Abstract：
CP-violating effects in partial-decay-decay-rate asymmetries for two-body baryonic decays of B ⁰－B ⁰and B ⁰－B ⁰systems are examined.We concentrate on those final states into which both B ⁰and B ⁰can decay.Two cases are discussed in detail:one is for Z ⁰factory for incoherent BB production,the other is for C=+1 BB production above the Υ(4S) resonance at symmetric colliders.The bb pairs needed for testing these effects are estimated for 3σ signature.For the decay modes B ⁰→PP,Δ ⁺⁺Δ ^－－and Δ ⁰Δ ⁰,N _bb～10 ⁷—10 ⁸.
