This paper introduces computational fluid used in aerospace engineering, to deal with surface physical and mathematical foundations of CFD, this traffic problems such as queue/platoon distribution, dynamics （CFD）, a numerical traffic flow related problems. approach widely and successfully After a brief introduction of the paper develops CFD implementation methodology for modeling shockwave propagation, and prediction of system performance. Some theoretical and practical applications are discussed in this paper to illustrate the implementation methodology. It is found that CFD approach can facilitate a superior insight into the formation and propagation of congestion, thereby supporting more effective methods to alleviate congestion. In addition, CFD approach is found capable of assessing freeway system performance using less ITS detectors, and enhancing the coverage and reliability of a traffic detection system.

“革命老区+民族地区”叠加区域见证了中国各族人民选择中国共产党的历史,有着全国各族人民认同中国共产党的牢固根基。“革命老区+民族地区”叠加区域的特殊性在于它不仅是民族成分多元的革命老区,而且有别于一般少数民族聚居区。“革命老区+民族地区”叠加区域乡村地理位置偏远、经济发展水平落后、民族特质显著、发展依赖政策扶持。“革命老区+民族地区”叠加区域高质量推进乡村振兴,要充分考虑到区域因素与民族因素有机结合,进一步发掘丰厚的红色资源和革命元素。具体到实践,亟待在审视均衡性治理与国家化整合、政策衔接与战略规划的基础上,深入探析历史牵绊与现实挑战,把握政策联动、社会巨变、生态治理、文化集成的“后发”优势。“革命老区+民族地区”叠加区域乡村振兴行动的开展,需要加快产业融合振兴,积极培育“红色产业+民族特色产业”;就地盘活党史中的民族团结教育资源,为铸牢中华民族共同体意识凝心聚力;发挥红色文化与生态文化浸润功能,防止返贫文化惯性并防范民俗异化;有效推进基层全过程人民民主,扭转民主治理的“少-边-穷”困局。

伴随着我国工业化、城市化带来的经济繁荣和社会转型,基层社会的公共冲突问题也愈加凸显、社会稳定和底层秩序遭受冲击。近些年来,一些地方的基层社会不断探索出公共冲突治理的有效实现形式,充分化解了当地的矛盾和冲突,保障了社会的政治稳定和政治秩序。通过对地方实践的考察,不难发现,基层社会公共冲突治理的需要有效的实现形式,且有效实现形式的探索与一定的条件相关,不同的地方社会催生不同的治理方式。也正因如此,基层社会公共冲突治理有着特殊的路径,如特殊民情的养成、自治传统的发掘、社会组织的发展、现代技术的应用。
