Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

Reductive conversion of geraniol to citronellol is adopted as a model reaction, and several factors in the reaction are discussed using gas chromatography method. The influence of n-hexane and butyl acetate, as organic solvents, on biocompatibility was studied; the influence of methanol, ethanol, glycol, n-butanol and 1-hexanol, as energy substance, on the transformation efficiency was compared, respectively; the catalysis capabilities of Baker's yeast, XST-KO yeast, LP yeast, alcohol yeast, dry yeast, Saccharomyces cerevisiae, Angel yeast and Meishan yeast were discussed. It has been proved that biocompatibility of n-hexane are much better than that of butyl acetate, and the hexane has been demonstrated the most effective in terms of the influence on biotransformation, Baker's yeast has shown the highest tranformation efficiency among the eight yeast strains.

以香叶醇转化为香茅醇作为模型反应，通过气相色谱法进行定性和定量分析研究了影响该有机相生物转化反应的几个基本因素，考察了两种有机溶剂正己烷和乙酸丁酯对生物相容性的影响，选用甲醇、乙醇、乙二醇、正丁醇和l-己醇分别作为能量物质进行实验，比较其对转化的影响并探讨了Baker's酵母、XST-KO酵母、LP酵母、酒精酵母、假丝酵母、干酵母、安琪酵母和梅山酵母八种不同酵母作为生物催化剂对模型反应的催化能力，结果表明，正己烷作为有机溶剂，其生物相容性明显好于乙酸丁酯，更加有利于该生物转化反应进行；乙二醇作为能量物质，该模型反应转化率最高；而 Baker's酵母作为生物催化剂，对该模型反应的催化能力最强，最适合作为该模型反应的催化剂。

Suzanne Vega - Tom's Dinner I am sitting in the morning At the diner on the corner I am waiting at the counter For the man to pour the coffee And he fills it only halfway And before I even argue He is looking out the window At somebody coming in "It is always nice to see you" Says the man behind the counter To the woman who has come in She is shaking her umbrella And I look the other way As they are kissing their hellos I'm pretending not to see them And instead I pour the milk And I open up the paper There's a story of an actor Who had died while he was drinking It was no one I had heard of And I'm turning to the horoscope And looking for the funnies When I'm feeling someone watching me And so I raise my head There's a woman on the outside Looking inside. Does she see me?

清晨， 我坐在拐角处的小饭馆在吧台前，等那个男人给我倒咖啡他居然只倒了一半的量---我正想跟他抗议他看向窗外，有人快要进来"见到你总是很高兴"吧台后的男人对进来的女人说女人正抖落伞上的水珠我转头看向另一边他们亲吻对方装着没有注意他们我倒了些牛奶打开报纸有篇关于一个演员的文章在他饮酒时死去不过是某个人物罢了我开始看星象栏目寻找有趣的东西突然感觉有人在注视我于是抬起头外面有个女人正看向里面她看见我了么？

Further,we findalso that groups in Saito's results may be replaced by right groups;secondly we mainly investigatethe semidirect products and wreath products of P-regular semigroups;Finally we shallcharacterize the sandwich matrice of completely simple P-regular semigroups,and investigate thestructure of P-regular semigroup whose C-set satisfies a permutation identity.
