    When an initial entangled state is transformed into a target entangled state by local operations and classical communication (LOCC), the quantity of entanglement of the initial state decreases. Morikoshi (reference [10]) showed that the entanglement lost in the transformation can be partially recovered by an auxiliary entangled state. However, the entanglement degree of the auxiliary entangled state is required to be larger than that of the target state. This paper shows that the entanglement catalysis can be used to assist the recovery of the entanglement even the entanglement degree of the auxiliary entangled state is less than that of the target state. Some necessary conditions for the entanglement catalysis are also given.
