变动端点变分问题的三维空间横截条件及其统一证明

摘要

借助于二维空间中变动端点的变分问题，对三维空间中变动端点变分问题的横截条件做了统一的推导和证明。%This paper intends to discuss three-dimensional spatial transversality condition for the varial-tional problem of variable endpoint and its unifying proof through the way of the varialtional problem of variable endpoint in two-dimensional space.
