摘 要: 运用动力系统的几何理论、分支理论及大量的积分运算,求出了Rangwala Rao方程的型如u(x,t)=ei(φ(ξ)-ωt)a(ξ),ξ=x-vt的5种显式精确孤波解.本文包含了以往文献所得的结果,且给出了若干新解. By using the qualitative theory and bifurcation theory of planar dynamical systems, five kinds of the explicit exact solutions of solitary waves in the explicit form of e^i(φ(ε)-ωt)a(ξ), ξ=x-vt, are obtained. The results in the paper improve all of the relative results, moreover several more explicit exact solitary wave solutions are obtained.
