| 1 | Tillage and straw mulching impacts on grain yield and water use efficiency of spring maize in Northern Huang–Huai–Hai Valley显示文摘A two-year field experiment(2012–2013) was conducted to investigate the effects of two tillage methods and five maize straw mulching patterns on the yield, water consumption,and water use efficiency(WUE) of spring maize(Zea mays L.) in the northern Huang–Huai–Hai valley of China. Compared to rotary tillage, subsoil tillage resulted in decreases in water consumption by 6.3–7.8% and increases in maize yield by 644.5–673.9 kg ha-1, soil water content by 2.9–3.0%, and WUE by 12.7–15.2%. Chopped straw mulching led to higher yield,soil water content, and WUE as well as lower water consumption than prostrate whole straw mulching. Mulching with 50% chopped straw had the largest positive effects on maize yield, soil water content, and WUE among the five mulching treatments. Tillage had greater influence on maize yield than straw mulching, whereas straw mulching had greater influence on soil water content, water consumption, and WUE than tillage. These results suggest that 50% chopped straw mulching with subsoil tillage is beneficial in spring maize production aiming at high yield and high WUE in the Huang–Huai–Hai valley. | Zhiqiang Tao Congfeng Li Jingjing Li Zaisong Ding Jie Xu Xuefang Sun Peilu Zhou Ming Zhao | 2015 | The Crop Journal2015，3，5： | 26 |

| 3 | Entransy dissipation minimization for optimization of heat exchanger design显示文摘In this paper,by taking the water-water balanced counterflow heat exchanger as an example,the entransy dissipation theory is applied to optimizing the design of heat exchangers.Under certain conditions,the optimal duct aspect ratio is determined analytically.When the heat transfer area or the duct volume is fixed,analytical expressions of the optimal mass velocity and the minimal entransy dissipation rate are obtained.These results show that to reduce the irreversible dissipation in heat exchangers,the heat exchange area should be enlarged as much as possible,while the mass velocity should be reduced as low as possible. | LI XueFang GUO JiangFeng XU MingTian CHENG Lin | 2011 | Chinese Science Bulletin2011，56，20： | 16 |
| 4 | Maize kernel weight responses to sowing dateassociated variation in weather conditions显示文摘Variation in weather conditions during grain filling has substantial effects on maize kernel weight(KW). The objective of this work was to characterize variation in KW with sowing date-associated weather conditions and examine the relationship between KW, grain filling parameters, and weather factors. Maize was sown on eight sowing dates(SD) at 15–20-day intervals from mid-March to mid-July during 2012 and 2013 in the North China Plain. With sowing date delay, KW increased initially and later declined, and the greatest KW was obtained at SD6 in both years. The increased KW at SD6 was attributed mainly to kernel growth rate(Gmean), and effective grain-filling period(P). Variations in temperature and radiation were the primary factors that influenced KW and grain-filling parameters. When the effective cumulative temperature(AT) and radiation(Ra)during grain filling were 950 °C and 1005.4 MJ m-2, respectively, P and KW were greatest. High temperatures(daily maximum temperature [Tmax] > 30.2 °C) during grain filling under early sowing conditions, or low temperatures(daily minimum temperature [Tmin] < 20.7 °C) under late sowing conditions combined with high diurnal temperature range(Tmax-min> 7.1 °C) decreased kernel growth rate and ultimately final KW. When sowing was performed from May 25 through June 27, higher KW and yield of maize were obtained. We conclude that variations in environmental conditions(temperature and radiation) during grain filling markedly affect growth rate and duration of grain filling and eventually affect kernel weight and yield of maize. | Baoyuan Zhou Yang Yue Xuefang Sun Zaisong Ding Wei Ma Ming Zhao | 2017 | The Crop Journal2017，5，1： | 15 |
