Starting from bilinear form of integrable models, one can obtain a dromion solution that is localized in all directions or a “Solitoff” solution that decays exponentially in all directions except a preferred one for the physical field or a suitable potential. The interactions between dromions, dromion and “Solitoff”, solitons are studied in detail through the method of figure analysis for two KdV type equations. Some interactive properties between two dromions (solitons) are revealed for two models. The interactions between two dromions(solitions) may be elastic or inelastic for different form of solutions.
