| 1 | Surface ozone observations during voyages to the Arctic and Antarctic regions显示文摘Surface ozone concentration and UV-B data between 75° N and 70° S were obtained aboard the Chinese polar scientific vessel 'Xue-long' (Snow-Dragon) during the first voyage to the Arctic and the 16th to the Antarctic in 1999-2000. Analysis of these data presents that variations of the surface ozone concentration have small amplitude during voyages except the mid-latitude in the Northern Hemisphere. As a whole, average surface ozone concentration in the Northern Hemisphere is higher than that in the Southern, and high value occurred when the ship sailed close to the continents. The average diurnal variations of the surface ozone in the Northern Hemisphere are also higher compared to the southern counterparts, and high diurnal variations were found at low latitudes, and relative low level in the polar region. | Longhua Lu Lingen Bian Yanjie Cheng Changgui Lu Jie Tang | 2001 | Chinese Science Bulletin2001，46，23： | 8 |

| 3 | The vertical structure and seasonal changes of atmosphere ozone and temperature at Zhongshan Station over East Antarctica显示文摘The vertical structure of the atmospheric ozone and temperature as well as the seasonal variations is presented by using ozone sounding data at Zhongshan Station over East Antarctica from February, 2008 to February, 2009. The results show that the heights of thermal tropopause and ozone tropopause are mostly the same with yearly mean 7.9 and 7.4 km separately above the station. There is obvious seasonal variation in the pressure and temperature of the tropopause, manifested by the clear one-wave pattern with an opposite phase. As the turning point of the tropopause temperature is visible in autumn and faint in spring and winter, the tropopause height can be better confirmed by utilization of the changes of ozone. Seasonal variation of the tropospheric ozone of vertical distribution is not clear, relative to stratosphere. In the spring, ozone in the low level of stratosphere lost seriously. The minimum partial ozone in 14 km was 1.57 MPa only and the maximum partial ozone occurred in the up level stratosphere. In the rest of the season the ozone increases with height rising in the low level of stratosphere. The evidence shows that ozone lost in spring is closely related with low temperature of polar night and the process of PSC photochemical destruction ozone in the stratosphere. From the vertical characteristics and seasonal variation of ozone and temperature, it is meaningful to understand formation and development of Antarctic ozone deletion. | BIAN LinGen LIN Zhong ZHANG DongQi ZHENG XiangDong LU LongHua | 2012 | Science China Earth Sciences2012，55，2： | 6 |
| 4 | Selective feeding of bay scallop Argopecten irradians on phytoplankton community revealed by HPLC analysis of phytopigments in Bohai Sea, China显示文摘Understanding the feeding selectivity on phytoplankton by shellfi sh is currently a big challenge. In order to investigate the feeding behavior of bay scallop ( Argopecten irradians ) on phytoplankton, we compared its compositions of phytopigments in digestive glands with those in the surrounding seawater, and conducted fi ve consecutive investigations between July and November 2016 in a bay scallop culture area along coast of Qinghuangdao City, northwest of the Bohai Sea, China. Phytopigments in four-size fractionated phytoplankton of seawater (micro-(20-200 μm);nano(L)-[10-20 μm];nano(S)-[2.7-10 μm], and pico-[<2.7 μm]) and digestive glands of A . irradians were examined to investigate the selective feeding of A . irradians . Results show that fucoxanthin and peridinin constituted the major part of taxonomically diagnostic carotenoids (TDCs) in the micro- and nano(L)-phytoplankton in seawater. Compared with total phytoplankton biomass of seawater (TPB, sum of the four sizes), a substantial decrease of fucoxanthin proportion to total DCs in digestive glands was observed while that of peridinin, 19′-butanoyloxyfucoxanthin, alloxanthin and 19′-hexanoyloxy-fucoxanthin showed an obvious increase when those pigments were mainly confi ned to micro-sized phytoplankton (20-200 μm). However, zeaxanthin and prasinoxanthin were mainly confi ned to nano(s)- and pico-phytoplankton, of which the proportions in digestive glands were usually lower in TPB. The contribution of lutein to total DCs in digestive glands (with an average of 7.23%) increased compared with TPB of seawater (with an average of 0.63%) during all fi ve sampling times. | JIANG Tao WANG Longhua ZHANG Fuchong FANG Xiao LU Lin ZHANG Jihong WANG Wei QU Keming CHAI Chao | 2019 | Journal of Oceanology and Limnology2019，37，5： | 4 |
