition.

慈济温暖关怀陪著一家人渐渐走过生命低潮，现在他们也每天存下善念，要把这份爱分享出去。

We join German Si in September, 2004 to come the luck near the group, has internationally this in rubs truncates thedomain to have absolutely the authoritative group company is thestrong backing, we have the confidence can achieve in the engine beddevelopment and the optimization conform to the customer and themarket demand, we in aspect and so on scientific research,development, manufacture, material, sale as well as service mightshare together act according to the huge potential which thesuccessful experience will produce .
