| 摘 要： | 软物质是指处于固体和理想流体之间的复杂态物质，主要包括聚合物、表面活性剂、液晶、胶体悬浮液、以及生物大分子等。软物质能够对外界微小的作用产生强烈的非线性响应，并展现出丰富的有序自组装相态。作为一种新颖的模拟技术，耗散粒子动力学方法非常适合在介观尺度上对软物质体系的复杂行为进行合理的描述。本文对耗散粒子动力学模拟方法的发展及一些应用进行了系统评述。耗散粒子动力学模拟方法体现了分子动力学与格子Boltzmann模型的优点，通过与其它理论模型（如Flory-Huggins理论、Smoothed particle hydrodynamics模型等）相结合，该方法能够在介观尺度上有效地研究聚合物熔体和溶液体系、生物膜及囊泡体系以及胶体悬浮液等体系的行为。这些研究结果，对新材料的研发、特殊材料的制备、以及材料加工条件的选择具有十分重要的科学意义和实际应用价值。 |

| Abstract: | In this paper we start from the stratification of physical world to discuss the situation of condensed matter physics within the context of physics today, and we show why this branch of physics is still full of vitality due to the dialectical relationship between complexity and simplicity. Further we try to define the scope of condensed matter physics, stressing the importance of various types of condensation phenomena both in configuration space and momentum space. we also try to make the boundaries of region of validity for the methods of quantum physics and classical physics in its theoretical treatments. Finally we trace the historical development of this discipline, analyze the evolution of its conceptual framework, and try to decipher the paradigms corresponding to solid state physics and condensed matter physics respectively in order to help those who are now engaged in the study of condensed matter physics. |
