| 1 | Behavior of composite rigid frame bridge under bi-directional seismic excitations显示文摘Pushover analysis and time history analysis are conducted to explore the bi-directional seismic behavior of composite steel-concrete rigid frame bridge,which is composed of RC piers and steel-concrete composite girders.Both longitudinal and transverse directions excitations are investigated using OpenSees.Firstly,the applicability of pushover analysis based on the fundamental mode is discussed.Secondly,an improved pushover analysis method considering the contribution of higher modes is proposed,and the applicability on composite rigid frame bridges under bi-directional earthquake is verified.Based on this method,an approach to predict the displacement responses of composite rigid frame bridge under random bi-directional seismic excitations by revising the elasto-plastic demand curve is also proposed.It is observed that the developed method yield a good estimate on the responses of composite rigid frame bridges under bi-directional seismic excitations. | Xiaogang Liu Jiansheng Fan Jianguo Nie Guo Li | 2014 | Journal of Traffic and Transportation Engineering(English Edition)2014,1,1: | 22 |

| 3 | Ground Surface Ruptures and Near-Fault,Large-Scale Displacements Caused by the Wenchuan Ms8.0 Earthquake Derived from Pixel Offset Tracking on Synthetic Aperture Radar Images显示文摘The 12 May 2008 Wenchuan Ms8.0 earthquake produced surface displacements along the causative fault,the Yingxiu-Beichuan Fault,which are up to several meters near the fault.Because of the large gradient,satellite synthetic aperture radar(SAR) interferometric data are strongly incoherent;the usual SAR interferometry method does not allow such displacements to be measured.In the present study,we employed another approach,the technique based on pixel offset tracking,to solve this problem.The used image data of six tracks are from the Advanced Land Observing Satellite,Phased Array type L-band Synthetic Aperture Radar(ALOS/PALSAR) dataset of Japan.The results show that the entire surface rupture belt is 238 km long,extending almost linearly in a direction of 42° north-east.It is offset left laterally by a north-west-striking fault at Xiaoyudong,and turns at Gaochuan,where the rupture belt shifts toward the south by 5 km,largely keeping the original trend.In terms of the features of the rupture traces,the rupture belt can be divided into five sections and three types.Among them,the Beichuan-Chaping and Hongkou-Yingxiu sections are relatively complex,with large widths and variable traces along the trend.The Pingtong-Nanba and Qingping-Jingtang sections appear uniform,characterized by straight traces and small widths.West of Yingxiu,the rupture traces are not clear.North of the rupture belt,surface displacements are 2.95 m on average,mostly 2-3.5 m,with 7-9 m the maximum near Beichuan.South of the rupture belt,the average displacement is 1.75 m,dominated by 1-2 m,with 3-4 m at a few sites.In the north,the displacements in the radar line of sight are of subsidence,and in the south,they are uplifted,in accordance with a right-slip motion that moves the northern wall of the fault to the east,and the southern wall to the west,respectively.Along the Guanxian-Jiangyou Fault,there is a uplift zone in the radar line of sight,which is 66 km long,1.5-6 km wide,and has vertical displacements of approximately 2 m,but no observable rupture traces. | QU Chunyan SHAN Xinjian LIU Yunhua ZHANG Guohong SONG Xiaogang ZHANG Guifang GUO Liming HAN Yufei | 2012 | Acta Geologica Sinica(English Edition)2012,86,2: | 10 |
| 4 | Response of leaf photosynthetic characteristics of Syringa oblata and Syringa reticulata var.mandshurica to chilling stress显示文摘Syringa species not only have good ornamental properties but also play an important role in the landscaping and environmental purification of cities.To investigate the chilling stress resistance of Syringa oblata Lindl.and Syringa reticulata var.mandshurica and provide theoretical grounds for the practical cultivation of Syringa species,in vitro leaves were used to study photosynthetic gas exchange parameters and chlorophyll fluorescence parameters.After nine hours of chilling,decreasing rates of net photosynthesis,stomatal conductance,and