1TRANSPORT OF THE SUSPENDED SEDIMENT IN THE CHANGJIANG ESTUARY显示文摘The Changjiang River is characterized by the enormous volume of runoff and the great amount of sediment load with remarkable seasonal variation. The annual runoff sometimes is respondent to the amount of sediment load, and sometimes not. The amount of monthly sediment load after the month of the maximum runoff is larger than those before the month. The sediment concentration and net quantity of sediment transport in the vicinity of the river mouth varies greatly in time between the ebb and flood, spring and neap, and dry seasons and flood seasons. The three bifurcations also have differences in concentration and net quantity in space. Even in the same bifurcation they have differences in and out of the sand bar. At present, the North Channel is the main passage for water and sediment load emptying into the sea from the Changjiang River. More than 50 percent of the sediments from the river basin are deposited nearby the South Branch entrance and the main depositional area is situated in subaqueous delta off the South Channel. Between 122°30’E and 123°E is an important boundary for eastward sediment dispersion from which the suspended sediment are dispersed towards the east by south.SHEN Huanting Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China LI Jiufa Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHU Huifang Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China HAN Mingbao Institute of Esturaine and Coastal Research, East China Normal University, Shanghai, China ZHOU Fugen Department of Marine Geology, Tongji Univcrsity, Shanghai, China 1992International Journal of Sediment Research1992,7,3:37
2施氮量和灌溉方式的交互作用对东北粳稻稻米品质的影响显示文摘[目的]探讨不同灌溉方式和氮肥对水稻品质的影响及其互作效应。[方法]以常规粳稻沈稻47和杂交粳稻粳优 586 为材料,进行防雨棚盆栽试验,设置浅水层灌溉、浅湿灌溉、轻干湿交替灌溉和重干湿交替灌溉4种灌溉方式及正常施氮(normal nitrogen, NN, 180 kg/hm^2)和高氮(high nitrogen, HN, 220 kg/hm^2)2种氮肥水平,研究不同肥水处理对稻米品质的影响。[结果]灌溉方式和施氮量对稻米品质有明显的互作效应,在正常施氮和高氮水平下,稻米的加工品质、外观品质、营养品质和蒸煮食味品质均以轻干湿交替灌溉为佳。正常施氮水平下,重干湿交替灌溉下稻米的整精米率、胶稠度、最高黏度和崩解值低于浅水层灌溉,而其垩白度、垩白粒率、直链淀粉含量及消减值却高于浅水层灌溉。高氮水平下,重干湿交替灌溉处理的加工品质、外观品质、营养品质和蒸煮食味品质优于浅水层灌溉,但二者间差异不显著。灌溉方式对氨基酸的影响因施氮量和品种的不同而存在差异。常规施氮水平下,轻干湿交替灌溉显著提高了稻米的总氨基酸含量;高氮水平下,重干湿交替灌溉显著提高了沈稻47的氨基酸总量,而粳优586总氨基酸含量则在轻干湿交替灌溉处理下取得较高值,必需氨基酸和非必需氨基酸含量与总氨基酸含量趋势一致。[结论]轻干湿交替灌溉方式可以改善稻米品质。在本研究条件下,沈稻 47和粳优586分别以轻干湿交替灌溉和施氮量为180 kg/hm^2和施氮量为220 kg/hm^2时,米质较好。周婵婵 黄元财 贾宝艳 王岩 李瑞峰 王术 冯跃 Fugen Dou 2019中国水稻科学2019,33,4:18
3Soil Enzyme Activities and Organic Matter Composition Affected by 26 Years of Continuous Cropping显示文摘The study was to determine the long-term effects of subtropical monoculture and rotational cropping systems and fertilization on soil enzyme activities and soil C, N, and P levels. Cropping systems included continuous sorghum(Sorghum bicolor L.), cotton(Gossypium hirsutum L.), corn(Zea mays L.), and cotton/sorghum rotations after 26 years of treatment imposition. Soil under continuous sorghum and continuous corn had 15% and 11%, respectively, greater C concentrations than soil under continuous cotton.Organic C was 10% higher at 0–7.5 cm than at 7.5–15 cm. Total N followed similar trends with soil depth as organic C. Continuous sorghum had 19% higher total N than other crop species and rotations. With fertilization, continuous cotton had the highest total P at 0–7.5 cm and sorghum had the highest at 7.5–15 cm. Soil total P was 14% higher at 0–7.5 than at 7.5–15 cm, and fertilization increased 15% total P compared to unfertilized soil. Arylsulfatase, alkaline phosphatase, and β-d-glucosidase activity were the highest for sorghum and the lowest for cotton. Rotation increased enzyme activities compared to continuous cotton but not for continuous sorghum. Of all crop species and rotations, continuous cotton generally showed the lowest levels of organic matter and enzyme activities after 26 years. Fertilization significantly increased the yields for all cropping systems, but rotation had no significant effect on either sorghum or cotton lint yield compared to each crop grown in monoculture. Long-term cropping did not increase soil organic matter levels beyond short-term gains, indicating the difficulty in promoting C sequestration in subtropical soils.Fugen DOU Alan L.WRIGHT Rao S.MYLAVARAPU JIANG Xianjun John E.MATOCHA 2016Pedosphere2016,26,5:12
