矿泉水瓶再生设计研究

由于500ml左右矿泉水瓶瓶口具有统一的螺纹规格,其次,瓶体的容量也具有接近统一的标准,这就为矿泉水瓶再生设计的开发提供了必要的前提。市场上关于矿泉水瓶的再生设计多利用矿泉水瓶作为盛水的容器,而没有继续探讨其盛放小型垃圾(瓜子壳,纸屑,铅笔屑等)的功能。本文以绿色设计中延长产品生命周期的理念为原则,以联想法、模仿法及组合法等产品设计方法为指导,推出一款全新的使用矿泉水瓶衍生功能的产品,并着重介绍在本设计进行的过程中得出的新的设计方法:系统化条件下的功能衍生法。通过这款设计来说明现有产品衍生出新的功能的可行性,并总结一定的设计经验与设计方法,为以后进行相关设计奠定理论和方法基础。     

湘桂铁路下穿全兴高速公路设计方案优化

新建湘桂铁路于DK233+503处下穿全兴高速公路,原设计采用顶进框架桥方案。通过对安全质量的可控性、经济、工期等方面进行综合比选,取消顶进框架桥,变更为公路箱梁桥上跨铁路方案,采用分幅封道、分幅施工,既安全快速地穿过全兴高速公路,又创造了良好的经济效益和社会效益,为类似的工程提供了一定的参考价值。

The living commons of West Tyrol,Austria: Lessons for land policy and land administration

A right of commoners to pastures existed since the Early Middle Ages in Anglo-Saxon England and the European mainland, including Tyrol in Austria. Lowland commons institutions were largely dissolved by the 19th century; however, in the European Alps contiguous commons remain alive. Some two thousand alpine commons institutions are registered in the Tyrolean parcel cadaster and land registry. A specific study of West-Tyrolean commons (known as Agrargemeinschaft or AGMs), framed by Ostrom's design principles is presented. General lessons for land policy and land administration are extracted. An interview period was split between the Inn valley and the Ötztal. Roughly half are considered independent: others are regulated by the Tyrolean Agricultural Authority. Some AGMs hold the full bundle of land rights: others only hold pastoral and forestry rights. AGMs consisted either of a single cadastral parcel or several contiguous parcels. In the Inn valley villages the pastoral commons were owned by the municipalities, while in the researched Ötztal, AGMs are frequently the full owners of the commons. AGM membership ranges between 5 and 60 farm households. The number of livestock units pastured was in most cases stipulated in approved regulations. Alpine commons larger than 200 ha are also hunting-zones: revenue is collected from the lease of hunting rights. Most of the alpine commons are designated and used as ski-zones. Upper portions of two alpine commons in the Ötztal are state protected natural areas. The number of farms with pastoral rights is declining at District and State level. Key lessons for land policy and land administration include: Ostrom's design principles being a precondition rather than a panacea; commons institutions requiring one clear ownership party; both public and collective ownership producing success; publically owned commons requiring a local representative; small membership numbers being preferable; small shareholdings not being preferable; decentralized governance being beneficial; internal democratic elections being beneficial; internal boundary records being superfluous; explicit sanctions being superfluous; mixed economies being acceptable; and geography being a significant influence on the longevity of pastoral commons.
