On the basis of atmospheric corrosion analysis and on the premise of unaltered originappearance of metal antiquity, a novel systematic technology of rust stabilized conversion and corrosioninhibition for archeological iron was developed in this thesis. Model occulted corrosion cell was used to studythe formation of bronze powder rust, its characteristics of pit corrosion and effect factors. The filmingtreatment of azoles composite corrosion inhibitors was used to prevent silver tarnishing, and its anti-tarnishingmechanism was proposed by measurement of electrochemical techniques and Surface-enhanced Ramanscattering.

Bisbenzimidazolium salts were used as a tetrahydrofolate coenzyme model, and thus the biomimetic synthesis of twenty-four acyclic diketones as precursors for macrocyclic ketones was successfully accomplished by using the addition-hydrolysis reaction of the bisbenzimidazolium salts with alkyl magnesium halide, wherein six diketones have not been reported in literature.

在本文中，受四氢叶酸辅酶的一碳单元转移反应的启发，作者以双苯并咪唑盐作为四氢叶酸辅酶模型，利用格利雅试剂与双苯并咪唑盐的加成-水解反应，成功合成了二十四种作为麝香酮及类似大环酮重要前体的长链二酮，同时，提供了一种麝香酮及类似大环酮的仿生合成新方法。

Objective:This study is investigate the different dosage midazolam on the sedation、inhibit stress reaction、anterograde amnesia before epidural anesthesia.

目的：本研究的目的是比较硬膜外麻醉前给予不同剂量的咪达唑仑对患者镇静、顺行性遗忘和应激作用的影响，探讨咪达唑仑术前应用的适宜剂量，以利于病人的术中心理保护和术后康复。

Four substances including 2-methyl ethyl acetoacetate and barley straw extract distilled from bulrush as well as cetyl trimethyl ammonium bromide and isothiazo lintone were used for the comparison experiment in inhibiting the growth of Microcystis aeruginosa in various phases. Result showed that inputting chemicals in the lag phase has better effect than in the log phase, and adding in lag phase can effectively inhibit the algae growth. Although feeding allelopathic substance at log phase can lead to certain restraining effect, it cannot result in the effective inhibition of algae growth, which can be well achieved by feeding CTAB and isothiazo lintone below 10mgl/L during log phase.

研究用从芦苇中提取的2-甲基乙酰乙酸乙酯和大麦秸浸出液两种化感物质以及十六烷基溴化钱和异噻唑啉酮等四种药剂对不同生长期的铜绿微囊藻进行了对比抑制试验，结果显示在铜绿微囊藻生长的迟缓期投加试验药剂效果比在对数期投加效果都好，在迟缓期投加四种药剂，都有很好的抑藻效果；在铜绿微囊藻生长的对数期投加化感物质，虽然有一定的抑藻率，但效果较差，而在藻对数期投加10mg/L以下的CTAB和异噻唑啉酮能达到很好的水华抑制效果。

The photoinduced cis-trans isomerization reaction occurs after photo-irradiation of this compound, and the rate of conversion depends strongly on the polarity of solvents used.

八 研究了C5位联有含氮茋的三芳基-2-吡唑啉化合物(TPP15)的光物理行为，发现：该化合物在不同极性溶剂中的荧光量子产率值呈倒钟形状，这与在不同极性溶剂中邻近效应的大小以及吡唑啉环和含氮芪基团间的电子转移的难易程度有关。

Chiral ligands mentioned above and their complexes with acetate copper were used as enantio-selective catalysts in asymmetric cyclopropanation reactions of diazoacetate and 1,1-diphenyl ethylene. Investigations indicate that all of them reveal certain optical-selective capability, but chiral C2-symmetric 2,6-bispyridine ligands show better catalytic capability than chiral asymmetric schifF-base ligands.

选择了2个手性2，6-吡啶双噁唑啉配体和6个手性不对称席夫碱配体与醋酸铜形成的配合物作为催化剂，对重氮乙酸乙酯与1，1-二苯乙烯不对称环加成进行催化反应，发现这8个催化剂对1，1-二苯乙烯的不对称环丙烷化反应都表现出了一定的光学活性诱导能力，手性2，6-吡啶双噁唑啉-铜类具有比手性Schiff碱-铜类更好的催化性能。

Alga-removal effects of both algicides used in combination showed synergistic action. The proportion ofbromogeramine to isothiazolone being 4.3 to 1 gave best result.
