| 2 | Seismic damage of highway bridges during the 2008 Wenchuan earthquake显示文摘Many highway bridges were severely damaged or completely collapsed during the 2008 Wenchuan earthquake.A fi eld investigation was carried out in the strongly affected areas and over 320 bridges were examined.Damage to some representative highway bridges is briefly described and a preliminary analysis of the probable causes of the damage is presented in this paper.The most common damage included shear-flexural failure of the pier columns,expansion joint failure,shear key failure,and girder sliding in the transversal or longitudinal directions due to weak connections between girder and bearings.Lessons learned from this earthquake are described and recommendations related to the design of curved and skewed bridges,design of bearings and devices to prevent girder collapse,and ductility of bridge piers are presented.Suggestions for future seismic design and retrofi tting techniques for bridges in moderate to severe earthquake areas are also proposed. | Han Qiang Du Xiuli Liu Jingbo Li Zhongxian Li Liyun Zhao Jianfeng | 2009 | Earthquake Engineering and Engineering Vibration2009，8，2： | 60 |

| 4 | Failure behavior of a rock-coal-rock combined body with a weak coal interlayer显示文摘Using an MTS 815 testing machine,the deformation and failure behavior of a rock-coal-rock combined body containing a weak coal interlayer has been investigated and described in this paper.Uniaxial loading leads to the appearance of mixed cracks in the coal body which induce instability and lead to bursts in coal.If the mixed crack propagates at a sufficiently high speed to carry enough energy to damage the roof rock,then coal and rock bursts may occur-this is the main mechanism whereby coal bumps or coal and rock bursts occur after excavation unloading.With increasing confining pressure,the failure strength of a rock-coal-rock combined body gradually increases,and the failure mechanism of the coal interlayer also changes,from mixed crack damage under low confining pressures,to parallel crack damage under medium confining pressures,and finally to single shear crack damage or integral mixed section damage under high confining pressures.In general,it is shown that a weak coal interlayer changes the form of overall coal damage in a rock-coal-rock combined body and reduces the overall stability of a coal body.Therefore,the whole failure behavior of a rock-coal-rock combined body in large cutting height working faces is controlled by these mechanisms. | Zuo Jianping Wang Zhaofeng Zhou Hongwei Pei Jianliang Liu Jianfeng | 2013 | International Journal of Mining Science and Technology2013，23，6： | 32 |
| 5 | Long-term follow-up of the effects of fecal microbiota transplantation in combination with soluble dietary fiber as a therapeutic regimen in slow transit constipation显示文摘As some studies have reported that strategies targeting the gut microbiota such as fecal microbiota transplantation(FMT) with or without other microecological therapy might have efficacy in treating slow transit constipation(STC), we conducted a singlecenter, open-label trial to study the long-term effect of FMT combined with soluble dietary fiber(pectin) on STC. Thirty-one adult patients with STC were enrolled into the trial. Patients received 6-day FMT procedures repeatedly for the first 3 months and soluble dietary fiber(pectin) daily during the follow-up. The rate of clinical remission and improvement, stool consistency, the Wexner constipation scale, and assessment of constipation-related symptoms were evaluated at week 4 and 1 year later. The clinical remission and improvement rates at week 4 were 69.0%(20/29) and 75.9%(22/29), respectively. At the end of the study,48.3%(14/29) of patients continued to have at least three complete spontaneous bowel movements per week and 58.6%(17/29)of patients showed clinical improvements. Stool consistency, the Wexner constipation scale, and constipation symptoms improved both at short-term and long-term follow-up. The results indicated that FMT in combination with soluble dietary fiber(pectin) had both short-term and long-term efficacy in treating STC. | Xueying Zhang Hongliang Tian Lili Gu Yongzhan Nie Chao Ding Xiaolong Ge Bo Yang Jianfeng Gong Ning Li | 2018 | Science China(Life Sciences)2018，61，7： | 33 |

