| 1 | Mycorrhizal symbiosis modulates the rhizosphere microbiota to promote rhizobia–legume symbiosis显示文摘Plants establish symbioses with mutualistic fungi,such as arbuscular mycorrhizal(AM)fungi,and bacteria,such as rhizobia,to exchange key nutrients and thrive.Plants and symbionts have coevolved and represent vital components of terrestrial ecosystems.Plants employ an ancestral AM signaling pathway to establish intracellular symbioses,including the legume–rhizobia symbiosis,in their roots.Nevertheless,the relationship between the AM and rhizobial symbioses in native soil is poorly understood.Here,we examined how these distinct symbioses affect root-associated bacterial communities in Medicago truncatula by performing quantitative microbiota profiling(QMP)of 16S rRNA genes.We found that M.truncatula mutants that cannot establish AM or rhizobia symbiosis have an altered microbial load(quantitative abundance)in the rhizosphere and roots,and in particular that AM symbiosis is required to assemble a normal quantitative root-associated microbiota in native soil.Moreover,quantitative microbial co-abundance network analyses revealed that AM symbiosis affects Rhizobiales hubs among plant microbiota and benefits the plant holobiont.Through QMP of rhizobial rpoB and AM fungal SSU rRNA genes,we revealed a new layer of interaction whereby AM symbiosis promotes rhizobia accumulation in the rhizosphere of M.truncatula.We further showed that AM symbiosis-conditioned microbial communities within the M.truncatula rhizosphere could promote nodulation in different legume plants in native soil.Given that the AM and rhizobial symbioses are critical for crop growth,our findings might inform strategies to improve agricultural management.Moreover,our work sheds light on the co-evolution of these intracellular symbioses during plant adaptation to native soil conditions. | Xiaolin Wang Huan Feng Yayu Wang Mingxing Wang Xingguang Xie Huizhong Chang Like Wang Jicheng Qu Kai Sun Wei He Chunyan Wang Chuanchao Dai Zhaohui Chu Changfu Tian Nan Yu Xuebin Zhang Huan Liu Ertao Wang | 2021 | Molecular Plant2021，14，3： | 6 |
| 2 | Influence of the Addition of Cotton Stalk during Co-pyrolysis with Sewage Sludge on the Properties, Surface Characteristics, and Ecological Risks of Biochars显示文摘Sewage sludge produced by municipal sewage treatment plants can potentially be used as a biomass energy source because of its high organic content.Presently,the conversion and utilization of rapidly growing amounts of sewage sludge represent an urgent challenge in China.Thermal conversion of sewage sludge to biochar through pyrolysis is a promising solution to this problem.However,biochar produced by pyrolysis of sewage sludge alone has a poor pore structure as a result of its low C content and high ash content.Furthermore,it is enriched in heavy metals that may pose high ecological risks.In this study,we addressed these issues through co-pyrolysis of sewage sludge and cotton stalks(1:1,wt./wt.)at different pyrolysis temperatures ranging from 350℃ to 750℃.The properties and surface characteristics of the biochars were investigated.Meanwhile,the transformation behavior of heavy metals during the co-pyrolysis process was studied,and the potential ecological risks of heavy metals in biochars were assessed.The results showed that elevated pyrolysis temperatures reduced the biochar yield and C content of the biochars,whereas such temperatures increased the pH value and ash content of the biochars.The biochars prepared at different pyrolysis temperatures were all mesoporous materials.The elevated temperatures promoted the transformation of heavy metals from mobile fractions to stable ones,thus resulting in a significant decrease in the ecological risks.In summary,co-pyrolysis of sewage sludge with cotton stalks proved to be a feasible method for the conversion and utilization of sewage sludge. | WANG Zhipu WANG Jian XIE Like ZHU Henan SHU Xinqian | 2019 | Journal of Thermal Science2019，28，4： | 5 |
| 3 | Flight safety oriented ice shape modulation using distributed plasma actuator units显示文摘Ice accretion on the wings seriously threatens the flight safety of an aircraft.From the perspectives of ensuring flight safety and saving power consumption,the ice shape modulation method using distributed plasma is proposed.Distributed plasma actuator units are designed to modulate the spanwise continuous ice at the leading edge into periodically segmented ice pieces,forming a wavy leading edge.Both airfoil and scaled aircraft model,with continuous and modulated ice,are experimentally investigated and simulated.Compared with the continuous ice,ice shape modulation can significantly improve the aerodynamic performance,flight control characteristics and flight safety.This method can save about half electric power,which is very beneficial for application. | Yun WU Biao WEI Hua LIANG Like XIE Zhe LI Yinghong LI | 2021 | Chinese Journal of Aeronautics2021，34，10： | 5 |
