A scheme of teleportation of a three-particle entangled GHZ state through a two-paticle entangled quantum channels
is proposed. the two-particle nonmaximally entangled state is taken as quantum channels, We find that by implementing
H transformation and von Neumann measurement,introducing an ancilly qubit, constructing an unitary transformation
properly, teleportation of three-paticle entangled GHZ state can be implemented with certain probability. This scheme
saves the quantum entanglement channel resources comparing with other shemes.