4Co-incorporation of rice straw and leguminous green manure can increase soil available nitrogen(N)and reduce carbon and N losses:An incubation study显示文摘Returning rice straw and leguminous green manure alone or in combination to soil is effective in improving soil fertility in South China.Despite the popularity of this practice,our understanding o f the underlying processes for straw and manure combined application is relatively poor.In this study,rice straw(carbon(C)/nitrogen(N)ratio of 63),green manure(hairy vetch,C/N ratio of 14),and their mixtures(C/N ratio of 25 and 35)were added into a paddy soil,and their effects on soil N availability and C or N loss under waterlogged conditions were evaluated in a 100-d incubation experiment.All plant residue treatments significantly enhanced C〇2 and CH4 emissions,but decreased N2O emission.Dissolved organic C(DOC)and N(DON)and microbial biomass C in soil and water-soluble organic C and N and mineral N in the upper aqueous layer above soil were also enhanced by all the plant residue treatments except the rice straw treatment,and soil microbial biomass N and mineral N were lower in the rice straw treatment than in the other treatments.Changes in plant residue C/N ratio,DOC/DON ratio,and cellulose content significantly affected greenhouse gas emissions and active C and N concentrations in soil.Additionally,the treatment with green manure alone yielded the largest C and N losses,and incorporation of the plant residue mixture with a C/N ratio of 35 caused the largest net global warming potential(nGWP)among the amended treatments.In conclusion,the co-incorporation of rice straw and green manure can alleviate the limitation resulting from only applying rice straw(N immobilization)or the sole application of leguminous green manure(high C and N losses),and the residue mixture with a C/N ratio of 25 is a better option because of lower nGWP.Guopeng ZHOU Weidong CAO Jinshun BAI Changxu XU Naohua ZENG Songjuan GAO Robert M.REES Fugen DOU 2020Pedosphere2020,30,5:10
5Nano-bio interfaces probed by advanced optical spectroscopy:From model system studies to optical biosensors显示文摘Research in biology and medicine is a rapidly expanding field incorporating some of the most fundamental questions concerning structure, function, and purpose. The forefront of new research demands access to advanced techniques and instrumentation capable of probing these unanswered questions. Over the past several decades, nano-scale materials and devices ranging from quasione dimensional quantum dots to two dimensional graphene sheets have been engineered and have found applications in nano-bio imaging and spectroscopy. In this review, the incorporation of nanomaterials into three influential spectroscopic and microscopic techniques including fluorescence microscopy, surface plasmon resonance, and sum frequency generation will be introduced. Fluorescence imaging has visualized nanomaterials as compliments or replacements to comparable organic fluorphores, act as a quencher for FRET-based sensing, and serve as a nanoscaffold for molecular beacons. Their versatility in coating materials makes nanomaterials an excellent targeting molecule for any cellular macromolecule or structure. In addition to the targeting capabilities of nanomaterials in fluorescence imaging, surface plasmon resonance has incorporated nanomaterials for applications in signal enhancement, selectivity of target molecules, and the development of more refined and accurate detection. Functionalized nano-particles enhance the capabilities of sum frequency generation vibrational spectroscopy by providing unique surface chemistry which alters target molecule interactions and orientations. In summary, the incorporation of nanomaterials has greatly enhanced the field of biology and medicine and has allowed for the continual advancement of not only research but instrument development.ZHANG XiaoXian HAN XiaoFeng WU FuGen JASENSKY Joshua CHEN Zhan 2013Chinese Science Bulletin2013,58,21:9
