| 1 | Effect of N and P addition on soil organic C potential mineralization in forest soils in South China显示文摘Atmospheric nitrogen deposition is at a high level in some forests of South China. The effects of addition of exogenous N and P on soil organic carbon mineralization were studied to address: (1) if the atmospheric N deposition promotes soil C storage through decreasing mineralization; (2) if the soil available P is a limitation to organic carbon mineralization. Soils (0-10 cm) was sampled from monsoon evergreen broad-leaved forest (MEBF), coniferous and broad-leaved mixed forest (CBMF), and Pinus massoniana forest (PMF) in Dinghushan Biosphere Reserve (located in Guangdong Province, China). The soils were incubated at 25°C for 45 weeks, with addition of N (NH4NO3 solution) or P (KH2PO4 solution). CO2-C emission and the inorganic N (NH4+-N and NO3?-N) of the soils were determined during the incubation. The results showed that CO2-C emission decreased with the N addition. The addition of P led to a short-term sharp increase in CO2 emission after P application, and the responses of CO2-C evolution to P addition in the later period of incubation related to forest types. Strong P inhibition to CO2 emission occurred in both PMF and CBMF soils in the later incubation. The two-pool kinetic model was fitted well to the data for C turnover in this experiment. The model analysis demonstrated that the addition of N and P changed the distribution of soil organic C between the labile and recalcitrant pool, as well as their mineralization rates. In our experiment, soil pH can not completely explain the negative effect of N addition on CO2-C emission. The changes of soil inorganic N during incubation seemed to support the hypothesis that the polymerization of added nitrogen with soil organic compound by abiotic reactions during incubation made the added nitrogen retard the soil organic carbon mineralization. We conclude that atmospheric N deposition contributes to soil C accretion in the three subtropical forest ecosystems, however, the shortage of soil available P in CBMF and PMF may also retard soil organic C mineralization. | OUYANG, Xuejun ZHOU, Guoyi HUANG, Zhongliang ZHOU, Cunyu LI, Jiong SHI, Junhui ZHANG, Deqiang | 2008 | Journal of Environmental Sciences2008，20，9： | 17 |

| 3 | Preparation of one-dimensional nanostructured ZnO显示文摘Rod-like ZnO particles were synthesized via a sol-gel method by adding ethylene diamine(EDA) to the reaction system of Zn(Ac)2·2H2O and H2C2O4·2H2O.The crystal phase and morphology of the products were characterized by XRD(X-ray powder diffractometer) and TEM(transmission electron microscope).Rod-like ZnO belongs to the hexagonal Wurtzite system,with diameters and lengths of about 20-200 nm and 0.2-1.5 m,respectively.Experimental results showed that the morphology of nano-ZnO can be controlled by modulating the quantities of EDA added into the reaction system and that EDA plays an important role in the formation of rod-like ZnO particles.The growth mechanism of the rod-like nanoZnO was briefly discussed.The proposed facile,reproducible,effective and low-cost synthesis promises future large-scale preparation of nanostructured ZnO for application in nanotechnology. | Xiuping Jiang Youzhi Liu Yanyang Gao Xuejun Zhang Lihong Shi | 2010 | Particuology2010，8，4： | 4 |
| 4 | Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence. | Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu | 2019 | Biosafety and Health2019，1，3： | 3 |
| 5 | Bottom Currents Observed in and Around a Submarine Valley on the Continental Slope of the Northern South China Sea显示文摘Bottom currents at about 1000 m depth in and around a submarine valley on the continental slope of the northern South China Sea were studied by a 14-month long experiment from July 2013 to September 2014. The observations reveal that bottom currents are strongly influenced by the topography, being along valley axis or isobaths. Power density spectrum analysis shows that all the currents have significant peaks at diurnal and semi-diurnal frequencies. Diurnal energy is dominant at the open slope site, which is consistent with many previous studies. However, at the site inside the valley the semi-diurnal energy dominates, although the distance between the two sites of observation is quite small(11 km) compared to a typical horizontal first-mode internal tide wavelength(200 km). We found this phenomenon is caused by the focusing of internal waves of certain frequencies in the valley. The inertial peak is found only at the open slope site in the first deployment but missing at the inside valley site and the rest of the deployments. Monthly averaged