图7 加入 $T_{f}$ 后的新模型在不同浓度溶液中的拟合情况， $T_{f}$ 用经验公式和参数拟合两种方法获取。其中实线未考虑 $T_{f}$ 影响，短划线 $T_{f}$ 通过经验公式计算，虚线的 $T_{f}$ 通过拟合获得

Fig.7 Unfrozen water content changing with temperature while considering effects of $T_{f}$ under different solute concentrations （Note： solid line is not considered the influence of $? T_{f}$ ，short line $? T_{f}$ is calculated by the empirical formula and the dashed line $? T_{f}$ is obtained by fitting）
