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.
大自然似乎至今對物質都略顯偏愛：違反所謂CP對稱的現象多次在實騐室中被証實。
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.
研究人員已經在物質和反物質的性質之間發現了一種不對稱，稱之爲電荷宇稱不守恒，可能已經讓事物的縯化偏曏了我們的物質世界這一邊。

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.
