| 1 | Influence of tectonic stress on coalification:Stress degradation mechanism and stress polycondensation mechanism显示文摘The function of pressure for coalification is a long-term controversial issue, and the main cause is that the strata pressure and the tectonic stress were confused, which are two different actions of 'pres-sure' . The former benefits the physical coalification but retards the chemical coalification, whereas the latter may not only affect the physical structure of coal but also promote its chemical composition changes. In accordance with the organic molecule evolution of coal, there are two kinds of basic mechanisms of the influence of the tectonic stress on the chemical coalification: the tectonic stress degradation and the tectonic stress polycondensation. The stress degradation mechanism is a process of that, when the tectonic stress acted on the large molecule of coal in the form of mechanical force or kinetic energy, some chemical bonds of low decomposed energy, such as aliphatic side-chain and oxygenic functional groups, were broken up and then were degraded into free radicals of less mo-lecular weight, and finally escaped from coal in the form of liquid organic matter (hydrocarbon). The stress polycondensation is considered that, under the control of the anisotropic tectonic stress, the condensed aromatic nucleus trend to be parallel arranged and to be enhanced through rotating or displacing of aromatic rings, the basic structural unit of coal (BSU) increases by directional develop-ment and preferential stack. X-ray diffraction (XRD), Fourier transformation infrared microspectroscopy (FTIR), and rock pyrolysis analysis (Rock-eval) were employed to study the deformed coal series and the non-deformed coal series. The results showed that, compared with the non-deformed coal, the de-formed coal exhibits particular characteristics: weaker aliphatic absorbance peak and stronger aro-matic absorbance peak, lower pyrolysed hydrocarbon yield, and more increscent BSU. The concepts of stress degradation mechanism and stress polycondensation mechanism presented here would not deny the dominant function of the temperature in coalification, but emphasize the 'catalysis' of the tectonic stress in coalification. | CAO DaiYong LI XiaoMing ZHANG ShouRen | 2007 | Science China Earth Sciences2007，50，1： | 36 |

| 3 | Commentary of research situation and innovation frontier in hydro-structure engineering science显示文摘In order to utilize water and hydropower resources in China,multitudes of water projects are established or to be constructed as an integral part of the national economy's infrastructure.Under these circumstances,there are two outstanding problems:1) a mass of existing dams are in danger and 2) in the southwest water-conservancy construction plan,dozens of existing or planned dams are high dams or even super high dams with heights between 200 and 300 m.In accordance with demands of 'the National Program for Medium-and Long-Term Scientific and Technological Development' on the innovation frontier in hydro-structure engineering science,various key problems in science and technology such like stress analysis,ultimate bearing capacity,nonlinearity etc.for high dams,super high dams and sick dams have been investigated.This paper makes a commentary on the advances and results of the researches,then analyzes the advantages and disadvantages of current theoretics and methodologies,and finally presents corresponding research directions and the frontier of innovation. | WU ZhongRu PENG Yan LI ZhanChao LI Bo YU Hong ZHENG ShouRen | 2011 | Science China(Technological Sciences)2011，54，4： | 14 |
| 4 | Deformation Behavior and Microstructure Evolution of Wrought Magnesium Alloys显示文摘There are many researches on the deformation behavior of wrought magnesium alloys, such as AZ31, AZ80, AZ91, and ZK60 magnesium alloys at different temperatures and strain rates, but few of them focuses on the deformation behavior of AZ41M and ZK60M alloys, especially under the twin-roll casting (TRC) state. Meanwhile, the existing researches only focus on the grain refinement law of the magnesium alloys under deformation conditions, the deformation mechanism has not been revealed yet. The hot compression behavior of AZ41M and ZK60M magnesium alloys under the temperature and strain rate ranges of 250-400 ℃ and 0.001-1 s-1 are studied by thermal simulation methods using Gleeble 1500 machine and virtual simulation using finite element analysis software. Simulation results show that sine hyperbolic law is the most suitable flow stress model for wider deformation conditions. The most reasonable selected deformation conditions of ZK60M alloy is 350 oC/0.1 s-1 for TRC and 350 oC/1 s-1 for conventional casting (CC), while AZ41M alloy is 300 oC/0.01 s-1 for TRC and 350 oC/0.1 s-1 for CC. Deformation behavior and dynamic recrystallization (DRX) mechanism of them are analyzed at the same deformation conditions. The microstructures of AZ41M and ZK60M alloys are observed at different deformed conditions by optical microscopy (OM) and electron back scatter diffraction (EBSD) and it reveals the flow behavior and deformation mechanism of them. Working harden and work soften contribute to the activation of basal, non-basal slip systems which promote DRX. The proposed research reveals the deformation behavior and mechanism of the AZ41M and ZK 60M magnesium alloys and concludes their optimized deformation parameters and processes and provides a theory basis for their manufacturing and application. | WANG Shouren SONG Linghui KANG Sukbong CHO Jaehyung WANG Yingzi | 2013 | Chinese Journal of Mechanical Engineering2013，26，3： | 9 |
