论文摘要
使用凯奇（Cauchy）的方法证明众所周知的欧拉公式是许多争议的对象。本文的目的是证明Cauchy的方法不仅适用于Polyhedra，而且还适用于它们，还适用于它们，还适用于表面，例如Torus，Poxchive Plane，Klein Bottle，Klein Bottle和The Pinched Torus。
The use of Cauchy's method in proving the well-known Euler formula is an object of many controversies. The purpose of this paper is to prove that the Cauchy's method applies for convex polyhedra and not only for them, but also for surfaces such as the torus, the projective plane, the Klein bottle and the pinched torus.