transpiration in S.reticulata var.mandshurica leaves were significantly greater than that of the S.oblata,while intercellular CO2 concentrations in S.oblata leaves were higher than those in S.reticulata var.mandshurica.The quantum yield of PSII reaction center(APSII)declined in S.reticulata and light capture efficiency(Fv 0/Fm 0)was stable.However,reduction percentages of Fv 0/Fm 0,APSII,and Fv/Fm in S.oblata were significant higher than those of S.reticulata var.mandshurica.After nine hours of chilling,the relative variable fluorescence of VJ and VI of S.oblata increased and the increasing rate of VJ was greater than VI.In contrast,the change of VJ and VI in S.reticulata var.mandshurica leaves was relatively small.This suggests that chilling primarily damaged the electron transport process of QA to QB at the receptor site of the PSII reaction center.Photosynthetic capacity of S.oblata was more sensitive to chilling stress compared to S.reticulate var.mandshurica,which the limitations were mainly due to non-stomatal factors such as the decrease in electron transport efficiency,activity in the PSII reaction center,and the destruction of the photodamage defense system. | Xiaojia Liu Baiyi An Na Gu Cainan Guo Xiaogang Sun He Wang | 2020 | Journal of Forestry Research2020,31,2: | 8 |
| 5 | Numerical study on the restriction speed of train passing curved rail in cross wind显示文摘The results of numerical investigations of aerodynamic forces and moment coefficients of flow passing a simplified train geometry under different wind speeds are summarized. To compute numerically the different coefficients, the three-dimensional Reynolds-Averaged Navier-Stokes (RANS) equations, combined with the k-ε turbulence model, were solved using finite volume technique. The pres-sure-velocity fields were coupled using the SIMPLE algorithm. At each iteration the pressure correction was obtained by solving a velocity divergence-derived Poisson-like equation. With the computed aerodynamic forces, the formula of the restriction speed at which the train passed curved rail in cross wind was deduced to analyse the influences of aerodynamic forces on the restriction speed. Results of numerical investigations showed that aerodynamic lift and overturn moment increased more and more rapidly with train speed and wind speed. The enhancement trends showed nonlinear phenomena and enhanced risk in the course of train movement. When the train travels at a high speed and encounters a huge cross wind, the influence involved by nonlinear risk increment will extremely impair safety of train. The following conclusion can also be drawn: The effect of aerodynamic lift makes restriction speed reduce, however, the influences of aerodynamic drag to the limit train speed rest on the direction of wind flow. When the wind blows from inner rail to outer rail, aerodynamic forces shall reduce the restriction speed, by contraries, when the wind blows from outer rail to inner rail, aerodynamic forces shall increase the restriction speed. | CHEN RuiLin ZENG QingYuan ZHONG XinGu XIANG Jun GUO XiaoGang ZHAO Gang | 2009 | Science China(Technological Sciences)2009,52,7: | 8 |
| 6 | Factors affecting genomic selection revealed by empirical evidence in maize显示文摘Genomic selection(GS) as a promising molecular breeding strategy has been widely implemented and evaluated for plant breeding, because it has remarkable superiority in enhancing genetic gain, reducing breeding time and expenditure, and accelerating the breeding process. In this study the factors affecting prediction accuracy(rMG) in GS were evaluated systematically, using six agronomic traits(plant height, ear height, ear length, ear diameter,grain yield per plant and hundred-kernel weight) evaluated in one natural and two biparental populations. The factors examined included marker density, population size, heritability,statistical model, population relationships and the ratio of population size between the training and testing sets, the last being revealed by resampling individuals in different proportions from a population. Prediction accuracy continuously increased as marker density and population size increased and was positively correlated with heritability; rMGshowed a slight gain when the training set increased to three times