摘要：
The decay rates of the inclusive semileptonic decay and the inclusive ccsBAR decay of B0 and B+/- mesons via the spectator and W-exchange mechanisms are calculated. By including contributions from both the spectator and W-exchange effects, we obtain a branching ratio of B --> evX that falls within the experimentally allowed region and one for B --> ccsBAR that satisfies the experimental constraint.
