The study of Curcumine on oleic acid-induced acute lung injury in rats During the experiment, acute lung injury was induced by oleic acid in rat. The changes of dynamic lung compliance were recorded by anrise2005 pulmonary function test apparatus, light microscope was used to examine histological changes and lung index as well as wet to dry weight ratio was calculated by weighting method.

急性肺损伤是由多种原因引起的以肺泡毛细血管膜通透性增高为特征的肺损伤，是临床重症监护病人主要的死亡原因，死亡率达到30%-50%，其严重形式是急性呼吸窘迫综合症，迄今仍无有效治疗ALI和ARDS的方法和药物。

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.

本论文基于环糊精对被包结客体光谱性质的改变，开展了两大方面的研究：β-环糊精对姜黄属植物根茎主要成分—姜黄素、中药茜草有效成分—茜草双酯、抗麻风药物氨苯砜及抗炎药物萘丁美酮的主-客体识别反应机制研究：借助超分子包合物的紫外吸收光谱、荧光光谱或红外吸收光谱等手段，通过多种方法探讨并验证了超分子包合物的形成；研究了直链醇的加入对超分子体系的影响，揭示了三元体系中非共价相互作用导致超分子包合物表观结合常数降低的原因：对超分子包结反应进行了热动力学研究，探讨了各热动力学参数的变化趋势并从熵焓互补的角度考察了超分子包结过程；通过荧光猝灭实验进一步揭示了水相中β-环糊精增敏客体荧光的本质原因，从而为超分子化学提供新的理论和研究方法。

This part Measures firms" size with market value of float shares, and divides each portfolio into quintiles and deciles to choose an appropriate grouping method. The second part divides the sample into two sub-samples to tests the different performance of "small firm effect" in two periods. The third part tests different performance of each month. The fourth part studies the "small firm effect" in five industries, the industry, the commerce, the public utilities, conglomerates and the properties, and uses Fame-Macbeth method to research "the small firm effect" in the different industries. The fifth part analyzes the reason why the "small firm effect" exists in China stock market referring to the western explanation about "the small firm effect and the character of China stock market. In the end, we provide some suggestion.

论文运用实证方法检验中国股市&小公司效应&的存在性，用流通股市值作为公司规模大小的度量，用五分组和十分组两种分组方法检验中国股市&小公司效应&的表现；把整个样本区间以2001年为界分为两个样本子区间，检验&小公司效应&在不同时间阶段的表现有何不同；分月检验&小公司效应&在不同月份的表现；把样本中所有上市公司按照行业分为五大类，工业类、商业类、公用事业类、房地产类和综合类，利用Fama-MacBeth法检验中国股市&小公司效应&在不同行业的表现；联系国外关于&小公司效应&存在原因的解释，结合中国股市的实际，分析中国股市&小公司效应&存在的原因，并提出了一些建议。

Authorities at first blamed an engine explosion, but six months later, they charged five mechanics with improperly repairing and re-connecting a part of the autopilot system, in a way that would have made the plane nearly impossible to control.

调查部门一开始将事故原因归咎于发动机爆炸，但6个月后，5名机械师因此事故被追究责任，原因是他们对飞机的维修不当以及重新连接自动驾驶系统中某一部件后，造成飞机几乎无法控制。
