文章主要研究在有限温度下两个比特海森堡XX自旋链中Z方向的Dzyaloshinskii—M0rriya（D—M）相互作用（Dx）和耦合常数（J）对各种量子关联的影响。研究发现在有限温度下不加Dx时经典关联（cc）和量子失协（QD）都随温度的提高而下降，下降速度也比较快。加了Dx时也是随温度的提高而下降，但是下降速度较慢。从计算分析看，在有限温度下Dx和J对QD和CC有积极作用。调整适当的Dx和J参数，可以有效地控制和提高各种量子关联。

This paper mainly investigates the quantum correlation in two bits Heisenberg XX spin chain at finite temperature Z direction with the Dzyaloshinskii-Morriya ( Dx) interaction, the study loud that at the finite temperature the classical correlation and quantum discord decline with the increase of tem- perature, the decline faster, we added the Dx, he classical correlation and quantum discord decline with the increase of temperature,But the decline slower than former. From the computational analysis , we know that D, and J has a positive effect on the concurrence ,classical correlation and quantum discord. If we ajust the suitable Dx and J ,we will effectively control and increase the various quntum correlation.
