(a)–(d) The influence of λ on the width of the soliton and the center position of the soliton; the values of λ respectively are (a) 1/10, (b) 1/5, (c) 1/3, (d) 1/2. Other parameters are ζ₁ = ζ₂ = ζ₃ = 1, k = 1. (e) The soliton amplitude |u₁|² varies with x for different λ at t = 11.25. Panel (f) is the central position of soliton changing with λ.