| 5 | An in situ ATR-FTIR study of mixed collectors BHA/DDA adsorption in ilmenite-titanaugite flotation system显示文摘This paper researched the enhanced flotation separation performance of ilmenite and titanaugite using the mixed collector benzhydroxamic acid/dodecylamine(BHA/DDA).The interface assembly mechanism was mainly investigated through in situ attenuated total reflectance Fourier transform infrared(ATRFTIR)spectroscopy combined with the two-dimensional correlation spectroscopy(2D-COS)and X-ray photoelectron spectroscopy(XPS).It has been found that BHA/DDA mixed collectors successfully separate ilmenite from titanaugite at a molar ratio of 8:1.Zeta potential experiments suggested that,in the presence of mixed collector system,the BHA-DDA complex adsorbed on the ilmenite surface via the chemically adsorbed BHA and the electrostatically adsorbed DDA,however,the complex adsorbed on the surface of titanaugite unstably.According to in situ ATR-FTIR combined with 2D-COS and XPS results,the interface assembly mechanism of BHA/DDA is summarized as:the function group of BHA molecules first binds to the metal sites on minerals to form bidentate ligand,then DDA co-adsorbed with BHA on the surface of minerals through hydrogen bonding.DDA may change the adsorption modes of some BHA on the ilmenite surface from four-membered ring to five-membered ring,while the modes on the titanaugite surface is true opposite.Finally,recommended adsorption configurations of the BHA/DDA complex on the two mineral surfaces are proposed. | Liping Luo Houqin Wu Longhua Xu Jinping Meng Jiahui Lu Huan Zhou Xiaomei Huo Lingyun Huang | 2021 | International Journal of Mining Science and Technology2021，31，4： | 4 |

| 9 | Feasibility study of the transient electromagnetic method for chamber blasting misfire detection and recognition显示文摘In this paper,transient electromagnetic method was used to carry out the feasibility study on the detection and recognition of chamber blasting misfire.Firstly,an electromagnetic background field was established in the test;secondly,a benign conductor was preset in the chamber,and then the background field was eliminated after the electromagnetic field was measured;thirdly,the transient electromagnetic field was measured again after blasting;at last,the chamber blasting misfire was detected and recognized by comparing the change of eddy current field of the preset benign conductor before and after blasting.The test results showed that:When the buried depth of aluminum box target was no more than 30 m,transient electromagnetic method can clearly identify the position of the aluminum box;when the buried depth of aluminum box was more than30 m,the buried depth and position of the aluminum box was not sure due to the unknown level of secondary eddy current field generated by aluminum box. | Liu Liansheng Liang Longhua Wu Jiyang Jiao Yongbin Lu Zhexiang | 2014 | Engineering Sciences2014，12，6： | 1 |
| 10 | Temperature variations at the Great Wall and Zhongshan stations显示文摘Surface meteorological observations have been carried out at the Great Wall station (GW) and Zhongshan station (ZS) from 1984 to 2008 and from 1989 to 2008 respectively.The variation in mean air temperature and its trends are derived from the meteorological observation data recorded at both stations.The warming rate of the annual mean temperature at GW is similar to that at Bellingshausen station,which is about 3 km distant.Thus,the warming trend is representative of the King George Island region.The warming rate of ZS is less different from that at Davis station,which is about 100 km from ZS.It can be said that the meteorological data recorded at both stations are representative of the regions of the King George Island and east coast of the Antarctic. | BIAN LinGen MA YongFeng LU ChangGui LU LongHua | 2011 | Chinese Journal of Polar Science2011，22，1： | 1 |
