1杂草种子空间扩散模型的建立显示文摘 为通过模型分析和模拟来制定控制杂草的优化策略,我们设计并完成了一个杂草种子风扩散的室内实验。本文根据实验获得的数据建立了杂草种子扩散的空间模型。结果表明:杂草种子在任意方向上的扩散服从近似的高斯分布;在实验条件下,杂草种子扩散的空间分布型随风速的变化而变化。著名的Howard等〔5〕的杂草扩散模型是本文所建模型的特例。据此,我们推断Howard等〔5〕的模型所表示的分布型与一定高度的杂草种子在中等风速条件下扩散的分布型相似。王季槐 Svend Christensen Preben Klarskov Hansen 戚国正 2004贵州科学2004,,2:3
2Marine Structures: Future Trends and the Role of Universities显示文摘This paper emphasizes some of the challenges and trends associated with the future development of marine structures. Its main focus is on ways to improve the efficiency of energy-consuming ships, and on design challenges related to energy-producing offshore structures. This paper also discusses the analysis tools that are most needed to enable sustainable designs for future ships and offshore structures. The last section of the paper contains thoughts on the role of universities in education, research, and innovation regarding marine structures. It discusses curriculum requirements for maritime-technology education, basic research activities, and international cooperation.Preben Terndrup Pedersen 2015Engineering2015,1,1:3
3丹麦分布式能源发展之路显示文摘未来,可再生能源将成为全球能源供给的主要来源已是不可忽视的事实。随着化石能源的日益枯竭以及核能成本的持续上涨,可再生能源的介入为解决能源需求提供了更为灵活的选择。然而,可再生能源的发展也面临着巨大挑战,其发电出力的波动性势必需要一个全新的电力系统来适应。就风电和太阳能来说,一些技术成熟的有效集成解决方案在其波动性的适应上已卓有成效。在可再生能源集成解决方案的研究上,丹麦一直走在世界前沿,尤其是热电联产方式的区域集中供热供冷系统的运营更是非常成功,其模式也值得推广。Preben Maegaard 张玥 2015风能2015,,1:2
