在微扰QCD框架下，利用六夸克图方案及低能有效哈米顿，对于两体赝标介子末态，给出了诱导B介子无璨弱衰变过程的不同费曼图的计算。
Starting from the six-quark-diagram scheme and low energy effective Hamiltonian , we calculate the various Feynman diagrams in the charmless hadronic B-meson decays for the two body pseudoscalar meson final states within the framework of perturbative QCD .
