摘要
依据经典微分几何空间曲线的基本理论与特征,采用三维欧氏空间中曲线的Frenet标架,对三维欧式空间中的一类特殊曲线进行研究,得到了在三维空间下的贝特朗曲线的系列结论,最后讨论了贝特朗曲线与圆柱螺线的关系.
Based on the classical differential geometry space curve of the basic theory and characteristics, the three dimen- sional Euclidean space, the series of conclusions of the three dimensional space of Bertramd' s curve are made through the study of a kind of special curves of the Frenet frame 3 D European space. Finally there was a discussion over the relationship between Bertramd' s curve and cylindrical spiral.
