三维欧氏空间中的渐近曲线是局部微分几何中的一种重要的曲线 ,它有许多重要的性质和应用 ,这些在一般的教科书上都有介绍。
In Minkowski space R~(3,1) by employing the method of moving frames to describe construcions and to make local calculations,the equations about asymptotic direction and asymptotic curve of spacelike surface are obtained,and some corresponding results obtained before are extended and improved.
考虑Minkowski空间R3,1中类空曲面的渐近方向与渐近曲线,采用活动标架的方法进行局部计算和整体结构的刻画,得到了渐近方向与渐近曲线的一般方程,推广并改进了已有的结果,并通过具体例子加以阐述。
In this paper,we discuss parallel surfaces of a surface and obtain the sufficient and necessary condition for geodesic (asymptotic curve) of the surface whose corresponding curve is geodesic(asymptotic one) of the parallel surface.
