| 2 | First six months quality assessment of HY-2A SCAT wind products using in situ measurements显示文摘The first Chinese microwave ocean environment satellite HY-2A,carrying a Ku-band scatteromenter(SCAT),was successfully launched in August 2011.The first quality assessment of HY-2A SCAT wind products is presented through the comparison of the first 6 months operationally released SCAT products with in situ data.The in situ winds from the National Data Buoy Center(NDBC)buoys,R/V Polarstern,Aurora Australis,Roger Revelle and PY30-1 oil platform,were converted to the 10 m equivalent neutral winds.The temporal and spatial differences between the HY-2A SCAT and the in situ observations were limited to less than 5min and 12.5 km.For HY-2A SCAT wind speed products,the comparison and analysis using the NDBC buoys yield a bias of–0.49 m/s,a root mean square error(RMSE)of 1.3 m/s and an increase negative bias with increasing wind speed observation above 3 m/s.Although less accurate of HY-2A SCAT wind direction at low winds,the RMSE of 19.19 with a bias of 0.92 is found for wind speeds higher than 3 m/s.These results are found consistent with those from R/Vs and oil platform comparisons.Moreover,the NDBC buoy comparison results also suggest that the accuracy of HY-2A SCAT winds is consistent over the first half year of 2012.The encouraging assessment results over the first 6 months show that wind products from HY-2A SCAT will be useful for scientific community. | WANG He ZHU Jianhua LIN Mingsen HUANG Xiaoqi ZHAO Yili CHEN Chuntao ZHANG Youguang PENG Hailong | 2013 | Acta Oceanologica Sinica2013,32,11: | 10 |
| 3 | Effects of casein glycomacropeptide supplementation on growth performance,intestinal morphology, intestinal barrier permeability and inflammatory responses in Escherichia coli K88 challenged piglets显示文摘Casein glycomacropeptide(CGMP) is a bioactive peptide derived from milk with multiple functions. This study was aimed at evaluating the effects of CGMP as a potential feed additive on growth performance,intestinal morphology, intestinal barrier permeability and inflammatory responses of Escherichia coli K88(E. coli K88) challenged piglets. Eighteen weaning piglets were randomly assigned to three groups.Control group and K88 challenged group received a basal diet, and CGMP treated group received the basal diet supplemented with 1% of CGMP powder. The trail lasted for 12 days, K88 was orally administered to the piglets of K88 challenged group and CGMP treated group on days 8-10. The results showed that the diet containing 1% CGMP significantly alleviated the decrease in average daily gain(P <0.05),increase in pathogenic bacteria amounts in intestinal contents(P < 0.05), intestinal morphology(P > 0.05) and barrier permeability damage(P < 0.05), and acute inflammatory response(P < 0.05)induced by E. coli K88 infection. In conclusion, CGMP supplementation in the diet protected the weaning piglets against E. coli K88 infection. | Yili Rong Zeqing Lu Haiwen Zhang Lin Zhang Deguang Song Yizhen Wang | 2015 | Animal Nutrition2015,,2: | 7 |
| 4 | The validation of the significant wave height product of HY-2altimeter–primary results显示文摘The HY-2 satellite was successfully launched on 16 August 2011.The HY-2 significant wave height(SWH)is validated by the data from the South China Sea(SCS)field experiment,National Data Buoy Center(NDBC)buoys and Jason-1/2 altimeters,and is corrected using a linear regression with in-situ measurements.Compared with NDBC SWH,the HY-2 SWH show a RMS of 0.36 m,which is similar to Jason-1 and Jason-2 SWH with the RMS of 0.35 m and 0.37 m respectively;the RMS of corrected HY-2 SWH is 0.27 m,similar to 0.27 m and 0.23 m of corrected Jason-1 and Jason-2 SWH.Therefore the accuracy of HY-2 SWH products is close to that of Jason-1/2 SWH,and the linear regression function derived can improve the accuracy of HY-2 SWH products. | CHEN Chuntao ZHU Jianhua LIN Mingsen ZHAO Yili HUANG Xiaoqi WANG He ZHANG Youguang PENG Hailong | 2013 | Acta Oceanologica Sinica2013,32,11: | 7 |
| 5 | Vegetation change in the Mt. Qomolangma Nature Reserve from 1981 to 2001显示文摘Based on the NOAA AVHRR-NDVI data from 1981 to 2001, the digitalized China Vegetation Map (1:1,000,000), DEM, temperature and precipitation data, and field investiga- tion, the spatial patterns and vertical characteristics of natural vegetation changes and their influencing factors in the Mt. Qomolangma Nature Reserve have been studied. The results show that: (1) There is remarkable spatial difference of natural vegetation changes in the Mt. Qomolangma Nature Reserve and stability is the most common status. There are 5.04% of the whole area being seriously degraded, 13.19% slightly degraded, 26.39% slightly im- proved, 0.97% significantly improved and 54.41% keeping stable. The seriously and slightly degraded areas, which mostly lie in the south of the reserve, are along the national bounda- ries. The areas of improved vegetation lie in the north of the reserve and the south side of the Yarlung Zangbo River. The stable areas lie between the improved and degraded areas. Degradation decreases with elevation. (2) Degeneration in the Mt. Qomolangma Nature Re- serve mostly affects shrubs, needle-leaved forests and mixed forests. (3) The temperature change affects the natural vegetation changes spatially while the integration of temperature changes, slopes and aspects affects the natural vegetation change along the altitude gradi- ents. (4) It is the overuse of resources that leads to the vegetation degeneration in some parts of the Mt. Qomolangma Nature Reserve. | ZHANG Wei ZHANG Yili WANG Zhaofeng DING Mingjun YANG Xuchao LIN Xuedong LIU Linshan | 2007 | Journal of Geographical Sciences2007,17,2: | 7 |
