We find that in the set of tripartite entangled state except for GHZ state, the peculiar tripartite entangled states have three-way entangled as GHZ state and two-way entangled as W state simultaneously.

• 在我们制备的三粒子纠缠态集中,除了那些和GHZ态LU等价的态外,还有一些三粒子纠缠态具有特别的纠缠特性,既象GHZ态一样具有三部分纠缠,同时又象W态一样具有两部分纠缠,且任何两部分是否纠缠及纠缠强度可以独立地按照我们的需要来调制。
