给出了一个更简单的判据来判断W态是否可以作为量子信道来实现对任意单量子比特态的完全分裂或隐形传输。在W态可用的情况下，充分展示了两个量子信息过程中的具体操作。此外，还进行了相关的讨论。
A simpler criterion is presented to judge whether a W state can be taken as quantum channel for perfectly splitting or teleporting an arbitrary single-qubit state. If the W state is usable, the detailed manipulations in the two quantum information processes are amply shown. Moreover, some relevant discussions are made.