| 6 | Assessment of the initial sea surface temperature product of the scanning microwave radiometer aboard on HY-2 satellite显示文摘HY-2 satellite is the first satellite for dynamic environmental parameters measurement of China,which was launched on 16th August 2011.A scanning microwave radiometer(RM)is carried for sea surface temperature(SST),sea surface wind speed,columnar water vapor and columnar cloud liquid water detection.In this paper,the initial SST product of RM was validated with in-situ data of National Data of Buoy Center(NDBC)mooring and Argo buoy.The validation results indicate the accuracy of RM SST is better than 1.7 C.The comparison of RM SST and WindSat SST shows the former is warmer than the latter at high sea surface wind speed and the difference between these SSTs is depend on the sea surface wind speed.Then,the relationship between the errors of RM SST and sea surface wind speed was analyzed using NDBC mooring measurements.Based on the results of assessment and errors analysis,the suggestions of taking account of the affection of sea surface wind speed and using sea surface wind speed and direction derived from the microwave scatteromter aboard on HY-2 for SST product calibration were given for retrieval algorithm improvement. | ZHAO Yili ZHU Jianhua LIN Mingsen CHEN Chuntao HUANG Xiaoqi WANG He ZHANG Youguang PENG Hailong | 2014 | Acta Oceanologica Sinica2014,33,1: | 5 |
| 7 | A preliminary assessment of the sea surface wind speed production of HY-2 scanning microwave radiometer显示文摘A scanning microwave radiometer(RM)was launched on August 16,2011,on board HY-2 satellite.The six-month long global sea surface wind speeds observed by the HY-2 scanning microwave radiometer are preliminarily validated using in-situ measurements and WindSat observations,respectively,from January to June 2012.The wind speed root-mean-square(RMS)difference of the comparisons with in-situ data is1.89 m/s for the measurements of NDBC and 1.72 m/s for the recent four-month data measured by PY30-1oil platform,respectively.On a global scale,the wind speeds of HY-2 RM are compared with the sea surface wind speeds derived from WindSat,the RMS difference of 1.85 m/s for HY-2 RM collocated observations data set is calculated in the same period as above.With analyzing the global map of a mean difference between HY-2 RM and WindSat,it appears that the bias of the sea surface wind speed is obviously higher in the inshore regions.In the open sea,there is a relatively higher positive bias in the mid-latitude regions due to the overestimation of wind speed observations,while the wind speeds are underestimated in the Southern Ocean by HY-2 RM relative to WindSat observations. | HUANG Xiaoqi ZHU Jianhua LIN Mingsen ZHAO Yili WANG He CHEN Chuntao PENG Hailong ZHANG Youguang | 2014 | Acta Oceanologica Sinica2014,33,1: | 4 |

| 9 | Size structure of biomass and primary production of phytoplankton:environmental impact analysis in the Dongsha natural gas hydrate zone, northern South China Sea显示文摘The size-fractionated biomass and primary production of phytoplankton, and the influence of environmental factors on it were studied in the Dongsha natural gas hydrate zone of the northern South China Sea in May 2013.Low nutrient, low chlorophyll a(Chl a) and primary productivity characteristics were found in these waters. The phenomena of subsurface Chl a maximum layers(SCMLs) and primary production maximum layers(SPMLs)were observed in the Dongsha waters. There were significant differences in the size-fractionated biomass and primary production that showed picophytoplankton>nanophytoplankton>microphytoplankton in terms of biomass and degree of contribution to production. Vertical biomass distribution indicated there were considerable differences among different phytoplankton within the euphotic zone(Zeu) in spring. For example,microphytoplankton was distributed evenly in the euphotic layer and nanophytoplankton was mainly distributed in the subsurface or in the middle of the euphotic layer, while picophytoplankton was mainly distributed in the middle or bottom of the euphotic layer. Smaller cell size and larger relative surface area allow picophytoplankton to benefit from nutrient competition and to hold a dominant position in the tropical oligotrophic waters of low latitudes. There was a positive correlation between size-fractionated biomass and temperature with pH and a negative correlation between size-fractionated biomass and silicate with phosphate. There was a positive correlation between size-fractionated primary production and temperature and a negative correlation between size-fractionated biomass and salinity with phosphate. Phosphate was an important factor influencing the size structure of phytoplankton. Meanwhile, irradiation and the euphotic layer were more important in regulating the vertical distribution of size-fractionated phytoplankton in the Dongsha natural gas hydrate zone. | KANG Jianhua LIANG Qianyong WANG Jianjun LIN Yili HE Xuebao XIA Zhen ZHENG Xinqing WANG Yu | 2018 | Acta Oceanologica Sinica2018,37,1: | 1 |