as large as the testing set. Low predictive performance between unrelated populations could be attributed to different allele frequencies, and predictive ability and prediction accuracy could be improved by including more related lines in the training population. Among the seven statistical models examined, including ridge regression best linear unbiased prediction(RR-BLUP), genomic BLUP(GBLUP), Bayes A, Bayes B, Bayes C, Bayesian least absolute shrinkage and selection operator(Bayesian LASSO), and reproducing kernel Hilbert space(RKHS), the RKHS and additive-dominance model(Add + Dom model) showed credible ability for capturing non-additive effects, particularly for complex traits with low heritability. Empirical evidence generated in this study for GS-relevant factors will help plant breeders to develop GS-assisted breeding strategies for more efficient development of varieties. | Xiaogang Liu Hongwu Wang Hui Wang Zifeng Guo Xiaojie Xu Jiacheng Liu Shanhong Wang Wen-Xue Li Cheng Zou Boddupalli M.Prasanna Michael S.Olsen Changling Huang Yunbi Xu | 2018 | The Crop Journal2018,6,4: | 8 |
| 7 | Electro-mechanically controlled assembly of reconfigurable 3D mesostructures and electronic devices based on dielectric elastomer platforms显示文摘The manufacture of 3D mesostructures is receiving rapidly increasing attention,because of the fundamental significance and practical applications across wide-ranging areas.The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials;with feature sizes spanning nanoscale to centimeter-scale.Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates;which limits the capabilities to achieve on-demand local assembly;and to reshape assembled mesostructures into distinct 3D configurations.This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly.Capabilities of sequential-local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries,as demonstrated by experimental and theoretical studies of?30 examples.A reconfigurable inductive-capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example. | Wenbo Pang Xu Cheng Haojie Zhao Xiaogang Guo Ziyao Ji Guorui Li Yiming Liang Zhaoguo Xue Honglie Song Fan Zhang Zheng Xu Lei Sang Wen Huang Tiefeng Li Yihui Zhang | 2020 | National Science Review2020,7,2: | 8 |
| 8 | BARRIER LAYER IN THE NORTHEASTERN SOUTH CHINA SEA AND ITS FORMATION MECHANISM显示文摘Robust evidence for the barrier layer (BL) in the northeastern South China Sea (SCS) (16°-25°N, 112°-124°E) is presented. The occurrence rate of the BL peaks in the autumn (45.7%) and then the summer (31.1%) and the spring (23.3%), se-quently. It is estimated that the annual occurrence rate of the BL reaches about 40.0% in the central northeastern SCS (18°-22°N, 112°-120°E) and the Luzon Strait. Stratification-formed (Rain-formed) mechanism is the major factor responsible for the occurrence of the BL in the northeastern SCS in the spring (the summer and autumn), respectively. The rainfall observation from TRMM provides reliable evidence for the latter. | PAN Aijun WAN Xiaofang XU Jindian GUO Xiaogang LI Li | 2006 | Chinese Science Bulletin2006,51,4: | 7 |
| 9 | Seasonal variation of surface currents in the southwestern Taiwan Strait observed with HF radar显示文摘Long-term measurements from a pair of High-Frequency radar systems deployed near the coast of southern Fujian Province showed that surface currents in the southwestern Taiwan Strait were com-posed mainly of the monsoon-driven, seasonal fluctuation of longshore current and a persistent northeastward background flow with speeds around 10 cm/s. Measurements from bottom-moored ADCPs further indicated that below the surface Ekman layer longshore currents also directed to the north all year round. | ZHU DaYong LI Li LI Yan GUO XiaoGang | 2008 | Chinese Science Bulletin2008,53,15: | 7 |
