英文摘要：

Exact solitary wave solutions for a class of strongly coupled BBM systems are investigated. To find an explicit solitary wave solution of the system,it is sufficient to find a solution of an ordinary differential equation. For a specified form of solutions,the solution of the ordinary differential equation can be found by solving a system of nonlinear algebraic equations. By means of hyperbolic function method,and by detailed computation,the exact solitary wave solutions of the system are presented.
