| 1 | Ammonia emissions from soil under sheep grazing in Inner Mongolian grasslands of China显示文摘Ammonia (NH3) emission and redeposition play a major role in terrestrial nitrogen (N) cycles and can also cause environmental problems, such as changes in biodiversity, soil acidity, and eutrophication. Previous field grazing experiments showed inconsistent (positive, neutral, and negative) NH3 volatilization from soils in response to varying grazing intensities. However, it remains unclear whether, or to what extent, NH3 emissions from soil are affected by increasing grazing intensities in Inner Mongolian grasslands. Using a 5-year grazing experiment, we investigated the relationship between NH3 volatilization from soil and grazing pressure (0.0, 3.0, 6.0, and 9.0 sheep/hm2 ) from June to September of 2009 and 2010 via the vented-chamber method. The results show that soil NH3 volatilization was not significantly different at different grazing intensities in 2009, although it was higher at the highest stocking rate during 2010. There was no significant linear relationship between soil NH3 volatilization rates and soil NH4+-N, but soil NH3 volatilization rates were significantly related to soil water content and air temperature. Grazing intensities had no significant influence on soil NH3 volatilization. Soil NH3 emissions from June to September (grazing period), averaged over all grazing intensities, were 9.6±0.2 and 19.0±0.2 kg N/hm2 in 2009 and 2010, respectively. Moreover, linear equations describing monthly air temperature and precipitation showed a good fit to changes in soil NH3 emissions (r=0.506, P=0.014). Overall, grazing intensities had less influence than that of climatic factors on soil NH3 emissions. Our findings provide new insights into the effects of grazing on NH3 volatilization from soil in Inner Mongolian grasslands, and have important implications for understanding N cycles in grassland ecosystems and for estimating soil NH3 emissions on a regional scale. | YunHai ZHANG NianPeng HE GuangMing ZHANG JianHui HUANG QiBing WANG QingMin PAN XingGuo HAN | 2013 | Journal of Arid Land2013，5，2： | 2 |

| 3 | Morphological and phylogenetic analysis of a new Melosira species and revision of freshwater Melosira in China显示文摘Melosira is one of the most common diatom genera found in freshwater ecosystems.There are many freshwater species of Melosira,of which M.varians is the most common.In our investigation of periphytic diatoms in the Jinsha River,China,a new species,M.capsularum sp.nov,was characterized in combined morphological and molecular approaches.M.varians was also analyzed using molecular data.The new species is similar to M.varians,M.moniliformis,M.nummuloides,and M.lineata in morphology.The cells are capsular and join to filaments by mucilage pads that are secreted on the valve face and united into pairs by their cingula.The valve face is domed and covered with small granules,and the valve mantle edge has a milled appearance.The two strains of M.capsularum are in a single clade obviously away from other Melosira species,as determined in phylogenetic analysis based on nuclear small subunit(SSU)rDNA sequences and the chloroplast-encoded rbc L gene.Thus,the results of morphological comparisons and phylogenetic analysis based on molecular data provide strong evidence that M.capsularum is a new species,thereby increasing the total number of recognized freshwater diatom species in China.In addition,we have systematically reclassified the freshwater Melosira that have been recorded in China. | Lin YANG Pan YU Qingmin YOU Guisheng LI Quanxi WANG | 2022 | Journal of Oceanology and Limnology2022，40，2： | 1 |

| 5 | Reviews on sulphur corrosion phenomenon of the oil-paper insulating system in mineral oil transformer显示文摘The active sulphur compounds in transformer oil would react with copper wires and produce cuprous sulphides,which then attach themselves to the surface of copper wires and insulating paper,thus reducing the electrical performance of oil-paper insulation and causing insulation failure.This article aims to make a comprehensive summary on the field of sulphur corrosion of oil-paper insulation in the mineral oil transformer,including the corrosion mechanism of sulphide on copper sheets,the deterioration mechanism of sul-phide on oil-paper,the factors influencing sulphur corrosion reaction,the method of characterising the degree of sulphur corrosion,the protection technology of sulphur corrosion and the field operation measures for sulphur corrosion.Moreover,four key problems that need to be further solved were sorted out:the synergistic deterioration mechanism of sulphide and its transformation mechanism,the micro-process and forming path of sulphur corrosion reaction,the characteristic parameters and quantitative charac-terisation methods of sulphur corrosion degree,and the effective protection technology of sulphide corrosion.To solve these problems,efforts will be made for deeper understanding of the sulphur corrosion phenomenon and its deterioration mechanism based on theo-retical background,the assessment methods and protection technology,endeavouring to put forward solid theoretical basis and feasible technical means for preventing sulphur corrosion insulation failure. | Haoxi Cong Hao Pan Danyang Qian Haiyu Zhao Qingmin Li | 2021 | High Voltage2021，6，2： | 1 |
