摘　　要：We propose an exactly solvable method to study the coherent two-colour photoassociation of an atomic Bose- Einstein condensate, by linearizing the bilinear atom-molecule coupling, which allows us to conveniently probe the quantum dynamics and statistics of the system. By preparing different initial states of the atomic condensate, we can observe very different quantum statistical properties of the system by exactly calculating the quadrature- squeezed and mode-correlated functions.我们建议一个确切可解决的方法学习原子Bose爱因斯坦冷凝物的协调 two-colourphotoassociation ，由线性化双线性的 atom-moleculecoupling ，它允许我们方便地探查量动力学和准备原子冷凝物的不同起始的状态的 system.By 的统计，我们能很观察 differentquantum 由确切计算压榨照的 相关andmode 的功能的系统的统计性质。
