摘要 本文以双曲螺线为背景,生成曲面为研究对象,讨论了三维欧氏空间中双曲螺线的主法线曲面的几何性质.获得了双曲螺线的主法线曲面的渐近曲线、曲率线、法曲率、主曲率、高斯曲率、平均曲率等,并给出了简单应用。 The hyperbolic spiral as the background,surface generation as the research object,discusses the geometric properties of hyperbolic spiral's principal normal surfaces in the Euclidean three- space,hyperbolic spiral's principal normal surfaces of asymptotic curves,curvature method,principal curvature,Gaussian curvature,mean curvature all be obtained in this paper,and gives some simple application.
