parity violation

基本解释

Nature does seem to have a slight preference for matter, still: a violation of so-called charge-parity (CP) symmetry that has been experimentally verified many times in the lab.
大自然似乎至今对物质都略显偏爱：违反所谓CP对称的现象多次在实验室中被证实。
Researchers have discovered an asymmetry between the behavior of matter and of antimatter, called charge–parity violation, which could have skewed things to our side of the material world.
研究人员已经在物质和反物质的性质之间发现了一种不对称，称之为电荷宇称不守恒，可能已经让事物的演化偏向了我们的物质世界这一边。

Parity violation, as this phenomenon is called, came as a shock to theorists, but they were able to compensate for it by incorporating the effects of electric charge into their models.
