| 1 | China’s urban expansion from 1990 to 2010 determined with satellite remote sensing显示文摘Based on the same data source of Landsat TM/ETM+ in 1990s,2000s and 2010s,all urban built-up areas in China are mapped mainly by human interpretation.Mapping results were checked and refined by the same analyst with the same set of criteria.The results show during the last 20 years urban areas in China have increased exponentially more than 2 times.The greatest area of urbanization changed from Northeastern provinces in 1990s to the Southeast coast of China in Jiangsu,Guangdong,Shandong,and Zhejiang in 2010s.Urban areas are mostly converted from croplands in China.Approximately 17750 km 2 croplands were converted into urban lands.Furthermore,the conversion from 2000 to 2010 doubled that from 1990 to 2000.During the 20 years,the most urbanized provinces are Jiangsu,Guangdong,Shandong and Zhejiang.We also analyzed built-up areas,gross domestic production (GDP) and population of 147 cities with a population of greater than 500000 in 2009.The result shows coastal cities and resource-based cities are with high economic efficiency per unit of built-up areas,resource-based cities have the highest population density,and the economic efficiency of most coastal provinces are lower than central provinces and Guangdong.The newly created urban expansion dataset is useful in many fields including trend analysis of urbanization in China;simulation of urban development dynamics;analysis of the relationship among urbanization,population growth and migration;studies of carbon emissions and climate change;adaptation of climate change;as well as land use and urban planning and management. | WANG Lei LI CongCong YING Qing CHENG Xiao WANG XiaoYi LI XueYan HU LuanYun LIANG Lu YU Le HUANG HuaBing GONG Peng | 2012 | Chinese Science Bulletin2012，57，22： | 64 |
| 2 | Risk factors of infected pancreatic necrosis secondary to severe acute pancreatitis显示文摘BACKGROUND: Severe acute pancreatitis(SAP) remains a clinical challenge with considerable morbidity and mortality.An early identification of infected pancreatic necrosis(IPN), a life-threatening evolution secondary to SAP, is obliged for a more preferable prognosis. Thus, the present study was conducted to identify the risk factors of IPN secondary to SAP. METHODS: The clinical data of patients with SAP were retrospectively analyzed. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and the development of IPN secondary to SAP. A receiver operating characteristic(ROC) curve was created for each of the qualified independent risk factors. RESULTS: Of the 115 eligible patients, 39(33.9%) progressed to IPN, and the overall in-hospital mortality was 11.3%(13/115).The early enteral nutrition(EEN)(P=0.0092, OR=0.264), maximum intra-abdominal pressure(IAP)(P=0.0398, OR=1.131)and maximum D-dimer level(P=0.0001, OR=1.006) in the first three consecutive days were independent risk factors associated with IPN secondary to SAP. The area under ROC curve(AUC) was 0.774 for the maximum D-dimer level in the first three consecutive days and the sensitivity was 90% and the specificity was 58% at a cut-off value of 933.5 μg/L; the AUC was 0.831 for the maximum IAP in the first three consecutive days and the sensitivity was 95% and specificity was 58%at a cut-off value of 13.5 mm Hg. CONCLUSIONS: The present study suggested that the maximum D-dimer level and/or maximum IAP in the first three consecutive days after admission were risk factors of IPN secondary to SAP; an EEN might be helpful to prevent the progression of IPN secondary to SAP. | Liang Ji Jia-Chen Lv Zeng-Fu Song Mai-Tao Jiang Le Li Bei Sun | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，4： | 38 |
