| 3 | STRESS ANALYSIS OF INJECTION MOLDED PARTS IN POST-FILLING STAGE显示文摘The linear isothermo-viscoelastic constitutive equation is established according to the principle of viscoelastic mechanics. Given the boundary conditions of the temperature field, the linear thermo-viscoelastic constitutive equation is established acording to the analysis of the thermorheologically simple. The stress analysis model is constructed on the base of some reasonable hypotheses which consider the restraint conditions of mold and the characteristics of injection molding in the post-filling stage. The mathematical model is calculated by the finite difference method. The results can help to predict the warpage of plastic products. | Jiang Tao Chen Xing Li Dequn (National Key ho of Plastic Simulation & Molding Technology Huazhong University of Science & Technology) | 2000 | Chinese Journal of Mechanical Engineering2000，13，1： | 5 |
| 4 | Study on modulation techniques free of orthogonality restriction显示文摘The Nyquist rate is a limit of transmission for traditional modulation methods from orthogonality restriction. Nonorthogonal modulation techniques (NMT) is proposed, which removes the orthogonality restriction, and as a result, higher bandwidth efficiency than the traditional methods can be achieved. First, the symbol error rate of NMT is introduced by using estimation theory. Then the relation between bandwidth efficiency and signal to noise ratio is discussed. Finally, a design instance of NMT is present and numerical experiment is made. This study explores for new modulation methods and points out a widened direction for modulation theory and applications. | CAO QiSheng LIANG DeQun | 2007 | Science in China(Series F)2007，50，6： | 4 |
| 5 | Modeling and simulation of residual stresses during glass bulb pressing process显示文摘The residual stresses accumulated in the forming process have great effects on the product quality of the glass bulb. Based on the characteristics analysis of glass bulb forming, a mathematical model has been established for calculating residual stresses of glass pressing process. The material is assumed as thermorheologi-cally simple thermoviscoelastic material, and the flow-induced stress is neglected. The consequences of equilibrium and compatibility equations are discussed in detail, and the boundary conditions are specified for various stages of the forming process. The numerical solution is based on the theory of thin layers, combined with finite difference method in the time and layer difference in the thickness di-rection. The presented model and solution method could easily be extended to general pressing process of glass, and applied to problems relative to glass pressing, providing extensive reference values. | ZHOU HuaMin, XI GuoDong & LI DeQun State Key Laboratory of Plastic Forming Simulation and Mold & Die Technology, Huazhong University of Science and Technology, Wuhan 430074 | 2007 | Science China(Technological Sciences)2007，50，1： | 4 |

| 7 | Precise carbon structure control by salt template for high performance sodium-ion storage显示文摘Carbon materials are considered to be one of the most promising anode materials for sodium-ion batteries(SIBs),but the well-ordered graphitic structure limits the intercalation of sodium ions.Besides,the sluggish intercalation kinetics of sodium ions impedes the rate performance.Thus,the precise structure control of carbon materials is important to improve the battery performance.Herein,a 3D porous hard-soft composite carbon(3DHSC)was prepared using the NaCl as the template and phenolic resin and pitch as carbon precursors.The NaCl template restrains the growth of the graphite crystallite during the carbonization process,resulting in small graphitic domains with expanded interlayer spacing which is favorable for the sodium storage.Moreover,the Na Cl templates help to create abundant mesopores and macropores for fast sodium ion diffusion.The porous structure and the graphite crystalline structure can be precisely controlled by simply adjusting the mass ratio of Na Cl,and thus,the suitable structure can be prepared to reach high capacity and rate performance while keeping a relatively high Coulombic efficiency.Typically,a high reversible capacity(215 mA h g^(-1)at 0.05 A g^(-1)),an excellent rate capability(97 mA h g^(-1)at 5 A g^(-1)),and a high initial Coulombic efficiency(60%)are achieved. | Dong Qiu Tengfei Cao Jun Zhang Si-Wei Zhang Dequn Zheng Haoliang Wu Wei Lv Feiyu Kang Quan-Hong Yang | 2019 | Journal of Energy Chemistry2019，28，4： | 3 |
