| 1 | Progress and recent trend in MILD combustion显示文摘Moderate or intense low oxygen dilution(MILD)combustion plays a significant role in the mitigation of combustion-generated pollutants and greenhouse gases whilst meeting thermal efficiency needs.However,due to the lack of the fundamental knowledge on this combustion,there is a misconception that MILD combustion should be established by high preheating of the air,which has limited its application.Our research and development on this combustion has been performed for several years. We have found that the requirements for establishing the MILD combustion are more relaxed than previously.It is also revealed that this combustion of different type,i.e.,non-premixed,partially premixed and fully premixed,can be achieved by firing various fuels(i.e.,gaseous,liquid and solid fuels).It is suggested that the application of the MILD combustion can be expanded significantly.The present review summarizes the progress and recent trend made in the R&D of this combustion and recommends further fundamental studies for improving our knowledge and widening its applications. | LI PengFei MI JianChun DALLY B B WANG FeiFei WANG Lin LIU ZhaoHui CHEN Sheng ZHENG ChuGuang | 2011 | Science China(Technological Sciences)2011,54,2: | 31 |
| 2 | Ozone mini-hole occurring over the Tibetan Plateau in December 2003显示文摘By analyzing the total ozone data from TOMS and ground-based observations, it is found that a large area with extremely low ozone occurred over the Tibetan Plateau during December 14-17, 2003. After correcting the bias in TOMS data, the area with the total ozone < 220 DU is found to be over 2500000 km2, and the minimum value is only 190 DU. It is the first time that an ozone mini-hole or an extremely low ozone event is found to occur over the Tibetan Plateau. | BIAN Jianchun WANG Gengchen CHEN Hongbin QI Donglin LUE Daren ZHOU Xiuji | 2006 | Chinese Science Bulletin2006,51,7: | 19 |
| 3 | Preparation and Characterization of Three Monoclonal Antibodies against HIV-1 p24 Capsid Protein显示文摘HIV-1 p24 detection provides a means to aid the early diagnosis of HIV-1 infection, track the progression of disease and assess the efficacy of antiretroviral therapy. In the present study, three monoclonal antibodies (mAbs) p3JB9, p5F1 and p6F4 against HIV-1 p24 were generated. All mAbs could detect p24 of HIV-1IIIB, HIV-1Ada-M, HIV-174V mAbs p5F1 and p6F4 could detect HIV-1KM018, while p3JB9 could not. Three mAbs did not react with HIV-2ROD, HIV-2CBL-20 and SIVagmTYO-1. The recognized epitope of p5F1 was located on the Gag amino acid region DCKTILKALGPAATLEEMMTAC. The p5F1 was used to establish a modified sandwich ELISA with rabbit anti-p24 serum and showed good specificity and high sensitivity, which has been used to measure HIV-1 p24 antigen levels in research. | Guangjie Liu Jianping Wang Jianchun Xiao Zhiwei Zhao Yongtang Zheng | 2007 | Cellular & Molecular Immunology2007,4,3: | 14 |
| 4 | Statistics of gravity waves in the lower stratosphere over Beijing based on high vertical resolution radiosonde显示文摘The seasonal variation of inertia gravity-wave activity in the lower stratosphere (17―24 km) over Beijing is studied based on the high vertical resolution radionsonde observa- tions (from December 2001 to February 2003) of Beijing Observatory (116°28′E, 39°48′N). Some of the important gravity-wave parameters, such as intrinsic frequency, and propagation direction, are estimated according to the polarized relation among gravity-wave wind components and temperature. Time series of wave energy show that the largest wave amplitudes occur during the winter and the least during the summer, and the average of the KE:PE ratios is about 2.6. Zonal and meridional wind perturbations have almost the same roots of mean variances, which shows that the wave energy in the lower stratosphere is isotropic horizontally. The motion and tem- perature fields are dominated by waves with vertical wavelengths of 1.5―3 km, which occupy above 80% samples, with a mean value of about 2.3 km. The horizontal wavelengths are mainly distributed between 100―800 km, averaging 445 km. The ratio of the mean horizontal to vertical wavelength is about 200:1, which indicates that the wave propagates nearly horizontally, with a very small vertical angle. The intrinsic frequency is estimated by fitting a polarized ellipse to the wind perturbations after band-filtering waves with a wavelength of 1.5―3 km, and the results show that the intrinsic frequency is dominated by 1f―3.5f, with an averaging value of 2f, corre- sponding to an intrinsic time period of 9 hours. Wave energy is found to propagate mainly upward, and in the horizontal direction, there is clear azimuthal anisotropy, with predominate northwest propagation against the prevailing wind. | BIAN Jianchun CHEN Hongbin LU Daren | 2005 | Science China Earth Sciences2005,48,9: | 12 |
