摘要
本文从哈密顿变分原理（以下简称哈密顿原理）出发，讨论当一个系统存在某种对称性时，哈密顿原理便可给出此系统存在一个守恒量。同时指出，由于哈密顿原理与座标选择无关，它不仅深刻地揭示出宏观机械运动的统一，而且可以无困难地直接搬到量子领域，使我们能够获得关于物理问题中守恒律的非常一般的信息。
Based on Hamilton's variational principle,this peper proves that,for a system which is symmetric to some transformation there must be a conservative quantity. It is pointed out that Hamilton's principle reveals the unity of macraseopic mechanical movement as it is not related to the selection of coordinates,and can also be applied to the quantum physics,thus enables us to obtain general information abour the law of conservation in physics.
