用激光散射法研究了两种低共溶点的非离子两亲物溶液的临界行为。H2 O-C8 Et 4体系的临界指数γ和ν分别为γ= 1.15和ν= 0.57; H2 O-C12 Et 8体系的临界指数γ和ν分别为γ= 0.90和ν= 0.44。这两组值都不同于以前发现的系统H 2 O-C 12 Et 6。描述所观察到的非普遍性的临界胶束溶液可能需要三维模型，表现出连续变化的临界指数。
The critical behavior of two nonionic-amphiphile solutions showing a lower consolution point is investigated by laser-light scattering. The critical exponents γ and ν take the values γ= 1.15 and ν= 0.57 for the system H 2 O-C 8 Et 4, and γ= 0.90 and ν= 0.44 for H 2 O-C 12 Et 8. Both sets of values are different from those previously found with the system H 2 O-C 12 Et 6. The description of the observed nonuniversality of critical micellar solutions may require three-dimensional models which exhibit continuously varying critical exponents.
