摘　　要：分别研究了温度对壬基酚聚氧乙烯醚（NP-10）／水体系和十二烷基聚氧乙烯醚（AEO12）／水体系形成的立方相液晶线性黏弹性的影响。5～23．5℃，NP-10／水体系形成的双连续立方相表现出明显的黏弹性特征，但其强度随温度的升高而降低，在15℃时有强度突变点；连续升温证明，由AEO12／水体系形成的不连续立方相在21．8-22．5℃存在玻璃态转化现象。The rheological properties of two different cubic lyotropic liquid crystal formed from nonylphenol ethoxylate- 10（ NP- 10） and dodecylphenol ethoxylate（ AEO12 ） in water were studied, especially the effect of temperature on the linear viscoelasticity of two different cubic phase was detected. For the V form cubic liquid crystal formed from NP - 10/H2O3, the bi-continuous liquid crystal keeps characteristic viscoelasticity between 5 - 23.5 ℃ ,but there is a decrement of strength with temperature and has a broken point in strength at 15 ℃. The I form cubic liquid crystal formed from AEO12/H2O exhibits a glassy transition between 21.8 - 22.5 ℃ during continuous temperature increase.
