摘　　要：　用平面动力系统的方法研究了BBM方程,光滑的孤立波和周期波解的存在性被证明了。在参数平面的不同区域,给出了足够的条件来保证上述解的存在性。在一些条件下,列出了解析的精确孤立波解和周期波解。Using the method of planar dynamical systems to study Benjiamin-Bona-Mahony equation, the existence of smooth solitary wave and periodic wave solutions are proved. In different regions of the parametric plane, the sufficient conditions to guarantee the existence of the above solutions are given. In some simple conditions, exact explicit solitary wave and periodic wave solutions are listed.
