    本文研究了R3中相交子流形的不变量.利用活动标架法,得出了一个类似的欧拉公式. 即两曲面交线的挠率可以用两曲面的测地挠率、法曲率及两曲面的夹角表示.

    We investigate invariants of the intersection of submanifolds of R3. We obtain an analogue of Euler formula by using the method of moving frames. The torsion of the intersection curve of two surfaces in R3 can be expressed by geodesic torsions,normal curvatures and the angle between surfaces.
