The effects of real and virtual gluon emission are taken into account. Main emphasis is put on the difference of the life-times of B/sub s//sup 0/ mesons with different CP parity. This difference is found to be the largest in the b-family. Possibilities for experimental study of this phenomenon are briefly discussed. 16 refs. (Atomindex citation 18:092417) 收起
