| 摘 要： | 在单量子系统中，利用相干度量的定义及其性质，基于不同相干度量分别研究纯态和混合态的态排序，并给出Cmax,Cv-max与Cr,CI,Cl1的态排序结果.结果表明：Cr,CΙ,CH对纯态提供相同的态排序，该态排序结果对混合态不成立；不同于纠缠度量，2个相干度量在纯态中的序关系对任意态未必有相同结果.

| Abstract: | By using the definition and properties of the coherence measure, we studied the state ordering of the pure state and the mixed state respectively in a single quantum system, and gave the state ordering results between Cmax,Cvmax and Cr,CI,Cl1 The results show that Cr,CΙ, and CH provide the same state ordering for pure states, but this state ordering result is not formed for mixed states. Unlike entanglement measures, the order relationship between two coherence measures in a pure state may not necessarily have the same result for any state. |