| 3 | An Investigation of Oxidative DNA Damage in Pharmacy Technicians Exposed to Antineoplastic Drugs in Two Chinese Hospitals Using The Urinary 8-OHdG Assay显示文摘Objective To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals.Methods Urinary 8-OHdG served as a biomarker.5-Fluorouracil (5-FU) concentrations in air,masks and gloves were determined.The spill exposure of each PIVAS technician to antineoplastic drugs was investigated.Eighty subjects were divided into exposed group I,II,and control group I,II.Results 5-FU concentration ratios for gloves and masks in exposed group I were significantly higher than those in exposed group II (P<0.05 or P<0.01).The average urinary 8-OHdG concentrations in exposed group I,control group I,exposed group II,and control group II were 14.69±0.93,10.68±1.07,10.57±0.55,and 11.96±0.73 ng/mg Cr,respectively.Urinary 8-OHdG concentration in exposed group I was significantly higher than that in control group I or that in exposed group II (P<0.01).There was a significant correlation between urinary 8-OHdG concentrations and spill frequencies per technician (P<0.01).Conclusion There was detectable oxidative DNA damage in PIVAS technicians exposed to antineoplastic drugs.This oxidative DNA damage may be associated with their spill exposure experience and contamination of their personal protective equipment. | HUANG Yu Wen JIAN Le ZHANG Mei Bian ZHOU Quan YAN Xiao Feng HUA Xu Dong ZHOU Ying HE Ji Liang | 2012 | Biomedical and Environmental Sciences2012，25，1： | 30 |
| 4 | Research progress on silicon/carbon composite anode materials for lithium-ion battery显示文摘Silicon(Si) has been considered as one of the most promising anode material for the next generation lithium-ion batteries(LIBs) with high energy densities, due to its high theoretical capacity, abundant availability and environmental friendliness. However, silicon materials with low intrinsic electric and ionic conductivity suffer from huge volume variation during lithiation/delithiation processes leading to the pulverization of Si and subsequently resulting in severe capacity fading of the electrodes. Coupling of Si with carbon(C) realizes a favorable combination of the two materials properties, such as high lithiation capacity of Si and excellent mechanical and conductive properties of C, making silicon/carbon composite(Si/C) ideal candidates for LIBs anodes. In this review, recent progresses of Si/C materials utilized in LIBs are summarized in terms of structural design principles, material synthesis methods, morphological characteristics and electrochemical performances by highlighting the material structures. The mechanisms behind the performance enhancement are also discussed. Moreover, other factors that affect the performance of Si/C anodes, such as prelithiation, electrolyte additives, and binders, are also discussed. We aim to present a full scope of the Si/C-based anodes, and help understand and design future structures of Si/C anodes in LIBs. | Xiaohui Shen Zhanyuan Tian Ruijuan Fan Le Shao Dapeng Zhang Guolin Cao Liang Kou Yangzhi Bai | 2018 | Journal of Energy Chemistry2018，27，4： | 29 |
| 5 | Role of autophagy in the pathogenesis of multiple sclerosis显示文摘Autophagy plays an important role in maintaining the cellular homeostasis. One of its functions is to degrade unnecessary organelles and proteins for energy recycling or amino-acids for cell survival. Ablation of autophagy leads to neurodegeneration. Multiple sclerosis(MS), a permanent neurological impairment typical of chronic inflammatory demyelinating disorder, is an auto-immune disease of the central nervous system(CNS). Autophagy is tightly linked to the innate and adaptive immune systems during the autoimmune process, and several studies have shown that autophagy directly participates in the progress of MS or experimental autoimmune encephalomyelitis(EAE, a mouse model of MS). Dysfunction of mitochondria that intensively influences the autophagy pathway is one of the important factors in the pathogenesis of MS. Autophagy-related gene(ATG) 5 and immune-related GTPase M(IRGM) 1 are increased, while ATG16L2 is decreased, in T-cells in EAE and active relapsing-remitting MS brains. Administration of rapamycin, an inhibitor of mammalian target of rapamycin( m TOR), ameliorates relapsing-remitting EAE. Inflammation and oxidative stress are increased in MS lesions and EAE, but Lamp2 and the LC3-II/LC3-I ratio are decreased. Furthermore, autophagy in various glial cells plays important roles in regulating neuro-inflammation in the CNS, implying potential roles in MS. In this review, we discuss the role of autophagy in the peripheral immune system and the CNS in neuroinflammation associated with the pathogenesis of MS. | Peizhou Liang Weidong Le | 2015 | Neuroscience Bulletin2015，31，4： | 19 |
