R1^3中类空曲面的“欧氏”曲率椭圆与副法方向

摘要

In Spacelike surface of Minkowski space R13 by employing the method of moving frames to make local calculations,the definitions and properties about curvature elliptic and vice normal direction are obtained,and some corresponding results also obtainded through extending and improving.%在Minkowski空间R1^3中的类空曲面上,考虑曲率椭圆和副法方向的定义及其性质,采用活动标架的方法进行局部计算和整体结构的刻画,推广并改进了欧氏空间中的已有结果。
