摘要
In this Letter, we investigate two nonlinear equations given by u(t) - u(xxt) + 3u(2)u(x) = 2u(x)u(xx) + uu(xxx) and u(t) - u(xxt) + 4u(2)u(x) = 3u(x)u(xx) + uu(xxx). Through some special phase orbits we obtain four new exact solutions for each equation above. Some previous results are extended.
