英文摘要: This project aims at the key problems of design optimization and multi-scale modeling of metallic fibrous porous carriers, which are with complex micro-topographical features. It presents the novel approach of fine feature modeling that is process-controllable. It integrates multi-disciplines to investigate new approach of digitized modeling so as to achieve a fine description and effective control on the multi-scale topological features of the carriers' structure. By introducing different fractal theories, the study will utilize advanced experimental techniques and measures to explore the approach of digitized description, which will be able to effectively represent the fibrous porous topography and internal topological structure of carriers; By research into the composite modeling approach of two different fractal representations, a multi-scale fine feature model that is unified at both macro- and micro- scales can be constructed. By research and analysis on the related forming mechanism and process patterns, the mapping relationship between the topographical features of fine feature models and correlated sets of process parameters will be investigated, and hence the constraints of topographical features and controlling mechanism on process parameters can then be established. Combining with the extreme demand