| 10 | The effects of Haversian fluid pressure and harmonic axial loading on the poroelastic behaviors of a single osteon显示文摘In order to well understand the mechanism of the mechanotransduction in bone,we propose a new model of transverse isotropic and poroelastic osteon cylinder considering Haversian fluid pressure.The analytical pore pressure and velocity solutions are obtained to examine the fluid transport behavior and pressure distribution in a loaded osteon on two different exterior surface cases.Case I is stress free and fully permeable and case II is impermeable.The following are the results obtained.(i) The Haversian fluid may not be ignored because it can enlarge the whole osteonal fluid pressure field,and it bears the external loads together with the solid skeleton.(ii) The increase of both axial strain amplitude and frequency can result in the increase of fluid pressure and velocity amplitudes,while in case II,the frequency has little effect on the fluid pressure amplitude.(iii) Under the same loading conditions,the pressure amplitude in case II is larger than that in case I,while the velocity amplitude is smaller than that in case I.This model permits the linking of the external loads to the osteonal fluid pressure and velocity,which may be a stimulus to the mechanotransduction of bone remodeling signals. | WU XiaoGang CHEN WeiYi GAO ZhiPeng GUO HongMei WANG LiLi | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,9: | 7 |
| 11 | Structural optimization of uniaxial symmetry non-circular bolt clearance hole on turbine disk显示文摘This study proposes a parameterized model of a uniaxial symmetry non-circular hole, to improve conventional circular bolt clearance holes on turbine disks. The profile of the model consists of eight smoothly connected arcs, the radiuses of which are determined by 5 design variables.By changing the design variables, the profile of the non-circular hole can be transformed to accommodate different load ratios, thereby improving the stress concentration of the area near the hole and that of the turbine disk. The uniaxial symmetry non-circular hole is optimized based on finite element method(FEM), in which the maximum first principal stress is taken as the objective function. After optimization, the stress concentration is evidently relieved; the maximum first principal stress and the maximum von Mises stress on the critical area are reduced by 30.39% and 25.34%respectively, showing that the uniaxial symmetry non-circular hole is capable of reducing the stress level of bolt clearance holes on the turbine disk. | Chen Qiuren Guo Haiding Zhang Chao Liu Xiaogang | 2014 | Chinese Journal of Aeronautics2014,27,5: | 7 |

| 14 | Responses of the Zhe-Min coastal current adjacent to Pingtan Island to the wintertime monsoon relaxation in 2006 and its mechanism显示文摘In conjunction with synchronous remotely sensed winds and sea surface temperature(SST),the spatiotemporal features of the Zhe-Min coastal current(ZMCC),especially responses of the ZMCC adjacent to Pingtan Island(PT) to the wintertime monsoon relaxation in 2006 and corresponding mechanism are investigated based on the field observations.In situ data are acquired from Conductivity-Temperature-Depth(CTD) cruise and Bottom-Mounted Moorings(BMM),which are conducted during a comprehensive survey for the Chinese Offshore Investigation and Assessment Project in winter 2006.It is revealed that the ZMCC is well mixed vertically in winter 2006.The ZMCC(<14°C) recedes during the relaxation of the wintertime monsoon and is accompanied by the enhanced northward shift of the warm,saline Taiwan Strait Mixed Water(TSMW,higher than 14°C and is constituted by the Taiwan Strait Warm Water and the Kuroshio Branch Water).And greatly enhanced southward intrusion of the ZMCC can be detected when the wintertime monsoon restores.Correspondingly,the thermal interface bounded by the ZMCC and the TSMW moves in the northwest/southeast direction,leading to periodic warm/cold reversals of the near-seabed temperature adjacent to the PT.By EOF(Empirical Orthogonal Function) analysis of the large-scale wind fields and wavelet power spectrum analysis of the water level,ocean current and the near-seabed temperature,responses of the ZMCC off the PT to wintertime monsoon relaxation are suggested to be attributed mainly to the southward propagating coastally trapped waves triggered by the impeding atmospheric fronts.As a result,ocean current and near-seabed temperature demonstrate significant quasi-5 d and quasi-10 d subtidal oscillations.By contrast,the onshore/offshore water accumulation resulted from Ekman advection driven by the local winds has minor contributions. | PAN AiJun WAN XiaoFang GUO XiaoGang JING ChunSheng | 2013 | Science China Earth Sciences2013,56,3: | 5 |
