In general, the design work with traditional measures is done by hand, which cannot meet the needs of the technology and manufacture. So the author has developed a CAD hydraulic design software fit for lower specific speed axial flow runner, which is easily operated by users.The main research work of this paper is as follows:1 Analyzing the main reason of axial flow power station cannot work well under littler volume of flow in some season and putting forward an improving scheme, pointing out the characters of design under abnormal factors.2 Combined with the development of the industry in our country, the abnormal hydraulic design method of propeller turbine is discussed based on present literature, data and experiment results.3 Guided by the design method of software engineering, a suit of hydraulic design software of Lower Specific Speed Axial Flow Runner is programmed by the object-oriented programming language Visual Basic and a straightforward, concise and standard Windows human-computer dialogue interface is designed for the system, which makes the operation of the system very convenient.4 ActiveX Automation technology is adopted as the interface with AutoCAD and the hydraulic drawings are edited, modified by AutoCAD until hydraulic model drawings according with the demand of engineering practice are output.5 To resolve practice problem, the author has designed a lower specific speed axial flow runner for Duowa Power Station through an example.

论文的主要内容有：1 深入分析很多轴流定桨式水电站枯水季节小流量下不能发电的主要原因，提出减容改造方案，并指出超常规条件下的改造设计特点。2 结合国情及行业发展需要，参考现有资料、文献和前人的研究成果，进行低比转速轴流式转轮叶片水力设计方法的研究，对轴流式转轮叶片的奇点分布法水力设计进行了全面的探索，结合现代计算机技术，找到了一种针对特殊条件的轴流式转轮叶片水力设计方法。3 仔细比较多种AutoCAD二次开发工具后，结合本课题的特点，选用Visual Basic语言，综合应用软件工程的设计思想，进行低比转速轴流式转轮叶片水力设计软件的编制，为系统设计了直观、简洁和标准的Windows人机对话界面，便于用户操作；编程时在考虑到设计条件特殊性的同时，尽量做到程序的通用性，使之可用于解决同一类问题；另外，大部分程序还可移植到普通轴流式转轮叶片水力设计中，具有良好的适应性。4 利用ActiveX Automation技术与AutoCAD接口，对AutoCAD进行二次开发，在AutoCAD下实现水力图的自动生成和编辑，直至输出符合实际工程要求的木模图。5 通过算例，为多哇水电站设计了一个低比转速轴流定桨式转轮，解决其在枯水期小流量下不能发电的问题。

The present thesis adopts Iseult Honohan's six basic elements of republicanism as a theoretical framework for the study of Jefferson's conception of republicanism, which is the theoretical basis of his conception of the ward system:(1) Jefferson's conception of virtue, characterized by his optimism about the universality of the moral sense and the people's capacity of self-government;(2) Jefferson's conception of freedom, characterized by his synthesis of both negative liberty and positive liberty;(3) Jefferson's criterion of the republican government and the scope of the republic, characterized by his synthesis of both participation and representation;(4) Jefferson's conception of the shaping of republican citizens, characterized by the synthesis of school education and active participation in public affairs;(5) Jefferson's conception of the material preconditions of the republic, characterized by his primary concern for the economic independence and political freedom of both the individual and the nation.

杰斐逊的共和主义思想是他的分区制度构想的理论基础。论文首先采用Iseult Honohan 的"共和主义基本要素"作为理论框架，从以下五个方面对杰斐逊的共和主义思想进行研究：(1)道德观，主要特点体现为对道德意识的普遍性和人民的自治能力持乐观态度；(2)自由观，主要特点体现为消极自由与积极自由相结合；(3)共和政府的标准以及共和国的范围，主要特点体现为人民直接参政与代议制相结合；(4)塑造共和公民，主要特点体现为学校教育与积极参与公共事务相结合；(5)共和国的经济基础，主要特点体现为对个人与国家的经济独立与政治自由的关注。
