摘　　要：应用Hamilton函数由时空变换的不变性,导出动量守恒、角动量守恒和能量守恒定律,说明3个守恒定律是时空对称性的表现,从而阐明3个守恒定律的物理根源和本质。Using the invariance of space-time transformation of Hamiltonian, laws ofconservation of momentum, angular momentum and energy are deduced. It is explained that those three conservation laws are the embodies of space-time symmetry. Therefore, the physicalorigin and nature of these three conservation laws are clarified.

关 键 词：对称性 守恒定律 HAMILTON函数 时空变换
