Figure 2. A hybrid solution of solitons and a kink obtained by Darboux transformation with $\alpha =2,b=1$: (a) a hybrid solution ${q}_{2-{\rm{kink}}-{\rm{hyb}}}$ of two-soliton and a kink with parameters ${\lambda }_{1}=1-3{\rm{i}},{\lambda }_{2}=3{\rm{i}},{\lambda }_{3}=2{\rm{i}},{\lambda }_{4}={\rm{i}};$ (b) a hybrid solution ${q}_{4-{\rm{kink}}-{\rm{hyb}}}$ of four-soliton and a kink with parameters ${\lambda }_{1}=1-3{\rm{i}},{\lambda }_{2}=3{\rm{i}},{\lambda }_{3}=2{\rm{i}},{\lambda }_{4}={\rm{i}},{\lambda }_{5}=\tfrac{{\rm{i}}}{2},{\lambda }_{6}=\tfrac{{\rm{i}}}{3}$.