| 11 | Climate change:Impact on the Arctic,Antarctic and Tibetan Plateau显示文摘The Arctic,Antarctic and Tibetan Plateau are very sensitive to global climate change.Hence,it is urgent that we improve our understanding of how they respond to climate change,and how those responses in turn affect both regional and global climate.Against a background of current global warming,the three poles display climate diversities temporarily and spatially,which to different degrees affect the weather and climate over China.Enhanced monitoring of climate change in these three areas,as well as connected work on the responses and feedbacks of the three regions to climate change,will provide necessary support for adaptation and the sustainable development of the Chinese economy. | LU LongHua BIAN LinGen ZHANG ZhengQiu | 2011 | Advances in Polar Science2011，22，2： | 1 |

| 16 | Fluorescence lifetime based distance measurement illustrates conformation changes of PYL10-CL2 upon ABA binding in solution state显示文摘Forster resonance energy transfer(FRET)is a widely used distance measurement method to illustrate protein conformational dynamics.The FRET method relies on the distance between donor and acceptor,as well as the labelling efficiency,the size and the properties of the fluorophores.Here,we labelled a pair of small fluorophores and calculated the energy transferred efficiency through fluorescence lifetime analysis,which can provide more reliable distance measurement than intensity attenuation.The donor fluorophore,7-hydroxycoumarin-4-yl-ethylglycine(HC),was genetically incorporated into specific sites of PYL10,obtaining complete labelling efficiency.The acceptor fluorophore,Alexa488,was labelled through the disulfide bond,whose labelling efficiency was estimated through both absorption peaks and lifetime populations.Fluorescence lifetime and anisotropy analysis showed ABA-induced local conformation changes and dynamics of several HC incorporation sites of PYL10.The lifetime-based FRET distance measurement illustrated the conformation changes of PYL10 with or without ABA application,which is consistent with the previously reported crystal structures. | Peng Zhou Pei Lv Lu Yu Sanling Liu Longhua Zhang Changlin Tian | 2019 | Chinese Chemical Letters2019，30，5： | 0 |
| 17 | Transcriptome Profiling of Barley Cultivar Hua 30 MDEC in Response to Agrobacterium Infection显示文摘Agrobacterium-mediated transformation has been widely used in plants.However,the mechanism in plant cells’response to Agrobacterium infection was very complex.The mechanism of the determinants in host cell remains obscure,especially in barley,which is recalcitrant for Agrobacterium-mediated transformation.In the present study,microspore-derived embryogenic calli(MDEC)from barley elite cultivar were employed as unique subjects to characterize the mechanisms during the Agrobacterium infection process.Hua 30 MDEC can be successfully infected by Agrobacterium.RNA-sequencing at different infection points(0,2,6,12,24 hpi)was performed.The average expressional intensity of the whole genomics increased from 0 to 2 hpi,and then decreased subsequently.More upregulated than downregulated differentially expressed genes(DEGs)were counted at the same time.GO enrichment analysis showed that protein modification was significantly overrepresented in upregulated DEGs.Chromosome-related biological processes,gene expression and cellular metabolic processes were significantly overrepresented in downregulated DEGs.KEGG analysis showed that plant defense responses,phenylpropanoid biosynthesis and biosynthesis of amino acids were significantly enriched across the infection time course.Nine DEGs related to defense responses were identified.All DEGs were upregulated from 2 to 24 hpi.We speculate that these genes are possibly related to Agrobacterium infection.These findings will provide deep insights into the molecular events occurring during the process of Agrobacterium-mediated transformation. | Yingbo Li Ting He Guimei Guo Hongwei Xu Yingjie Zong Shuwei Zhang Ruiju Lu Longhua Zhou Chenghong Liu | 2022 | Phyton-International Journal of Experimental Botany2022，91，6： | 0 |