| 5 | Fractal characteristics of surface crack evolution in the process of gas-containing coal extrusion显示文摘In this paper, simulated experiment device of coal and gas outburst was employed to perform the experiment on gas-containing coal extrusion. In the experiment, coal surface cracks were observed with a high-speed camera and then the images were processed by sketch. Based on the above description, the paper studied the fractal dimension values from different positions of coal surface as well as their changing laws with time. The results show that there is a growing parabola trend of crack dimension value in the process of coal extrusion. Accordingly, we drew the conclusion that extruded coal crack evolution is a process of fractal dimension value increase. On the basis of fractal dimension values taken from different parts of coal masses, a fractal dimension of the contour map was drawn. Thus, it is clear that the contour map involves different crack fractal dimension values from different positions. To be specific, where there are complicated force and violent movement in coal mass, there are higher fractal dimension values, i.e., the further the middle of observation surface is from the exit of coal mass, and the lower the fractal dimension value is. In line with fractal geometry and energy theory of coal and gas outburst, this study presents the relation between fractal dimension and energy in the process of extruding. In conclusion, the evolution of crack fractal dimension value can signify that of energy, which has laid a solid foundation for the quantification research on the mechanism of gas-containing coal extrusion. | Chen Peng Wang Enyuan Ou Jianchun Li Zhonghui Wei Mingyao Li Xuelong | 2013 | International Journal of Mining Science and Technology2013,23,1: | 12 |
| 6 | Effect and Prospect of Basic Geological Survey Based on Airborne Gravimetry in China显示文摘The airborne gravimetry was an important leap and innovation in the world's history of geophysical exploration.China's first test of the airborne gravity geological survey in the onshore-offshore transitional area of the western and southern part of the Bohai Sea was successful and effective in geology.Based on the airborne gravity data,and combining previous ground gravity,seismic and drilling data etc.,we carried out the geological interpretation by forward and inverse methods.The result shows that the airborne Bouguer gravity anomaly was clear,the fracture interpretation was reliable,and the inversion depth of the main geological interfaces was relatively accurate.This airborne gravity geological survey not only filled the exploring gaps in the onshore-offshore transitional area,and realized the geological and tectonic junction between the sea and the land,but also discovered four local gravity anomalies,11 fractures and three sags or subsags,and so on.The good geological effect of airborne gravimetry not restricted by terrain condition shows that it can be served as a new geophysical method in the exploration of complex terrain physiognomy area such as mountain,jungle,desert,marsh,onshore-offshore transitional area and so on,and has an extensive application prospect in China in the future. | LI Wenyong ZHOU Jianxin XIONG Shengqing GUO Zhihong LU Wenfen XU Jianchun LIU Yanxu | 2012 | Acta Geologica Sinica(English Edition)2012,86,1: | 11 |
