Because of production cost advantages , china became the world factory . this article also introduced the development course of a most important enterprise in sichuan tv industry 在这样的背景下,本文也介绍了四川彩电产业最重要的一家企业的发展历程(文中以虹宇称之) 。
The pdg discussion of cp violation can be used to supplement the discussion in class , available at cp violation in b decay - standard model predictions ( pdf ) 电荷共轭和宇称破坏的粒子物理资料组讨论可作为课上讨论的补充，在" b介子衰变的电荷共轭和宇称破坏标准模型的预测( pdf )处可得。
Experiments revealed that the decay probabilities of right - spinning and left - spinning cobalt atoms were different . this phenomenon of symmetry breakdown is called the violation of the principle of parity conservation 右旋和左旋的钴获实验证明它们的衰变率并不相同，即所谓宇称不守恒。

According to foreign ministry spokeswoman jiang yu , about 300 overseas chinese , mostly the elderly , women and children , had sought refuge at the local embassy after their homes and business were destroyed 据外交部发言人姜宇称：大约300多位侨胞已向当地大使馆寻求保护，他们已经家破人亡、一无所有，其中大多数是老妇和小孩。
Today , many scientists believe that we are living in a universe made primarily of matter , instead of one comprising equal amounts of matter and anti - matter . this may be attributed to the violation of parity conservation 不少科学家相信我们今天之所以生活在一个主要由物质而非由同等数量的正反物质所组成的宇宙，与此宇称不守恒有莫大关系。

In october 1957 , prof . yang in collaboration with prof . lee tsung dao made significant contributions to the theory of weak interactions by proposing that parity may not be conserved in weak interactions the forces long thought to cause elementary particles to disintegrate 一九五七年十月，他与李政道教授提出弱衰变过程中宇称不守恒的原理，指真实世界与镜子里的影像世界不对称。简而言之，就是说明了左右不对称、不等同。
