通过对太湖梅梁湾沉积物柱样中重金属汞总量的分析测量,并结合210Pb和137Cs计算沉积速率以确定年代,由此探讨了近百年以来Hg的富集特征和Hg的积累过程。结合磁化率与粒度特征,分析其与太湖沉积物中Hg含量的相关关系。结果表明,近百年来太湖沉积物中Hg含量呈持续增长的趋势,但是在20世纪80年代初期以来,沉积物中Hg的含量在逐渐降低,这与流域区域内重度污染工业规模的缩减是息息相关的;磁性矿物含量的
流畅的曲面外形成为现代产品设计的发展趋势。消失面作为一种独特的曲面形态,在产品造型设计中得到广泛应用;通过对典型消失面的结构和类型分析,阐述了基于Pro/E的消失面造型方法与规律;结合实例对4种典型消失面造型方法进行了应用,归纳了Pro/E下参数化的消失面处理技术;为消失面的人机工学应用提供一定的参考,丰富了CAD环境下的曲面造型手段,以提升设计师的造型能力和效率。
近日,第三届中望3D全球创新设计大赛正式结束,此次比赛吸引了来自中国、美国、波兰、阿根廷和德国等国家的优秀设计师,共提交了超过120个三维CAD设计作品。作品涉及"智能家居",也有将日常用品重新设计焕发新活力的创意作品。中望3D表示:此次大赛的参赛作品无论是完全创新的智能理念,还是进行微创新的传统设计,中望希望设计师能够利用中望3D设计软件创

A novel error-aware visual localization method is proposed that utilizes vertical planes,such as vertical building facades in urban areas as landmarks.Vertical planes,reconstructed from coplanar verti
针对复杂包裹相位图普遍存在相位跳变和解缠耗时的情况,设计了一种高精度快速的相位解缠算法。首先通过三步相移法得到包裹相位图,由包裹相位图计算产生质量图;再由相邻两像素点的质量值构造水平与竖直权值边,根据构造边权值的大小作为路径引导进行相位解缠,解缠过程以两像素点所构成边为单位,采用不连续解缠路径,逐次解缠所有像素点,有效降低了区域不连续、测量遮挡和环境噪声对解缠精度的影响,而且通过一次排序即可确定解
Spatial variation of dissolved organic carbon(DOC) in soils of riparian wetlands and responses to hydro-geomorphologic changes in the Sanjiang Plain were analyzed through in situ collecting soil sampl
Ecotones have received great attention due to its critical function in energy flux, species harbor, global carbon sequestration, and land-atmosphere interaction. This study investigated land use patte
Understanding the topographic context preceding the development of erosive landforms is of major relevance in geomorphic research,as topography is an important factor on both water and mass movement-r
