Abstract：
The CP violating effects in partial-decay-rate asymmetries of the Bd0 and Bs0 systems are reestimated with the method of amplitude ratio. We concentrate on those hadronic final states which are CP eigenstates. We find that for testing CP violations,except the well known Bd0→ψKs, the best decay is Bd0→D⁺D^－, which needs, for 3σ signature, 2.2×10⁷ bb pairs.
