If such a symmetry is indeed found, the question could still be raised whether there could not exist corresponding elementary particles exhibiting opposite symmetry, such that in the broader sense there will still be overall right-left symmetry 如果发现了这种不对称,那么我们又要问,是否相 应地还存在着另一种表象相反不对称的基本粒子行为,从而在 更广泛的意义上,仍然保持着总的左右对称。 李政道,杨振宁 他血 1919 “If such a symmetry is indeed found, the question could still be raised whether there could not exist corresponding elementary particles exhibiting opposite symmetry ,such that in the broader sense there will still be overall right –left symmetry.” “如果发现了这种不对称，那么我们又要问，是否相 应地还存在着另一种表象相反不对称的基本粒子行为，从而在 更广泛的意义上，仍然保持着总的左右对称。 ” --------李政道，杨振宁
