摘要：

It is studied here how the Ablowitz-Ladik (AL) hierarchy and their restricted Bows are related to the AKNS hierarchy and to their restricted Bows in the continuous limit. It is shown that restricted Bows of the AL hierarchy yield discrete maps approximating restricted flows of the AKNS hierarchy. Integrals of motion and Lax representation for restricted Rows of the AL hierarchy as well as a discrete zero-curvature representation for the AL hierarchy with sources are given.
