1A scientometric review of biochar research in the past 20 years(1998-2018)显示文摘Biochar is the carbon-rich product obtained from the thermochemical conversion of biomass under oxygen-limited conditions.Biochar has attained extensive attention due to its agronomical and environmental benefits in agro-ecosystems.This work adopts the scientometric analysis method to assess the development trends of biochar research based on the literature data retrieved from the Web of Science over the period of 1998-2018.By analysing the basic characteristics of 6934 publications,we found that the number of publications grew rapidly since 2010.Based on a keyword analysis,it is concluded that scholars have had a fundamental recognition of biochar and preliminarily found that biochar application had agronomic and environmental benefits during the period of 1998-2010.The clustering results of keywords in documents published during 2011-2015 showed that the main research hotspots were“biochar production”,“biochar and global climate change”,“soil quality and plant growth”,“organic pollutants removal”,and“heavy metals immobilization”.While in 2016-2018,beside these five main research hotspots,“biochar and composting”topic had also received greater attention,indicating that biochar utilization in organic solid waste composting is the current research hotspot.Moreover,updated reactors(e.g.,microwave reactor,fixed-bed reactor,screw-feeding reactor,bubbling fluidized bed reactor,etc.)or technologies(e.g.,solar pyrolysis,Thermo-Catalytic Reforming process,liquefaction technology,etc.)applied for efficient energy production and modified biochar for environmental remediation have been extensively studied recently.The findings may help the new researchers to seize the research frontier in the biochar field.Ping Wu Syed Tahir Ata-Ul-Karim Bhupinder Pal Singh Hailong Wang Tongliang Wu Cun Liu Guodong Fang Dongmei Zhou Yujun Wang Wenfu Chen 2019Biochar2019,1,1:36

3Application of LICOM to the numerical study of the water exchange between the South China Sea and its adjacent oceans显示文摘On the basis of 900-year integration of a global ocean circulation model—LICOM driven by ECMWF reanalysis wind data with uni-form 0.5°-grids, a quantitative estimate of the annual and monthly mean water exchange of the South China Sea (SCS) with its adjacentoceans through 5 straits is obtained. Among them, the annual transport is the largest in the Luzon Strait, then in the Taiwan Strait, andthen in the Sunda Shelf, in the Balabac Strait and in the Mindoro Strait in turn, the largest monthly transport variation appears in theLuzon Strait and Sunda shelf. It is shown that the mass transport through the Taiwan Strait is affected by monsoon, while the transportthrough the Luzon Strait may be associated with the bifurcation position of the North Equatorial Current off the east Philippines shore;the transports in the Luzon Strait and Sunda Shelf are out of phase in direction but well correlated in magnitude. The annual andmonthly mean heat and salinity exchange of the SCS through the straits are also calculated and shown to be in phase with the masstransport. The Kuroshio water carries about 0.43 PW heat transport and 151.33 kt/s salinity transport into the SCS, while most of themis carried out of the SCS through the Taiwan Strait and Sunda Shelf annually. The further model integration based on the 900-year inte-gration for another 44 a from 1958 to 2001 driven by real wind data (ERA40 data) shows that the monthly mean mass transport viathese straits varies annually with a large variation range, which may be associated with the seasonal and interannual variations in thecurrent field and sea surface height in the SCS. The mean mass transport through the Taiwan Strait, Luzon Strait, Mindoro Strait, Bal-abac Strait and Sunda Shelf is 2.012 × 106, -4.063 × 106, -0.124 × 106, -0.083 × 106 and 2.258 × 106 m3/s, respectively.CAI Shuqun LIU Hailong LI Wei LONG Xiaomin 2005Acta Oceanologica Sinica2005,24,4:24

5HiQoS:An SDN-Based Multipath QoS Solution显示文摘Today's Internet architecture provides only 'best effort' services,thus it cannot guarantee quality of service(QoS) for applications.Software Defined Network(SDN)is a new approach to computer networking that separates control plane and forwarding planes,and has the advantage of centralized control and programmability.In this paper,we propose HiQoS that provides QoS guarantees using SDN.Moreover,HiQoS makes use of multiple paths between source and destination and queuing mechanisms to guarantee QoS for different types of traffic.Experimental results show that our HiQoS scheme can reduce delay and increase throughput to guarantee QoS.Very importantly,HiQoS recovers from link failure very quickly by rerouting traffic from failed path to other available path.YAN Jinyao ZHANG Hailong SHUAI Qianjun LIU Bo GUO Xiao 2015China Communications2015,12,5:19