| 8 | H_∞tracking design for a class of decentralized nonlinear systems via fuzzy adaptive observer显示文摘A novel H_∞tracking-based decentralized indirect adaptive output feedback fuzzy controller for a class of uncertain large-scale nonlinear systems is developed.By virtue of the proper filtering of the observation error dynamics,the observer-based decentralized indirect adaptive fuzzy control scheme is presented for a class of large-scale nonlinear systems using the combination of H_∞tracking technique,a fuzzy adaptive observer and fuzzy inference systems.The output feedback and adaptation mechanisms are both robust and implementable indeed owing to their freedom from the unavailable observation error vector.All the signals of the closed-loop largescale system are guaranteed to stay uniformly bounded and the output errors take on H_∞tracking performance. Simulation results substantiate the effectiveness of the proposed scheme. | Huang Yishao Zhou Dequn Chen Xiaoxin Du Lin | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 3 |
| 9 | THE PHASE-OFFSET OVERLAPPED WAVE TECHNIQUE显示文摘A new digital communication technology based on the Phase-Offset Overlapped Waves (POOW) has been introduced in this letter.The waves can be considered as a special multicarrier different from traditional ones.The sud-waves in a coded word's period of the POOW are sine waves and have the same frequencies,but different starting phases.The most important characteristic is that these sub-waves are the piecewise functions and not orthogonal in a code word period.The decoding can be implemented by solving a linear equation group.This code has very high efficiency and thus the data transmissin rate is increased greatly. | Liang Dequn (Dalian Maritime University, Dalian 116026)Liang Weihua (Dalian University of Science and Technology, Dalian 116026)Sun Changnian (Telecom Sino Group, Sunnyvale, California, USA, 94086) | 2003 | Journal of Electronics(China)2003，20，2： | 3 |
| 10 | Prized edible Asian mushrooms: ecology, conservation and sustainability显示文摘Mushrooms can be found in forests worldwide and have long been exploited as resources in developed economies because of their important agro-industrial,medicinal and commercial uses.For less developed countries,such as those within the Greater Mekong Subregion,wild harvesting and mushroom cultivation provides a much-needed alternative source of income for rural households.However,this has led to over-harvesting and ultimately environmental degradation in certain areas,thus management guidelines allowing for a more sustained approach to the use of wild mushrooms is required.This article addresses a selection of the most popular and highly sought after edible mushrooms from Greater Mekong Subregion:Astraeus hygrometricus,Boletus edulis,Morchella conica,Ophiocordyceps sinensis,Phlebopus portentosus,Pleurotus giganteus,Termitomyces eurhizus,Thelephora ganbajun,Tricholoma matsuake,and Tuber indicum in terms of value,ecology and conservation.The greatest threat to these and many other mushroom species is that of habitat loss and over-harvesting of wild stocks,thus,by creating awareness of these issues we wish to enable a more sustainable use of these natural products.Thus our paper provides baseline data for these fungi so that future monitoring can establish the effects of continued harvesting on mushroom populations and the related host species. | Peter E.Mortimer Samantha C.Karunarathna Qiaohong Li Heng Gui Xueqing Yang Xuefei Yang Jun He Lei Ye Jiayu Guo Huili Li Phongeun Sysouphanthong Dequn Zhou Jianchu Xu Kevin D.Hyde | 2012 | Fungal Diversity2012，，5： | 3 |

| 12 | The families Distoseptisporaceae fam.nov.,Kirschsteiniotheliaceae,Sporormiaceae and Torulaceae,with new species from freshwater in Yunnan Province,China显示文摘During a north–south latitudinal survey of aquatic fungi on submerged wood and herbaceous material in streams in the Asian region,we collected several hyphomycetous taxa.This paper is part of a series where we provide illustrated accounts of these taxa and place them in a natural classification in the fungi.DNA sequence based phylogenies in recent literature have shown that Dendryphion,Sporidesmium and Torula-like species are polyphyletic in the phylum Ascomycota and their taxonomyhas been problematic due to a lack of understanding of the importance of morphological characters used to delimit taxa,as well as the lack of ex-type or reference strains.Based on multi-locus phylogenies together with morphology,we propose the novel family Distoseptisporaceae(Sordariomycetes)and three novel genera Neotorula(Pleosporales,Dothideomycetes),Distoseptispora(Sordariomycetes)and Pseudosporidesmium(Sordariomycetes).In addition,Dendryphion aquaticum,D.submersum,Distoseptispora fluminicola,D.aquatica,Kirschsteiniothelia submersa,Neotorula aquatica,Sporidesmium aquaticum,S.submersum and S.fluminicola are introduced as new species.Pseudosporidesmium knawiae comb.nov.is proposed to accommodate Sporidesmium knawiae in Sordariomycetes.The polyphyletic nature of Dendryphion,Sporidesmium and Torula-like species are partially resolved,but further sampling with fresh collections and molecular data of species are needed to obtain a natural classification. | HongYan Su Kevin D.Hyde Sajeewa S.N.Maharachchikumbura Hiran A.Ariyawansa ZongLong Luo Itthayakorn Promputtha Qing Tian ChuanGen Lin QiuJu Shang YongChang Zhao HongMei Chai XiaoYing Liu Ali H.Bahkali Jayarama D.Bhat Eric H.C.McKenzie DeQun Zhou | 2016 | Fungal Diversity2016，，5： | 2 |