| 5 | Design principles and parameters of rice ideal panicle type显示文摘On the basis of many years of research at the laboratory, and by making reference to the related literature published at home and abroad, in this paper the concept of rice ideal panicle type was introduced, and the principles of rice ideal panicle type design were elucidated. The parame-ters of rice ideal panicle type for Liaoning were preliminarily established as follows: Panicle length <17 cm, neck-panicle curvature <40°, neck panicle length 3―4 cm, neck diameter >2 mm, large vascular bundle and primary branch >15 pieces/panicle, primary branch grain >80 grains/panicle, secondary branch grains concentrating in the middle and upper parts of panicle axis, and panicle type index >0.5. In addition, the possibility of achieving unity of grain yield and quality at a still higher level by creating an ideal panicle type was explored. | XU Zhengjin CHEN Wenfu ZHANG Longbu YANG Shouren | 2005 | Chinese Science Bulletin2005，50，19： | 6 |
| 6 | Cephalopods of the “Falang Formation” (Triassic) from Guanling and Zhenfeng Counties, Guizhou Province, China显示文摘The 'Falang Formation' of western Guizhou was previously called the 'Halobia Bed' and considered to beLadinian in age. It was subdivided upward into the Zhuganpo, Laishike and Longchang members based on ammonites andthe Trachyceras multitubertulatum Zone of the Longchang Member was put in the Lower Carnian. Here in the presentpaper, 4 genera and 9 species of ammonites and 1 nautiloid genus and species collected from the upper part of the 'FalangFormation' (i.e. the Wayao Formation used in this paper, equivalent to the Laishike Member from Guanling and Zhenfengcounties are described. The geological and geographical distribution of these cephalopods, as well as the co-existingconodonts, put the Wayao Formation to the late early Carnian. | HAO Weicheng, SUN Yuanlin, JIANG Dayong, YANG Shouren and WANG Xinping Geological Museum, Peking University, Beijing 100871 | 2003 | Acta Geologica Sinica(English Edition)2003，77，4： | 5 |
| 7 | Effect of crystallization of CaO-P_2O_5-SiO_2-MgO-F^- glass-ceramics on its mechanical properties显示文摘The microstructure of CaO-P2O5-SiO2-MgO-F glass-ceramics during crystallization were investigated and the crystallized phases were identified with DTA (Differential Thermal Analysis), SEM (Scanning Electron Microscope) and XRD (X- ray Diffraction) techniques. The mechanical properties such as bending strength and fracture toughness, as well as their changes with advancing crystallization were determined. The results show that the changes of the mechanical properties are correlated with the microstructures. The sample heated up to 810℃ and soaked for 4h has smaller crystalline size and less volum fraction of fluorophlogopite, so it has higher bending strength (about 190 MPa), and higher crack toughness (about 2.63 MPa·m12). | Bing Yu, Kaiming Liang, and Shouren GuDepartment of Materials Science and Engineering, Tsinghua University, Beijing 100084, China (Received 2001-12-06) | 2002 | Journal of University of Science and Technology Beijing2002，9，3： | 4 |
| 8 | Effect of Phosphorus on Mechanical Properties and Thermal Stability of Fine-grained GH761 Alloy显示文摘The effect of phosphorus on mechanical properties and thermal stability of fine-grained GH761 alloy has been investigated.The results show that,when the content of phosphorus is in the range of 0.0007-0.040,there are no significant effects on the tensile properties.Phosphorus strongly affects the stress rupture life.The content of 0.023 P results in the longest life in this experiment.Compared with that of the alloy with 0.0007 P,the life is increased more than 2 times in the alloy with 0.023 P.After ageing at 700℃ for 1000 h,the life reduced to some extent.However,phosphorus exhibits the similar effect on the life as before ageing.The tensile properties of the alloy are not influenced by long term ageing obviously.The present results suggested that the optimum content of phosphorus is 0.023.The phosphorus with this content can optimize the precipitates at the grain boundaries and prevent the excessive growth of the precipitates.The combining mechanical properties of GH761 alloy can be largely improved by phosphorus addition combined with grain refinement. | Shulin Yang Wenru Sun Jianxi Wang Zhimei Ge Shouren Guo Zhuangqi Hu | 2011 | Journal of Materials Science & Technology2011，27，6： | 3 |
