摘要
应用微分几何、空间解析几何以及画法几何,提出了构成两种典型的直纹渐变曲面管道的简易可行的方法;并以这两种管道为例,对其横断面的变化及函数方程进行了详尽的讨论和分析,对一般直纹渐变曲面也进行了讨论与分析。
An easy way of constructing two kinds of typical ruled-surface transition duct is presented in context of descriptive, analytical and differential geometries in this paper. Taking the two kinds of ducts for example, the variety of its cross-section area and the functional equations are treated in detail. Common ruled-surface transition ducts are also discussed in this paper.