| 15 | Wetting Behaviors and Interfacial Reaction between Sn-10Sb-5Cu High Temperature Lead-free Solder and Cu Substrate显示文摘Sn-10Sb-5Cu lead-free solder was fabricated for high temperature application in electronic package. Wetting behaviors and interfacial reaction between such a high temperature lead-free solder and Cu substrate were investigated and compared with those of 95Pb-Sn solder. The results showed that the wetting properties of Sn-10Sb-5Cu solder are superior to those of 95Pb-Sn solder in maximum wetting force, wetting time and wetting angle in the temperature range of 340-400 ℃. However, the surface of the Sn-10Sb-5Cu solder sample after wetting balance tests was rougher than that of 95Pb-Sn solder at the temperature lower than 360 ℃. In static liquid-state interfacial reaction, the types and thickness of the intermetallic compounds (IMCs) of both solders were different from each other. The wetting kinetics in the Sn-10Sb-5Cu/Cu system was more rapid than that in 95Pb-Sn/Cu system, and the higher formation rate of IMCs in the former system was considered as the reason. | Qiulian Zeng Jianjun Guo Xiaolong Gu Xinbing Zhao Xiaogang Liu | 2010 | Journal of Materials Science & Technology2010,26,2: | 5 |
| 16 | The spatio-temporal variation of wintertime subtidal currents in the western Taiwan Strait显示文摘A new data set of observations by six cruises of ship-mounted acoustic doppler current profiler(SADCP) and three 40 d long bottom-mounted ADCPs(BADCPs) is employed to reveal the spatiotemporal variability of tidal and subtidal currents in the western Taiwan Strait(TWS) during winter season. The results confirm the existence of intense cotidal lines for M_2 tidal current, which is located north of 25°N. In this case, no existence of an amphidromic point can be identified. It is also revealed that the counter-wind current(CWC) can extend through the whole western TWS and even occupy the entire water column during winter monsoon relaxation. However,this CWC is observed to be thoroughly overwhelmed by the downwind China coastal current(CCC) during the two big monsoon bloom events in the winter of 2007, and the CCC consequently extends southward throughout the western TWS instead. Most importantly, the variation of the spatial extent for the CWC and the CCC in the western TWS is found to be well explained by the first two modes of the vector empirical orthogonal function(VEOF) analysis, that is, it is mainly controlled by a wind-driven quasi barotropic current as the first mode and slightly modulated by a relatively weak background current with a first-order baroclinic structure as the second mode. | SHEN Junqiang QIU Yun GUO Xiaogang PAN Aijun ZHOU Xiwu | 2017 | Acta Oceanologica Sinica2017,36,11: | 5 |
| 17 | Responses of Guangdong coastal upwelling to the summertime typhoons of 2006显示文摘The effects of typhoon intrusion on the Guangdong coastal upwelling system were investigated on the basis of in situ CTD (conductivity-temperature-depth) cruise observations and especially upward-looking ADCP (Acoustic Doppler Current Profil- ers) measurements obtained from a comprehensive survey of the Guangdong coastal region carried out by the Chinese Off-shore Investigation and Assessment Project in the summer of 2006. It was found that northeastward geostrophic advection driven by the summer monsoon has a significant near-seabed onshore component adjacent to Shantou, which in conjunction with upper-level offshore Ekman flow, constitutes the canonical Guangdong coastal upwelling system. Further analyses suggested that the Guangdong coastal upwelling system is sensitive to subtle changes in the typhoon intensity and migration pathway. On one hand, as a typhoon approaches from north of the upwelling system (e.g. Typhoon 0604 (Bilis) and Typhoon 0605 (Kaemi)) in the early phase of intrusion, the enhanced southwesterly leads to exceptional enhancement of the onshore flow; i.e., enhanced upwelling. Afterward, irrespective of the forced ocean responses resulting from the stronger local winds (Typhoon 0604) or the moderate typhoon-induced inertial oscillations (Typhoon 0605), the situation is not conducive to sustaining a stable, persistent upwelling system. On the other hand, when there is typhoon intrusion south of the upwelling system (e.g. Typhoon 0606 (Prapiroon)), the favorable southwesterly tends to be substituted by an anomalous northeasterly, which destroys the traditional coastal upwelling pattern. However, the canonical upwelling system tends to recover within 1-2 days of the typhoon passing. | PAN AiJun GUO XiaoGang XU JinDian HUANG Jiang WAN XiaoFang | 2012 | Science China Earth Sciences2012,55,3: | 4 |
