优越性

Comparing with conventional air handling process, the liquid desiccant air-conditioning system can dehumidify air without cooling down to its dew point. Meanwhile, counteraction cooling and heating can be avoided, which usually happened in conventional air handling process and led to huge energy waste. In addition, during the air handling process no condensation water separates out of the air in the liquid desiccant air-conditioning system, thus, avoid fungi thrives in moist environment of traditional air handling process. Not only being applied in dehumidification process in summer, the system can also realize humidification process in winter conditions efficiently.

与传统的空气处理方式相比，采用溶液式空气处理方式，具有如下优越性：取消了冷凝水表面，消除了霉菌等生长所需的潮湿环境；既可以对空气除湿处理，又能实现冬季对于空气的加湿处理过程；可方便调节处理后的相对湿度，不再是常规冷凝除湿方式中接近100%相对湿度的出口空气参数；避免了常规空调系统冷凝除湿后温度过低还需再热带来的冷热抵消问题；可以充分利用低品位能源如太阳能和废热实现溶液再生，节省系统电耗。

This work, concentrated on the asymmetric allylation of aldehydes controlled by different chiral auxiliaries prepared from rotational pure tartaric acid, can be divided into three parts.The first part aims to review the developments of chiral drugs and asymmetric synthesis, from which derived the present research topic backgrounds and works.Synthesis and applications of allylation from aldehydes are the second part of the thesis. By optimizing the reaction conditions, such as solvents, temperature, time and chiral auxiliaries like N,N\'-dibenzyl tartamide, N,N\'-p-dimethylphenyl tartamide, N,N\'-o-dimethylphenyl tartamide, N,N\'-o-dichlorophenyl tartamide, N,N\'-a-dinaphyl tartamide, N,N\'-dicyclohexyl tartamide and N,N\'-diphenyl tartamide, ideal experimenttal conditions are obtained according to HPLC monitoring, as well as the auxiliaries\' recoveries experiments. Starting from benzaldehyde and 3-bromopropaldehyde, N,N\'-dibenzyl tartamide is considered the best auxiliary in this reaction.

本文介绍了醛的不对称烯丙基化反应，以光学纯酒石酸为原料，研究了不同构型手性配体在醛的烯丙基化反应中的立体选择性，全文共分三部分十个章节：第一部分对当前手性药物和手性技术进行了概述，并由此展开了本文的研究背景和任务；第二部分为有机合成部分，对醛的不对称烯丙基化反应进行了深入探讨，以苯甲醛为原料对反应条件进行优化，在优化的反应条件下对制备的七种可回收手性酰胺配体(N-苄基酒石酸二酰胺、N-对甲苯基酒石酸二酰胺、N-邻甲苯基酒石酸二酰胺、N-邻氯苯基酒石酸二酰胺、N-a-萘基酒石酸二酰胺、N-环己基酒石酸二酰胺和N-苯基酒石酸二酰胺)进行筛选，优化配体回收实验条件，最终确定出N-苄基酒石酸二酰胺在苯甲醛的不对称烯丙基化反应中具有较大优越性，结晶回收的手性配体光学纯度保持不变。

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

眶壁重建是其矫治的首要条件，然而，眶壁形态复杂，并有视神经由眶尖通过，加之术野受限，使精确的解剖复位很难完成，本文应用CAD/CAM技术，术前成型钛网并行眶壁重建，通过CT分析和眼科检查，证实该技术在眶壁重建的精确性上均较传统方法有明显提高，其中，眶内壁的修复程度和眶底修复形态的对称性，以及眶容积缩小程度反映了其形态修复的精确性，而置入深度则体现了在缺损修复范围设计中的优越性。