6A quasi-global 1/10° eddy-resolving ocean general circulation model and its preliminary results显示文摘In this study,a quasi-global(excluding the Arctic Ocean) eddy-resolving ocean general circulation model(OGCM) is established based on the latest version of the LASG/IAP Climate system Ocean Model(LICOM2.0).The horizontal resolution and vertical resolution are increased to 1/10° and 55 layers,respectively.Forced by the surface fluxes from the reanalysis and observed data,the model has been integrated for approximately 20 model years(20 a).During the last 8 a,the model is driven by daily mean wind stresses from QuikSCAT and heat fluxes from reanalysis data from 2000 to 2007.The basic performance of the OGCM is analyzed using the last 8 a simulation output.Compared with the simulation of the coarse-resolution OGCM,the eddy-resolving OGCM not only better simulates the spatial-temporal features of mesoscale eddies and the paths and positions of western boundary currents but also reproduces the large meander of the Kuroshio Current and its interannual variability.Another aspect,namely,the complex structures of equatorial Pacific currents and currents in the coastal ocean of China,are better captured due to the increased horizontal and vertical resolution.YU YongQiang LIU HaiLong LIN PengFei 2012Chinese Science Bulletin2012,57,30:18
7Biomarker reconstruction of phytoplankton productiv-ity and community structure changes in the middle Okinawa Trough during the last 15 ka显示文摘Biomarkers have been widely used to reconstruct phytoplankton productivity and community structure changes, and this method has been applied for the first time in the middle Okinawa Trough during the transition from the last deglaciation to the Holocene. The total content of all marine phytoplankton biomarkers, used as a total productivity indicator, reveals higher productivity during the deglaciation. The ratios of the biomarkers are used as community structure indicators which show that, compared with the Holocene, the contribution from haptophytes decreased while the contributions from diatoms and dinoflagellates increased during the deglaciation. The increased productivity during the deglacia- tion was likely caused by the stronger winter monsoon. Also increased nutrient supply from terrestrial sources contributes to the higher productivity due to lower sea-level, which is consistent with higher terrestrial biomarker (long-chain n-alkanols) content. These changes in the nutrient supply also con- tributed to the community structure changes in the Okinawa Trough.XING Lei ZHAO MeiXun ZHANG HaiLong LIU YanGuang SHI XueFa 2008Chinese Science Bulletin2008,53,16:17

9The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:14

11Heterotic Group Classification of 63 Inbred Lines and Hybrid Purity Identification by Using SSR Markers in Winter Cabbage(Brassica Oleracea L. var. capitata)显示文摘Winter cabbage is an important crop cultivated through winter in the region near the Yangtze River, enabling the supply of fresh cabbage there at that time of year. However, a problem has emerged regarding the newly developed parents of winter cabbage, which is completely different from spring and autumn cabbage, namely, how to combine these parents to breed an elite hybrid. To classify the heterotic groups and improve the efficiency of parent selection in winter cabbage breeding, 20 polymorphic SSR markers were selected to screen 63 winter cabbage inbred lines. Seventeen pairs among the 20 SSR markers amplified polymorphic bands. These primers amplified two to six bands,with an average of 2.8 bands per primer, and a total of 47 polymorphic bands were generated in the 63 inbred lines. These lines included flatheaded morphotype and round-headed morphotype, thus they were separately classified into heterotic groups based on the SSR markers. The flat-headed morphotype contained 21 inbred lines and was classified into three heterotic groups, named Hanchun 4, Jiali, and Dongsheng, in accordance with the representative germplasm contained in each group. The round-headed morphotype contained 42 inbred lines and was classified into five heterotic groups, named Parte, Bejo1039, YK-143, SCA002, and Golden B90. Meanwhile, parent analysis of 20 developed elite combinations showed that their parents were all distributed in different heterotic groups, indicating that the group classification was reasonable,which can provide a basis for further parent selection in winter cabbage breeding. Furthermore, polymorphic SSR primers were successfully used to identify the hybrid purity of three elite varieties.LI Xing YU Hailong LI Zhiyuan LIU Xiaoping FANG Zhiyuan LIU Yumei YANG Limei ZHUANG Mu LV Honghao ZHANG Yangyong 2018Horticultural Plant Journal2018,4,4:11
