摘要：

Shear-induced critical dynamics in a nonionic micellar solution has been investigated by measuring the viscosity-eta as a function of the shear rate S and a characteristic crossover temperature associated with S. The viscosity very close to T(c) varies as S--omega with omega=0.021 +/- 0.003 in excellent agreement with the expected value of omega=0.021. We also find a simple scaling relation between the temperature dependence and shear-rate dependence of eta. In addition, we confirm the feasibility of observing phase-separation dynamics near the critical point by shear quenching.
