The main research work of this dissertation is as follows: Based on the chemical reaction engineering theory and the nitrobenzene electroreduction mechanism, the plate and frame electrolyzer was designed and applied to the process of electroreduction nitrobenzene to p-aminophenol. This dissertation measured the residence time distribution data of the electrolyzer by means of the pulse response method and studied the rule of flow pattern along with the current capacity change. Under different conditions ,this dissertation studied the cyclic voltammetry properties of nitrobenzene on different electrodes by means of the dynamic cyclic voltammetry method and the electrode materials applied to the NB electroreduction have been selected primarily.Baseed on the results of cyclic voltammetry tests, this dissertation used p-electrode systems to measure the steady-state- polarization curves of nitrobenzene on different electrodes in H-type diaphragm cell, and obtained each primary factor s influence rule and the exchange current density value of each electrode.And then on the basis of the conclusions of fundamental researchs upword, the effects of influence factors on the the yield of p-aminophenol and the current efficiency,such as electrode material, current density, quantity of electricity circulated, nitrobenzene concentration . sulpuric acid concentration and so on, have been studied in detail in the systems of hign temperature , strong acidity and oxygen-poorthrough a series of electrolysis experiments in this paper.After all using Pb as anode Monel metal as cathode Dupont Nafion 417 cation-exchange membrane as membrane, this dissertation obtained the optimum technological condition: reaction temperature about 85C, current density 500A m-2, sulphuric acid concentration 20%wt.

The author explicates some developing aspects in the field of IC industry as suggested areas of future work. The original points of this dissertation are as following: 1. In this dissertation, we got the quality learning curve of China's IC manufacturers by regression. On the base of questionnaire, we later explained the reason of the reverse S type quality learning curve and the tendency of change in quality learning curve. 2. The evolution of technical unit of China's IC industry is calculated in this dissertation. We also explained the reason of technical unit splitting in the way of economic and technology. 3. In this dissertation, we described the environment difference in capital, technology transfer, human resource and market in USA, Japan, Korea, Taiwan and China, and gave some suggestions on the government's role in the development of China's IC industry.. 4. In this dissertation, we established an SD model of China's IC industry, and by using this model, we got some suggestions for future development in China's IC industry.

本文的主要创新之处在于：（1）用回归分析方法实证研究了我国集成电路企业的质量学习曲线，并在调查分析的基础上，对反S型质量学习曲线的历史成因和未来走势进行了研究；（2）对世界及我国集成电路产业技术单元的变化趋势进行了定量研究，从经济和技术角度解释了当前集成电路产业技术单元细化的原因；（3）从资金、技术、人才、市场角度系统总结研究了发达国家在集成电路产业发展环境建设中的成功经验，并结合我国集成电路产业发展的实际情况，对我国集成电路产业发展的政府行为提出了一些建议；（4）建立了狭义集成电路产业、材料业、设备业发展的系统动态模型，并利用该模型对不同投资结构下我国集成电路产业系统未来的演变进行了模拟研究，这一研究结果可以为我国集成电路产业今后发展提供一定的决策依据。

The dissertation gives a omnifarious textual research into Jiujiang"s economy from the all and the one of Jiujiang and the drainage areas of Yangtse River ,synthetically using the methods of history , intercity science , economics , geography and sociology .This dissertation also goes deep into the conventional function and the switchover of its neoteric role,demonstrating the bidirectional nexus between the inland areas of Jiangxi and Yangtse"s entrepot,based on the angle of the center of Jiujiang"s economic noumenon. It probes into the vicissitude from center to verge in the aspect of Jiujiang"s trade. Eventually This dissertation opens out the incompleteness in the course of the neoteric switchover ,based upon the pectination of Jiujiang"s neoteric switchover in the aspects of economic counterchange , urbanoid development and thesocial flux.This dissertation thoroughly delves the typologic significance of Jiujiang"s economic noumenon in the course of the modern switchover of Chinese cities.

全文综合运用历史学、城市学、经济学、社会学等有关理论和方法，将九江与其所处的江西腹地和长江流域作为一个整体进行了多方位的考察，深入探讨了九江社会的传统功能与近代角色的转换；论证了九江以内外贸易为纽带，与江西内腹地区以及长江贸易中心城市之间互补互动的双向关系；剖析了九江从中心到边缘的变换历程；最后，以九江城市为基点，从经济转型、城市发展、城市社会变迁等方面对九江近代社会的转型进行梳理，揭示了九江近代转型不完整性这一基本特征，进而探讨了九江在中国城市近代转型中所具有的类型学意义。
