    A scheme of teleportation of a N-particle entangled GHZ state through a two-paticle entangled quantum channel was proposed. Firstly, the maximally entangled states were taken as quantum channels, then the case of nonmaximally entangled channels was considered. It was found that by implementing H transformation and von Neumann measurement, introducing an ancilly qubit, when the channels are nonmaxially entangled states, constructing an unitary transformation properly, teleportation of three-paticle entangled GHZ state cound be implemented with certain probability. Finally, the N-particle entangled GHZ state was discussed. Compared with other schemes, this scheme saves the quantum entanglement channel resources.
