Abstract：
CP-violating effects in partial-decay-decay-rate asymmetries for two-body baryonic decays of B⁰－B⁰ and B⁰－B⁰ systems are examined.We concentrate on those final states into which both B⁰ and B⁰ can decay.Two cases are discussed in detail:one is for Z⁰ factory 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 B⁰→PP,Δ⁺⁺Δ^－－ and Δ⁰Δ⁰,N_bb～10⁷—10⁸.
