摘要：
The fourth-order equation for description of nonlinear waves is considered. A few variants of this equation are studied. Painleve test is applied to investigate integrability of these equations. We show that all these equations are not integrable, but some exact solutions of these equations exist. Analytic solutions in closed-form of the equations are found. (C) 2015 Elsevier B.V.
