摘　　要：利用液晶高分子共转Oldroyd流体B模型,研究了拉伸粘度的变化规律.作出了拉伸粘度随其它参数变化曲线.结论与实验结果一致.The relationship between the extensional viscosity and material parameters is studied through the analytical formulas of stress and extensional viscosity derived from the constitutive equation,boundary conditions and the equation of motion of co-rotational Oldroyd fluid B model.By using software MATLAB,the differential equations are solved and the curves of extensional viscosity with other parameters are drawn,and the influence of these parameters on the rheologic behavior is shown.These results qualitatively agree with the experimental results.

关 键 词：拉伸粘度 共转Oldroyd流体B模型 液晶高分子