| 5 | Genetic Mechanism of Dolomitization in Fengcheng Formation in the Wu-Xia area of Junggar Basin,China显示文摘The dolomitic rocks of the Fengcheng Formation are considered to be formed under special geologic conditions,and are significant hydrocarbon reservoir rocks in the Wu-Xia area in the Junggar Basin.Analyses of petrologic characteristics and stable isotope composition indicate that the dolomitizing host rock is volcanic and the dolomitizing fluids probably consists of brine from shore-shallow lakes with great evaporation and salinity in the Fengcheng Formation,which have formed under arid climatic conditions,as well as residual Mg-rich seawater from the underlying Jiamuhe Formation and Carboniferous.Dust tuff in the area has significant plagioclase content.Anorthite and labradorite hydrolysis by CO2 can be coupled with calcite precipitation.Late Mg-rich brine percolated and replaced calcite formed in the early time,which lead to precipitate dolostones with different occurrences,such as graniphyric,random bedded or lumpy.The diagenetic dolostones with different occurrences resulting from particular formation conditions occurred in different tectonic settings.The dolomitizing fluid has been driven by the thermal convection flow generated by volcanic eruptions.At the same time,the overthrusts of the Wu-Xia growth fault have speeded up the flow of deep Mg-rich water upwards,and induced the water to quickly penetrate and horizontally migrate in the strata.Fracture is the major and the most important reservoir space in dolomitic reservoir of the Fengcheng Formation.Fracture and fault plays a decisive role in controlling the formation of dolostone and the distribution of favorable reservoirs.The deliverability of oil and gas is determined by the development and match relations of dissolved pores and fractures to a certain degree. | ZHU Shifa ZHU Xiaomin NIU Huapeng HAN Xuefang ZHANG Yueqian YOU Xincai | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 12 |
| 6 | Chemical composition, mass closure and sources of atmospheric PM_(10) from industrial sites in Shenzhen, China显示文摘Concentrations of atmospheric PM10 and chemical components (including twenty-one elements, nine ions, organic carbon (OC) and elemental carbon (EC)) were measured at five sites in a heavily industrial region of Shenzhen, China in 2005. Results showed that PM10 concentrations exhibited the highest values at 264 μg/m3 at the site near a harbor with the influence of harbor activities. Sulfur exhibited the highest concentrations (from 2419 to 3995 ng/m3) of all the studied elements, which may be related to the influence of coal used as fuel in this area for industrial plants. This was verified by the high mass percentages of SO42-, which accounted for 34.3%-39.7% of the total ions. NO3-/SO42- ratios varied from 0.64-0.71, which implies coal combustion was predominant compared with vehicle emission. The anion/cation ratios range was close to 0.95, indicating anion deficiency in this region. The harbor site showed the highest OC and EC concentrations, with the influence of emission from vessels. Secondary organic carbon accounted for about 22.6%-38.7% of OC, with the highest percentage occurring at the site adjacent to a coal-fired power plant and wood plant. The mass closure model performed well in this heavily industrial region, with significant correlation obtained between chemically determined and gravimetrically measured PM10 mass. The main constituents of PM10 were found to be organic materials (30.9%-69.5%), followed by secondary inorganic aerosol (7.9%-25.0%), crustal materials (6.7%-13.8%), elemental carbon (3.5%-10.8%), sea salt (2.4%-6.2%) and trace elements (2.0%-4.9%) in this heavily industrialized region. Principal component analysis indicated that the main sources for particulate matter in this industrial region were crustal materials and coal/wood combustion, oil combustion, secondary aerosols, industrial processes and vehicle emission. | Gang Wu Xin Du Xuefang Wu Xiao Fu Shaofei Kong Jianhua Chen Zongshuang Wang Zhipeng Bai | 2013 | Journal of Environmental Sciences2013，25，8： | 11 |
| 7 | Diagenesis and Their Succession of Gas-bearing and Non-gas-bearing Reservoirs in the Sulige Gas Field of Ordos Basin,China显示文摘Comparisons have been made among lithology, diagenesis, and reservoir characteristics of gas-bearing and non-gas-bearing ones in the Sulige gas field of the Ordos Basin based on the laboratory analysis of thin sections, scanning electron microscope, and liquid inclusion of the reservoirs. The reservoirs of the Sulige gas field are now in the middle stage of diagenesis and have undergone compaction, cementation and dissolution. The secondary pore of the reservoir originated from the dissolution of the feldspar and tuff because of the organic acid action from the source rocks during