对中国陕西省北部地区的榆林和靖边地区沙丘运动进行了评估。结果表明榆林和靖边地区总移动沙堆分别达24.433和21.147t。平均沙丘移动速率分别为4.61m和3.99m,而每月沙丘在榆林和靖边分别前进1.152m和0.997m。受影响最大的月份是6月份,接下来的是7—9月份。沙丘运动依赖于风速、沙丘高度、沙丘长度以及坡度。研究表明开垦地与沙丘方向相交时,受到极大影响,而与沙丘平行时,不受影响。
根据基于事例的设计方法 ,提出采用工序件的特征信息和夹具的结构特征信息来描述夹具的相似性 ,并建立了包括这 2方面主要特征信息为基础的事例索引码 ,设计了事例库的结构形式 ,创建了层次化的事例组织方式 ;同时 ,提出了基于知识引导的夹具事例检索算法 ,以及事例的修改和采用同族事例码进行相似事例的存贮 ,形成了基于事例推理的夹具设计 .所开发的原型系统在型号工程夹具设计等项目的设计过程中得到了应用
对流速仪法的测量要求、点位选择、测速垂线的布设及影响因素、如何消除测量中由于人为因素造成的系统误差、提高测量结果的准确度等问题进行了分析探讨

By using GIS and remote sensing techniques, the paper discusses how human activities have changed along the Yellow River in Henan province, China and how these altered activities have influenced the w
The desert and sandy land are the products of arid climate. The spatial distribution of modern deserts and sandy land in China and their relation to climate show following characteristics: arid and hy
