Studying the non-leptonicdecay of B meson is an important task in particle physics, and any breakthrough in theory may take new blood to this field.
介子的两体非轻子衰变过程是粒子物理中一个很重要的研究课题，任何理论上的突破都会引起广泛的关注。

Here we study the coefficient of viscosity in mixed phases, calculate the contributions of two kinds of non-leptonic reactions (the non-leptonicdecay of hyperons and quarks).