| 11 | Reconstruction and prediction of capillary pressure curve based on Particle Swarm Optimization-Back Propagation Neural Network method显示文摘Capillary pressure curve plays a critical role in the reservoir evaluation.It is essential to reconstruct and predict capillary pressure curve properly.Many traditional capillary pressure correlations have been suggested in the literature.However,their major limitation is mainly applicable to homogenous reservoir,and the larger error will be caused when heterogeneous reservoir is dealt by using these mathematical correlations.This study aims at providing an important method based on Particle Swarm Optimization-Back Propagation Neural Network(PSO-BP neural network)to represent and predict capillary pressure curve for homogenous and heterogeneous reservoir.The combination of PSO algorithm and BP neural network converges quickly,which improves the accuracy and efficiency of simulation.In this paper,core samples from three blocks of the same marine-sand reservoir,whose porosity is between 0.6%and 20.0%and permeability is between 0.1mD and 6117mD,are investigated by PSO-BP neural network method and J-Function method respectively.The reconstruction and prediction results are compared with the results obtained by mercury intrusion method in laboratory.The results show that capillary pressure curves reconstructed and predicted by PSO-BP neural network method are in better agreement with mercury intrusion curves than J-Function method,with 0.1%e5%and 5%e8%relative error respectively,which can totally meet the in-situ requirements.It is also demonstrated that PSO-BP neural network method is more suitable for homogenous and heterogeneous reservoir.©2018 Southwest Petroleum University. | Lijun You Qigui Tan Yili Kang Chengyuan Xu Chong Lin | 2018 | Petroleum2018,4,3: | 1 |
| 12 | Structural formation and evolution mechanisms of fracture plugging zone显示文摘A coupled CFD-DEM method is used to simulate the formation process of fracture plugging zone.A photo-elastic system characterizing mesoscale force chain network developed by our own is used to model the pressure evolution in fracture plugging zone to reveal the evolution mechanism of the structure of fracture plugging zone.A theoretical basis is provided for improving the lost circulation control effect in fractured reservoirs and novel methods are proposed for selecting loss control materials and designing loss control formula.CFD-DEM simulation results show that bridging probability is the key factor determining the formation of fracture plugging zone and fracture plugging efficiency.Critical and absolute bridging concentrations are proposed as the key indexes for loss control formula design.With the increase of absolute bridging concentration,the governing factor of bridging is changed from material grain size to the combination of material grain size and friction force.Results of photo-elastic experiments show that mesoscale force chain network is the intrinsic factor affecting the evolution of pressure exerting on the fracture plugging zone and determines the macroscopic strength of fracture plugging zone.Performance parameters of loss control material affect the force chain network structure and the ratio of stronger force chain,and further impact the stability and strength of fracture plugging zone.Based on the study results,the loss control formula is optimized and new-type loss control material is designed.Laboratory experiments results show that the fracture plugging efficiency and strength is effectively improved. | XU Chengyuan ZHANG Jingyi KANG Yili XU Feng LIN Chong YAN Xiaopeng JING Haoran SHANG Xiangyu | 2021 | Petroleum Exploration and Development2021,48,1: | 0 |