the diagenetic middle stage. Gas-bearing reservoirs are common in soluble pore diagenetic facies of coarse detritus quartzose sandstone, whereas non-gas-bearing ones are common in tense compaction diagenetic facies of mud-bearing medium-fine detritus quartzose sandstone and residual intergranular pore diagenetic facies of mud-bearing medium-coarse detritus quartzose sandstone. The secondary pore is developed in gas-bearing reservoirs of the Sulige gas-field as the medium-coarse grain reservoirs formed in a powerful sedimentary environment and experienced strong dissolution. However, the sediments of fine grain size form the non-gas-bearing reservoirs because of less residual primary pore and secondary pore. | ZHU Xiaomin LIU Chenlin ZHONG Dakang HAN Xuefang | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 9 |
| 8 | Variations in leaf characteristics of three species of angiosperms with changing of altitude in Qilian Mountains and their inland high-altitude pattern显示文摘In this study,39 leaf samples of three angiosperms(Betula albo-sinensis,tree species;and Caragana jubata and Berberis diaphana,shrub species) were collected in the middle-east parts at 2300–3640 m asl of the Qilian Mountains to study the variations of leaf characteristics of angiosperms with altitude change in inland high-altitude regions of China.Five leaf indexes,viz.epidermal cell density(ED),stomatal density(SD),stomatal index(SI),leaf vein density(VD) and carbon isotopic ratio(δ13C),were analyzed in laboratory.The results show that there are significant or even very significant linear correlations between the five indexes and altitude,of which SD,SI and VD exhibit a negative correlation with altitude,while ED and δ13C exhibit a positive correlation with altitude.Such a correlation assemblage is quite different from the situation in the low-altitude humid environment.Generally,only an assemblage of positive correlations can be observed between the indexes(viz.SD,SI and δ13C,etc.) and the altitude in the low-altitude humid environment,which were caused mainly by the plants' responses to the change of atmospheric CO2 concentration(Cα).However,an assemblage of the negative and positive correlations found here may be attributed mainly to the plants' responses to the change of physiological drought caused by change of low temperature,and here it is preliminarily called the inland high-altitude pattern of plant leaf variations. | WANG XueFang LI RuiYun LI XiaoZe MA FuJun SUN BaiNian WU JingYu WANG YouKui | 2014 | Science China Earth Sciences2014，57，4： | 8 |
| 9 | Largest Toothed Pterosaur Skull from the Early Cretaceous Yixian Formation of Western Liaoning, China, with Comments on the Family Boreopteridae显示文摘A new pterosaur Moganopterus zhuiana gen. et sp. nov. is erected based on a complete skull with lower jaws and anterior cervical vertebrae. It is characterized by much elongated upper and lower jaws with at least 62 total, long, curved teeth with sharp tips, a well developed parietal crest extending posterodorsally, forming an angle of 15 degrees with the ventral margin of the skull, the ratio of length to width of cervical vertebrae greater than 5:1. The skull length is 750 mm, and it is the largest toothed pterosaur found so far in the world. Based on this new pterosaur, the Boreopteridae can be divided into two subgroups: Boreopterinae sub-fam. nov. and Moganopterinae sub-fam. nov., which is also confirmed by the phylogenetic analysis. | LU Junchang PU Hanyong XU Li WU Yanhua WEI Xuefang | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 6 |
| 10 | A New Oviraptorid Dinosaur (Theropoda: Oviraptorosauria) from the Late Cretaceous of Jiangxi Province, Southern China显示文摘A new oviraptorid dinosaur Jiangxisaurus ganzhouensis gen. et sp. nov., is erected based on a partial skeleton from the Upper Cretaceous Nanxiong Formation of Ganzhou City, Jiangxi Province. The new taxon differs from other oviraptorids in the weakly downturned rostrum of the lower jaw, much-elongated mandible with a height-to-length ratio being about 20% and the length ratio of radius to humerus of about 0.70. This species not only adds a new member to oviraptorid dinosaurs, but also provides more information about oviraptorid paleogeographical distribution in southern China. | WEI Xuefang PU Hanyong XU Li LIU Di Lü Junchang | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 6 |