| 18 | Dislocation evolution with rheological forming of metal显示文摘It is known that some internal defects exist in metal materials. Preliminary attempt to relate dislocation evolution with metal rheological forming was done. By the attempt, it is learned that the evolution of dislocation density ρ(x, y, t) is essentially the change of n independent internal variables q α(α=1, 2, …, n) with material. The preliminary research in theory and experiments showed that dislocations piling up could be avoided. One can improve the internal microstructure and mechanical properties of products by rheological forming method. | Luo Yingshe(罗迎社) Guo Xiaogang(郭小刚) Mei Yafu(梅亚夫) Hu Yungui(胡云贵) | 1999 | 中国有色金属学会会刊:英文版1999,9,3: | 4 |
| 19 | Controlled mechanical assembly of complex 3D mesostructures and strain sensors by tensile buckling显示文摘Recent research establishes methods of controlled mechanical assembly as versatile routes to three-dimensional(3D)mesostructures from patterned 2D films,with demonstrated applicability to a broad range of materials(e.g.,semiconductors,polymers,metals,and their combinations)and length scales(e.g.,from sub-microscale to centimeter scale).Previously reported schemes use pre-stretched elastomeric substrates as assembly platforms to induce compressive buckling of 2D precursor structures,thereby enabling their controlled transformation into 3D architectures.Here,we introduce tensile buckling as a different,complementary strategy that bypasses the need for a pre-stretched platform,thereby simplifying the assembly process and opening routes to additional classes of 3D geometries unobtainable with compressive buckling.A few basic principles in mechanics serve as guidelines for the design of 2D precursor structures that achieve large out-of-plane motions and associated 3D transformations due to tensile buckling.Experimental and computational studies of nearly 20 examples demonstrate the utility of this approach in the assembly of complex 3D mesostructures with characteristic dimensions from micron to millimeter scales.The results also establish the use of nonlinear mechanics modeling as a mechanism for designing systems that yield desired 3D geometries.A strain sensor that offers visible readout and large detectable strain range through a collection of mechanically triggered electrical switches and LEDs serves as an application example. | Xiaogang Guo Xueju Wang Dapeng Ou Jilong Ye Wenbo Pang Yonggang Huang John A.Rogers Yihui Zhang | 2018 | npj Flexible Electronics2018,2,1: | 4 |
| 20 | The winter western boundary current of the South China Sea:physical structure and volume transport in December 1998显示文摘The unique survey in December 1998 mapped the entire western boundary area of the South China Sea(SCS),which reveals the three-dimensional structure and huge volume transport of the swift and narrow winter western boundary current of the SCS(SCSwwbc) in full scale. The current is found to flow all the way from the shelf edge off Hong Kong to the Sunda Shelf with a width around 100 km and a vertical scale of about 400 m. It appears to be the strongest off the Indo-China Peninsula, where its volume transport reached over 20×10~6 m^3/s. The current is weaker upstream in the northern SCS to the west of Hong Kong. A Kuroshio loop or detached eddy intruded through the Luzon Strait is observed farther east where the SCSwwbc no more exists. The results suggest that during the survey the SCSwwbc was fed primarily by the interior recirculation of the SCS rather than by the'branching' of the Kuroshio from the Luzon Strait as indicated by surface drifters, which is likely a near-surface phenomenon and only contributes a minor part to the total transport of the SCSwwbc. Several topics related to the SCSwwbc are also discussed. | LI Li GUO Xiaogang WU Risheng | 2018 | Acta Oceanologica Sinica2018,37,3: | 4 |
