摘要：
An isospectral problem is established by means of a sub-algebra of loop Lie algebra (A) over tilde (1), from which the coupled AKNS-Kaup-Newell soliton hierarchy is derived. Subsequently, the integrable expanding model, i.e. integrable coupling, is constructed through enlarging the corresponding loop algebra into the loop Lie algebra (A) over tilde (2).
