Fabrication of Alumina-based Aerogels

伴随着高超音速航天飞行器、热电池以及工业窑炉等的迅猛发展，对隔热保温的要求越来越高，目前使用广泛的氧化硅气凝胶隔热保温材料已经无法满足应用要求，因此迫切需求一种更耐高温、轻质高效的隔热保温材料。 以仲丁醇铝（ASB）为前驱体，水（H2O）为反应物，乙醇（EtOH）为溶剂，乙酰乙酸乙酯（Etac）为螯合剂，冰醋酸（Hac）为催化剂，通过分步水解和螯合剂的双重作用有效地控制仲丁醇铝的溶胶-凝胶过程，最后经乙醇超临界干燥制得氧化铝气凝胶。实验研究了水、乙醇、和乙酰乙酸乙酯等工艺参数对制备氧化铝气凝胶的影响，最后得到最优物料配比n（ASB）：n（H2O）：n（EtOH）：n（Etac）：n（Hac）...With the development of the new ultra-high speed aircraft, military thermal batteries, industrial furnaces and so on, higher and higher requirements have been put for heat-insulation materials. However, the widely used silica aerogel materials have been unable to meet the application requirements. Therefore, there is an urgent need in designing and synthesizing heat insulation material with higher...学位：工程硕士院系专业：材料学院_工程硕士(材料工程)学号：2072014115013

Initial analysis on forbidden to apply moxibustion on Yinshi(ST 33)

历代许多医籍都将阴市穴定为禁灸的穴位,然临床上以艾灸阴市穴治疗疾病者并不少见。故文章在总结目前常见的禁灸原因基础上,就这一禁忌进行深入探讨,认为以热证禁灸,防止血管和神经损伤,防止感染,影响美观,孕妇的腹部和腰骶部不宜施灸,毛发丛生处不宜灸,古代医家误判、后人继承等说法不足以阐明阴市为何禁灸。最终得出“阴市禁灸“这一禁忌缺乏科学依据支撑的结论,临床上但灸“阴市“一穴无妨。Many medical books have deemed Yinshi(ST 33) as the moxibustion-prohibited-point in the past dynasties.However,moxibustion on Yinshi(ST 33) to treat diseases was not rare in the present clinical.So this paper made an indepth exploration on this taboo based on the summary of common reasons of moxibustion prohibited.It is thought that the heat syndrome was forbidden to apply moxibustion,in order to prevent vascular and nerve damage,infection and affect appearance.Abdomen and lumbosacral portion of pregnant woman and the body parts of hair growth were forbidden to apply moxibustion.The opinions as ancient physicians' misdiagnosis,inheritance of later generations and so on were not enough to clarify the reasons for making Yinshi(ST 33) as the moxibustion-prohibited-point.At last,the conclusion lacking a scientific basisas 'forbidden to apply moxibustion on Yin shi(ST 33)' was obtained,and there was no harmto apply moxibustion on Yinshi(ST 33)