| 9 | Role of P,S and B on Creep Behavior of Alloy 718显示文摘The doping of phosphorus, sulfur and boron in IN718 superalloy can remarkably influence the creep behavior. The modifications of the minor elements seem not to vary the stress exponent and the influences primarily concentrate on the effective diffusion coefficient. A pronounced beneficial interaction between P and B and a weaker detrimental interaction between P and S have been obtained. The preexponential frequency constant is proved to be strongly related with the creep activation energy because of the so-called compensation effect. The compensation temperature has been determined to be about 1080 K, which corresponds to the transformation temperature from rapidly coarsened γ’’ phase to δ phase. It has been proposed that trace elements can influence the effective diffusion coefficient individually or cooperatively, which in turn either retard or speed the creep process. | Zhuangqi HU, Hongwei SONG, Shouren GUO and Wenru SUN Institute of Metal Research, The Chinese Academy of Sciences, Shenyang 110016, China | 2001 | Journal of Materials Science & Technology2001，17，4： | 3 |
| 10 | Effect of Testing Conditions on Fibre-Bundle Tensile Properties Part Ⅰ: Sample Preparation, Bundle Mass and Fibre Alignment of Wool Bundles显示文摘Due to the effects of samples and testing conditions on fibre-bundle tensile behaviour, it is necessary to investigate the relationships between experimental factors and tensile properties for the fibre-bundle tensile tester (TENSOR). The effects of bundle sample preparation, fibre bundle mass and fibre alignment have been tested. The experimental results indicated that (1) the low damage in combing and no free-end fibres in the cut bundle are most important for the sample preparation; (2) the reasonable bundle mass is 400700 tex, but the tensile properties measured should be modified with the bundle mass because a small amount of bundle mass causes the scatter results, while the larger is the bundle mass, the more difficult to comb fibres parallel and to clamp fibre evenly; and (3) the fibre irregular arrangement forms a slack bundle resulting in interaction between fibres, which will affect the reproducibility and accuracy of the tensile testing. | 于伟东 严灏景 Ron Postle Yang Shouren | 2002 | Journal of Donghua University(English Edition)2002，19，2： | 3 |
| 11 | Coarse root spatial distribution determined using a ground-penetrating radar technique in a subtropical evergreen broad-leaved forest,China显示文摘Coarse roots play a critical role in forest ecosystems and both abiotic and biotic factors affect their spatial distribution.To some extent,coarse root density may reflect the quantity of root biomass and biotic competition in forests.However,using traditional methods(e.g.,excavation)to study coarse roots is challenging,because those methods are time-consuming and laborious.Furthermore,these destructive methods cannot be repeated in the same forests.Therefore,the discovery of non-destructive methods for root studies will be very significant.In this study,we used a ground-penetrating radar technique to detect the coarse root density of three habitats(ridge,slope and valley)and the dominant tree species(Castanopsis eyrei and Schima superba)in a subtropical forest.We found that(i)the mean of coarse root density for these three habitats was 88.04roots m–2,with roots being mainly distributed at depths of 0–40 cm.Coarse root densities were lower in deeper soils and in areas far from the trunk.(ii)Coarse root densities differed significantly among the three habitats studied here with slope habitat having the lowest coarse root density.Compared with S.superba,C.eyrei had more roots distributed in deeper soils.Furthermore,coarse roots with a diameter>3 cm occurred more frequently in the valleys,compared with root densities in ridge and slope habitats,and most coarse roots occurred at soil depths of 20–40 cm.(iii)The coarse root density correlated negatively with tree species richness at soil depths of 40–60 cm.The abundances of the dominant species,such as C.eyrei,Cyclobalanopsis glauca,Pinus massoniana,had significant impacts on coarse root density.(iv)The soil depth of 0–40 cm was the'basic distribution layer'for coarse roots since the majority of coarse roots were found in this soil layer with an average root density of 84.18 roots m–2,which had no significant linear relationships with topography,tree species richness,rarefied tree species richness and tree density.Significant relationships between coarse root density and these factors were found at the soil depth of40–60 cm,which was the'potential distribution layer'for coarse root distribution. | YAN Hui DONG XinLiang FENG Gang ZHANG ShouRen MUCCIARDI Anthony | 2013 | Science China(Life Sciences)2013，56，11： | 3 |
