摘要:根据文献[ 1]所讨论的有关问题, 建立一个二元函数, 用于讨论该函数的临界切点及蜕化情形, 结合曲面点的分类得到有关定理及推论,改进并推广文献[ 1]中相应的结论.

关键词: 临界切点, 蜕化临界切点, 临界点

Abstract: In this paper a new two element function is developed based on the properties of paper [ 1] . With this, we discuss the critical tangent points of this function. The theorems and corollarys in this paper are improvements and extensions of the related conclusions of [ 1] , depending on the C2 class surface point's classification.

Key words: critical tangent point, degenerative critical tangent point, critical point
