摘要：

Branching ratios of nonleptonic exclusive two-body decays of B mesons without final-state charm particles are studied in detail. The technique used for evaluating the nonleptonic decay amplitudes is elucidated. The dominant charmless decay channels are (B(u+) --> K+eta', pi+eta',rho+pi-0, rho+eta, rho+eta', rho+omega,B(d)0 --> K0-eta',eta-eta',eta'-eta', K*+pi-,K*+rho-, rho+rho-, which should be interesting for experimental observation. The implications of the quark-diagram scheme are also discussed.
