| 2 | Meiyu in the middle and lower reaches of the Yangtze River since 1736显示文摘'Yu Xue Fen Cun' records during the Qing Dynasty are used to identify the starting and ending dates of Meiyu at the period of 1736―1911. These results, along with the instrumental meteorological records, are used to reconstruct the series of length and precipitation of Meiyu during 1736―2000 over the middle and lower reaches of the Yangtze River. The characteristics of Meiyu are analyzed since 1736. Moreover, the strength of East Asian Summer Monsoon and locations of rainband are discussed, based on the relationship between the length of Meiyu and the Index of East Asian Summer Monsoon. It is found that the starting and ending dates and the length of Meiyu have significant interannual and in-terdecadal variations. Apart from 7―8 years, 20―30 years and 40 years cycles for the lengths of Meiyu, the centennial oscillation is also presented. The length of Meiyu, monsoon rainband movement over eastern China, and the strength of East Asian Summer Monsoon (EASM) have a very good correlation, which can be expressed in the following: during the periods of 1736―1770, 1821―1870 and 1921―1970, the EASM was stronger, and the monsoon rainband was located in North China and South China easily, corresponding to the decreased length of Meiyu. Whereas during the periods of 1771―1820, 1871―1920 and 1971―2000, the EASM was weaker and monsoon rainband usually stopped at the middle and lower reaches of the Yangtze River, corresponding to the increased length of Meiyu. | GE QuanSheng GUO XiFeng ZHENG JingYun HAO ZhiXin | 2008 | Chinese Science Bulletin2008，53，1： | 28 |
| 3 | Model analysis method (MAM) on the effect of the second-order ionospheric delay on GPS positioning solution显示文摘In this paper,we develop an approach to study the effect of second-order ionospheric delay on GPS positioning based on the ionosphere-free combination (abbreviated to Lc) of GPS dual-frequency carrier phase observables,in which the first-order ionospheric delay has been eliminated.GPS data from IGS WUHN tracking station during April 9 23,2003 is used to perform the above approach,and results show that the second-order ionospheric delay in GPS so-called ionosphere-free observables will result in the regular southward shift of GPS positioning solution.Additionally,the influence of the Earth's magnetic field on second-order ionospheric delay over the Wuhan area is discussed,and it indicates that the Earth's magnetic field is one of the main factors why second-order ionospheric delay results in the regular southward shift of GPS positioning solution over Wuhan area. | LIU XiFeng YUAN YunBin HUO XingLiang LI ZiShen LI Wei | 2010 | Chinese Science Bulletin2010，55，15： | 15 |
| 4 | Determination of Taurine in Biological Samples by High-Performance Liquid Chromatography Using 4-Fluoro-7-Nitrobenzofurazan as a Derivatizing Agent显示文摘Objective A highly sensitive and rapid high‐performance liquid chromatography method with pre‐column derivatization with 4‐fluoro‐7‐nitrobenzofurazan was developed for determination of taurine in biological samples,including plasma,brain,and liver.Methods The optimum derivatization reaction temperature was 70℃,and at this temperature the reaction was complete within 3 min.The derivatized taurine was separated using phosphate buffer (0.02 mol/L,pH 6.0):acetonitrile (84:16,v/v) as the mobile phase at a flow rate of 1.0 mL/min,and a column temperature of 25℃.The taurine derivatives were separated within 20 min (tR:14.5 min) and fluorometrically detected at 530 nm with excitation at 470 nm.Results The intra‐ and the inter‐day coefficients of variation for the method were 5.3% and 7.7%,respectively.The calibration curve was linear from 0.1 μmol/L to 30.0 μmol/L with a correlation coefficient of 0.9995.Conclusion This method can be used to determine the taurine contents in plasma,brain,and liver from normal rats and human plasma. | WANG XiFeng CHI DeFeng SU GuanMin LI Lin SHAO LiHua | 2011 | Biomedical and Environmental Sciences2011，24，5： | 13 |
| 5 | The complete nucleotide sequence and its organization of the genome of Barley yellow dwarf virus-GAV显示文摘The complete nucleotide sequence of genomic RNA of BYDV-GAV was determined. It comprised 5685 nucleotides and contained six open reading frames and four un-translated regions. The size and organization of BYDV-GAV genome were similar to those of BYDV PAV-aus. The nucleotide and deduced amino acid sequences of the six ORFs were aligned and compared with those of other luteoviruses. The results showed that there was a high degree of identity between BYDV-GAV and MAV-PS1 in all ORFs except ORF5 and ORF6, which had only 87.4% and 70.2% identities respectively. The reported genomic nucleotide sequence of MAV was shorter than that of BYDV-GAV, but the comparison of the genomic nucleotide sequences for MAV-PS1 and GAV showed 90.4% sequence identity for the same region of the genome. Ac-cording to the level of sequence similarities, BYDV-GAV should be closely related to BYDV-MAV. | JIN Zhibo WANG Xifeng CHANG Shengjun ZHOU Guanghe | 2004 | Science China(Life Sciences)2004，47，2： | 10 |

