To fulfill the need of the application of RP technique in medical domain, reverse CAD modeling from medical cross sections is systematically studied in this dissertation. Firstly, Some algorithms related to the research of this dissertation are studied. New algorithms for orientation and inclusion test for simple polygon, an error constrained automatic faring algorithm for B-spline curve and a theorem regarding the termination criterion for subdivision of triangular Bézier patch are proposed. Then based on similarity between contours of adjacent sections, a methodology for surface reconstruction from cross sections is presented. Finally, a virtual measuring method is proposed.

本文针对RP技术在医学领域应用的需要，系统研究了基于医学断层轮廓数据的反求CAD建模理论和方法：(1)在基础算法研究部分，提出了简单多边形方向及点在多边形内外判断的新方法、三角Bézier曲面片离散的误差控制定理和一种带误差约束的B样条曲线的自动光顺方法；(2)提出了一种基于相邻层轮廓相似性的医学断层轮廓数据曲面重构方法；(3)提出了一种称为"虚拟测量"的曲面模型处理方法。

For the capacity of propeller turbine is often small, people pay little importance on the transformation of reducing capacity under specified conditions. So, nowadays little research mentioned above has been developed.For the particularity of the designed factors, the author has improved the traditional theory, and has fined an available Method of singular point distribution. At present, no one has developed CAD hydraulic design software of lower specific speed axial flow runner in our country.

由于设计条件的特殊性，在研究设计方法过程中，论文基于传统设计理论，对引用的一些基本规律做了一定改进，在具体设计过程中，对经验参数的选择方法做了一定探索，研究与探索运用奇点分布法设计低比转速轴流式转轮叶片；传统的设计工作全部由人工完成，无法满足当今社会科技生产发展的需要，因此论文开发了一套具有人机对话界面良好特点的低比转速轴流式转轮CAD软件。
