Chain-Die Forming ( CDF),a novel sheet metal forming technology,has been proposed and developed recently in Australia.The primitive objective of CDF was to overcome the theoretical and practical limitations in roll forming,including redundant deformation such as longitudinal stretching,axial bending,in-plane shearing and product defects such as end-flare,edge wave,curvature and twisting,et al.In automotive industry,Advanced High Strength Steels ( AHSS) have become one of the most popular materials and steel makers are developing different AHSS to fulfill the industrial requirements.However,the material s ductility is sacrificed despite its high strength and makes AHSS very difficult to form using conventional forming methods.CDF has been suggested to solve these problems and previous studies successfully showed the potentials of CDF in AHSS forming.In order to further study the CDF and commercialize the CDF to industries,an industrial pilot CDF is developed in order to perform full scale experiments and exhibit its capabilities to AHSS applications.Preliminary experiments were conducted with AHSS on the developed pilot and the results show that CDF is capable to make AHSS products with much higher quality than conventional forming techniques.

随着全球气候问题的日益严峻，低碳绿色的生活方式和消费模式将成为我国经济建设和社会生活的重要方向。城市规划作为引导城市发展的重要手段，必然成为快速城市化进程中控制碳排放的直接手段。发展理想的低碳城市，低碳城市规划理论与方法也就成为必然的关键技术。本文针对传统城市规划在这方面存在的不足，论述了打造低碳城市的一些方法。通过低碳城市规划寻求城市发展的低碳化方向，探索面向未来可持续发展的低碳城市发展模式。
我国大城市发展迅速，城市地域范围不断扩张，并向城市群体空间演进，出现了都市区等新的城市空间形态。但不断恶化的城市交通问题正成为制约都市区化积极推进的桎梏。传统的交通规划在城市规划中位于从属地位，通常都是先做城市规划，之后在进行交通规划，没有反馈的话语权，从而引发了一些列交通和社会问题。本论文从此角度出发做了一些创新性的工作，即在昆明远景城市空间发展不确定的条件下，自下而上的进行交通需求预测的研究，
城市垃圾处理关乎每一个市民的环境利益，是城市重要的环境民生问题与社会问题，不仅关系到居民的道德修养程度，也是一个城市生态文明程度的标志.本文基于生态城市理念，生命周期评价方法，提出在生态城市建设中，垃圾处理规划制定的原则和主要方法.以重庆市为例，提出将分类收集率提高到30％和无害化处理率达到100％，并根据垃圾组分属性优化垃圾末端处理模式等规划措施，由生命周期环境影响和经济成本评价表明，规划方案在

使用真空直流磁控溅射技术在DI材表面制备Al膜,并对镀铝DI材的可加工性与制备条件及铝膜的厚度之间的关系进行了研究.杯凸和冲杯试验表明铝膜沉积时的基板温度和膜厚对铝膜的附着力和可加工性有较大影响,当铝膜厚度大于2 μm时,铝膜的附着力变差.当基板温度从室温升至200℃时,铝膜的附着性和冲压性能有明显提升。
