摘要
强相互作用中近似成立的ＳＵ（３）对称性被用来分析美介子半轻子三体和四体衰变，获得了衰变宽度之间的一些ＳＵ（３）联系．这些联系可以为了解美介子半轻子衰变中产生的各种动力学效应的性质提供一些信息．
Based on the SU(3)approximate symmetry in the strong interaction threebody and four-body semileptonic B-meson decays are analyzed.Relations between decay rates are derived.Some of these relations may provide information on the nature of various competing dynamical effects that can occur in semileptonic B-meson decays.