| 6 | Toxicity of the brominated flame retardant tris-(2,3-dibromopropyl) isocyanurate in zebrafish (Danio rerio)显示文摘Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a heterocyclic brominated flame retardant that was recently detected in the environment in China.TBC is semi-volatile and can accumulate in the lipid of some species,but little is known about its effect on aquatic organisms.We exposed adult zebrafish to 0,0.25,1 and 4mg/L TBC for 28 d and measured the effect on survival,growth,histopathology,hormone levels,enzyme activity,and gene expression.TBC exposure had no effect on survival or growth.We observed significant damage to the liver and gill,including hepatocellular swelling and fatty degeneration in the liver as well as proliferation and edema of epithelial cells in the gills.In addition,exposure to 4mg/L TBC induced proliferation of goblet cells in the intestine of both sexes,acellular areas in the testis,and thinly scattered vitellogenic granules in vitellogenic oocytes.TBC exposure had no effect on the levels of thyroid hormones,testosterone,estradiol,liver superoxide dismutase activity,malondialdehyde content,and brain cholinesterase activity.By contrast,hepatic vitellogenin and cytochrome P4501A gene expression was significantly down-regulated in both male and female zebrafish in response to TBC exposure.Our results suggest that exposure to TBC causes a variety of potential reproductive and endocrine toxic effects. | ZHANG Xu LI Juan CHEN MinJie WU Le ZHANG Chi ZHANG Jie ZHOU QunFang LIANG Yong | 2011 | Chinese Science Bulletin2011，56，15： | 13 |
| 7 | Whole-Genome Resequencing of a Worldwide Collection of Rapeseed Accessions Reveals the Genetic Basis of Ecotype Divergence显示文摘Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of 'Darmor-bzh'and 'Tapidor,'respectively.We generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of B.napus by calculating the genetic diversity and linkage disequilibrium parameters.Selective-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding. | Dezhi Wu Zhe Liang Tao Yan Ying Xu Lijie Xuan Juan Tang Gang Zhou Ulrike Lohwasser Shuijin Hua Haoyi Wang Xiaoyang Chen Qian Wang Le Zhu Antony Maodzeka Nazim Hussain Zhilan Li Xuming Li Imran Haider Shamsi Ghulam Jilani Linde Wu Hongkun Zheng Guoping Zhang Boulos Chalhoub Lisha Shen Hao Yu Lixi Jiang | 2019 | Molecular Plant2019，12，1： | 10 |
| 8 | Mechanical Properties and Microstructure of In Situ TiB_2-7055 Composites显示文摘In order to fabricate a kind of high strength particulate reinforced aluminum-matrix composites, the high strength aluminum alloy 7055 was selected as a matrix. Composites reinforced with varying amounts of TiB2 particles were synthesized using the in situ method, and their mechanical properties and microstructure were analyzed. It is found that the in situ TiB2 particles sized from 50 to 400 nm uniformly disperse in the matrix. With the weight fraction of TiB2 particles increasing, the elastic modulus as well as the yield strength and the ultimate tensile strength increase, while the ductility decrease. The improvement of strength could be attributed to good bonding between TiB2 and the matrix, and also the TiB2 particles act as a barrier to dislocation. | CHEN dong LE Yong-kang BAI Liang MA Nai-heng LI Xian-feng WANG Hao-wei | 2006 | Chinese Journal of Aeronautics2006，19，B12： | 8 |
| 9 | Modified k-ω model using kinematic vorticity for corner separation in compressor cascades显示文摘A new method of modifying the conventional k-ω turbulence model for corner separation is proposed in this paper. The production term in the ω equation is modified using kinematic vorticity considering fluid rotation and deformation in complex geometric boundary conditions. The corner separation flow in linear compressor cascades is calculated using the original k-ω model, the modified k-ω model and the Reynolds stress model(RSM). The numerical results of the modified model are compared with the available experimental data, as well as the corresponding results of the original k-ω model and RSM. In terms of accuracy, the modified model, which significantly improves the performance of the original k-ω model for predicting corner separation, is quite competitive with the RSM. However, the modified model, which has considerably lower computational cost, is more robust than the RSM. | LIU YangWei YAN Hao FANG Le LULiPeng LI QiuShi SHAO Liang | 2016 | Science China(Technological Sciences)2016，59，5： | 7 |

