摘　　要：讨论了宇宙早期的CP破坏与超对称性伴子的相互关系,给出了现时夸克、现时轻子与超对称性夸克、轻子因CP破坏而存在的不同结构和相互关联.探讨了超对称反质子B+1与费米型反质子F+1的区别,初步说明了F+1-B+1湮灭不会象F+1F+1湮灭那样全部转化为光子的原因.The correlation between the CP violation in the early universe and supersymmetry companions is discussed, the different structures and the mutual correlation between a present quark and its supersymmetry quark and between a present lepton and its supersymmetry lepton because of CP violation are given. The difference between the supersymmetry antiproton P^＋1B and the antiproton P^＋1F of Fermi type is explored and a preliminary explanation for the reason why the annihilation of P^＋1F P^＋1Bcannot transform into photons completely but that of P^＋1F P^＋1F can is given.
