中文摘要：

利用耗散粒子动力学模拟方法研究了顶盖驱动方腔流条件下，线性两嵌段共聚物胶束形态的变化．结果表明弱的流场对胶束的形态影响不大，但是在中等强度流场的作用下，小胶束会融合并形成条状胶束，而在很强的流场作用下，胶束会被破坏而形成体积更小的球状胶束．

英文摘要：

The morphology variations of the micelles under lid-driven flow were studied via dissipative particle dynamics simulations. The morphologies of the micelles under flow are different from that in equilibrium. The weak lid-driven flow has hardly changed the morphologies of micelles. We find the worm-like micelles under moderate lid-driven flow. In the strong lid-driven flow, smaller micelles are observed. The properties of the walls are also a dominant factor influencing the micelle morphologies.
