方向关系在地理信息系统(GIS)中占据着十分重要的地位,由于它的模糊性和依赖空间实体形状的特性,使得它的形式化描述和判断比较困难。本文在三角形模型(CDR)方法的基础上,利用最小矩形(MBR)四边的Voronoi多边形及其边界,形式化描述了方向关系,进而将方向关系分为主方向关系和次方向关系,并分别给出了两者利用MBR四边Voronoi多边形及其边界判断的算法。

Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.

淡水资源是人类生存与经济社会发展的物质基础。我国西北地区的经济开发与发展,水资源问题特别突出。文章就西北地区开发中贯彻“人与自然和谐共存的方针”问题作了进一步讨论,提出在开发利用西北水资源过程中,必须从西北地区水资源总量不大,年蒸发量特别大,年降水量又很小的情况出发,积极节流开源,节约用水,防止水资源浪费,提高用水效益,减少水的污染,回收水资源,改善环境。建议积极走“藏水于地下”,扩大地下水与合理开发地下水之路。同时坚持不断地扩大可用的淡水资源。