| 11 | A Mini Review on Nanocarbon-Based 1D Macroscopic Fibers:Assembly Strategies and Mechanical Properties显示文摘Nanocarbon-based materials, such as carbon nanotubes(CNTs) and graphene have been attached much attention by scientific and industrial community. As two representative nanocarbon materials, one-dimensional CNTs and twodimensional graphene both possess remarkable mechanical properties. In the past years, a large amount of work have been done by using CNTs or graphene as building blocks for constructing novel, macroscopic, mechanically strong fibrous materials. In this review, we summarize the assembly approaches of CNT-based fibers and graphene-based fibers in chronological order, respectively. The mechanical performances of these fibrous materials are compared, and the critical influences on the mechanical properties are discussed. Personal perspectives on the fabrication methods of CNT-and graphene-based fibers are further presented. | Liang Kou Yingjun Liu Cheng Zhang Le Shao Zhanyuan Tian Zengshe Deng Chao Gao | 2017 | Nano-Micro Letters2017，9，4： | 6 |
| 12 | Effect of Gd addition on mechanical and microstructural properties of Mg-xGd-2.6Nd-0.5Zn-0.5Zr cast alloys显示文摘The Mg-xGd-2.6Nd-0.5Zn-0.5Zr(x=0,3.0,4.5 and 6.0,wt.%)alloys were prepared by gravity casting and then T6 treatment.Microstructures of the alloy were observed using optical microscopy and scanning electron microscopy.Results show that the as-cast alloys contained network Mg3Gd phases,blocky and needle-like Mg12(Nd,Gd)phases.The a(Zr)particle inclusions in the a(Mg)matrix are also observed.Content of the secondary phases decreases as Gd content increases.Tensile test results show that the tensile and yield strengths of all the alloys increase as Gd content increases under the as-cast and T6 conditions,but the elongation exhibits the opposite trend.The blocky Mg12(Nd,Gd)phases appear and act as crack initiator and deteriorates the experimental alloys’ductility with the increase of Gd content,especially as Gd content increases to 6.0 wt.%,so the Mg-6.0Gd-2.6Nd-0.5Zn-0.5Zr alloy has the lowest elongation value compared to the other alloys studied.After T6 treatment,the Mg-4.5Gd-2.6Nd-0.5Zn-0.5Zr alloy exhibits the optimal mechanical properties both at room temperature and 250℃. | Liang Zhan Yi-zhi Le Zhi-jun Feng Yan-chun Lou Ming Ruan Hua-wen Li | 2020 | China Foundry2020，17，3： | 6 |
| 13 | Seasonal Variation of δ^13C of Four Tree Species: A Biological Integrator of Environmental Variables显示文摘Foliar δ13C values, an indicator of long-term intercellular carbon dioxide concentration and, thus,of long-term water use efficiency (WUE) in plants, were measured for Pinus massoniana Lamb., P. elliottii Engelm., Cunninghamia laceolata (Lamb.) Hook., and Schima superba Gardn. et Champ. in a restored forest ecosystem in the Jiazhu River Basin. Seasonal variation and the relationship between the foliar δ13Cvalues of the four species and environmental factors (monthly total precipitation, monthly average air temperature, relative humidity, atmospheric pressure, and monthly total solar radiation and evaporation)were investigated. The monthly δ13C values and WUE of the four species increased with increasing precipitation, air temperature, solar radiation, and evaporation, whereas δ13C values of the four species decreased with increasing relative humidity and atmospheric pressure. Despite significant differences in δ13C seasonal means for the four species, our results demonstrate a significant convergence in the responses of δ13C values and WUE to seasonal variations in environmental factors among the species investigated and that the δ13C signature for each species gives a strong indication of environmental variables. | Hai-Tao LI Jun XIA Le XIANG Tao LIANG Qi-Jing LIU | 2005 | Journal of Integrative Plant Biology2005，47，12： | 5 |

