The influence of ζ_j on soliton amplitude. (a)–(c) The soliton evolution figures of three chains with ζ₁ = 1, ζ₂ = 2, and ζ₃ = 3. (d) The soliton amplitude evolution over time of panels (a)–(c) at x = −1.2. (e) Soliton amplitude of |u₁|² varies with x for different ζ_j at t = 11.05. (f) The amplitude of soliton varies with ζ₁ at ζ₂ = 1, ζ₃ = 1. Other parameters are λ = 0.2, k = 1.
