摘要
给出一般正交标架下H 变形曲面判别的充要条件,并由此得到等温坐标下的表达式.应用此结论,给出Cartan定理"H 变形曲面一定是W 曲面"的一个比较简单的证明.
The new necessary and sufficient conditions of the Hdeformable surface in field of orthonormal frame are given. By this result, an expression of these conditions in an isothermal surface is obtained and the Cartan theorem is proved anew with an easier method.
