This paper consists of three parts:We first consider the non-autonomous predator-prey system with both Beddirigton-DeAngelis functional response and dispersion. By using comparison theorem of differential equation, we study the permanance of the system. After that, by constructing suitable Lyapunov function, we obtain some sufficient condition which guarantee the existence of globally asymptotically stable almost periodic solution of the system.

On the basis of the dispersion relation, we investigated the properties of nonlinear surface waves. It is shown that there exist backward surface waves, with the phase velocity and group velocity opposite in direction. For transverse electric waves, the nonlinear wave equation is transformed into Bernoulli equation, and the exact solutions of magnetic fields are obtained.