residual currents reveal that the near-bottom currents on the slope flow southwestward throughout the year except in August and September, 2013, from which we speculate that this is a result of the interaction between a mesoscale eddy and the canyon/sag topography. Currents inside the valley within about 10 mab basically flow along slope and in the layers above the 10 mab the currents are northwestward, that is, from the deep ocean to the shelf. The monthly mean current vectors manifest an Ekman layer-like vertical structure at both sites, which rotate counter-clockwise looking from above. | WU Lunyu XIONG Xuejun LI Xiaolong SHI Maochong GUO Yongqing CHEN Liang | 2016 | Journal of Ocean University of China2016，15，6： | 3 |
| 6 | An ultrahigh strength steel produced through deformation-induced ferrite transformation and Q&P process显示文摘In this work,DIFT technology and Q&P process were combined in order to introduce ultrafine-grained ferrite into the matrix of martensite and retained austenite to develop a new kind of advanced high strength steel,and two kinds of steels were investigated by this novel combined process.The newly designed process resulted in a sophisticated microstructure of a large amount of ferrite(about 5 m in diameter),martensite and a considerable amount of retained austenite for TRIP 780 steel.The ultimate tensile strength can reach about 1200 MPa with elongation above 16% for TRIP 780,that is much higher than the one solely treated by Q&P process.Tensile tests showed that both steels with the novel combined process achieved a good combination of strength and ductility,indicating that the new process is promising for the new generation of advanced high strength steels. | CHEN MingMing WU RiMing LIU HePing WANG Li SHI Jie DONG Han JIN XueJun | 2012 | Science China(Technological Sciences)2012，55，7： | 3 |
| 7 | On the convergence rate of a parallel nonoverlapping domain decomposition method显示文摘In recent years,a nonoverlapping domain decomposition iterative procedure,which is based on using Robin-type boundary conditions as information transmission conditions on the subdomain interfaces,has been developed and analyzed.It is known that the convergence rate of this method is 1-O(h),where h is mesh size.In this paper,the convergence rate is improved to be 1-O(h1/2 H-1/2)sometime by choosing suitable parameter,where H is the subdomain size.Counter examples are constructed to show that our convergence estimates are sharp,which means that the convergence rate cannot be better than 1-O(h1/2H-1/2)in a certain case no matter how parameter is chosen. | QIN LiZhen SHI ZhongCi XU XueJun | 2008 | Science China Mathematics2008，51，8： | 2 |

| 9 | Molecular imaging of advanced atherosclerotic plaques with folate receptor-targeted 2D nanoprobes显示文摘Vulnerable atherosclerotic plaques are responsible for most cardiovascular diseases(CVDs).Folate receptor(FR)positive activated macrophages were thought to be a prominent component in the development of vulnerable plaque.The objective of this study is to develop folate conjugated two-dimensional(2D)Pd@Au nanomaterials(Pd@Au-PEG-FA)for targeted multimodal imaging of the FRs in advanced atherosclerotic plaques.Pharmacokinetic and imaging studies(single photon emission computed tomography(SPECT),computed tomography(CT)and photoacoustic(PA)imaging)were performed to confirm the prolonged blood half-life and enrichment of radioactivity in atherosclerotic plaques.Strong signals were detected in vivo with SPECT,CT and PA imaging in heavy atherosclerotic plaques,which were significantly higher than those of the normal aortas after injection of Pd@Au-PEG-FA.Blocking studies with preinjection of excess FA could effectively reduce the targeting ability of Pd@Au-PEG-FA in atherosclerotic plaques,further demonstrating the specific binding of Pd@Au-PEG-FA for plaque lesions.Histopathological characterization revealed that the signal of probe was in accordance with the high-risk plaques.In summary,the Pd@Au-PEG-FA has favorable pharmacokinetic properties and provides a valuable approach for detecting high-risk plaques in the presence of FRs in atherosclerotic plaques. | Zhide Guo Liu Yang Mei Chen Xuejun Wen Huanhuan Liu Jingchao Li Duo Xu Yuanyuan An Changrong Shi Jindian Li Xinhui Su Zijing Li Ting Liu Rongqiang Zhuang Nanfeng Zheng Haibo Zhu Xianzhong Zhang | 2020 | Nano Research2020，13，1： | 2 |