12In-line imaging measurements of particle size,velocity and concentration in a particulate two-phase flow显示文摘A novel method is developed for in-line measurements of particle size, velocity and concentration in a dilute, particulate two-phase flow based on trajectory image processing. The measurement system consists of a common industrial CCD camera, an inexpensive LED light and a telecentric lens. In this work,the image pre-processing steps include stitching, illumination correction, binarization, denoising, and the elimination of unreal and defocused particles. A top-hat transformation is found to be very effective for the binarization of images with non-uniform background illumination. Particle trajectories measured within a certain exposure time are used to directly obtain particle size and velocity. The particle concentration is calculated by using the statistics of recognized particles within the field of view. We validate our method by analyzing experiments in a gas-droplet cyclone separator. This in-line image processing method can significantly reduce the measurement cost and avoid the data inversion process involved in the light scattering method.Xiaozhen Chen Wu Zhou Xiaoshu Cai Mingxu Su Hailong Liu 2014Particuology2014,12,2:10
13The HY-2 satellite and its preliminary assessment显示文摘The HY-2 satellite was successfully launched on 16 August 2011.It carried four microwave instruments into space for operationally observing dynamic ocean environment parameters on a global scale.The HY-2 satellite altimeter provides sea surface height(SSH),significant wave height(SWH),sea surface wind(SSW)speed,and polar ice sheet elevation,while the HY-2 satellite scatterometer provides SSW fields.At the same time,other oceanic and atmospheric parameters such as sea surface temperature(SST)and wind speed,water vapor and liquid water content can also be obtained by its onboard scanning microwave radiometer.In this paper,we show the data processing methods of the HY-2 satellite’s payloads.The preliminary results show that wind vector,SSH,SWH,and SST conform to the designed technical specifications.Xingwei Jiang Mingsen Lin Jianqiang Liu Youguang Zhang Xuetong Xie Hailong Peng Wu Zhou 2012International Journal of Digital Earth2012,5,3:10
14Mechanical and dielectric properties of porous and wave-transparent Si3N4–Si3N4 composite ceramics fabricated by 3D printing combined with chemical vapor infiltration显示文摘Porous Si3N4–Si3N4 composite ceramics were fabricated by 3D printing combined with low-pressure chemical vapor infiltration(CVI).This technique could effectively improve the designability of porous Si3N4 ceramics and optimize the mechanical and dielectric properties.The effects of process parameters including the deposition time and heat treatment on the microstructure and properties of porous Si3N4–Si3N4 composite ceramics were studied.The study highlights following:When CVI processing time was increased from 0 to 12 h,the porosity decreased from68.65%to 26.07%and the density increased from 0.99 to 2.02 g/cm3.At the same time,the dielectric constant gradually increased from 1.72 to 3.60;however,the dielectric loss always remained less than0.01,indicating the excellent electromagnetic(EM)wave-transparent performance of porous Si3N4–Si3N4 composite ceramics.The maximum flexural strength of 47±2 MPa was achieved when the deposition time attained 6 h.After heat treatment,the porosity increased from 26.07%to 36.02%and the dielectric constant got a slight increase from 3.60 to 3.70 with the dielectric loss still maintaining lower than 0.01.It has been demonstrated that the porous Si3N4–Si3N4 composite ceramics are a promising structural and EM wave-transparent material suitable for high temperature service.Zanlin CHENG Fang YE Yongsheng LIU Tianlu QIAO Jianping LI Hailong QIN Laifei CHENG Litong ZHANG 2019Journal of Advanced Ceramics2019,8,3:10
15Solidification Simulation of Investment Castings of Single Crystal Hollow Turbine Blade显示文摘The three-dimensional solidification simulation of the investment castings of single crystal hollow turbine blade at the withdrawal rates of 2 mm/min, 4.5 mm/min and 7 mm/min has been performed with the finite element thermal analysis. The calculated results are in accordance with the experimental ones. The results show that with the increase of withdrawal rate the concave curvature of the liquidus isotherm is larger and larger, and the temperature gradients of the blades increase. No effects of withdrawal rate on the distribution of the temperature gradients of the starter and helical grain selector of the blades are observed at withdrawal rates of 2 mm/min, 4.5 mm/min and 7 mm/min. The relatively high temperature gradient between 500℃/cm and 1000℃/cm in the starter and helical grain selector is obtained at three withdrawal rates.Jiarong LI, Shizhong LIU, Hailong YUAN and Zhengang ZHONGNational Key Laboratory of Advanced High Temperature Structural Materials, Beijing Institute of Aeronautical Materials, Beijing 100095, China 2003Journal of Materials Science & Technology2003,19,6:9