| 7 | Evidences of rapid erosion driven by climate in the Yarlung Zangbo (Tsangpo) Great Canyon,the eastern Himalayan syntaxis显示文摘Climate and tectonism are both particularly intense in the Yarlung Zangbo (Tsangpo) Great Canyon in the eastern Himalayan syntaxis,which is characterized by the most rapid landscape evolution of anywhere in the world.Thus,the eastern Himalayan syntaxis is one of the best locations to study the interactions between climate and tectonics.This paper investigates the cooling ages of the Doxong La-Baibung profile using apatite fission track (AFT) dating on 11 bedrock samples at elevations ranging from 4210 to 710 m.There are topographic,climatic,metamorphic,and thermochronological gradients in the profile,providing good conditions to study interactions between climate and tectonics.AFT ages ranged from 4.6±0.6 Ma to 1.7±0.3 Ma,and the mean fission track lengths ranged from 11.0 to 12.4 μm.It was found that the cooling rates revealed by AFT ages increased with decreasing elevation.However,the tendency of the cooling rates revealed by the 40 Ar-39 Ar ages was different from that indicated by the AFT ages.Moreover,for most districts of the eastern Himalayan syntaxis,the compiled AFT age distribution correlates well with the annual average precipitation,indicating the coupling of the cooling and erosion rates of the near-surface rock and precipitation.The geothermal history modeling results indicate an obvious increase in the cooling and erosion rate between 1.0 and 0.5 Ma.This age is consistent with other research findings for this time,when the vapor channel of the Yarlung Zangbo Great Canyon began to take effect.These evidences suggest that climate,especially precipitation,has acting as a key factor influencing the rapid cooling and erosion in the Yarlung Zangbo Great Canyon since 1-0.5 Ma. | YU XiangJiang JI JianQing GONG JunFeng SUN DongXia QING JianChun WANG LiNing ZHONG DaLai ZHANG ZhiCheng | 2011 | Chinese Science Bulletin2011,56,11: | 11 |
| 8 | A deep stratospheric intrusion associated with an intense cut-off low event over East Asia显示文摘European Centre for Medium-Range Weather Forecasts Re-Analysis Interim(ERA-Interim)reanalysis data and satellite data,and trajectory model were applied to analyze the dynamical,thermo-dynamical,and chemical structure in the upper troposphere and lower stratosphere(UTLS)of an intense cut-off low(COL)event occurring over East Asia during June 19-23,2010,and to characterize the process and transport pathway of deep stratospheric intrusion.The Atmospheric Infrared Sounder(AIRS)ozone data and the Global Positioning System Ozone(GPSO3)sonde data showed that the air mass originating from the polar formed a region with relatively high values of potential vorticity(PV)and ozone in the center of COL,and a secondary ozone peak appeared in the upper troposphere during mature stage of the COL.Forward trajectory simulation suggested that during the first stage of COL,deep stratospheric intrusion associated with strong northerly wind jet on the west side of the upper-level trough transported ozone-rich air from the polar lower stratosphere into the middle and lower troposphere in the mid-latitude,and increased the ozone concentration there.During the mature stage of the COL,stratospheric air was transported counterclockwise into the troposphere.Backward trajectory model was used to find the source regions of air mass within the COL during its mature stage.Model results show that air masses with high ozone concentration in the center of the COL have two source regions:one is the subpolar vortex which lies in northern part of Center Siberia,where ozone-rich air plays a major role in increasing the ozone concentrations,and the other is the strong shear region which is near by the cyclonic side of the extratropical jet axis(west of 90°E,near 50°N).The air masses with low ozone concentration around the COL also have two source regions:one is the anticyclonic side of the extratropical jet axis,where the air mass with the relatively low ozone concentration at the bottom of the COL is mainly controlled by horizontal movement,and the other is the warm area of the south side of COL,where the air mass on the east and west side of the COL is mainly dominated by upward motion. | LI Dan BIAN JianChun FAN QiuJun | 2015 | Science China Earth Sciences2015,58,1: | 10 |

