从方法论的角度评述作者等近年运用多尺度物理学解决复杂高分子体系加工与应用的一系列重要过程工程研究项目中的经验,包括复合材料高性能化,弱凝胶驱油,共混物加工分析,与含能浆体等。上述各种看来对象迥异的问题的解决,由于多尺度物理学的发展,可以用一种统一的思路来处理:在一个宽时空范围观察所包含的结构,而更重要的是其中的相互作用。然后研究各尺度的关联,抓住主要矛盾,尽量解开各尺度相互作用的耦合,建立适切物理模型,并在关键尺度上进行实验,达到理论与实验的统一。
From a methodological point of view, we review the experiences of authors in recent years using multiscale physics to solve a series of important process engineering projects in the processing and application of complex macromolecule systems, including high performance composite materials, weak gel flooding and blending processing Analysis, and energy-containing slurry and so on. The solutions to the various problems that seem to be quite different from one another are due to the development of multi-scale physics that can be dealt with in a unified way: to observe the contained structures in a wide range of time and space and, more importantly, to interact with them . Then, we study the correlation of each scale, grasp the main contradiction, try to uncouple the coupling of each scale, establish the appropriate physical model and carry out experiments on the key scales to achieve the unification of theory and experiment.
