摘　　要：我们提出一个把未知的两个三能级粒子纠缠态传送给两个接收者的方案,该方案使用一个未知的五个三能级粒子纠缠态作为量子通道。必须指出该方案能够推广到传送未知的N个三能级粒子纠缠态给M个接收者的情况,使用的是未知(N.M+1)个三能级粒子纠缠态作为量子通道。在传送过程中,需要执行适当的幺正操作和(N.M+1)次独立测量,而且该方案不涉及Bell态测量。This paper shows a proposal for the teleportation of an unknown two-particle three-level entangled state to two receivers that are spatially separated using an unknown five-particle three-level entangled stale as the quantum channel. What must be emphasized is that the proposal can be extended to teleport an unknown N-particle three-level entangled state to M reeeivers using an unknown （ N · M ＋ 1 ） -particle three-level entangled slate as lhe quanlum channel at the cosl of performing appropriate unitary transformations and （N · M ＋ 1 ） separate measurement. This proposal doesn＇t concern nilh Bell-state measurements.
