failure of parity conservation,parity violation

Discovery of non-conservation of parity is an important event in the development history of physics.

宇称不守恒的发现是物理学发展史上的一个重大事件。

20 century began from the research of symmetry,the discovery of nonconservation of parity starts epoch of research of breaking symmetry.

20世纪开始于对称性研究,宇称不守恒开创了研究对称破缺的新纪元。

In this paper, we discussed the transition selection rule of electrical dipole radiation in atom physics by the parity theory and angular momentum theory in quantum.

本文利用量子力学的宇称理论和角动量理论，对原子物理学中所熟知的电偶极辐射的跃迁选择定则进行了理论探讨。

The author analyses the differences and relationships between Dirac s equation and 2-Component neutrino theory, then shows that experment of polarzed C_o￣(60) has not overthrown the law of parity conservation.

文中分析了狄拉克方程与二分量中微子理论的区别和联系，证明了极化Ｃｏ６０等实验并未推翻宇称守恒定律。

It is shown that parity conservation is verified for the Hamiltonian system operatorwith inversion space invariance for the case u(-x)=-u(x).

当u(x)是奇函数时,体系的哈密顿算符^H具有空间反演不变性,宇称守恒。