| 11 | A New Somphospondylan Sauropod (Dinosauria, Titanosauriformes) from the Late Cretaceous of Ganzhou, Jiangxi Province of Southern China显示文摘A new somphospondylan sauropod (Dinosauria, Titanosauriformes): Gannansaurus sinensis gen. et sp. nov. from the Late Cretaceous Nanxiong Formation of Ganzhou Basin, Jiangxi Province of southern China is erected based on one nearly complete dorsal vertebra and a mid-caudal vertebra. It is characterized by two centroprezygapophyseal lamina fossae; large, square-shaped concavity formed by centroprezygapophyseal lamina and dorsal margin of the centrum; large infraparapophyseal fossa; three openings present within the large lateral concavity, which occupy 65% length of the centrum; the posterior centroparapophyseal lamina (PCPL) and the anterior centroparapophyseal lamina (ACPL) weakly developed; the posterior centrodiapophyseal lamina (PCDL) separated by an infradiapophyseal fossa into two branches dorsally; parapophyseal and diapophyseal laminae cross to form 'K' configuration. It shares some characters with the Early Cretaceous form-Euhelopus, indicating that it is more closely related to Euhelopus rather than to other titanosauriform sauropods. This means Gannansaurus may have a close phylogenetic relationship with Euhelopus. | Lü Junchang YI Laiping ZHONG Hui WEI Xuefang | 2013 | Acta Geologica Sinica(English Edition)2013，87，3： | 5 |

| 13 | Integrated agronomic practice increases maize grain yield and nitrogen use efficiency under various soil fertility conditions显示文摘Crop yield potential can be increased through the use of appropriate agronomic practices. Integrated agronomic practice (IAP) is an effective way to increase maize (Zea mays L.) grain yield and nitrogen use efficiency (NUE);however, the physiological processes associated with gains in yield potential obtained from IAP, particularly the different under various soil fertility conditions, remain poorly understood. An IAP strategy including optimal planting density, split fertilizer application, and subsoiling tillage was evaluated over two growing seasons to determine whether the effects of IAP on maize yield and NUE differ under different levels of soil fertility. Compared to farmers' practices (FP), IAP increased maize grain yield in 2013 and 2014 by 25% and 28%, respectively, in low soil fertility (LSF) fields and by 36% and 37%, respectively, in high soil fertility (HSF) fields. The large yield gap was attributed mainly to greater dry matter (DM) and N accumulation with IAP than with FP owing to increased leaf area index (LAI) and DM accumulation rate, which were promoted by greater soil mineral N content (Nmin) and root length. Post-silking DM and N accumulation were also greater with IAP than with FP under HSF conditions, accounting for 60% and 43%, respectively, of total biomass and N accumulation;however, no significant differences were found for post-silking DM and N accumulation between IAP and FP under LSF conditions. Thus, the increase in grain yield with IAP was greater under HSF than under LSF. Because of greater grain yield and N uptake, IAP significantly increased N partial factor productivity, agronomic N efficiency, N recovery efficiency, and physiological efficiency of applied N compared to FP, particularly in the HSF fields. These results indicate that considerable further increases in yield and NUE can be obtained by increasing effective soil N content and maize root length to promote post-silking N and DM accumulation in maize planted at high plant density, especially in fields with low soil fertility. | Baoyuan Zhou Xuefang Sun Dan Wang Zaisong Ding Congfeng Li Wei Ma Ming Zhao | 2019 | The Crop Journal2019，7，4： | 5 |
| 14 | The Effect of Netting Solidity Ratio and Inclined Angle on the Hydrodynamic Characteristics of Knotless Polyethylene Netting显示文摘Knotless polyethylene(PE) netting has been widely used in aquaculture cages and fishing gears, especially in Japan. In this study, the hydrodynamic coefficient of six knotless PE netting panels with different solidity ratios were assessed in a flume tank under various attack angles of netting from 0?(parallel to flow) to 90?