| 15 | A Bunyavirus-Inducible Ubiquitin Ligase Targets RNA Polymerase IV for Degradation during Viral Pathogenesis in Rice显示文摘The ubiquitin-proteasome system(UPS)is an important post-translational regulatory mechanism that controls many cellular functions in eukaryotes.Here,we show that stable expression of P3 protein encoded by Rice grassy stunt virus(RGSV),a negative-strand RNA virus in the Bunyavirales,causes developmental abnormities similar to the disease symptoms caused by RGSV,such as dwarfing and excess tillering,in transgenic rice plants.We found that both transgenic expression of P3 and RGSV infection induce ubiquitination and UPS-dependent degradation of rice NUCLEAR RNA POLYMERASE D1a(OsNRPD1a),one of two orthologs of the largest subunit of plant-specific RNA polymerase IV(Pol IV),which is required for RNA-directed DNA methylation(RdDM).Furthermore,we identified a P3-inducible U-box type E3 ubiquitin ligase,designated as P3-inducible protein 1(P3IP1),which interacts with OsNRPD1a and mediates its ubiquitination and UPS-dependent degradation in vitro and in vivo.Notably,both knockdown of OsNRPD1 and overexpression of P3IP1 in rice plants induced developmental phenotypes similar to RGSV disease symptomss.Taken together,our findings reveal a novel virulence mechanism whereby plant pathogens target host RNA Pol IV for UPS-dependent degradation to induce disease symptoms.Our study also identified an E3 ubiquitin ligase,which targets the RdDM compotent NRPD1 for UPS-mediated degradation in rice. | Chao Zhang Ying Wei Le Xu Kang-Cheng Wu Liang Yang Chao-Nan Shi Guo-Yi Yang Dong Chen Fei-Fei Yu Qi Xie Shou-Wei Ding Jian-Guo Wu | 2020 | Molecular Plant2020，13，6： | 5 |
| 16 | Geomorphic features of Quaternary glaciation in the Taniantaweng Mountain, on the southeastern Qinghai-Tibet Plateau显示文摘We present geomorphological evidence for multiple glacial fluctuations during the Quaternary in the Taniantaweng Mountain, which is situated at the transition zone of the southeastern Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau. To reconstruct the history of glacial evolution during the Quaternary Glaciation, we present a ~13000 km^2 geomorphologic map(1:440,000) for the Quaternary glaciations, as well as three electron spin resonance(ESR) ages and three optically stimulated luminescence(OSL) ages from the landforms. By integrating these with ages from previous studies, four major glacial advances are identified during marine oxygen isotope stages(MIS) 6, 3, 2 and 1. This glacial chronology is in reasonable agreement with existing glacial chronologies from other parts of the Hengduan Mountains and surrounding mountains. Glaciers had extended to the Yuqu River during the glacial maximum advance(MIS 6), but became successively more restricted from MIS 3 to MIS 1. The glacial distribution show that precipitation brought by the south Asian monsoon might play a primary role in driving glacial advances during the last glacial period in the southeastern Qinghai-Tibet Plateau. | ZHANG Wei CHAI Le IAN S.Evans LIU Liang LI Ya-peng QIAO Jing-ru TANG Qian-yu SUN Bo | 2019 | Journal of Mountain Science2019，16，2： | 5 |
| 17 | Heritability of growth traits in the Asian seabass (Lates calcarifer)显示文摘Growth is an economically important trait in aquaculture.To improve growth trait of the Asian seabass(Lates calcarifer)we have been carrying out,since 2004,a selective breeding program.This study focuses on growth traits in the F2 fish generation,comprised of offspring from 23 mass crosses from 383 F_(1) brooders.Using genotyping analysis for 10 microsatellites from both brood stock and progeny we have reconstructed the pedigree of each mass-cross.For F_(2) generation at 90 days post hatch(dph),we have recorded body weight(BW)for 12,117 individuals and total length(TL),standard length(SL)and condition factor(K_(tl) and K_(sl))for 3530 individuals;and all five traits for 2136 individuals at 270 dph.At 90 dph the average BW was 46.88±20.95 g.Combining pedigree information,recorded growth traits and Restricted Maximum Likelihood method,we have estimated that the narrow sense heritability(h^(2))in F_(1) fish for BW,TL,SL,K_(tl) and K_(sl) was at,90 dph,0.12±0.03,0.11±0.03,0.10±0.03,0.20±0.04 and 0.11±0.03,respectively and,at 270 dph,0.34±0.07,0.32±0.07,0.30±0.06,0.13±0.04 and 0.11±0.04,respectively.At 90 dph the realised heritability for BW was 0.13.Comparing with F_(1) generation,the growth performance of F_(2) fish was increased by 14.4%.Heritability of growth traits will be useful for future genetic improvement programmes of the Asian seabass. | Baoqing Ye Ziyi Wan Le Wang Hongyan Pang Yanfei Wen Huiming Liu Bing Liang Huan Sein Lim Junhui Jiang Genhua Yue | 2017 | Aquaculture and Fisheries2017，2，3： | 4 |
