金属加工过程中应力状态的分析方法

分析简单地拉伸、压缩和扭转的情况时,应力状态能容易地被确定.但是,实际上在金属加工过程中材料是承受复杂的应力状态,在模具——工件接触面上增加有摩擦力.而且,这些应力和摩擦力一般地沿着接触面变化.准确的计算或预测载荷、力、应力和温度,不但对设计适宜的设备是重要的,而且对研究工艺期间材料的变化过程也是重要的.本文将讨论材料变形过程中所运用的主要分析方法及其优缺点.     

Industrial Cluster Upgradation of Regenerated Resources in Miluo City

With China's rapid economic growth, ecological construction and environmental protection become increasingly important. The regenerated resources industry is an effective way to solve problems, such as resources depletion, energy shortage, and pollution, and it also has strategic importance for the construction of a resource-conserving and environment-friendly society. The regenerated resources industry has been established in Miluo for long time, which includes a recycling system, a processing and utilization system, and a refuse decontamination system. An industrial cluster is in its early stage of development. In order to solve current problems, such as short industrial chain, low processing rate, and low added value, the industrial cluster should be dynamically upgraded by means of technology innovation, chain nucleus creation, and chain extension. We think the industrial cluster of regenerated resources will become a local brand for Miluo, from which other regions or cities will gain valuable experiences and inspirations.

对低影响开发与海绵城市的再认识

海绵城市建设是在继承我国古代先贤智慧和参考国外经验,系统总结我国雨洪管理领域长期研究和实践经验的基础上,结合我国城市水系统实际问题提出的城市发展方式,其核心是构建基于绿灰结合的现代城市雨洪控制系统,通过"渗、滞、蓄、净、用、排"综合措施,实现"治涝"与"治黑"等多重目标。低影响开发是海绵城市建设的重要指导思想,也是海绵城市核心技术体系的重要组成部分。正确认识低影响开发与海绵城市的内涵与联系,对于进一步在全国范围内落实低影响开发建设模式,科学推进海绵城市建设具有重要意义。