| 13 | Study of monthly variations in primary production and their relationships with environmental factors in the Daya Bay based on a general additive model显示文摘In this study, the horizontal and vertical distribution of primary production(PP) and its monthly variations were described based on field data collected from the Daya Bay in January–December of 2016. The relationships between PP and environmental factors were analyzed using a general additive model(GAM). Significant seasonal differences were observed in the horizontal distribution of PP, while vertical distribution showed a relatively consistent unimodal pattern. The monthly average PP(calculated by carbon) ranged from 48.03 to 390.56 mg/(m^2·h),with an annual average of 182.77 mg/(m^2·h). The highest PP was observed in May and the lowest in November.Additionally, the overall trend in PP was spring>summer>winter>autumn, and spring PP was approximately three times that of autumn PP. GAM analysis revealed that temperature, bottom salinity, phytoplankton, and photosynthetically active radiation(PAR) had no significant relationships with PP, while longitude, depth, surface salinity, chlorophyll a(Chl a) and transparency were significantly correlated with PP. Overall, the results presented herein indicate that monsoonal changes and terrestrial and offshore water systems have crucial effects on environmental factors that are associated with PP changes. | KANG Jianhua HUANG Hao LI Weiwen LIN Yili CHEN Xingqun | 2018 | Acta Oceanologica Sinica2018,37,12: | 0 |
| 14 | Strong Coupling of Magnetism and Lattice Induces Near-Zero Thermal Expansion over Broad Temperature Windows in ErFe10V2−xMox Compounds显示文摘Alloys with low thermal expansion could overcome thermal stress issues under temperature-fluctuated conditions and possess important application prospects,while they are restricted to finite chemical components and temperature windows.In this study,we report a novel class of near-zero thermal expansion(near ZTE)alloys,ErFe_(10)V_(2−x)Mo_(x),over a wide temperature range(120–440 K).Neutron diffraction and magnetic measurements demonstrated that the ErFe_(10)V_(2−x)Mo_(x)compounds exhibited complex ferrimagnetic(FIM)structures below Curie temperature(TC).The near-ZTE behaviors were closely related to the itinerant Fe 3d moments in the collinear FIM states,as well as the geometric[−Fe−Fe−]linkages.Further,X-ray absorption near-edge structure(XANES)spectra revealed that the nonmagnetic substitution changed the electronic valence states of Fe atoms,which,in turn,changed Fe 3d moments and TC,hence,regulating the thermal expansion behaviors.Our work provides an insight into chemical modifications of thermal expansion in magnetic intermetallic compounds. | Wenjie Li Kun Lin Yili Cao Chengyi Yu Chin-Wei Wang Xinzhi Liu Kenichi Kato Yilin Wang Jiaou Wang Qiang Li Jun Chen Jinxia Deng Hongjie Zhang Xianran Xing | 2021 | CCS Chemistry2021,3,3: | 0 |
| 15 | M2 macrophage-derived exosomes promote diabetic fracture healing by acting as an immunomodulator显示文摘Diabetes mellitus is a chronically inflamed disease that predisposes to delayed fracture healing.Macrophages play a key role in the process of fracture healing by undergoing polarization into either M1 or M2 subtypes,which respectively exhibit pro-inflammatory or anti-inflammatory functions.Therefore,modulation of macrophage polarization to the M2 subtype is beneficial for fracture healing.Exosomes perform an important role in improving the osteoimmune microenvironment due to their extremely low immunogenicity and high bioactivity.In this study,we extracted the M2-exosomes and used them to intervene the bone repair in diabetic fractures.The results showed that M2-exosomes significantly modulate the osteoimmune microenvironment by decreasing the proportion of M1 macrophages,thereby accelerating diabetic fracture healing.We further confirmed that M2-exosomes induced the conversion of M1 macrophages into M2 macrophages by stimulating the PI3K/AKT pathway.Our study offers a fresh perspective and a potential therapeutic approach for M2-exosomes to improve diabetic fracture healing. | Yili Wang Qiushui Lin Hao Zhang Sicheng Wang Jin Cui Yan Hu Jinlong Liu Mengmeng Li Kun Zhang Fengjin Zhou Yingying Jing Zhen Geng Jiacan Su | 2023 | Bioactive Materials2023,,10: | 0 |
| 16 | Chemical order-disorder nanodomains in Fe_(3)Pt bulk alloy显示文摘Chemical ordering is a common phenomenon and highly correlated with the properties of solid materials.By means of the redistribution of atoms and chemical bonds,it invokes an effective lattice adjustment and tailors corresponding physical properties.To date,however,directly probing the 3D interfacial interactions of chemical ordering remains a big challenge.In this work,we deciphered the interlaced distribution of nanosized domains with chemical order/disorder in Fe_(3)pt bulk alloy.HAAD F-STEM images evidence the existence of such nanodomains.The reverse Monte Carlo method with the X-ray pair distribution function data reveal the 3D distribution of local structures and the tensile effect in the disordered domains at the single-atomic level.The chemical bonding around the domain boundary changes the bonding feature in the disordered side and reduces the local magnetic moment of Fe atoms.This results in a suppressed negative thermal expansion and extended temperature range in Fe_(3)Pt bulk alloy with nanodomains.Our study demonstrates a local revelation for the chemical order/disorder nanodomains in bulk alloy.The understanding gained from atomic short-range interactions within the domain boundaries provides useful insights with regard to designing new functional compounds. | Qiang Li Yang Ren Qinghua Zhang Lin Gu Qingzhen Huang Hui Wu Jing Sun Yili Cao Kun Lin Xianran Xing | 2022 | National Science Review2022,9,12: | 0 |