| 10 | Cystathionine-γ-lyase ameliorates the histone demethylase JMJD3-mediated autoimmune response in rheumatoid arthritis显示文摘Cystathionine-γ-lyase(CSE),an enzyme associated with hydrogen sulfide(H2S)production,is an important endogenous regulator of inflammation.Jumonji domain-containing protein 3(JMJD3)is implicated in the immune response and inflammation.Here,we investigated the potential contribution of JMJD3 to endogenous CSE-mediated inflammation in rheumatoid arthritis(RA).Upregulated CSE and JMJD3 were identified in synovial fibroblasts(SFs)from RA patients as well as in the joints of arthritic mice.Knocking down CSE augmented inflammation in IL-1β-induced SFs by increasing JMJD3 expression.In addition,CSE−/−mice with collagen-induced arthritis(CIA)developed severe joint inflammation and bone erosion.Conversely,overexpressing CSE inhibited JMJD3 expression by the transcription factor Sp-1 and was accompanied by reduced inflammation in IL-1β-treated SFs.Furthermore,JMJD3 silencing or the administration of the JMJD3 inhibitor GSK-J4 significantly decreased the inflammatory response in IL-1β-treated SFs,mainly by controlling the methylation status of H3K27me3 at the promoter of its target genes.GSK-J4 markedly attenuated the severity of arthritis in CIA mice.In conclusion,suppressing JMJD3 expression by the transcription factor Sp-1 is likely responsible for the ability of CSE to negatively modulate the inflammatory response and reduce the progression of RA. | Weijun Wu Ming Qin Wanwan Jia Zheng Huang Zhongzheng Li Di Yang Mengwei Huang Chenxi Xiao Fen Long Jianchun Mao Philip K.Moore Xinhua Liu Yi Zhun Zhu | 2019 | Cellular & Molecular Immunology2019,16,8: | 9 |
| 11 | Application of coupled analysis methods for prediction of blast-induced dominant vibration frequency显示文摘Blast-induced dominant vibration frequency(DVF)involves a complex,nonlinear and small sample system considering rock properties,blasting parameters and topography.In this study,a combination of grey relational analysis and dimensional analysis procedures for prediction of dominant vibration frequency are presented.Six factors are selected from extensive effect factor sequences based on grey relational analysis,and then a novel blast-induced dominant vibration frequency prediction is obtained by dimensional analysis.In addition,the prediction is simplified by sensitivity analysis with 195 experimental blast records.Validation is carried out for the proposed formula based on the site test database of the firstperiod blasting excavation in the Guangdong Lufeng Nuclear Power Plant(GLNPP).The results show the proposed approach has a higher fitting degree and smaller mean error when compared with traditional predictions. | Li Haibo Li Xiaofeng Li Jianchun Xia Xiang Wang Xiaowei | 2016 | Earthquake Engineering and Engineering Vibration2016,15,1: | 8 |
| 12 | Observation of a Summer Tropopause Fold by Ozonesonde at Changchun,China:Comparison with Reanalysis and Model Simulation显示文摘Tropopause folds are one of the key mechanisms of stratosphere–troposphere exchange(STE) in extratropical regions,transporting ozone-rich stratospheric air into the middle and lower troposphere. Although there have been many studies of tropopause folds that have occurred over Europe and North America,a very limited amount of work has been carried out over northeastern Asia. Ozonesondes produced by the Institute of Atmospheric Physics were launched in Changchun(43.9?N,125.2?E),Northeast China,in June 2013,and observed an ozone-enriched layer with thickness of 3 km and an ozone peak of180 ppbv at 6 km in the troposphere. The circulation field from the European Centre for Medium-Range Weather Forecasts Interim Reanalysis(ERA-Interim) dataset shows that this ozone peak was caused by a tropopause fold associated with a jet stream at the eastern flank of the East Asian trough. By analyzing the ozone data from the ozone monitoring instrument and Weather Research and Forecasting model with Chemistry(WRF-Chem) simulations,it was found that a high ozone concentration tongue originating from the lower stratosphere at high latitude(near central Siberia) intruded into the middle troposphere over Changchun between 5 and 8 km on 12 June 2013. The high-resolution WRF-Chem simulation was capable of describing events such as the tropopause fold that occurred on the cyclonic shear side of the jet stream. In addition,the TRAJ3 D trajectory model was used to trace the origin of measured secondary ozone peaks in the middle troposphere back,for example,to stratospheric intrusion through the tropopause fold. | LI Dan BIAN Jianchun | 2015 | Advances in Atmospheric Sciences2015,32,10: | 8 |
| 13 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021,14,6: | 8 |
