摘要
考虑曲面上法曲率最值和最值方向的直接求法问题,给出了直接的导出方法,并得到了它是特征值、特征向量的性质.
The direct method of finding the extreme value of normal curvature and the extreme value di- rection are considered. A direct derivation method is proposed,and its properties as matrix characteristic value and characteristic vector are obtained.
