| 1 | Insulation Performance of CF3I-N2 Gas Mixtures as Alternative for SF6 in GIS/C-GIS显示文摘CF3I has been widely considered as a potential alternative for SF6,because it has low global warming potential(GWP)but an insulation capability that is 1.2 times greater than that of SF6.In this paper,the electron swarm parameters of CF3I and its gas mixture with N2,including the effective ionization coefficient and electron drift velocity,are examined theoretically through the Boltzmann equation method in the condition of steady-state Townsend(SST)experiments.Based on the derived data of the limiting field strength of CF3I-N2gas mixture,taking into consideration of environmental aspects such as GWP,ozone depletion potential(ODP),liquefaction temperature and toxicity,we studied the possibility of applying the gas mixture as the insulation medium in gas-insulated switchgears(GIS)or cubic type gas-insulated switchgears(C-GIS).It is found that CF3I-N2gas mixtures contained 30%~70%CF3I perform comprehensively better than pure SF6and compressed N2,and especially in medium and low voltage environments,the boiling point of CF3I-N2gas mixture meets the domestic and global requirements in mid-low latitude regions.Therefore we conclude that the gas mixture is acceptable for replacing SF6as the insulation medium in C-GISs. | DENG Yunkun XIAO Dengming CHEN Jiong | 2013 | 高电压技术2013，39，9： | 25 |
| 2 | Breakdown Properties of Nano-SiO2/LDPE Composite显示文摘聚合物纳米复合介质的击穿强度与纳米填充颗粒的质量分数、粒径和表面处理密切相关。以不同表面处理的纳米SiO2颗粒为填料,制备了不同填充质量分数、粒径的纳米SiO2/低密度聚乙烯(low density polyethylene,LDPE)复合介质,测试了其在交流、直流正极性和直流负极性3种不同类型电场下的击穿场强。结果表明:在所研究范围内,填充纳米SiO2颗粒可以提高低密度聚乙烯的击穿场强,并且随着填充质量分数的增加,复合介质的击穿场强有升高的趋势。纳米颗粒填充质量分数相同时,在12~16am粒径下,复合介质的击穿场强有随纳米SiO2粒径的升高而降低的趋势;在7nm小粒径下,可能由于纳米颗粒容易团聚,导致击穿场强较粒径大时要低。另外,纳米SiO2颗粒表面经疏水性处理后,能够有效提高复合介质的击穿场强。 | LAN Li WU Jiandong JI Zheqiang WANG Qiaohua LI Zhe XIAO Dengming YIN Yi | 2012 | 中国电机工程学报2012，32，13： | 14 |

| 4 | Discrete element simulation of localized deformation in stochastic distributed granular materials显示文摘The deformation in granular material under loading conditions is a problem of great interest currently. In this paper,the micro-mechanism of the localized deformations in stochastically distributed granular materials is investigated based on the modi-fied distinct element method under the plane strain conditions,and the influences of the confining pressure,the initial void ratio and the friction coefficient on the localized deformation and the stability of granular materials are also studied. It is concluded,based on the numerical simulation testing,that two crossed shear sliding planes may occur inside the granular assembly,and deformation patterns vary with the increasing of transverse strain. These conclusions are in good agreement with the present experimental results. By tangential velocity profiles along the direction normal to the two shear sliding planes,it can be found that there are two different shear deformation patterns: one is the fluid-like shear mode and the other is the solid-like shear mode. At last,the influences of various material parameters or factors on localized deformation features and patterns of granular materials are discussed in detail. | WANG DengMing ZHOU YouHe | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，9： | 6 |
| 5 | EGFR signaling augments TLR4 cell surface expression and function in macrophages via regulation of Rab5a activation显示文摘Dear Editor,oll-like receptor 4(TLR4)is a key receptor sensing bacterial lipopolysaccharide(LPS),and is the most investigated member of the Tol-like receptor family(Kawai and Akira,2007;Kayagaki et al,2013;Klein et al.,2015).Cell surface TLR4 expression is determined by the balance between receptor trafficking from the Golgi apparatus to the cell membrane,and internalization of the cell surface receptor into endosomal compartments(Saltoh,2009).In bone mar-row-derived macrophages(BMDM),we observed LPS-in-duced EGFR phosphorylation on the surface of BMDM,and this was inhibited by pretreatment with PD168393 or TAPI-1(Fig.S1).Next,we measured dynamic changes in cell sur-face TLR4 expression after LPS treatment.At6,12,and 24 h after LPS treatment,TLR4 expression on the surface of BMDM was increased^2-,~6-,and^9-fold,respectively,as compared with controls. | Jing Tang Bowei Zhou Melanie JScott Linsong Chen Dengming Lai Erica KFan Yuehua Li Qiang Wu Timothy RBilliar Mark AWilson Ping Wang Jie Fan | 2020 | Protein & Cell2020，11，2： | 2 |
