此图 所示为 lnZ 与 ln[sinh(ασ)] 线性拟合的结果，发现在两相区两者的相关系数为 0.984，而在单相区两者的相关系数高达 0.992，充分证明了真应变 0.8 下的本构模型具有较高的预测精度。

This figure shows the result of linear fitting between lnZ and ln[sinh(ασ)]. It is found that the correlation coefficient between the two in the two-phase region is 0.984, while the correlation coefficient between the two in the single-phase region is as high as 0.992, which fully proves the truth. The constitutive model under strain 0.8 has higher prediction accuracy.