| 7 | Geochronology, geochemistry, and its geological significance of the Permian Mandula mafic rocks in Damaoqi, Inner Mongolia显示文摘The Hujierte-Chaganhadamiao volcanic-plutonic sequence is located in the Mandula area of northern Damaoqi, Inner Mongolia. It contains mainly mafic volcanics, with several ultramafic blocks in its central part and mafic-intermediate intrusions in the east. The zircon U-Pb ages of the gabbro and basalt samples are 278.5±3.0 Ma (MSWD=0.66) and 273.7±1.0 Ma (MSWD=0.36), respectively. These ages constrain the magmatism occurred in the Early Permian. The Mandula Permian mafic rocks are characterized by low abundances of REE and slightly LREE-enriched chondrite-normalized N-MORB-type REE patterns. And these mafic samples have high ( 143 Nd/ 144 Nd) i (0.51262-0.51270), relatively high positive ε Nd (t) (3.4-8.0), and high Mg # (49-54), suggesting derivation from the depleted asthenosphere mantle source. But they also show the enrichment in large ion lithophile elements (LILE, e.g. Rb, Ba and Sr), depletion in high field strength elements (HFSE); distinctly negative Nb, Ta anomalies and slightly negative P, Ti anomalies; high ( 87 Sr/ 86 Sr) i (0.70490-0.70537), low ( 206 Pb/ 204 Pb) i (17.39-17.93). All of these resemble the characteristics of the enriched mantle source or involvement of arc materials in the magma genesis. Furthermore, as shown in the correlation plots of ε Nd (t) vs ( 87 Sr/ 86 Sr) i , ( 206 Pb/ 204 Pb) i vs ( 207 Pb/ 204 Pb) i and ( 208 Pb/ 204 Pb) i , La/Ba La/Nb vs La/Nb, and La/Nb ratio, the magma source could have been experienced the contamination and metasomation from the previous subduction process. And the positive correlation between the selected major oxides and trace elements could be explained by the contamination from continental crust and arc materials during the magmatic emplacement. Combined with the distinct geochemistry features of Mandula mafic samples and many previous researches in the study area, the Early Permian magmatism in Mandula occurred under an extensional rift setting, and a juvenile ocean basin probably had already been formed after further development. | CHEN Chen ZHANG ZhiCheng GUO ZhaoJie LI JianFeng FENG ZhiShuo TANG WenHao | 2012 | Science China Earth Sciences2012，55，1： | 30 |
| 8 | Orbit determination for Chang'E-2 lunar probe and evaluation of lunar gravity models显示文摘The Unified S-Band(USB) ranging/Doppler system and the Very Long Baseline Interferometry(VLBI) system as the ground tracking system jointly supported the lunar orbit capture of both Chang'E-2(CE-2) and Chang'E-1(CE-1) missions.The tracking system is also responsible for providing precise orbits for scientific data processing.New VLBI equipment and data processing strategies have been proposed based on CE-1 experiences and implemented for CE-2.In this work the role VLBI tracking data played was reassessed through precision orbit determination(POD) experiments for CE-2.Significant improvement in terms of both VLBI delay and delay rate data accuracy was achieved with the noise level of X-band band-width synthesis delay data reaching 0.2-0.3 ns.Short-arc orbit determination experiments showed that the combination of only 15 min's range and VLBI data was able to improve the accuracy of 3 h's orbit using range data only by a 1-1.5 order of magnitude,confirming a similar conclusion for CE-1.Moreover,because of the accuracy improvement,VLBI data was able to contribute to CE-2's long-arc POD especially in the along-track and orbital normal directions.Orbital accuracy was assessed through the orbital overlapping analysis(2 h arc overlapping for 18 h POD arc).Compared with about 100 m position error of CE-1's 200 km 200 km lunar orbit,for CE-2's 100 km 100 km lunar orbit,the position errors were better than 31 and 6 m in the radial direction,and for CE-2's 15 km 100 km orbit,the position errors were better than 45 and 12 m in the radial direction.In addition,in trying to analyze the Delta Differential One-Way Ranging(DOR) experiments data we concluded that the accuracy of DOR delay was dramatically improved with the noise level better than 0.1 ns and systematic errors better calibrated,and the Short-arc POD tests with DOR data showed excellent results.Although unable to support the development of an independent lunar gravity model,the tracking data of CE-2 provided evaluations of different lunar gravity models through POD.It is found that for the 100 km 100 km lunar orbit,with a degree and order expansion up to 165,JPL's gravity model LP165P did not show noticeable improvement over Japan's SGM series models(100×100),but for the 15 km×100 km lunar orbit,a higher degree-order model can significantly improve the orbit accuracy. | Li PeiJia Hu XiaoGong Huang Yong Wang GuangLi Jiang DongRong Zhang XiuZhong Cao JianFeng Xin Nan | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，3： | 30 |
