英文摘要: Inclusive bottom hadron decays are analyzed based on the heavy quark effective field theory (HQEFT). Special attentions in this paper are paid to the b --> u transitions and nonspectator effects. As a consequence, the CKM quark mixing matrix Elements \V-ub\ and \V-cb\ are reliably extracted from the inclusive semileptonic decays B --> X(u)e nu and B --> X(c)e nu. Various observables, such as the semileptonic branch ratio B-SL, the lifetime differences among B-, B-0, B-s and Lambda (b) hadrons, the charm counting n(c), are predicted and found to be consistent with the present experimental data.