| 6 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 7 | Micro‐mechanism study on synergistic degradation of the oil‐paper insulation with dibenzyl disulfide,hexadecyl mercaptan and benzothiophene显示文摘In recent years,there have been many cases of transformer failures caused by corrosive sulfides.At present,research mainly focuses on the single sulfide dibenzyl disulphide,but few research on multiple sulphur or the oil‐paper hybrid insulation.In this study,three typical sulfides dibenzyl disulfide,hexadecyl mercaptan and benzothiophene were selected to form seven sulfide‐oil‐paper models.Then relaxation calculations were carried out,and through molecular dynamics simulation,the synergistic effect of different sulfides on the properties of insulating paper and insulating oil was discussed.Results show that the coexistence of the three sulfides has the most severe weakening on the mechanical properties of cellulose,and it also causes great damage to hydrogen bonds.Hexadecyl mercaptan has a weaker effect on hydrogen bond destruction,but it will greatly aggravate the cellulose chain movement.The viscosity of insulating oil is generally increased by the influence of sulfide.Hexadecyl mercaptan is the main factor affecting the viscosity.Thiophene has little effect on the viscosity,ctive protection technology on sulphur corrosion. | Haoxi Cong Hao Pan Xuefeng Hu Minhao Zhang Qingmin Li | 2021 | High Voltage2021，6，3： | 0 |
| 8 | Lineaperpetua gen.nov.:a new diatom genus in the Thalassiosirales supported by morphology and molecular data显示文摘Based on a combination of morphology and molecular data of ribosomal DNA genes,a new diatom genus Lineaperpetua gen.nov.Yu,You,Kociolek&Wang is described.The features that help define Lineaperpetua at the level of genus include:a tangentially undulated valve face;continuous cribra areolae on the valve interior consisting of pores arranged as strips;single rimoportula located inside the ring of marginal fultoportulae.Additionally,phylogenetic analysis based on nuclear small subunit(SSU)rDNA sequences and nuclear large subunit(LSU)rDNA gene placed the three strains of L.lacustris in a single,monophyletic clade at a considerable sequence distance from the other genera(Thalassiosira,Conticribra,Planktoniella,Shinodiscus,and other genera)belonging to Thalassiosirales.Despite the similarities with some species of Thalassiosira,Conticribra,and Spicaticribra,the suite of features found in Lineaperpetua differentiate it from these other genera.These molecular data and morphological characters suggest an affinity of the new genus to the Thalassiosiraceae. | Pan YU Lin YANG Qingmin YOU John Patrick KOCIOLEK Kangyu WANG Yonghong BI Quanxi WANG | 2024 | Journal of Oceanology and Limnology2024，42，1： | 0 |
| 9 | Leaf Wettability Difference Among Tea Leaf Ages and Analysis Based on Microscopic Surface Features显示文摘The wettability of leaf surface,commonly represented by contact angle(CA),affects various physiological and physical processes.The present study aims to better understand the wettability of tea leaves and elucidate its influence on the energy barrier of the droplet condensation process.The CA values of different leaf ages(young,mature and old)of five famous tea cultivars(Maolu,longjing 43,Huangjinya,Zhongcha 108 and Anji Baicha)were measured via the sessile drop method,and the micro-morphology of two cultivars leaves(Maolu,Zhongcha 108)was investigated by a 3D super depth-of-field digital microscope.Specifically,two radically distinctive types of CA trends were observed,one was the decreased firstly and then increased slightly with the increase of leaf age,while the other stayed constant.The valley depth or maximum height(RZ)of Maolu leaf surface increased with the leaf age while the RZ of Zhongcha 108 leaf remained unchanged by comparing the microscopic features.The Maolu mature leaf CA decline attributed to the young leaf was hydrophilic(θ<90°),and it was considered that surface structures like folds and pits on old leaf played a crucial role in making CA increased.Small deviation in CA can lead to significant error in calculation of the contact angle function of energy barrier in phase change.It will have great significant for simulating and better understanding the formation of frost on tea leaves. | Qingmin Pan Yongzong Lu Liang Xue Yongguang Hu | 2023 | Phyton-International Journal of Experimental Botany2023，92，2： | 0 |
| 10 | An improved multiplicative exponent weighting vertical handoff algorithm for WLAN/WCDMA heterogeneous wireless networks显示文摘An improved MEW(multiplicative exponent weighting)algorithm,SLE-MEW is proposed for vertical handoff decision in heterogeneous wireless networks.It introduces the SINR(signal to interference plus noise ratio)effects,LS(least square)and information entropy method into the algorithm.An attribute matrix is constructed considering the SINR in the source network and the equivalent SINR in the target network,the required bandwidth,the traffic cost and the available bandwidth of participating access networks.Handoff decision meeting multi-attribute QoS(quality of service)requirement is made according to the traffic features.The subjective weight relation of decision elements is determined with LS method.The information entropy method is employed to derive the objective weights of the evaluation criteria,and lead to the comprehensive weight.Finally decision is made using MEW algorithm based on the attribute matrix and weight vector.Four 3GPP(the 3rd generation partnership project)defined traffic classes are considered in performance evaluation.The simulation results have shown that the proposed algorithm can provide satisfactory performance fitting to the characteristics of the traffic. | Liu Shengmei Pan Su Mi Zhengkun Meng Qingmin Xu Minghai | 2012 | Engineering Sciences2012，10，1： | 0 |