| 12 | Fabrication and abrasive wear properties of metal matrix composites reinforced with three-dimensional network structure显示文摘Reticulated polyurethane was chosen as the preceramic material for preparing the porous preform using the rep- lication process. The immersing and sintering processes were each performed twice for fabricating a high-porosity and su- per-strong skeleton. The aluminum magnesium matrix composites reinforced with three-dimensional network structure were prepared using the infiltration technique by pressure assisting and vacuum driving. Light interfacial reactions have played a profitable role in most of the ceramic-metal systems. The metal matrix composites interpenetrated with the ceramic phase have a higher wear resistance than the metal matrix phase. The volume fraction of ceramic reinforcement has a sig- nificant effect on the abrasive wear, and the wear rate can be decreased with the increase of the volume fraction of rein- forcement. | WANG Shouren GENG Haoran LI Kunshan SONG Bo WANG Yingzi HUI Linhai | 2006 | Rare Metals2006，25，6： | 2 |
| 13 | Microstructure and hot compression behavior of twin-roll-casting AZ41M magnesium alloy显示文摘The relationship of true stress and true strain of AZ41M magnesium alloy under twin-roll-cast(TRC) and hot compression was analyzed using a Gleeble 1500 machine.Microstructural evolutions of the TRC magnesium alloy under different deformation conditions(strain,strain rate and deformation temperature) were examined using optical microscopy and discussed.The relationship of true stress and true strain predicted that lower deformation temperature and higher strain rate caused sharp strain hardening.Meanwhile,the flow stress curve turned into a steady state at high temperature and lower strain rate.The intermediate temperature and strain rate(623 K and 0.01 s-1) is appropriate. | WANG Shouren WANG Min MA Ru WANG Yong WANG Yanjun | 2010 | Rare Metals2010，29，4： | 2 |
| 14 | Effect of Phosphorus on Stress Rupture Properties of GH4133 Ni-Base Superalloy显示文摘The effect of phosphorus on the stress rupture property of GH4133 alloy has been investigated and is compared with that of IN718 alloy. The GH4133 alloy is crept by dislocation movement. Phosphorus has a tendency to prolong the rupture life of some wrought superalloys by inhibiting the dislocation movement. If the phosphorus addition is too high, its effect on impairing the grain boundary cohesion overwhelms that on inhibiting the dislocation movement,and the life of the GH4133 alloy can be shortened. The two functions of inhibiting the dislocation movement and impairing the grain boundary cohesion determine that the optimum phosphorus content in the GH4133 alloy is around 0.011 wt pct. Phosphorus exhibits a greater effect on prolonging the rupture life of IN718 alloy than that of GH4133alloy. The two alloys are crept by different mechanisms. The intergranular phosphorus-bearing phase is precipitated in the IN718 alloy, while not in the GH4133 alloy. The precipitation of the phosphorus bearing phase can balance the phosphorus segregation at the grain boundaries and allows a more remarkable effect of phosphorus on extending the rupture life of IN718 alloy. | Wenru SUN+, Shouren GUO, Baiyun TONG, Dezhong LU, Yan XU, Xiaona MENG, Na LI and Zhuangqi HUDepartment of Superallovs, Institute of Metai Research, Chinese Academy of Sciences, Shenyang 110016, China | 2003 | Journal of Materials Science & Technology2003，19，4： | 2 |
| 15 | Regulating electronic structure of two-dimensional porous Ni/Ni_(3)N nanosheets architecture by Co atomic incorporation boosts alkaline water splitting显示文摘Interfacial engineering is a powerful method to improve the bifunctional electrocatalytic performance of pure phase catalysts.While it is expected to further optimize the electronic configuration of heterojunctions to boost the reaction kinetics in hydrogen/oxygen evolution reaction(HER/OER),but remains a challenge.Herein,a novel in situ hybrid heterojunction strategy is developed to construct 2D porous Co-doped Ni/Ni_(3)N heterostructure nanosheets(Co-Ni/Ni_(3)N)by pyrolysis of partially cobalt substituted nickel-zeolitic imidazolate framework(CoNi-ZIF)nanosheets under NH3 atmosphere.A combined experimental and theoretical studies manifest that the hybrid heterostructures can display regulative electronic states and downshift d-band center from the Fermi level,as well as optimize the adsorption energy of reaction intermediates,thus reducing the thermodynamic energy barriers and accelerating the catalytic kinetics.Consequently,benefitting from the optimized electronic configuration,hierarchical hollow nanosheets architecture,and abundant doped heterojunctions,the hybrid Co-Ni/Ni_(3)N heterostructure catalyst exhibits efficient catalytic activity for both HER(60 mV)and OER(322 mV)at 10 mA cm^(-2)in alkaline media,which is 105 and 47 mV lower than that of pure Ni_(3)N,respectively.The electrochemically active surface area of Co-Ni/Ni_(3)N is two times higher than that of Ni3N.Furthermore,the coupled practical water electrolyzer requires a low voltage of 1.575 V to reach 10 mA cm^(-2),and it can be driven by a 1.5 V battery.This work highlights the interface engineering guidance for the rational establishment of hybrid interfaces by electronic modulation of interfacial effect for alkaline water splitting. | Kaixi Wang Yingying Guo Zhonghui Chen Donghai Wu Shouren Zhang Baocheng Yang Jianan Zhang | 2022 | InfoMat2022，4，6： | 1 |