| 4 | Design and validation of the THMC China-Mock-Up test on buffer material for HLW disposal显示文摘According to the preliminary concept of the high-level radioactive waste(HLW) repository in China,a large-scale mock-up facility,named China-Mock-Up was constructed in the laboratory of Beijing Research Institute of Uranium Geology(BRIUG).A heater,which simulates a container of radioactive waste,is placed inside the compacted Gaomiaozi(CMZ)-Na-bentonite blocks and pellets.Water inflow through the barrier from its outer surface is used to simulate the intake of groundwater.The numbers of water injection pipes,injection pressure and the insulation layer were determined based on the numerical modeling simulations.The current experimental data of the facility are herein analyzed.The experiment is intended to evaluate the thermo-hydro-mechano-chemical(THMC) processes occurring in the compacted bentonite-buffer during the early stage of HLW disposal and to provide a reliable database for numerical modeling and further investigation of engineered barrier system(EBS),and the design of HLW repository. | Yuemiao Liu Like Ma Dan Ke Shengfei Cao Jingli Xie Xingguang Zhao Liang Chena Panpan Zhang | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014，6，2： | 2 |
| 5 | Improving aircraft aerodynamic performance with bionic wing obtained by ice shape modulation显示文摘For Unmanned Aerial Vehicles(UAVs)with limited electrical power to achieve effectively anti-/de-icing at the leading edge of the wing,a strategy of ice shape modulation was proposed.Isolated simulated ice shape pieces printed by 3D printing technology are mounted on a NACA0012 finite wing model,and its lift/drag coefficients and suction-side velocity fields are measured by the six-component force balance and the Particle Imaging Velocimetry(PIV),respectively.The ratio of the spanwise length of a single ice shape piece to chord length and the spanwise length of the non-icing area between the two adjacent single ice shape pieces are defined as dimensionless ice shape length(w/c)and dimensionless modulation ratio(w/λ),respectively.The results indicate that for a fixed w/λ,the wing lift coefficient first increases and then drops with increasing w/c,and a peak value exists when w/c is between 0.1 and 0.2.The lower the w/λis,the higher the wing lift coefficient will be.The periodical variation of the flow separation area along the spanwise direction is attributed on the one hand to the acceleration effect of the flow field in the non-icing area which reduces the separation area,and on the other hand to the cross-flow caused by the streamwise vortices from the non-icing area to the icing area which promotes the mixing of the flow field(similar to vortex generators).The obtained modulation law is verified through flight tests and provides guidance for the use of ice shape modulation scheme for UAVs that cannot be completely anti-/deicing under severe weather conditions. | Like XIE Hua LIANG Haohua ZONG Yun WU Yinghong LI Zhi SU Xuecheng LIU | 2023 | Chinese Journal of Aeronautics2023，36，2： | 1 |
| 6 | Minimizing airfoil drag at low angles of attack with DBD-based turbulent drag reduction methods显示文摘Dielectric Barrier Discharge(DBD)based turbulent drag reduction methods are used to reduce the total drag on a NACA 0012 airfoil at low angels of attack.The interaction of DBD with turbulent boundary layer was investigated,based on which the drag reduction experiments were conducted.The results show that unidirectional steady discharge is more effective than oscillating discharge in terms of drag reduction,while steady impinging discharge fails to finish the mission(i.e.drag increase).In the best scenario,a maximum relative drag reduction as high as 64%is achieved at the freestream velocity of 5 m/s,and a drag reduction of 13.7%keeps existing at the freestream velocity of 20 m/s.For unidirectional discharge,the jet velocity ratio and the dimensionless actuator spacing are the two key parameters affecting the effectiveness.The drag reduction magnitude varies inversely with the dimensionless spacing,and a threshold value of the dimensionless actuator spac-ing of 540(approximately five times of the low-speed streak spacing)exists,above which the drag increases.When the jet velocity ratio smaller than 0.05,marginal drag variation is observed.In con-trast,when the jet velocity ratio larger than 0.05,the experimental data bifurcates,one into the drag increase zone and the other into the drag reduction zone,depending on the value of dimensionless actuator spacing.In both zones,the drag variation magnitude increases with the jet velocity ratio.The total drag reduction can be divided into the reduction in pressure drag and turbulent friction drag,as well as the increase in friction drag brought by transition promotion.The reduction in tur-bulent friction drag plays an important role in the total drag reduction. | Zhi SU Haohua ZONG Hua LIANG Jun LI Like XIE Xuecheng LIU Weiliang KONG Borui ZHENG | 2023 | Chinese Journal of Aeronautics2023，36，4： | 1 |