| 9 | Predicting lifetime risk for developing atherosclerotic cardiovascular disease in Chinese population:the China-PAR project显示文摘Evidence on the lifetime risk for atherosclerotic cardiovascular disease(ASCVD) is insufficient;yet,estimating an individual's lifetime risk allows for a comprehensive assessment of ASCVD burden.We developed and validated lifetime risk prediction equations for ASCVD using four large and ongoing prospective cohorts of Chinese,the China-PAR project(Prediction for ASCVD Risk in China).Sexspecific equations were developed using two cohorts(as the derivation cohort) of 21,320 participants.Two other independent cohorts with 14,123 and 70,838 participants were used for their external validation,respectively.We evaluated both calibration and discrimination measures for model performance.Furthermore,we estimated ASCVD-free years lost or excess absolute risk attributable to high 10-year risk(!10.0%) and/or high lifetime risk(!32.8%).After 12.3 years' follow-up of the derivation cohort,1048 ASCVD events and 1304 non-ASCVD deaths were identified.Our sex-specific equations had good internal validation,with discriminant C statistics of 0.776(95% confidence interval [CI]:0.757–0.794) and 0.801(95% CI:0.778–0.825),and calibration χ~2 of 9.2(P = 0.418) and 5.6(P = 0.777) for men and women,respectively.Good external validation was also demonstrated with predicted rates closely matched to the observed ones.Compared with men having both low 10-year and low lifetime risk,men would develop ASCVD 3.0,4.6 and 8.6 years earlier if they had high 10-year risk alone,high lifetime risk alone,or both high 10-year and high lifetime risk at the index age of 35 years,respectively.We developed wellperformed lifetime risk prediction equations that will help to identify those with the greatest potential to avert ASCVD burden after implementation of innovative clinical and public health interventions in China. | Fangchao Liu Jianxin Li Jichun Chen Dongsheng Hu Ying Li Jianfeng Huang Xiaoqing Liu Xueli Yang Jie Cao Chong Shen Ling Yu Zhendong Liu Xianping Wu Liancheng Zhao Xigui Wu Dongfeng Gu Xiangfeng Lu | 2018 | Science Bulletin2018，63，12： | 30 |
| 10 | Facile Synthesis and Application of Ag-Chemically Converted Graphene Nanocomposite显示文摘An in situ chemical synthesis approach has been employed to prepare an Ag-chemically converted graphene (CCG) nanocomposite. The reduction of graphene oxide sheets was accompanied by generation of Ag nanoparticles. The structure and composition of the nanocomposites were confirmed by means of transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray diffraction. TEM and AFM results suggest a homogeneous distribution of Ag nanoparticles (5-10 nm in size) on CCG sheets. The intensities of the Raman signals of CCG in such nanocomposites are greatly increased by the attached silver nanoparticles, i.e., there is surface-enhanced Raman scattering activity. In addition, it was found that the antibacterial activity of free Ag nanoparticles is retained in the nanocomposites, which suggests they can be used as graphene-based biomaterials. | Jianfeng Shen Min Shi Na Li Bo Yan Hongwei Ma Yizhe Hu Mingxin Ye | 2010 | Nano Research2010，3，5： | 29 |
| 11 | Nondestructive Testing and Characterization of Residual Stress Field Using an Ultrasonic Method显示文摘To address the difficulty in testing and calibrating the stress gradient in the depth direction of mechanical components, a new technology of nondestructive testing and characterization of the residual stress gradient field by ultrasonic method is proposed based on acoustoelasticity theory. By carrying out theoretical analysis, the sensitivity coefficients of different types of ultrasonic are obtained by taking the low carbon steel(12%C) as a research object. By fixing the interval distance between sending and receiving transducers, the mathematical expressions of the change of stress and the variation of time are established. To design one sending-one receiving and oblique incidence ultrasonic detection probes, according to Snell law, the critically refracted longitudinal wave(LCR wave) is excited at a certain depth of the fixed distance of the tested components. Then, the relationship between the depth of LCR wave detection and the center frequency of the probe in Q235 steel is obtained through experimental study. To detect the stress gradient in the depth direction, a stress gradient LCR wave detection model is established, through which the stress gradient formula is derived by the relationship between center frequency and detecting depth. A C-shaped stress specimen of Q235 steel is designed to conduct stress loading tests, and the stress is measured with the five group probes at different center frequencies. The accuracy of ultrasonic testing is verified by X-ray stress analyzer. The stress value of each specific depth is calculated using the stress gradient formula. Accordingly, the ultrasonic characterization of residual stress field is realized. Characterization results show that the stress gradient distribution is consistent with the simulation in ANSYS. The new technology can be widely applied in the detection of the residual stress gradient field caused by mechanical processing, such as welding and shot peening. | SONG Wentao XU Chunguang PAN Qinxue SONG Jianfeng | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 27 |