(perpendicular to flow) and current speeds from 40 cm s^(-1) to 130 cm s^(-1). It was found that the drag coefficient was related to Reynolds number, solidity ratio and attack angle of netting. The solidity ratio was positively related with drag coefficient for netting panel perpendicular to flow, whereas when setting the netting panel parallel to the flow the opposite result was obtained. For netting panels placed at an angle to the flow, the lift coefficient reached the maximum at an attack angle of 50? and then decreased as the attack angle further increased. The solidity ratio had a dual influence on drag coefficient of inclined netting panels. Compared to result in the literature, the normal drag coefficient of knotless PE netting measured in this study is larger than that of nylon netting or Dyneema netting. | TANG Hao HU Fuxiang XU Liuxiong DONG Shuchuang ZHOU Cheng WANG Xuefang | 2017 | Journal of Ocean University of China2017，16，5： | 4 |
| 15 | Three Tiaobu Feishen therapies protect human alveolar epithelial cells against cigarette smoking and tumor necrosis factor-mlear factor-kappa B pathwayα-induced inflamation by nuc显示文摘OBJECTIVE: To investigate the efficacy of Tiaobu Feishen formulae(TBFS), including Bufei Jianpi formula(BJF), Bufei Yishen formula(BYF), and Yiqi Zishen formula(YZF), on inflammatory response, protease-anti-protease imbalance and collagen deposition in rats.METHODS: In present work, we used an in vitro model of cigarette smoking extract(CSE)-and tumor necrosis factor-α(TNF-α)-induced A549 cellsto examine the efficacy of BJF, BYF and YZF on the production of inflammatory cytokines, including TNF-α and interleukin(IL)-8, IL-6, matrix metalloproteinases(MMP)-9, and IL-10 in CSE or TNF-ls. And their related transcripα-induced A549 celtion factors and signaling pathway were also analyzed.RESULTS: The results showed that BJF, BYF and YZF could significantly decrease the expression levels of the pro-inflammatory cytokines induced by CSE or TNF-α. Furthermore, BJF, BYF and YZF could suppress CSE-or TNF-α-induced activation of nuclear factor-kappa B(NF-κB) transcription factors and its corresponding pathways. Taken together, these data implied that BJF, BYF and YZF effectively inhibited CSE-or TNF-α-induced inflammatory response in alveolar epithelial cell, which was due to their inhibition effect on NF-κB pathways.CONCLUSION: Our findings suggest that the Tiaobu Feishen therapies may protect human alveolar epithelial cells against cigarette smoking and TNF-α-induced inflammation. NF-κB pathway may involve in the actions. | Chen Yulong Wu Yaosong Li Jiansheng Feng Suxiang Hao Lili Liu Xuefang Zheng Wanchun Dong Haoran Qin Yanqin Yin Sugai Zhao Peng | 2019 | Journal of Traditional Chinese Medicine2019，39，1： | 4 |

| 17 | Recent progress on discovery of novel phosphors for solid state lighting显示文摘Luminescent materials play indispensable roles in many application areas such as lighting,advanced displays,bio-imaging,medical treatments,sensing and detection.Pursuing new luminescent materials with improved or desired properties is an endless mission,driven by increasing demands of advances in technologies and applications.The traditional trial-and-error method,usually based on intensive experiments,cannot search for new materials in a fast and efficient way,therefore alternative model-or theory-based approaches for materials discovery need to be developed.In this work we overviewed several promising methods for screening and discovering novel luminescent materials,including solid state combinatorial chemistry,chemical unit substitution,single particle diagnosis and high-throughput calculations.These methods,having their own merits and demerits,enable to search for new phosphor materials with interesting properties for white light-emitting diodes(wLEDs)rapidly and efficiently.Finally,data-driven discovery of materials is emphasized as a state-of-art approach. | Xuefang Luo Rong-Jun Xie | 2020 | Journal of Rare Earths2020，38，5： | 4 |
| 18 | Comparison of nominal and standardized catch per unit effort data in quantifying habitat suitability of skipjack tuna in the equatorial Pacific Ocean显示文摘In the western and central Pacific Ocean,upper strata waters exhibit highly dynamic oceanographic features under ENSO variability.This has been proved to be responsible for the dynamic change of both abundance and zonal distribution of skipjack tuna(Katsuwonus pelamis).Although causality has been suggested by researchers using physical-biological interaction models,cumulative evidence needs to be obtained and the tenability of assertion needs to be tested from an ecological habitat perspective,based on fisheries data.For purse seine fishery,the