| 摘 要： | 以5个品牌酱牛肉为试样,从压缩试验及应力松弛试验研究中获得力学-流变学性质参数,利用SPSS软件进行非线性回归拟合,建立了广义Maxwell流变模型。结果表明:酱牛肉具有良好的压缩黏弹性力学性质,属黏弹性材料,五元件广义Maxwell模型适用于模拟酱牛肉的应力松弛现象。对应力松弛参数做主成分分析,应力松弛试验的7个参数可以分为两个主成分,归纳为2类,即黏弹特性和松弛时间。

| Abstract: | Five kinds of marinated cooled beef were compared on the compressed and stress relaxation properties to find out the parameters of mechanical and theological property.The SPSS software was used to make non-linear regression and created general Maxwell model.The results showed that marinated cooled beef has good viscoelastic mechanical property during compression,and it belongs to viscoelastic material,whose stress relaxation can be simulated by the general Maxwell model of five elements.By principal component analysis of stress relaxation,seven stress relax test parameters can be classified into two principal components,viscoelasticity and stress relaxation time. |

| Keywords: | spiced beef stress relaxation viscoelasticity stress relaxation time principal component analysis |
