中文摘要：

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／H20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leeithin／AE020／IP乩。H20体系中发现，ηγ=O．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。

英文摘要：

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.
