摘　　要：通过偏光显微镜和在正常光照条件下视觉观察,测定了lecithin/AEO20/IPM/H2O体系在37℃时的拟三元相图。稳态流变实验表明,所有样品都表现出剪切稀释流体行为。在lecithin/AEO20/IPM/H2O体系中发现,ηγ=0.1值随着IPM含量的增加而减小,但随着水含量的增加而增大;σ0值随着IPM含量的增加逐渐减小,但随着水含量的增加变化较小。The pseudoternary phase diagram of lecihtin/AEO20/IPM/H2O system was determined by polarization microscopy and visual observation in normal light at 37℃. Steady rheological results indicate that all liquid crystal samples show shear- thinning behavior. In the lecihtin/AEO20/IPM/H20 system, with increase in IPM content, the values of ηγ = 0.1 and σ0 decrease. With increase in water content, the ηγ = 0.1 values increase, but the or0 values change little.