| 19 | Genome-Wide Identification of Candidate Genes Associated with β-glucan Traits in a Hulled and Hulless Barley (Hordeum vulgare L.) Population显示文摘Barley grain is a valuable source ofβ-glucan,which is an important component of dietary fiber with significant human health benefits.Although the genetic basis ofβ-glucan biosynthesis has been widely studied,a genome-wide association study(GWAS)is still required for a scan of the candidate genes related to the complex quantitative trait based on the high-quality barley reference genome.In this study,a GWAS was conducted using a population composed of 87 barley landraces(39 hulled and 48 hulless,β-glucan from 2.07%to 6.56%)with 191,098 nucleotide polymorphisms(SNPs)markers to cover the chromosomes with the highest density.The population was divided into four sub-populations(POP1~POP4),and theβ-glucan content in POP2 was significantly higher than that in other groups,in which most of the hulless barley landraces are from Qinghai-Tibet Plateau in China.Among seven SNP markers identified by GWAS,two(SNP2 and SNP3)of them showed positive correlation toβ-glucan trait and the remaining five(SNP1,SNP4,SNP5,SNP6 and SNP7)showed the negative relationship.Two candidate genes linked to SNP7,HORVU7Hr1G000320 and HORVU7Hr1G000040,belong to the nucleotide triphosphate hydrolase super-family which is probable to affect the activities ofβ-glucan synthase.Another candidate gene associated with SNP1,HORVU1Hr1G000010,is possibly involved in sugar response.In conclusion,our results provide new insights into the genetic basis ofβ-glucan accumulation in barley grains,and the discovery of new SNP markers distributed in each chromosome and the associated candidate genes will be valuable for the breeding of functional barley varieties with high β-glucan. | Longhua Zhou Ting He Guimei Guo Jing Li Ruiju Lu Yingbo Li Chenghong Liu | 2020 | Phyton-International Journal of Experimental Botany2020，89，4： | 0 |
| 20 | Validation of total ozone data between satellite and ground-based measurements at Zhongshan and Syowa stations in Antarctica显示文摘We present validation between total ozone from satellite and ground-based observations of the Dobson and Brewer spectrometers and ozone radiosonde at Zhongshan and Syowa Antarctic research stations, for September 2004 to March 2009. Results show that mean bias error between Zhongshan (Syowa) and Ozone Monitor Instrument Total Ozone Mapping Spectrometer (OMI-TOMS) data are 0.06%±3.32% ( 0.44%±2.41%); between it and OMI Multi Axis Differential Optical Absorption Spectroscopy (OMI-DOAS) data, the error is 0.34%±4.99% ( 0.22%±4.85%). Mean absolute bias error values of OMI-TOMS data are less than those of OMI-DOAS. This means that total ozone of OMI-TOMS is closer to ground-based observation than that of OMI-DOAS. Comparison between direct observational total ozone of ground-based and integrated ozone from the ozone profile measured by ozone radiosonde shows that ozone amount calculated with the Solar Backscatter Ultraviolet (SBUV) method above balloon burst height is similar to corresponding Microwave Limb Sounder (MLS) data. Therefore, MLS data can be substituted with SBUV data to estimate ozone amount above that level. Mean bias error of the MLS ozone column is 2% compared with the ozonesonde column, with standard deviation within 9.5%. Comparison of different layers from ozone profiler and MLS data indicates that at the 215 hPa layer, the MLS ozone value is high, with relative deviation more than 20%. At the 100 hPa and 68 hPa layers, the MLS ozone value is also high. This deviation is mainly in spring, during Antarctic ozone hole appearance. In this period, at the height of severe ozone loss, relative deviation of MLS ozone values is especially large. | BIAN Lingen LIN Zhong ZHANG Dongqi ZHENG Xiangdong LU Longhua | 2012 | Advances in Polar Science2012，23，4： | 0 |
