纤溶酶治疗下肢溶静脉血栓在临床症状、体征明显改善或消失的同时，血液流变学的指标也明显好转，无严重并发症，具有较好的临床疗效，值得进一步观察研究和应用。

According to the double-axis experiment and the uniaxial tension experiment, shear relaxation modulus and bulk relaxation modulus are obtained. Fractional exponent models[23][24][25] are applied to shear relaxation modulus and bulk relaxation modulus. The theory is proved by constant amplitude cyclic strain experiment. Better results are obtained from the comparison of theory curves and experiment results.

通过双轴拉压实验来确定材料的切变松弛模量，单轴拉伸实验来确定材料的体变松弛模量，对这两种模量均采用分数阶指数的形式来进行拟合，再用等应变幅循环历史的实验验证了理论，得到了较好的结果。