| 14 | PIV measurements of turbulent jets issuing from triangular and circular orifice plates显示文摘The present study experimentally investigated the near-field flow mixing characteristics of two turbulent jets issuing from equilateral triangular and circular orifice plates into effectively unbounded surroundings,respectively.Planar particle image velocimetry(PIV) was applied to measure the velocity field at the same Reynolds number of Re=50,000,where Re = UeDe /with Ue being the exit bulk velocity and the kinematic viscosity of fluid,D e the equivalent diameters.The instantaneous velocity,mean velocity,Reynolds stresses were obtained.From the mean velocity field,the centreline velocity decay rate and half-velocity width were derived.Comparing the mixing characteristics of the two jets,it is found that the triangular jet has a faster mixing rate than the circular counterpart.The triangular jet entrainments with the ambient fluid at a higher rate in the near field.This is evidenced by a shorter unmixed core,faster Reynolds stress and centreline turbulence intensity growth.The primary coherent structures in the near field are found to break down more rapidly in the triangular jet as compared to the circular jet.Over the entire measurement region,the triangular jet maintained a higher rate of decay and spread.Moreover,all components of Reynolds stress of the triangular jet appear to reach their peaks earlier,and then decay more rapidly than those of the circular jet.In addition,the axis-switching phenomenon is observed in the triangular jet. | XU MinYi ZHANG JianPeng MI JianChun NATHAN G J KALT P A M | 2013 | Science China(Physics,Mechanics & Astronomy)2013,56,6: | 7 |
| 15 | Morphologies of Al_4Sr Intermetallic Phase and Its Modification Property upon A356 Alloys显示文摘In general,the modification performance of Al-Sr master alloys is primarily dependent upon the morphologies and sizes of the Al_4Sr intermetallic phase.In this paper,the crystal structure,morphologies,sizes,hardness and elastic modulus of Al_4Sr in Al-Sr master alloys prepared from variant processes were studied by means of optical metallurgical microscope,X-ray diffraction(XRD),scanning electron microscopy(SEM),and nanoindentation system.The results revealed that the microstructures and modification performance of the Al_4Sr phase were related to the preparation processes.That is to say,when a 'direct reaction-hot extrusion' process was used,the Al_4Sr phase exhibited a homogeneous distribution in the Al matrix with small size and roundish shapes,which ensured the Al-Sr master alloy wire advantages involving high recovery,good reproducibility,no delitescence of modification,no corrosion on equipments,and good workability.However,in the case of the traditional 'direct reaction' process,the Al4Sr phase was in large size with shapes of rectangular stripe and plates,which limited the Sr content increasing due to the brittleness of the Al-Sr alloy.It was also found that the morphology and size of the Al_4Sr phases changed during heat treatment at high temperature up to 600 ℃. | Chengwei Liao Jianchun Chun Yang Li Rui Tu Chunxu Pan | 2012 | Journal of Materials Science & Technology2012,28,6: | 7 |
| 16 | Effect of Sophora flavescens alkaloid on aerobic vaginitis in gel form for local treatment显示文摘OBJECTIVE: To investigate the effect of Sophora flavescens alkaloid(SFA) in gel form on aerobic vaginitis(AV) and the possible mechanism underlying the effects.METHODS: AV rat models were prepared by intravaginal inoculation of Escherichia coli and Staphylococcus aureus. SFA gel and placebo gel were intravaginally administered. In vivo antibacterial effects,vaginal microenvironment, vaginal smears, pathological tissues of vaginas, and retention of gel in the vaginal cavity were investigated.RESULTS: SFA gel had much higher antibacterial effect than placebo gel. SFA gel protected the vaginal mucosa from erosion of bacteria. At the same time,they inhibited the inflammatory responses, exhibiting little leukocytes and parabasal cells. Furthermore, the number of vaginal Lactobacilli remarkably increased following administration of SFA gel.However, the vaginal p H did not recover to thehealthy acidic levels after treatment due to the buffering effect of gel. The gel of a fluorescent agent,Cyanine 7, showed very long retention time in the vaginal cavity, up to more than 24 h, much longer than the solutions.CONCLUSION: The SFA gel is a promising medicine for local treatment of AV with the advantages of anti-bacteria, protection of vaginal mucosa, increase of Lactobacilli, and long retention time in the vaginal cavity. | Wang Xiu Li Jianchun Hu Yuzhen Chen Wenyang Jin Yiguang | 2017 | Journal of Traditional Chinese Medicine2017,37,3: | 7 |
