The simulation results for binary blends under shear boundary condition reveal that at a given shear velocity there exists the competition between shear and component repulsion. In low viscosity and strong repulsion system, it is the repulsion effect that mainly determines the morphologies at equilibrium state; in the system with low viscosity and weak repulsion, the dominant factor is the shear. However, in system with low viscosity and weak repulsion, we observed a characteristic time. Before that time the repulsion effect dominates the phase separation, thereafter it is the shear that dominates the phase separation.
剪切边界条件下二元共混体系研究结果表明在确定的剪切速率下存在剪切作用和排斥作用的竞争：在低粘度强排斥体系中平衡态的相形态主要决定于排斥作用；在低粘度弱排斥体系中主导因素是剪切作用；在高粘度强排斥体系中观察到一个特征时刻，在特征时刻之前排斥作用占优势，之后剪切作用占优势。
