论文摘要
我们使用正常曲线提供了表面分类定理的简单证明。该证明类似于奈瑟（Kneser）和米尔诺（Milnor）的证明，证明了3个manifolds的主要分解的存在和独特性。特别是，我们不需要来自代数拓扑的任何不变性来区分表面。
We present a simple proof of the surface classification theorem using normal curves. This proof is analogous to Kneser's and Milnor's proof of the existence and uniqueness of the prime decomposition of 3-manifolds. In particular, we do not need any invariants from algebraic topology to distinguish surfaces.