| 6 | MULTISCALE MECHANICAL BEHAVIORS IN DISCRETE MATERIALS: A REVIEW显示文摘The discrete material,which belongs to the category of soft materials,is one of the most prevalent forms of matter in nature and engineering fields.These materials often exhibit abundant and complex mechanical properties which are still far from being perfectly understood.From the view of multi-scale framework concentrated on the ‘bridge’ role in the macro-micro relation,this review mainly introduces some theoretical investigations of mechanical behaviors in discrete materials,including the continuum constitutive model based on the macroscopic phe-nomenological approach and coupled micro-macro approach,the statistical analysis of some micro-scopic physical quantities involved contacted forces between particles and its transmission within the whole system,and the statistical analysis for some microscopic processes in aeolian landform systems involving the grain-bed impact,the transportation and sedimentation of wind-blown sand flux,et al.Finally,some further worthwhile challenges in these fields are suggested. | Xiaojing Zheng Dengming Wang (Key Laboratory of Mechanics on Western Disaster and Environment,the Ministry of Education of China,Lanzhou University,Lanzhou 730000,China) | 2010 | Acta Mechanica Solida Sinica2010，23，6： | 2 |
| 7 | 丝路咽喉——河西走廊显示文摘河西走廊,地处甘肃西部黄河以西。南与青藏高原北缘的祁连山脉接壤,东临黄土高原,西与塔里木盆地交界,北与内蒙古高原南缘隆起的北山山地相连,是一条长1000多公里、宽数公里至百余公里的狭长地带,因形似走廊而得名。
特殊的地理位置赋予河西走廊重要的历史职能。河西走廊虽然处于峰峦叠嶂的祁连山和主要为戈壁、沙漠的内蒙古高原的夹峙之下,但走廊之上,却是绿洲相连,地下水源充沛,资源丰富,物产富饶,自古以来即为中原通西域的首选之路。自3000多年前起,河西走廊就成为中国内地通往西域地区的必经通道,神秘的“玉石之路”和周穆王西巡,沟通了中原与西域地区的联系。自公元前121年开始,成为闻名于世的丝绸之路的主干路段。由于历史的原因,这里成为华夏文明与两河文明、印度文明、地中海文明的交汇区。正是在东西方文明的交流融会过程中,河西走廊得以长期吸纳这条道路上荟萃的各种文明,促进了自身经济、文化的繁荣和发展,并形成了独特的河西文化。 | 邵如林 Zhao Dengming | 2014 | 丝绸之路2014，，11： | 2 |
| 8 | Magnetic properties and microstructure of nanocrystalline bulk Nd-Fe-B with Ce-Co addition显示文摘The influence of Ce-Co alloy addition and sintering holding time on permanent magnetic properties and micro structure of nanocrystalline Nd-Fe-B bulk alloy were investigated.The coercivity of Nd-Fe-B bulk alloy can be enhanced greatly by more than 100% after adding Ce-Co powders.However,when the concentration of Ce-Co is up to 30 wt%,the density of the magnet can reach the maximum value of 7.58 g/cm^(3),but the coercivity does not increase significantly.On the other hand,with the increase of holding time to 10 min,the density and coercivity of magnets increase gradually,reaching up to 7.55 g/cm^(3) and 1134.3 kA/m,respectively.After the addition of Ce-Co alloy,Ce-Co may easily diffuse into the Nd-Fe-B matrix during hot-pressing and under the high pressure and temperature,thus increasing the content of grain boundary phase and the pinning effect of grain boundary,which leads to the increase of coercivity.The extension of the hot-pressing holding time may be more conducive to the diffusion of CeCo into the Nd-Fe-B matrix.In addition,the effect of Ce-Co addition on the magnetic properties of Nd-FeB with different content of rare earth was also studied.The addition of Ce-Co can effectively increase the coercivity of nanocomposite Nd_(2)Fe_(14)B/α-Fe magnets.The addition of Nb to the parent alloy can further improve the coercivity.For Nd_(11)Fe_(81.5)Nb_(1)Ga_(0.5)B_(6) alloy with 10 wt% Ce-Co addition,the coercivity can increase from 740.28 to 1098.48 kA/m. | Yilong Ma Qiqi Yang Xiaoli Chen Ying He Wenbo Xiang Jiaqi Lai Bin Shao Donglin Guo Dengming Chen Kejian Li | 2021 | Journal of Rare Earths2021，39，6： | 1 |

| 12 | Numerical simulation on directional solidification of Al-Ni-Co alloy based on FEM显示文摘The ratio,of the temperature gradient at the solidifiationfront to the solidification rate of solid-liquid interface,plays a large part in columnar grain growth.The transient temperature fields of directional solidification of Al-Ni-Co alloy were studied by employing a finite element method.The temperature gradient at the solidification front and the solidification rate were analyzed for molten steels pouring at different temperatures.The results show that with different initial pouring temperatures,the individual ratio of the temperature gradient at solidification front to the solidification rate soars up in the initial stage of solidification,then varies within 2,000-6,000℃.s.cm-2,and finally goes down rapidly and even tend to be closed to each other when the solidification thickness reaches 5-6 cm.The simulation result is consistent with the practical production which can provide an available reference for process optimization of directional solidified Al-Ni-Co alloy. | Yang Zhili Chen Dengming Tian Shilong, Liao Daohan Yang Yu | 2010 | China Foundry2010，7，1： | 1 |
