摘要：
The dynamics of phase separation for a binary fluid subjected to a uniform shear are solved exactly for a model in which the order parameter is generalized to an n-component vector and the large-n limit is taken. Characteristic length scales in directions parallel and perpendicular to the flow increase as (t(5)/lnt)(1/4) and (t/lnt)(1/4) respectively. The structure factor in the shear-flow plane exhibits two parallel ridges as observed in experiment.