| 13 | Numerical Filling Simulation of Injection Molding Using Three-Dimensional Model显示文摘Most injection molded parts are three-dimensional, with complex geometrical configurations and thick/thin wall sections. A 3D simulation model will predict more accurately the filling process than a 2.5D model. This paper gives a mathematical model and numeric method based on 3D model, in which an equal-order velocity-pressure interpolation method is employed successfully. The relation between velocity and pressure is obtained from the discretized momentum equations in order to derive the pressure equation. A 3D control volume scheme is employed to track the flow front. Th e validity of the model has been tested through the analysis of the flow in cavity. | Geng Tie Li Dequn Zhou Huamin State Key Lab.of Mould & Die Technology, HuaZhong University of Science and Technology, Wuhan 430074,China | 2003 | Computer Aided Drafting,Design and Manufacturing2003，13，1： | 2 |
| 14 | Dynamic Changes,Regional Differences,and Influencing Factorsof CO_2 Emission Performance in China显示文摘This paper proposes to use DEA models with undesirable outputs to construct the Malmquist index that can be use to investigate the dynamic changes of CO 2 emission performance.With the index,the authors have measured the CO 2 emission performance of 28 provinces and autonomous regions in China from 1996 to 2007;with the convergence theory and panel data regression model,the authors analyze the regional differences and the influencing factors.It is found that the performance of CO 2 emissions in China has been continuously improved mainly due to the technological progress,and the average improvement rate is 3.25%,with a cumulative improvement rate of 40.86%.In addition,the CO 2 emission performance varies across four regions.As a whole,the performance score of eastern China is the highest.The northeastern and central China has relatively lower performance scores,and the western China is relatively backward.The regional differences are decreasing,and the performance of CO 2 emissions is convergent.The influence of some factors on the performance of CO 2 emissions is significant,such as the level of economic development,the level of industrial structure,energy intensity,and ownership structure.The influence of some factors,such as opening-up to the outside world,on the performance of CO 2 emissions is not significant.. | Wang Qunwei Zhou Peng Zhou Dequn | 2011 | Chinese Journal of Population,Resources and Environment2011，9，3： | 2 |

| 18 | Climate change effects fruiting of the prize matsutake mushroom in China显示文摘Climate change affects various facets of life but there is little data on its effects on wild mushroom fruiting.Yunnan Province in China is a rich source of wild mushrooms and has experienced a temperature rise over recent decades.This has resulted in warmer temperatures but the impacts of these changes on mushroom production lack documentation.We collected data on the fruiting of the highly prized matsutake mushroom(Tricholoma matsutake)in West Yunnan,China over an 11 year period from 2000 to 2010.Fruiting phenology and productivity were compared against the driving meteorological variables using Projection to Latent Structure regression.The mushrooms appeared later in the season during the observation period,which is most likely explained by rising temperatures and reduced rain during May and June.High temperature and abundant rain in August resulted in good productivity.The climate response of matsutake production results from a sequence of processes that are possibly linked with regulatory signals and resource availability.To advance the knowledge of this complex system,a holistic research approach integrating biology,ecology,genetics,physiology,and phytochemistry is needed.Our results contribute to a general model of fungal ecology,which can be used to predict the responses of fungi to global climate change. | Xuefei Yang Eike Luedeling Guangli Chen Kevin D.Hyde Youji Yang Dequn Zhou Jianchu Xu Yongping Yang | 2012 | Fungal Diversity2012，，5： | 1 |
