我们推导出了任意维混合二分量子态的并发的下界。作为推论，一个较弱的，纯粹的代数估计，发现，检测混合纠缠态的一个积极的部分转置。
We derive a lower bound for the concurrence of mixed bipartite quantum states, valid in arbitrary dimensions. As a corollary, a weaker, purely algebraic estimate is found, which detects mixed entangled states with a positive partial transpose.