| 17 | Study of Residual Basin and Tectonolayering Based on Airborne Gravity and Magnetic Data显示文摘This paper takes the South Yellow Sea as an example to show a new method for comprehensive geological-geophysical research such as residual basin and tectonolayering using airborne gravity and magnetic data in China. Based on airborne gravity and magnetic data, by measuring and analyzing stratigraphic density and susceptibility, the depths to the pre-Sinian magnetic basement top, the pre-Jurassic top and the Cenozoic bottom, are obtained by forward and inverse methods constrained by seismic and drilling data; and furthermore, the residual thicknesses of the Sinian-Triassic, the Jurassic-Cretaceous and the Cenozoic are calculated. Based on airborne gravity and magnetic anomalies, the faults in the pre-Sinian magnetic basement, the Jurassic-Cretaceous and the Cenozoic are respectively interpreted by the qualitative and quantitative methods. On the basis of the above study, and combining regional important tectonic events, four tectonolayers are divided in the vertical succession in South Yellow Sea, namely the pre-Sinian magnetic basement, the Sinian-Triassic, the Jurassic-Cretaceous and the Cenozoic. The result shows that there are thick Cenozoic and Jurassic-Cretaceous strata and thin residual Sinian-Triassic strata in the Suzhong-Huangnan depression area, but there are thin or only sporadic Mesozoic-Cenozoic terrestrial strata and thick Sinian-Triassic marine strata reserved in Subei-Huangzhong uplift area and Sunan-Wunansha uplift area. The four tectonolayers are very different in structures as well as distributions in plane. | LI Wenyong ZHOU Jianxin XIONG Shengqing LIU Yanxu XU Jianchun | 2013 | Acta Geologica Sinica(English Edition)2013,87,4: | 6 |
| 18 | Modification performance on 4032 Al alloy by using Al–10Sr master alloys manufactured from different processes显示文摘The microstructures and modification performance on 4032 aluminum alloy of the Al–10Sr master alloy wire prepared from 'direct reaction-hot extrusion' and the trapezoidal block from 'direct reaction' were systemically studied by using optical metallurgical microscope, XRD and SEM. It was found that the preparation processes exhibited a significant effect on the microstructures of the Al–10Sr, which thereby influenced its modification performance. It has been found that when the Al–10Sr alloy wire was used, a desirable modification was obtained after 2 min and reached to the best performance at 60 min, and the optimum Sr addition amount was 0.04–0.06 wt%, and the good modification performance was kept even after 300 min. However, when the Al–10Sr alloy trapezoidal block was used, a desirable modification was started after 30 min and reached to the best performance as long as 120 min, and the optimum Sr addition amount was 0.06–0.08 wt%, and the effective modification period was only180 min. Therefore, comparing with the Al–10Sr alloy trapezoidal block, the Al–10Sr alloy wire had better modification efficiency, which not only reduced the Sr addition amount of about 30%, but also greatly decreased the incubation time and improved the ability of anti-fading. | Chengwei Liao Jianchun Chen Yunlong Li Huan Chen Chunxu Pan | 2014 | Progress in Natural Science:Materials International2014,24,2: | 6 |
| 19 | Recent progress in dengue vaccine development显示文摘Dengue virus(DENV) has four distinct serotypes. DENV infection can result in classic dengue fever and life-threatening dengue hemorrhagic fever/dengue shock syndrome. In recent decades, DENV infection has become an important public health concern in epidemic-prone areas. Vaccination is the most effective measure to prevent and control viral infections. However, several challenges impede the development of effective DENV vaccines, such as the lack of suitable animal models and the antibody-dependent enhancement phenomenon. Although no licensed DENV vaccine is available, significant progress has been made. This review summarizes candidate DENV vaccines from recent investigations. | Jianchun Wei Hui Chen Jing An | 2014 | Virologica Sinica2014,29,6: | 6 |
