摘　　要：求曲线尹={cos^3t,sin^3t,cos2t}的曲率、挠率一般做法通过套用曲率、挠率公式，而本文追根溯源，利用Frenet公式求曲线的曲率、挠率，同时探讨了曲线的相关结论。The common practices to detect the curvature and torsion of the curve r ={cos^3t,sin^3t,cos2t} is to use the formulate of the curvature and torsion. This paper traces the origins, by using the formula Frenet to detect the curvature and torsion of the curve. Meanwhile, it discusses some related conclusions of the curve.
