摘　　要：利用海森堡不确定关系和薛定谔-罗伯逊不确定关系推导高阶两粒子多模的分离判据条件.通过比较由两种不确定关系得到纠缠判据条件,发现利用薛定谔-罗伯逊不确定关系进行推导,能得到更强的分离判据条件.The separation discrimination conditions of higher-order two-particle multiple mode were de- rived by using Heisenberg and Schri^dinger-Robertson uncertainty relations. After comparing these two uncertainty relations, the entanglement discrimination conditions were obtained. It was found that a stron- ger separation discrimination condition could be obtained based Qn the derivation with Schrodinger-Robert- son uncertain relation.
