摘要：

Nonperturbative corrections up to m(b)-2 to the heavy lepton energy distributions are investigated in the inclusive semileptonic weak decays of heavy flavors in QCD. In the case of B-meson decays, for b --> utaunuBAR transitions they decrease the decay rate by 6% of its perturbative value, while for b --> crnuBAR they decrease it by 10%.
