On the History of the Discovery of Parity Nonconservation and the Lee-Yang s Argument——In Commemoration of the 50th Anniversary of the Discovery of Parity Nonconservation;

She firstly confirmed the theoretical assump- tion of parity nonconservation in weak interaction that proposed by Yang Chen-ning and Lee Tsung-Dao.

According to the chirality of the weak charge the origin of parity nonconservation in the weak interactions is reasonably explained.

Assuming Higgs Assuming coupling to be the only origin of parity non-conservation, an SU(3)c ×SU(2)1×U(1)Y theory of composite leptons is established in the Scheme of three generations and supersymmetry.

On the basis of Adolf Grünbaum refute logically Duhem-Quine Thesis and experiment analysis about Parity non-conservation, this paper conclude from specific science practice what experiment can refute decisively theory.

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.

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

This paper is concerned with the research into the logical auto-agreement between the inverse transformation of matrix and the reversibility of ray in Matrix Optics,reveals the unity between the abstract performance of matrix and the actual physical process,and maintains lastly that their unity is based on the conservation of parity of the macroscale physical phenomenon.
