摘要
在有关文献所提出的距离函数基础上,改进为定点到光滑紧致曲面关于坐标邻域的切空间集的离差函数,利用它可结合曲面点的分类讨论该函数的临界切点及退化情形,得到有关定理及推论,蕴涵了有关文献中相应的结论,并指出定点选择的几何意义.
In this paper a new metric function is presented.With this function,we discuss the critical tangent points of this function and degenerative one,and extend the relative results in paper of LIU Ru-yan.The geometry meaning for the choice of fixed points indicated.