| 12 | Identification of a Stable Quantitative Trait Locus for Percentage Grains with White Chalkiness in Rice (Oryza sativa)显示文摘High chalkiness is a major problem in many rice-producing areas of the world, especially in hybrid rice (Oryza sativa L.) in China. We previously showed a major quantitative trait locus for the percentage of grains with white chalkiness (QTLqPGWC-8) in the interval G1149-R727 on chromosome 8 using a chromosome segment substitution line (CSSL). Here, we selected the line-CSSL50 harboring the QTLqPGWC-8 allele from the CSSLs derived from a cross between Asominori (as a recurrent parent) and IR24 (as a donor parent), which had higher percentage chalkiness, markedly different from that of Asominori. There were also significant differences in starch granules, appearance of amylose content (AAC) and milling qualities between Asominori and CSSL50, but not in grain size or thousand grain weight (TGW). The BC4F2 and BC4F3 populations from a cross between CSSL50 and Asominori were used for fine mapping of qPGWC-8. We narrowed down the location of this QTL to a 142 kb region between Indel markers 8G-7 and 8G-9. QTLqPGWC-8 accounted for 50.9% of the difference in PGWC between the parents. The markers tightly linked to qPGWC-8 should facilitate cloning of the gene underlying this QTL and will be of value for marker-assisted selection in breeding rice varieties with better grain quality. | Tao Guo Xiaolu Liu Xiangyuan Wan Jianfeng Weng Shijia Liu Xi Liu Mingjiang Chen Jingjing Li Ning Su Fuqing Wu Zhijun Cheng Xiuping Guo Cailin Lei Jiulin Wang Ling jiang Jianmin Wan | 2011 | Journal of Integrative Plant Biology2011，53，8： | 25 |
| 13 | Effect of myosin heavy chain composition of muscles on meat quality in Laiwu pigs and Duroc显示文摘In order to explain the mechanism of high meat quality in Laiwu pigs and investigate the relation between myosin heavy chains (MyHC) composition and meat quality, meat quality analysis was conducted and mRNA expression of MyHC I, IIa, IIx, IIb was quantified by real-time fluorescence PCR in longissimus muscle (LM) and semimembranous muscle of Laiwu pigs and Duroc. The result indicated that, compared with Duroc, mRNA expression of MyHC IIa, IIx in LM and semimembranous muscle of Laiwu pigs was significantly increased, mRNA expression of MyHC IIb was dramatically decreased. However, the expression of MyHC I was not significantly affected by breeds. The correlation between mRNA expression of MyHC I, IIa, IIx in LM and meat color, pH value, marbling, intramuscular fat content was positive, but shear value of LM was negative. The relation between MyHC IIb mRNA expression and marbling, intramuscular fat content was dramatically negative, whereas shear value was strikingly positive, as well as fiber diameter, but without reaching statistical significance. Therefore, the composition of MyHC I, IIa, IIx, IIb affected meat quality, furthermore, expression of MyHC I, IIa, IIx, IIb mRNA prominently influenced meat characteristics, especially edible quality of muscle, suggesting that mRNA expression level of MyHC I, IIa, IIx, IIb can exactly and impersonally estimate meat quality. | HU HongMei, WANG JiYing, ZHU RongSheng, GUO JianFeng & WU Ying Institute of Animal Science and Veterinary Medicine, Shandong Academy of Agricultural Sciences, Jinan 250100, China | 2008 | Science China(Life Sciences)2008，51，2： | 26 |
| 14 | Acyclic edge colorings of planar graphs and series-parallel graphs显示文摘A proper edge coloring of a graph G is called acyclic if there is no 2-colored cycle in G. The acyclic edge chromatic number of G, denoted by a (G), is the least number of colors in an acyclic edge coloring of G. Alon et al. conjectured that a (G) Δ(G) + 2 for any graphs. For planar graphs G with girth g(G), we prove that a (G) max{2Δ(G) + 2, Δ(G) + 22} if g(G) 3, a (G) Δ(G) + 2 if g(G) 5, a (G) Δ(G) + 1 if g(G) 7, and a (G) = Δ(G) if g(G) 16 and Δ(G) 3. For series-parallel graphs G, we have a (G) Δ(G) + 1. | HOU JianFeng WU JianLiang LIU GuiZhen LIU Bin | 2009 | Science China Mathematics2009，52，3： | 24 |