| 7 | Xa7, a new executor R gene that confers durable and broad-spectrum resistance to bacterial blight disease in rice显示文摘Bacterial blight(BB)is a globally devastating rice disease caused by Xanthomonas oryzae pv.oryzae(Xoo).The use of disease resistance(R)genes in rice breeding is an effective and economical strategy for the control of this disease.Nevertheless,a majority of R genes lack durable resistance for long-term use under global warming conditions.Here,we report the isolation of a novel executor R gene,Xa7,that confers extremely durable,broad-spectrum,and heat-tolerant resistance to Xoo.The expression of Xa7 was induced by incompatible Xoo strains that secreted the transcription activator-like effector(TALE)AvrXa7 or PthXo3,which recognized effector binding elements(EBEs)in the Xa7 promoter.Furthermore,Xa7 induction was faster and stronger under high temperatures.Overexpression of Xa7 or co-transformation of Xa7 with avrXa7 triggered a hypersensitive response in plants.Constitutive expression of Xa7 activated a defense response in the absence of Xoo but inhibited the growth of transgenic rice plants.In addition,analysis of over 3000 rice varieties showed that the Xa7 locuswas found primarily in the indica and aus subgroups.A variation consisting of an 11-bp insertion and a base substitution(G to T)was found in EBEAvrXa7 in the tested varieties,resulting in a loss of Xa7 BB resistance.Through a decade of effort,we have identified an important BB resistance gene and characterized its distinctive interaction with Xoo strains;these findings will greatly facilitate research on the molecular mechanism of Xa7-mediated resistance and promote the use of this valuable gene in breeding. | Xifeng Chen Pengcheng Liu Le Mei Xiaoling He Long Chen Hui Liu Shurong Shen Zhandong Ji Xixi Zheng Yuchen Zhang Zhenyu Gao Dali Zeng Qian Qian Bojun Ma | 2021 | Plant Communications2021，2，3： | 9 |
| 8 | Mn3O4 nanoparticles@reduced graphene oxide composite:An efficient electrocatalyst for artificial N2 fixation to NH3 at ambient conditions显示文摘Currently,industrial-scale NH3 production almost relies on energy-intensive Haber-Bosch process from atmospheric N2 with large amount of CO2 emission,while low-cost and high-efficient catalysts are demanded for the N2 reduction reaction (NRR).In this study,Mn3O4 nanoparticles@reduced graphene oxide (Mn3O4@rGO) composite is reported as an efficient NRR electrocatalyst with excellent selectivity for NH3 formation.In 0.1 M Na2SO4 solution,such catalyst obtains a NH3 yield of 17.4 μg·h^-1·mg^-1cat.and a Faradaic efficiency of 3.52% at-0.85 V vs.reversible hydrogen electrode.Notably,it also shows high electrochemical stability during electrolysis process.Density functional theory (DFT) calculations also demonstrate that the (112) planes of Mn3O4 possess superior NRR activity. | Hong Huang Feng Gong Yuan Wang Huanbo Wang Xiufeng Wu Wenbo Lu Runbo Zhao Hongyu Chen Xifeng Shi Abdullah M.Asiri Tingshuai Li Qian Liu Xuping Sun | 2019 | Nano Research2019，12，5： | 8 |
| 9 | On-line catalytic upgrading of biomass fast pyrolysis products显示文摘Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was employed to achieve fast pyrolysis of biomass and on-line analysis of the pyrolysis vapors. Four biomass materials (poplar wood, fir wood, cotton straw and rice husk) were pyrolyzed to reveal the difference among their products. Moreover, catalytic cracking of the pyrolysis vapors from cotton straw was performed by using five catalysts, including two microporous zeolites (HZSM-5 and HY) and three mesoporous catalysts (ZrO2&TiO2, SBA-15 and Al/SBA-15). The results showed that the distribution of the pyrolytic products from the four materials differed a little from each other, while catalytic cracking could significantly alter the pyrolytic products. Those important primary pyrolytic products such as levoglucosan, hydroxyacetaldehyde and 1-hydroxy-2-propanone were decreased greatly after catalysis. The two microporous zeolites were ef-fective to generate high yields of hydrocarbons, while the three mesoporous materials favored the formation of furan, furfural and other furan compounds, as well as acetic acid. | LU Qiang ZHU XiFeng LI WenZhi ZHANG Ying CHEN DengYu | 2009 | Chinese Science Bulletin2009，54，11： | 8 |
