摘要
本文讨论了三维仿射空间Ａ３中曲面的无穷小等距变形．给出了Ａ３ 中无穷小Ｏ． Ｂｏｎｎｅｔ 等距的定义，得到了曲面允许非平凡的无穷小Ｏ． Ｂｏｎｎｅｔ－等距变形的一个充要条件．．
In this paper we discuss the infinitesimal isometric deformation of surfaces in A 3 , we give the definition of infinitesimal O. Bonnet isometry and obtains the necessary and sufficient condition for surfaces to admit non trivial infinitesimal O. Bonnet isometry.
