摘要 讨论了Hiroda Satsuma方程rx-rxxt-3rrt+3rx∫∞xrtdx+rt=0和相关的两簇演化方程.利用Darboux变换,求出Hiroda Satsuma方程的一些感兴趣的解(如分杈孤子解、奇异解等). Hiroda-Satsuma equation r_x-r_(xxt)-3rr_t+3r_x∫~∞_xr_tdx +r_t=0  and associated two hierarchies are studied. A Darboux transformation of a spectral problem associated with these equations are considered. Some interesting solutions (such as bifurcate soliton solution, singular solution ) have been found.