| 18 | Leptin activates the JAK/STAT pathway to promote angiogenesis in RF/6A cells in vitro显示文摘AIM: To investigate the effect of leptin on the angiogenesis of RF/6 A cells(monkey retinal choroidal endothelial cells) in vitro and test the cellular signaling in the mechanism.METHODS: RF/6 A cells were cultured in vitro and randomly divided into four groups: normal control, with leptin at 50, 100, 200 ng/m L for cell counting kit-8(CCK8). RF/6 A cell proliferation and migration were examined by Transwell assays, while RF/6 A cell tube formation by Matrigel assay. JAK2, p-JAK2, STAT3, and p-STAT3 protein expression was measured by Western blotting. Cells were then divided into the following treatment groups: control, 100 ng/m L leptin and AG-490(100 ng/m L leptin+10 μmol/L AG-490) for examinations of RF/6 A cellular behaviour again. Analysis of differences was carried out using one-way ANOVA and least significant difference(LSD).RESULTS: RF/6 A cell proliferation, migration and cell tube formation were promoted significantly by leptin in a dose-dependent manner(P<0.05). Western blotting showed that leptin up-regulated p-JAK2 and p-STAT3 expression levels. Treatment with the JAK/STAT pathway inhibitor, AG-490, decreased leptin-induced p-JAK2 and p-STAT3 expression, and inhibited cell proliferation, migration and cell tube formation induced by leptin(P<0.05). CONCLUSION: Leptin can promote RF/6 A cell angiogenesis in vitro via activation of the JAK2/STAT3 signaling pathway. | Le Zhang Rong Li Bing-Hui Wu Ting-Ting Liang Zhe Liu Wei Ju Yi Wang Yu-Ting Wen Ming-Cui Liu Jun-Hui Du | 2022 | International Journal of Ophthalmology(English edition)2022，15，4： | 4 |
| 19 | Nanoprobes for super-resolution fluorescence imaging at the nanoscale显示文摘Compared with other imaging techniques,fluorescence microscopy has become an essential tool to study cell biology due to its high compatibility with living cells.Owing to the resolution limit set by the diffraction of light,fluorescence microscopy could not resolve the nanostructures in the range of<200 nm.Recently,many techniques have been emerged to overcome the diffraction barrier,providing nanometer spatial resolution.In the course of development,the progress in fluorescent probes has helped to promote the development of the high-resolution fluorescence nanoscopy.Here,we describe the contributions of the fluorescent probes to far-field super resolution imaging,focusing on concepts of the existing super-resolution nanoscopy based on the photophysics of fluorescent nanoprobes,like photoswitching,bleaching and blinking.Fluorescent probe technology is crucial in the design and implementation of super-resolution imaging methods. | HOU ShangGuo LIANG Le DENG SuHui CHEN JianFang HUANG Qing CHENG Ya FAN ChunHai | 2014 | Science China Chemistry2014，57，1： | 4 |
| 20 | Recent understanding on the subgrid-scale modeling of large-eddy simulation in physical space显示文摘In the last 50 years,the methodology of large-eddy simulation(LES)has been greatly developed,while lots of different subgridscale(SGS)models have appeared.However,the understanding of the procedure of SGS modeling is still not clear.The present contribution aims at reviewing the recent SGS models and,more importantly,expressing our recent understanding on the SGS modeling of LES in physical space.Taking the Kolmogorov equation for filtered quantities(KEF)as an example,it is argued that the KEF alone is not enough to be a closure method.Three physical laws are then introduced to complete this closure procedure and are expected to inspire the future researches of SGS modeling. | FANG Le SHAO Liang BERTOGLIO J.-P. | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，12： | 4 |