| 15 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008，28，5： | 24 |

| 19 | The porosity origin of dolostone reservoirs in the Tarim, Sichuan and Ordos basins and its implication to reservoir prediction显示文摘Origin of dolostone remained a controversial subject, although numerous dolomitization models had been proposed to date. Because of the dolomitization's potential to be hydrocarbon reservoirs, one debatable issue was the role of dolomitization in porosity construction or destruction. Based upon case studies of dolostone reservoirs in various geological settings such as evaporative tidal flat(Ordos Basin, NW China), evaporative platform(Sichuan Basin, SW China), and burial and hydrothermal diagenesis(Tarim Basin, NW China), here we systematically discuss the origin of porosity in dolostone reservoirs. Contrary to traditional concepts, which regarded dolomitization as a significant mechanism for porosity creation, we found two dominant factors controlling reservoir development in dolostones, i.e., porosity inherited from precursor carbonates and porosity resulted from post-dolomitization dissolution. Actually, dolomitization rarely had a notable effect on porosity creation but rather in many cases destroyed pre-existing porosity such as saddle dolostone precipitation in vugs and fractures. Porosity in dolostones associated with evaporative tidal flat or evaporative platform was generally created by subaerial dissolution of evaporites and/or undolomitized components. Porosity in burial dolostones was inherited mostly from precursor carbonates, which could be enlarged due to subsequent dissolution. Intercrystalline porosity in hydrothermal dolostones was either formed during dolomitization or inherited from precursor carbonates, whereas dissolution-enlarged intercrystalline pores and/or vugs were usually interpreted to be the result of hydrothermal alteration. These understandings on dolostone porosity shed light on reservoir prediction. Dolostone reservoirs associated with evaporative tidal flat were laterally distributed as banded or quasi-stratified shapes in evaporite-bearing dolostones, and vertically presented as multi-interval patterns on tops of shallowing-upward cycles. Dolostone reservoirs associated with evaporative platform commonly occurred along epiplatforms or beneath evaporite beds, and vertically presented as multi-interval patterns in dolostones and/or evaporite-bearing dolostones of reef/shoal facies. Constrained by primary sedimentary facies, burial dolostone reservoirs were distributed in dolomitized, porous sediments of reef/shoal facies, and occurred vertically as multi-interval patterns in crystalline dolostones on tops of shallowing-upward cycles. Hydrothermal dolomitization was obviously controlled by conduits(e.g., faults, unconformities), along which lenticular reservoirs could develop. | ZHAO WenZhi SHEN AnJiang ZHENG JianFeng QIAO ZhanFeng WANG XiaoFang LU JunMing | 2014 | Science China Earth Sciences2014，57，10： | 23 |
| 20 | Comparison of Chlorophyll and Photosynthesis Parameters of Floating and Attached Ulva prolifera显示文摘In mid-May 2008 a serious green tide caused mainly by floating Ulva prolifera(Mller) J.Agardh(Chlorophyta,Ulvales) thalli struck the coastal area of Qingdao,China.To understand the present physiological conditions of the floating alga,in this work both laboratory and field investigations were conducted on the floating U.prolifera thalli in comparison with the attached U.prolifera thalli collected from the area.The floating thalli of three distinctively different colors and attached thalli at three different stages of sporangium formation process were characterized under a microscope,while their photosynthetic parameters were determined with chlorophyll fluorescence technology.On the other hand,the sporangium formation status of the floating U.prolifera thalli was surveyed both in the laboratory and in the field.Comparisons showed that both of the paired morphological characteristics and the paired physiological parameters of the floating and attached U.prolifera thalli were consistent.Furthermore,some spores were confirmed in the field and some motile particles were found within the floating thalli.These results suggest that the floating U.prolifera thalli with different colors could be at different stages of sporangium formation.However,our results also showed that the floating alga thalli have only a limited reproductive potential.This might limit the duration and the further geographic expansion of the green algal bloom. | Apeng Lin Songdong Shen Guangce Wang Qianqian Yi Hongjin Qiao Jianfeng Niu Guanghua Pan | 2011 | Journal of Integrative Plant Biology2011，53，1： | 20 |
