中文摘要：

以在状态和它的减少的状态之间的关系，我们获得为在无限维的由两部组成的量系统的所有可分离的状态有效的二不平等。他们之一提供严格地比强壮的一个纠纷标准可计算出来跨标准或重组(CCNR ) 标准。

英文摘要：

In terms of the relation between the state and its reduced states, we obtain two inequalities which are valid for all separable states in infinite-dimensional bipartite quantum systems. One of them provides an entanglement criterion which is strictly stronger than the computable cross-norm or realignment （CCNR） criterion.