6Construction schedule risk analysis of high roller-compacted concrete dams based on improved CSRAM显示文摘The applied technology of high roller-compacted concrete(RCC) dams is quite complicated because of various risk factors, including the weather condition, supply of concrete aggregate, efficiency of transport machinery and dam surface machinery, and so on. In order to ensure the comprehensiveness, accuracy and objectivity of construction schedule risk analysis, a mathematical model called improved correlated schedule risk analysis model(CSRAM) is proposed in this paper. This model takes into account not only the construction features of high RCC dams, but also the stochastic variations of risk factors with the construction schedule, as well as their comprehensive effects. Using Monte Carlo method to solve this model enables the completion probability of a high RCC dam construction within plan time, and uncertainty analysis of risk factors. Compared with the conventional CSRAM, the improved CSRAM has higher completion probability and more convergent distribution of a simulation period, making analysis results more accurate and closer to actual engineering conditions. Among the ten risk factors selected, efficiency of dam surface machinery and proficiency of workers are found to be of the maximum uncertainty.ZHONG DengHua YANG ShiRui CHANG HaoTian YU Jia YAN FuGen 2015Science China(Technological Sciences)2015,58,6:5
7Comprehensive evaluation of the transformer oil-paper insulation state based on RF-combination weighting and an improved TOPSIS method显示文摘The accurate identification of the oil-paper insulation state of a transformer is crucial for most maintenance strategies.This paper presents a multi-feature comprehensive evaluation model based on combination weighting and an improved technique for order of preference by similarity to ideal solution(TOPSIS)method to perform an objective and scientific evaluation of the transformer oil-paper insulation state.Firstly,multiple aging features are extracted from the recovery voltage polarization spectrum and the extended Debye equivalent circuit owing to the limitations of using a single feature for evaluation.A standard evaluation index system is then established by using the collected time-domain dielectric spectrum data.Secondly,this study implements the per-unit value concept to integrate the dimension of the index matrix and calculates the objective weight by using the random forest algorithm.Furthermore,it combines the weighting model to overcome the drawbacks of the single weighting method by using the indicators and considering the subjective experience of experts and the random forest algorithm.Lastly,the enhanced TOPSIS approach is used to determine the insulation quality of an oil-paper transformer.A verification example demonstrates that the evaluation model developed in this study can efficiently and accurately diagnose the insulation status of transformers.Essentially,this study presents a novel approach for the assessment of transformer oil-paper insulation.Fugen Song Shichao Tong 2022Global Energy Interconnection2022,5,6:4

93-D Fracture Network Modelling in Hydropower Engineering Based on Optimal Monte Carlo Simulation显示文摘Effectively and accurately modelling the spatial relation of fracture surfaces is crucial in the design and construction of large hydropower dams having a complex underlying geology. However, fracture surfaces are randomly formed and vary greatly with respect to their spatial distribution, which makes the construction of accurate 3-D models challenging. In this study, we use an optimal Monte Carlo simulation and dynamic conditioning to construct a fracture network model. We found the optimal Monte Carlo simulation to effectively reduce the error associated with the Monte Carlo method and use dynamic conditioning to ensure the consistency of the model with the actual distribution of fractures on the excavation faces and outcrops. We applied this novel approach to a hydropower station on the Jinshajiang River, China. The simulation results matched the real sampled values well, confirming that the model is capable of effectively and accurately simulating the spatial relations in a fracture network.Pan Yue Denghua Zhong Fugen Yan Han Wu Yichi Zhang 2017Transactions of Tianjin University2017,23,4:2
