摘要：
In this paper, based on the KP hierarchy reduction method, we get the concrete form of semi-rational solutions to the Hirota-Maccari (HM) system. The semi-rational solutions describe a variety of solution types, such as lumps, breathers and line solitons. In addition, we simplify the representation of the higher-order semi-rational solutions of the HM equation and focus on the lump classification as well as the dynamics of mixed solutions about lumps and line solitons. Simultaneously, the modulation instability of the HM equation is also analyzed. The kinetics of semi-rational solutions for the HM system are subsequently discussed.
