| 1 | New development thoughts on the bio-inspired intelligence based control for unmanned combat aerial vehicle显示文摘Bio-inspired intelligence is in the spotlight in the field of international artificial intelligence,and unmanned combat aerial vehicle(UCAV),owing to its potential to perform dangerous,repetitive tasks in remote and hazardous,is very promising for the technological leadership of the nation and essential for improving the security of society.On the basis of introduction of bioinspired intelligence and UCAV,a series of new development thoughts on UCAV control are proposed,including artificial brain based high-level autonomous control for UCAV,swarm intelligence based cooperative control for multiple UCAVs,hy-brid swarm intelligence and Bayesian network based situation assessment under complicated combating environments, bio-inspired hardware based high-level autonomous control for UCAV,and meta-heuristic intelligence based heterogeneous cooperative control for multiple UCAVs and unmanned combat ground vehicles(UCGVs).The exact realization of the proposed new development thoughts can enhance the effectiveness of combat,while provide a series of novel breakthroughs for the intelligence,integration and advancement of future UCAV systems. | DUAN HaiBin 1 ,SHAO Shan 2 ,SU BingWei 3 &ZHANG Lei 41 State Key Laboratory of Science and Technology on Holistic Flight Control,School of Automation Science and Electrical Engineering, Beijing University of Aeronautics and Astronautics,Beijing 100191,China 2 Flight Control Department,Shenyang Aircraft Design and Research Institute,Shenyang 110035,China 3 Beijing Institute of Near Space Vehicle’s System Engineering,Beijing 100076,China 4Integration and Project Section,Air Force Equipment Academy,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，8： | 32 |
| 2 | 细沟侵蚀动态过程模拟数学模型和有限元计算方法显示文摘建立了集中水流作用下均质土壤坡面上细沟侵蚀动态模拟数学模型。模型包括根据质量守恒原理推导而得到的变沟宽水流连续性方程和泥沙运移方程;根据动量守恒方程推得到的水流动力学方程;由紊流冲击分布概率来确定的土壤剥离方程;过量泥沙采用沉积的一阶沉积方程。模型还考虑了沟床形态、水流动力、土壤侵蚀与泥沙沉积形成相互依赖的反馈环,具有表达细沟的空间变化和时间演变的能力。给出了利用有限元方法对水动力学方程及泥沙运移连续方程进行顺序求解的数值计算公式以及模型数值求解的具体步骤。 | 雷廷武 姚春梅 张晴雯 Mark Nearing 邵明安 梅树立 | 2004 | 农业工程学报2004，20，4： | 13 |
| 3 | 细沟侵蚀动态过程模拟室内试验和模型验证研究显示文摘进行了一系列室内试验,以验证模拟细沟演变动态过程的数学模型。该模型模拟了细沟水流的动态过程、水力学特性参数的空间变化、细沟中土壤的剥离、运输及沉积过程;模拟了细沟在侵蚀过程中的形态演变,其中包括沟宽、沟深、局部坡度在空间上的差异及其随时间的变化;模拟了细沟侵蚀/泥沙沉积后局部细沟形态的变化对细沟水流反馈效应。试验土壤为砂壤土,采用的坡度为:3%,5%,7%;3个流量:7.6,11.4,15.2L/min。在同一试验条件不同工况下对模型进行了验证,同时对细沟中沿程水流速度和细沟末端的侵蚀产沙量进行了模拟值和试验实测值的对比。结果表明,模型预测值和实测细沟形态演变值具有很好的一致性,模型中提出的侵蚀、沟床形态变化和水力学特性参数间的互反馈环效应可以反映细沟侵蚀的动态演变过程和发展趋势。 | 姚春梅 雷廷武 张晴雯 Mark Nearing 邵明安 | 2004 | 农业工程学报2004，20，5： | 4 |
| 4 | A review of concentrated flow erosion processes on rangelands:Fundamental understanding and knowledge gaps显示文摘Concentrated flow erosion processes are distinguished from splash and sheetflow processes in their enhanced ability to mobilize and transport large amounts of soil,water and dissolved elements.On rangelands,soil,nutrients and water are scarce and only narrow margins of resource losses are tolerable before crossing the sustainability threshold.In these ecosystems,concentrated flow processes are perceived as indicators of degradation and often warrant the implementation of mitigation strategies.Nevertheless,this negative perception of concentrated flow processes may conflict with the need to improve understanding of the role of these transport vessels in redistributing water,soil and nutrients along the rangeland hillslope.Vegetation influences the development and erosion of concentrated flowpaths and has been the primary factor used to control and mitigate erosion on rangelands.At the ecohydrologic level,vegetation and concentrated flow pathways are engaged in a feedback relationship,the understanding of which might help improve rangeland management and restoration strategies.In this paper,we review published literature on experimental and conceptual research pertaining to concentrated flow processes on rangelands to:(1)present the fundamental science underpinning concentrated flow erosion modeling in these landscapes,(2)discuss the influence of vegetation on these erosion processes,(3)evaluate the contribution of concentrated flow erosion to overall sediment budget and(4)identify knowledge gaps. | Sayjro K.Nouwakpo Christopher J.Williams Osama Z.Al-Hamdan Mark A.Weltz Fred Pierson Mark Nearing | 2016 | International Soil and Water Conservation Research2016，4，2： | 2 |
| 5 | The Cosmic Dust in Suzhou Granite:Ablated Products of a Cometary Explosion | Hu Zhong-wei,Wang Er-kang,Wan Yu-qiuDepartement of Astronomy,Nanjing University,Nanjing 210093,China Department of Earth Sdence,Nanjing University,Nanjing 210093,China Cosmic dust has been collected in large number from deap-sea sediments,Greenland ice deposits,the stratosphere and space,of cosmic dust,some are the unmelted micrometeorite,and most are the ablated products of me-teoroids in the atmosphere.Cosmic dusts were recovered from two sites of the 1908 Tunguska explosion and the 1965 Revelstoks explosion Since 1987,a large number of microspherules have been extracted from Suzhou granite of China Their suface and section structures,mineral and chemical composition show that these microspherules are of the ablated cosmic dust.The microspherules occurred in the inner contact complex intrusion.It suggests that the microspherules may be products of the same event and were aggergated in some strata and then captured by the emplacement of granitic magma.Although the microspherules are similare to other ablated cosmic dusts,there are some diferences.Our calculated results of cometary motion through the atmosphere and explosion show that the microspherules may be the ablated dust of a comet with mass above 1015g at its explosion near the ground. | 1996 | 紫金山天文台台刊1996，15，3： | 2 |
