中文摘要：

在（95±5）℃的条件下,采用不同比例的硬脂酸钾（PS）、硬脂酸钠（SS）、液体石蜡（PL）和聚乙烯醇（PVA）共混搅拌制备出可作为肝脏损伤能量评估模型的塑性材料.采用Instron 8871动态疲劳材料拉伸压缩试验机测定不同比例的塑性材料的力学性能,结果表明,PS/SS/PL/PVA质量比为35/35/28/2时,变形抗力为0.056MPa,极限压缩应变为10.673％,塑性材料具有良好的塑性变形性能;扫描电子显微镜（SEM）观察结果与力学性能测试结果吻合.

英文摘要：

The plastic material for a liver injury stress assessment model was prepared using a blend of potas- sium stearate （PS）, sodium stearate （SS）, polyvinyl alcohol （PVA） and paraffin liquid （PL） at different weight ratios under （95±5） ℃. The mechanical properties of different ratios of plastic material were investigated via a compression test using Instron 8871. The PS/SS/PL/PVA blend with a weight ratio of 35/35/28/2 had superior plastic deforma- tion properties, with deformation resistance and compressive strain of 0. 056 MPa and 10. 673%. The result of SEM study agrees with that of the mechanical property test.
