Abstract:	In the framework of the heavy-quark effective theory, theO (O(_QCD)) corrections are estimated in the test of factorization hypothesis forB-meson nonleptonic decays proposed by Bjorken. Similar calculations are also carried out for _b nonleptonic decays. The effects of these corrections on the estimate of theD_s-meson decay constant are discussed.