16LICOM Model Datasets for the CMIP6 Ocean Model Intercomparison Project显示文摘The datasets of two Ocean Model Intercomparison Project(OMIP)simulation experiments from the LASG/IAP Climate Ocean Model,version 3(LICOM3),forced by two different sets of atmospheric surface data,are described in this paper.The experiment forced by CORE-II(Co-ordinated Ocean–Ice Reference Experiments,Phase II)data(1948–2009)is called OMIP1,and that forced by JRA55-do(surface dataset for driving ocean–sea-ice models based on Japanese 55-year atmospheric reanalysis)data(1958–2018)is called OMIP2.First,the improvement of LICOM from CMIP5 to CMIP6 and the configurations of the two experiments are described.Second,the basic performances of the two experiments are validated using the climatological-mean and interannual time scales from observation.We find that the mean states,interannual variabilities,and long-term linear trends can be reproduced well by the two experiments.The differences between the two datasets are also discussed.Finally,the usage of these data is described.These datasets are helpful toward understanding the origin system bias of the fully coupled model.Pengfei LIN Zhipeng YU Hailong LIU Yongqiang YU Yiwen LI Jirong JIANG Wei XUE Kangjun CHEN Qian YANG Bowen ZHAO Jilin WEI Mengrong DING Zhikuo SUN Yaqi WANG Yao MENG Weipeng ZHENG Jinfeng MA 2020Advances in Atmospheric Sciences2020,37,3:9

19Meso-scale eddy in the South China Sea simulated by an eddy-resolving ocean model显示文摘Mesoscale eddies(MEs) in the South China Sea(SCS) simulated by a quasi-global eddy-resolving ocean general circulation model are evaluated against satellite data during 1993–2007. The modeled ocean data show more activity than shown by the satellite data and reproduces more eddies in the SCS. A total of 345(428) cyclonic eddies(CEs) and 330(371) anti-cyclonic eddies(AEs) generated for satellite(model) data are identified during the study period, showing increase of ~24% and ~12% for the model data, respectively. Compared with eddies in satellite, the simulated eddies tend to have smaller radii, larger amplitudes, a slightly longer lifetime, faster movement and rotation speed, a slightly larger nonlinear properties(U/c) in the model. However, the spatial distribution of generated eddies appears to be inhomogeneous, with more CEs in the northern part of SCS and fewer AEs in the southern part. This is attributed to the exaggerated Kuroshio intrusion in the model because the small islands in the Luzon Strait are still not well resolved although the horizontal resolution reaches(1/10)°. The seasonal variability in the number and the amplitude of eddies generated is also investigated.FENG Baoxin LIU Hailong LIN Pengfei WANG Qi 2017Acta Oceanologica Sinica2017,36,5:8
20Utilization of Ogura CMS germplasm with the clubroot resistance gene by fertility restoration and cytoplasm replacement in Brassica oleracea L显示文摘Clubroot disease,a major plant root disease caused by Plasmodiophora brassicae,has become one of the most destructive diseases among cultivated cruciferous vegetables.However,clubroot-resistant Brassica oleracea materials are rare.A few clubroot-resistant cabbage varieties are available on the market,but all are Ogura cytoplasmic male sterile(CMS)types.Therefore,in this study,to reutilize the clubroot-resistant Ogura CMS germplasm of cabbage,a new fertility-restored Ogura CMS material,16Q2-11,was used as a bridge to transfer the clubroot resistance(CR)gene from the Ogura CMS cytoplasm to the normal cytoplasm by a two-step method(a fertility restoration and cytoplasm replacement method).In the first cross for fertility restoration of Ogura CMS clubroot-resistant cabbage(FRCRC),16Q2-11 was used as a restorer to cross with Ogura CMS materials containing the CR gene CRb2.Eleven Rfo-positive progenies were generated,of which four contained CRb2:F8-514,F8-620,F8-732 and F8-839.After inoculation with race 4 of P.brassicae,these four CRb2-positive individuals showed resistance.Furthermore,F8-514 and F8-839 were then used as male parents in the second cross of FRCRC to cross with cabbage inbred lines,resulting in the successful introgression of the CRb2 gene into the inbred lines.All offspring produced from this step of cross,which had a normal cytoplasm,showed a high resistance to race 4 of P.brassicae and could be utilized for the breeding of clubrootresistant cabbage varieties in the future.This is the first time that the Ogura CMS restorer has been used to restore the fertility of Ogura CMS clubroot-resistant cabbages,which could improve germplasm diversity in cabbage and provide a reference method for using CMS germplasm in Brassica crops.Wenjing Ren Zhiyuan Li Fengqing Han Bin Zhang Xing Li Zhiyuan Fang Limei Yang Mu Zhuang Honghao Lv Yumei Liu Yong Wang Hailong Yu Yangyong Zhang 2020Horticulture Research2020,7,1:7
