All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

Second, there are four Chapters of this paper: Chapter I Russian History and the fate of intellectual in the 20thcentury, which unscrambles the very historical context reflected by Doctor Zhivago. It refers to the changes of Russian history and politics, the fate of Russian intellectual, the living condition of Pasternak in the torrent times. Chapter II The choice of fate by Russian intellectuals, specificly analyses different choices by different intellectuals, in order to prominent truly noble character of Russianintellectuals; ChapterⅢThe spiritual confusion of Russian intellectuals, analyses the basic formation of their spiritual confusion in the 20th century context of Russian History. It refers to the disjunction between reality and ideal, the tragedy of Hamlet-like character, and Zhivago-like spiritual orphan of Jew. Chapter IV The spiritual remolding of the Russian intellectuals, which profoundly analyzes the relationship among Tolstoyism, Christian faith and belief of the humanitarianism on the blue print of Doctor Zhivago's spiritual experiences, therefore, reflects the tropism of humanitarian value of Russia in the 20th century.

其次,正文部分共分四章:第一章&20世纪俄罗斯历史与知识分子的命运&,主要是从20世纪俄罗斯历史与政治变革、20世纪俄罗斯知识分子的命运、处在时代漩涡中的帕斯捷尔纳克的生存境遇等方面,来(来源:6a6aAB5eC论文网www.abclunwen.com)解读《日瓦戈医生》所反映的特定历史语境;第二章&俄罗斯知识分子的命运选择&,通过具体分析在特定的历史语境中,俄罗斯不同类型的知识分子对于命运的不同选择,以突出真正的俄罗斯知识分子高贵的人格品质;第三章&俄罗斯知识分子的精神困惑&,从理想与现实的脱节、&哈姆雷特式&的性格悲剧、日瓦戈式的&犹太精神孤儿&等方面,具体分析了20世纪俄罗斯历史语境中知识分子精神迷茫的基本形态;第四章&俄罗斯知识分子的精神重塑&,以日瓦戈医生的精神历练为蓝本,对20世纪俄罗斯知识分子的精神重塑与托尔斯泰主义、基督教信仰以及对人道主义的崇信的内在关系做了深刻解剖,从而折射出20世纪俄罗斯社会的人文价值取向。

The effects of solution\'s pH value, mol ratio between phenyl aldehyde and L-Arginine, concentrations of sodium chloride, ammonia chloride andL-Lystine, initial concentration of L-Arginine on precipitation rate of a -tolylene arginine were investigated, the results indicated that phenyl aldehyde precipitation method\'s appropriate pH value was higher than 11, suitable mol ratio between phenyl aldehyde and L-Arginine was 1.25, initial concentration of L-Arginine was must higher than 15g/L, sodium chloride had little effect on precipitation rate, on the contrary, ammonia chloride and L-Lystine had great effect on it, both of them must be eliminated; At the same time, adsorption isotherm at 25 C of L-Lystine on anion exchange resin A was measured, the result showed that the maximal equilibrium adsorbance was 30mg/g, the influences of solution\'s pH value, temperature, concentration of chloride ion on adsorption of L-Lystine by anion exchange resin A were also studied, the results indicated that appropriate operational pH value was 0.5 0.2, the effect of temperature on adsorption ratio was little, process could be operated at room temperature, the concentration of chloride ion must be eliminated.

考察了溶液pH值、苯甲醛与L-精氨酸摩尔比、氯化钠与氯化铵浓度、L-赖氨酸浓度、L-精氨酸初始浓度对苯甲醛沉淀L-精氨酸的影响,结果表明,沉淀反应的适宜pH值大于11,苯甲醛与L-精氨酸的适宜摩尔比为1.25,(来源:Aa6BC论文网www.abclunwen.com)L-精氨酸适宜的初始浓度在15g/L以上,氯化钠的存在对沉淀率基本上没有影响,而氯化铵和L-赖氨酸的存在使沉淀率下降;同时测定了25℃时阴离子交换树脂A吸附L-赖氨酸的吸附等温线,表明其最大平衡吸附量为30mg/g,考察了溶液pH值、温度、氯离子浓度对阴离子交换树脂A吸附脱除L-赖氨酸的影响,结果显示从L-精氨酸和L-赖氨酸混合液中吸附分离出L-赖氨酸的适宜pH值为10.5±0.2,温度对L-赖氨酸吸附率影响不大,吸附过程可在室温下进行,氯离子的存在使L-赖氨酸的吸附率降低。