use of catch per unit effort(CPUE)as an indication of the abundance is confusing because of technical improvements over the whole exploitation history and unbalanced individual fishing characteristic of vessels.It is particularly interesting to discriminate between habitat characteristics in comparative scenarios of CPUE application.This study identified habitat traits based on a series of oceanographic factors from a global ocean reanalysis model.A comparison was conducted between two habitat models based on unprocessed purse seine CPUE and standardized CPUE considering fishing characteristics.The results suggest that standardized CPUE could model the regular zonal shift of habitat compatible with the observed fishing efforts transfer,and achieved better prediction capacity than unprocessed CPUE.Furthermore,the habitat of skipjack tuna was also characterized and linked with surface and subsurface thermal environment,ocean current,dissolved oxygen,biotic environment,and ENSO variability.The monthly-averaged habitat suitable index,derived from the optimal habitat model prediction,showed a significant linear relationship with the southern oscillation index,which suggested that El Ni?o episodes eventually provide more preferable habitat for skipjack tuna under ENSO variability. | Cheng Zhou Yuanyuan Hu Jie Cao Liuxiong Xu Xuefang Wang Rong Wan Yu Xiao Jiangfeng Zhu Hao Tang | 2022 | Acta Oceanologica Sinica2022，41，3： | 3 |
| 19 | Selenium-enriched oolong tea(Camellia sinensis)extract exerts anti-inflammatory potential via targeting NF-κB and MAPK pathways in macrophages显示文摘Both tea polyphenols and selenium(Se)have been suggested to exert the health benefits via the regulatory capacities of chronic inflammation,which make Se-enriched oolong tea a promising beverage as an anti-inflammatory diet.The aim of this study is to investigate the anti-inflammatory effects of Se-enriched oolong tea extract(Se-TE)and underlying mechanism in lipopolysaccharide(LPS)-induced RAW264.7 cells.Se-TE treatments(50 and 150μg/m L)significantly suppressed the over-production of nitric oxide(NO)and prostaglandin E2(PGE2)in LPS-stimulated macrophages via downregulating the expression of nitric oxide synthase(i NOS)and cyclooxygenase-2(COX-2).Moreover,Se-TEs also effectively inhibited the productions of inflammatory cytokines,such as tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-1β(IL-1β).Furthermore,Se-TE could block mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signaling pathways through the inhibition of the phosphorylation of key proteins(IκB-α,p65,p38,ERK,and JNK)and the translocation of the p65 subunit into the nucleus.Collectively,our results indicated that Se-TE may have the potential to be used as a novel food ingredient for the development of various anti-inflammatory foods and the treatment and prevention of chronic inflammation-related diseases. | Qi Wang Juqing Huang Yafeng Zheng Xuefang Guan Chenchun Lai Huiying Gao Chi-Tang Ho Bin Lin | 2022 | Food Science and Human Wellness2022，11，3： | 3 |
| 20 | Chemical composition of walnuts from three regions in China显示文摘To reveal the characteristic chemicals of walnuts from different origins, we analyzed fatty acid composition,tocopherols, phytosterols and total phenolic content (TPC) of walnuts from three main producing regions inChina. The results showed that walnuts were rich in polyunsaturated fatty acids, and the ratio of ω-6 to ω-3 fattyacids was close to the recommendation of Chinese Nutrition Society. Moreover, walnuts contain high contents oftocopherols (331.20–414.71 mg/kg), phytosterols (97.17–110.35 mg/100 g) and phenols (38.51–48.08 mg GAE/kg). Significant chemical differences exist among walnuts from three production regions. The highest content ofpolyunsaturated fatty acids was found in walnuts from the northern China, the highest content of tocopherols inwalnuts from southwest China, and the highest contents of phytosterol and TPC in walnuts from northwest China.However, there was no significant difference in the tocopherol, phytosterol and TPC content of walnuts betweenthe Northern China and Northwest China. The above results provide important references for manufacturers andconsumers to select suitable walnut scientifically and reasonably. | Min Liu Xueyan Wang Yu Zhang Lin Xu Yan Liu Li Yu Fei Ma Xuefang Wang Zhiyong Gong Liangxiao Zhang Peiwu Li | 2023 | Oil Crop Science2023，8，1： | 2 |
