摘要：
The nonlocal conservation laws for the N = 1 supersymmetric KdV equation are shown to be related in a simple way to powers of the fourth root of its Lax operator. This provides a direct link between the supersymmetry invariance and the existence of nonlocal conservation laws. It is also shown that nonlocal conservation laws exist for the two integrable N = 2 supersymmetric KdV equations whose recursion operator is known.
