| 1 | Research on the reconstruction method of porous media using multiple-point geostatistics显示文摘The pore structural characteristics have been the key to the studies on the mechanisms of fluids flow in porous media. With the development of experimental technology, the modern high-resolution equipments are capable of capturing pore structure images with a resolution of microns. But so far only 3D volume data of millimeter-scale rock samples can be obtained losslessly. It is necessary to explore the way of virtually reconstructing larger volume digital samples of porous media with the representative structural characteristics of the pore space. This paper proposes a reconstruction method of porous media using the structural characteristics captured by the data templates of multiple-point geostatistics. In this method, the probability of each structural characteristic of a pore space is acquired first, and then these characteristics are reproduced according to the probabilities to present the real structural characteristics in the reconstructed images. Our experimental results have shown that: (i) the deviation of LBM computed permeability respectively on the virtually reconstructed sandstone and the original sample is less than 1.2%; (ii) the reconstructed sandstone and the original sample have similar structural characteristics demonstrated by the variogram curves. | ZHANG Ting 1,2,3, LI DaoLun 1,2 , LU DeTang 1,2 & YANG JiaQing 1,2 1 Department of Modern Mechanics, University of Science and Technology of China, Hefei 230027, China 2 Research Center of Oil and Natural Gas, University of Science and Technology of China, Hefei 230027, China 3 The 28th Research Institute, China Electronics Technology Group Corporation, Nanjing, 210007, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 10 |
| 2 | OsADR3 increases drought stress tolerance by inducing antioxidant defense mechanisms and regulating OsGPX1 in rice(Oryza sativa L.)显示文摘The C (Cys) 2H (His) 2-type transcription factor is one of the most important transcription factors in plants and plays a regulatory role in the physiological responses of rice to abiotic stresses.A novel rice C2H2-type zinc finger protein,abscisic acid (ABA)-drought-reactive oxygen species (ROS) 3 (OsADR3),was found to confer drought stress tolerance by enhancing antioxidant defense and regulating Os GPX1.Overexpression of OsADR3 in rice increased tolerance to drought stress by increasing ROS scavenging ability and ABA sensitivity.In contrast,CRISPR/Cas9-mediated knockout of osadr3 increased the sensitivity of rice to drought and oxidative stress.An exogenous ROS-scavenging reagent restored the droughtstress tolerance of osadr3-CRISPR plants.Global transcriptome analysis suggested that OsADR3 increased the expression of Os GPX1 under drought stress.Electrophoretic mobility shift,yeast one-hybrid,and dualluciferase reporter assays revealed that OsADR3 modified the expression of Os GPX1 by directly binding to its promoter.Knockdown of Os GPX1 repressed ROS scavenging ability under drought stress in OsADR3-overexpression plants.These findings suggest that OsADR3 plays a positive regulatory role in droughtstress tolerance by inducing antioxidant defense and associated with the ABA signaling pathway in rice. | Jiaming Li Minghui Zhang Luomiao Yang Xinrui Mao Jinjie Li Lu Li Jingguo Wang Hualong Liu Hongliang Zheng Zichao Li Hongwei Zhao Xianwei Li Lei Lei Jian Sun Detang Zou | 2021 | The Crop Journal2021，9，5： | 2 |

| 5 | Transient pressure analysis in porous and fractured fractal reservoirs显示文摘Fluid flow in porous and fractured fractal reservoirs is studied in the paper. The basic formulae of seepage velocity,permeability and porosity in both porous and fractured fractal media are developed. The pressure diffusion equation of slightly compressible fluid in fractal reservoirs is derived. The analytical solutions of the transient pressure are given for the line-source well and the well with well-bore storage and skin factor. The typical curves of pressure and the derivative of pressure are established,along with the interpretation of the well-testing method via type-curve matching. In addition,3-D pressure diffusion equations for anisotropic fractal media are given in both Cartesian coordinates and Cy-lindrical coordinates. | KONG XiangYan LI DaoLun LU DeTang | 2009 | Science China(Technological Sciences)2009，52，9： | 1 |

| 13 | Propagation of liquid surface waves over finite graphene structured arrays of cylinders显示文摘Based on the multiple scattering method,this paper investigates a benchmark problem of the propagation of liquid surface waves over finite graphene (or honeycomb) structured arrays of cylinders.Comparing the graphene structured array with the square structured and with triangle structured arrays,it finds that the finite graphene structure can produce more complete band gaps than the other finite structures,and the finite graphene structure has less localized ability than the other finite structures. | Xuemei Liu,1,2 Yong Wei,1 Sheng Li,1 Yousheng Xu,1,Detang Lu,3 and Boming Yu 4 1) Department of Physics,Zhejiang Normal University,Jinhua 321004,Zhejiang,China 2) Hangzhou No.14 Middle School,Hangzhou 310006,China 3) Department of Modern Mechanics,University of Science and Technology of China,Hefei 230027,China 4) School of Physics,Huazhong University of Science and Technology,Wuahn 430074,China | 2011 | Theoretical & Applied Mechanics Letters2011，1，5： | 0 |
| 14 | Numerical investigation of positive dihedral application conditions in compressor cascades显示文摘This study attempts to make a contribution to the understanding of dihedral application conditions and their aerodynamic mechanisms.The present efforts have finished contrastive investigations on several dihedral blades to their corresponding straight ones with different geometric or aerodynamic conditions including aspect ratio,solidity,aerofoil turning angle,inlet boundary layer configuration and inlet Mach number.A dihedral with the angle between the suction side and the endwall to be obtuse,i.e.,positive dihedral,is chosen.The result reveals the dihedral application conditions consist of aerofoil turning angle,inlet boundary layer,inlet Mach number and so on.The further analysis indicates:in a transonic cascade,two considerations are needed on the contrastive relationship between intensities of the two shocks,namely detached shock and passage shock,and the interaction of the shocks with the corner separation. | Detang Zengn Meiyuan Li Yongjun Zhang Chunqing Tan | 2015 | Propulsion and Power Research2015，4，2： | 0 |
