对称性和守恒定律论文物理论文.doc

摘要：近代物理学中的重要观念。如果运动规律具有一种对称性，必相应地存在一条守恒定律。对称变换与守恒量对时空对称性导致动量、角动量、能量守恒作了详细分析，并给出了现在物理学中一些重要的对称性和守恒律的简介。
（The importance of modern physics concepts. If the movement has a symmetry, there will be a corresponding conservation law. Symmetry transform and conserved quantities of space-time symmetry lead to momentum, angular momentum, made a detailed analysis of conservation of energy, and gives some important physics is the symmetry and conservation laws was introduced.）
