| 1 | Fraction distribution and risk assessment of heavy metals in sediments of Moshui Lake显示文摘在城市的湖检验重金属污染的地位和风险在中国,几重金属的分发(例如, Cr, Cu, Ni, Pb, Zn ) 在莫休·莱克,的沉积 Hangyang 区域,武汉城市,被描绘。快速的都市化的过程和这个区域的工业化也被学习在沉积与金属累积侧面发现它的关系。在沉积的重金属的全部的集中比严重效果水平(SEL ) 高,这被发现,根本采样地点,除了那些在河边的地区。Cr 和 Cu 最大值集中是 1, 780 和 1, 250 mg/kg,约 16 并且 11 倍于 SEL,价值,和他们在一件样品象 32 厘米一样显得深。碳酸盐和 Zn 的可交换的部分是超过 50% 全部的 Zn 内容,导致根据风险评价代码的很高的风险(皇家装甲兵) 。为 Cu 和 Ni,媒介皇家装甲兵,价值被作出对有利的裁决碳酸盐和可交换的部分 11%20% 。作为在水的系统的沾染物的敏感指示物,在沉积的重金属反映地区性的都市化,工业化,和环境管理的结果。与快速的都市化,沉积 Pb 和 Zn 集中增加了。试验性的结果证明高沉积的重金属集中源于快速的都市化和工业化,它将绝对在城市的湖导致实质的水的环境衰落。 | LIU Honglei LI Liqing YIN Chengqing SHAN Baoqing | 2008 | Journal of Environmental Sciences2008，20，4： | 46 |
| 2 | Numerical Analysis of Structural Progressive Collapse to Blast Loads显示文摘After the progressive collapse of Ronan Point apartment in UK in 1968, intensive research effort had been spent on developing guidelines for design of new or strengthening the existing structures to prevent progressive collapse. However, only very few building design codes provide some rather general guidance, no detailed design requirement is given. Progressive collapse of the Alfred P. Murrah Federal building in Oklahoma City and the World Trade Centre (WTC) sparked again tremendous research interest on progressive collapse of structures. Recently, US Department of Defence (DoD) and US General Service Administration (GSA) issued guidelines for structure progressive collapse analysis. These two guidelines are most commonly used, but their accuracy is not known. This paper presents numerical analysis of progressive collapse of an example frame structure to blast loads. The DoD and GSA procedures are also used to analyse the same example structure. Numerical results are compared and discussed. The accuracy and the applicability of the two design guidelines are evaluated. | HAO Hong WU Chengqing LI Zhongxian ABDULLAH A K | 2006 | Transactions of Tianjin University2006，12，B09： | 6 |
| 3 | Experimental and Numerical Investigation of the Unsteady Tip Leakage Flow in Axial Compressor Cascade显示文摘For convenience of both measurement and adjusting the clearance size and incidence, the current research is mainly conducted by experiments on an axial compressor linear cascade. The characteristics and the condition under which the unsteadiness of tip leakage flow would occur were investigated by dynamic measuring in different clearances, inlet velocities and incidences. From the experiment it is found that increasing tip clearance size or reducing rotor tip incidence can affect the strength of the tip clearance flow. Then the experimental results also indicate the tip leakage shows instability in certain conditions, and the frequency of unsteadiness is great influenced by inflow angle. The condition of occurrence of tip leakage flow unsteadiness is when the leakage flow is strong enough to reach the pressure side of the adjacent blade. The main cause of tip leakage flow unsteadiness is the tip blade loading. | Chengqing Li Tingfeng Ke Jingxuan Zhang Hongwu Zhang Weiguang Huang | 2013 | Journal of Thermal Science2013，22，2： | 3 |
| 4 | Statistical downscaling model for late-winter rainfall over Southwest China显示文摘A statistical downscaling model is built for the late-winter rainfall over Southwest China(SWC).A partial-correlation method is used for selecting factors.The results show that the selected factors for late-winter rainfall in SWC are sea level pressure in Western Europe(SNAO)and sea surface temperature in Western Pacific(WPT).SNAO is related to the southern pole of North Atlantic Oscillation(NAO)and excites Southern Eurasian teleconnection,which influences the development of the southern branch trough and the water vapor transport to SWC.WPT indicates the variability of ENSO in the tropical Western Pacific.WPT excites Pacific-East Asia teleconnection and an anticyclone(cyclone)is formed in the southern part of China and suppresses(enhances)rainfall over SWC.A regression statistical downscaling model using SNAO and WPT shows good performance in fitting the variability of late-winter rainfall in the whole SWC region and every observation station,and the model also shows strong robustness in the independent validation.The statistical model can be used for downscaling output from seasonal forecast numerical models and improve the SWC late winter rainfall prediction in the future. | RUAN ChengQing LI JianPing FENG Juan | 2015 | Science China Earth Sciences2015，58，10： | 2 |
| 5 | Application of Bionic Tribology in Water-Lubricated Bearing:A Review显示文摘Water-lubricated bearing has become the development trend in the future because of its economy and environmental friendliness.The poor friction performance under low speed and heavy load seriously limits the popularization and application of water-lubricated bearings.Learning from nature,the phenomenon of low friction and wear in nature has aroused great interest of scientists,and a lot of research has been carried out from mechanism analysis to bionic application.In this review,our purpose is to provide guiding methods and analysis basis for the bionic design and theoretical research of anti-friction and anti-wear of water-lubricated bearings.The development of water-lubricated bearing materials are described.Some typical examples of natural friction reduction and drag reduction are introduced in detail,and several representative preparation methods are listed.Finally,the application status of bionic tribology in water-lubricated bearings is summarized,and the future development direction of water-lubricated bearings is prospected. | Xuefei Li Zhiwei Guo Qiren Huang Chengqing Yuan | 2022 | Journal of Bionic Engineering2022，19，4： | 2 |
