摘要：
In optics, the Sasa-Satsuma equation can be used to model ultrashort optical pulses. In this paper higher-order soliton solutions for the Sasa-Satsuma equation with zero boundary condition at infinity are analyzed by partial derivative(-) method. The explicit determinant form of a soliton solution which corresponds to a single pl(-)th order pole is given. Besides the interaction related to one simple pole and the other one double pole is considered.