The martensitic and bainitic transformations were expressed as functions of the tempering parameter. The kinetics of phase transformation of the retained austenite was described by the Avrami equation. Based on the elastoplastic-creeping theory, the constitutive relations for steel tempering process were obtained, and an FEM code was developed. The program was verified with the tempering process of a cylindrical specimen, and the quenching-tempering process of a turbine rotator was analyzed. | Wei Shi, Xuejun Xu, Kefu Yao, Zhuang Liu Mechanical Engineering Department, Tsinghua University, Beijing 100084, China | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 2 |
| 11 | China’s bioenergy industry development roadmap显示文摘Positive development of renewable energy, saving and substitution of fossil energy, promotion of the energy structure adjustment are the inevitable strategy choices of China’s sustainable development. This paper discussed the China’s bioenergy resources status, development targets and technology development roadmaps. China has 136.140 million hm2 of marginal land, which distribute mainly in western and northern regions. There are 1 billion t of crop residues and forestry waste annually, and 300 million t can be used to produce different kinds of bioenergies. And organic waste and manure can generate 50 billion m3 of biogas. The discussed development target indicated that it can construct a biomass oilfield with the capacity of 100 million t/year and reduce 200 million t of CO_2 emission by 2020. The bioenergy technology development roadmap indicated that the bioethanol mainly uses non grain starch and hemicellulose products as raw materials in the near-term (2006-2010). The biodiesel technology will focus on the advanced production technology, FT diesel, liquefaction of biomass and raw material production technology. | Shi Yuanchun Li Shizhong Liu Xuejun | 2009 | Engineering Sciences2009，7，2： | 2 |

| 15 | Mechanism of Surface Vertical Deformation in Parts of the Underground Gas Storage Reservoir of Hutubi, Xinjiang, China显示文摘The Underground Gas Storage( UGS) in Hutubi( HTB),Xinjiang is the largest gas storage reservoir in China and it has significance for coordinating the gas supply and demand relationship,peak-load regulation,implementation of strategic reserves,national security, and social economic sustainable development. Therefore, the deformation monitoring and simulation analysis of UGS operation has important technical support and reference value for the stability and safe operation of the underground gas storage. In this paper,we use the elevation data obtained from 7 periods of second-order leveling surveys in the Hutubi underground gas storage area in 2013- 2015 to analyze the influence of gas well pressure on the vertical deformation of the underground gas storage reservoir.Research has shown that the absolute vertical subsidence rate is approximately in the range from 11. 8mm to 16. 1mm and the relative subsidence change is about 4. 3mm,near the surface deformation of Hutubi underground gas storage area except for the annual subsidence rate of- 2. 86 mm by the basic influence of uplift of the Tianshan Mountains.Groundwater over-extraction in the Hutubi area also has an impact on the vertical variation of the surface in this region. The land surface change per unit pressure of gas storage has an impact of about 0. 625mm- 1. 125 mm. 17 scenes Terra SAR-X radar images acquired from August,2013 to August,2014 are exploited by Small Baseline Subset( SBAS) In SAR method to obtain the surface deformation time series during the operation of UGS in Hutubi,meanwhile combined with the pressure data of injection / productionwells,the multi-point source Mogi model is used to simulate the UGS deformation field in Hutubi. The results show that the deformation characteristics of the whole UGS area is a discontinuous distribution with the peak deformation value of 10 mm and- 8mm in the satellite line of sight( LOS) during gas injection and production,respectively and the retrieved deformation sequences correspond very well to the gas injection / production pressure changes. Based on the multi- point source Mogi model, we simulate the deformation process of UGS,HTB,and with the adaptive forward search method,the radius and depth of point source are obtained. The simulated results indicate that when the average injection / production pressure of UGS,HTB is 18 MPa and 15 MPa, LOS deformation is up to 7mm and- 4mm,respectively,and surface deformation is related to the density of gas injection( production) wells. The UGS gas distribution is not uniform,indicating that the structure of underground gas storage is complex. Thus using a more elaborate geomechanical model and other deformation observation data will be helpful for better simulating the UGS internal structure and explaining the mechanism of deformation. | Li Jie Li Rui Wang Xiaoqiang Shi Xinpu Qiao Xuejun Zheng Liming Abudutayier.
