摘要
本文主要介绍了经典包络理论的产生背景,并且介绍了如何求二维空间中的一族曲线的包络曲线以及三维空间中含两个参数的曲面族的包络面,并说明了包络理论与重整化群方法之间的关系。
This paper mainly introduces the background of the classical envelope theory.And describes how to find the envelope curve of a family of curves in two dimensional space,And the enveloping surface of the curved surface with two parameters in three dimensional space.And the relationship between the envelope theory and the method of renormalization group is also explained.