| 10 | Cocrystallization of N-donor type compounds with 5-sulfosalicylic acid:The effect of hydrogen-bonding supramolecular architectures显示文摘Benzotriazole,N,N'-dimethylpiperazine and N-methylpiperazine were applied to crystallize with 5-sulfosalicylic acid(5-H2SSA),affording three new binary molecular cocrystals [(C6H6N3+).(C7H5O6S-)].H2O(1),[(C6H16N22+)1/2.(C7H5O6S-)].H2O(2) and [(C5H14N22+).(C7H5O6S-)2].3H2O(3) under general conditions.Proton-transferring occurs from acid to nitrogen of N-donor compounds in all compounds 1,2 and 3.Analysis of the hydrogen-bonding synthons and their effects on crystal packing were also presented in the context of crystal engineering and host-guest chemistry.In compound 1,1-D infinite chains are extended to a 2-D layered architecture via strong O-H...O hydrogen bonds and then to a 3-D network by N-H...O interactions.Compound 2 and 3 both have the 1-D chain which is formed by O-H...O bonds and weak C-H...O hydrogen bonds.A common intramolecular S(6) [synthon I] ring is formed by the hydroxyl with the carboxyl group in all three compounds. | WANG Lei XU LingYan XUE RuiFeng LU XiFeng CHEN RuiXin TAO XuTang | 2012 | Science China Chemistry2012，55，1： | 8 |
| 11 | Electroplastic Tensile Behavior of 5A90 Al–Li Alloys显示文摘The electroplastic(EP) tensile properties of 5A90 Al–Li alloys compared with thermal tension were investigated.The microstructural variation at different conditions was observed by SEM and TEM.The current density significantly influences the elongation and the flow stress.With increasing current density,wider and deeper dimples on the fracture surfaces and less dislocation density and pile-ups in the EP tension samples were observed compared with roomtemperature and thermal tension,which indicates the plasticity improvement and flow stress reduction.The EP effect(EPE) mainly results from a comprehensive function of Joule heating and pure EPE.Among them,Joule heating effect is perhaps a dominant factor. | Pengchao Song Xifeng Li Wei Ding Jun Chen | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 7 |
| 12 | Establishment of a transgenic mouse model with liver-specific expression of secretory immunoglobulin D显示文摘Mutation of mevalonate kinase(MVK) is thought to account for most cases of hyperimmunoglobulinemia D syndrome(HIDS) with recurrent fever.However,its mechanism and the relationship between elevated serum immunoglobulin D(IgD) and the clinical features of HIDS are unclear.In this study,we generated by fusion PCR a vector to express high levels of chimeric secretory IgD(csIgD) specifically in the liver.We then generated seven founder lines of transgenic mice by co-microinjection,and verified them using genomic PCR and Southern blotting.We detected the expression of csIgD by reverse transcription PCR,quantitative PCR,western blotting,and enzyme-linked immunosorbent assays.We demonstrated that csIgD could be specifically and stably expressed in the liver.We used flow cytometry to show that overexpression of csIgD in the bone marrow and spleen cells had no effect on B cell development.Morphologic and anatomical observation of the transgenic mice revealed skin damage,hepatosplenomegaly,and nephromegaly in some transgenic mice;in these mice,pathological sections showed high levels of cell necrosis and protein-like sediments in the liver,spleen,and kidney.We demonstrated that the genomic insertion sites of the transgenes did not disrupt the MVK gene on mouse chromosome 5.This transgenic mouse will be useful to explore the pathogenesis of HIDS. | WANG Ping WEI ZhiGuo YAN BoWen HUANG Tan GOU KeMian DAI YunPing ZHENG Min WANG MeiLi CHENG XueQian WANG XiFeng XU Chen SUN Yi | 2012 | Science China(Life Sciences)2012，55，3： | 6 |

| 14 | Corrosion properties of bio-oil and its emulsions with diesel显示文摘Bio-oil is a new liquid fuel but very acidic. In this study, bio-oil pyrolyzed from rice husk and two bio-oil/diesel emulsions with bio-oil concentrations of 10 wt% and 30 wt% were prepared. Tests were carried out to determine their corrosion properties to four metals of aluminum, brass, mild steel and stainless steel at different temperatures. Weight loss of the metals immersed in the oil samples was recorded. The chemical states of the elements on metal surface were analyzed by X-ray photoelectron spectroscopy (XPS). The results indicated that mild steel was the least resistant to corrosion, followed by aluminum, while brass exhibited slight weight loss. The weight loss rates would be greatly enhanced at elevated temperatures. Stainless steel was not affected under any conditions. After corrosion, increased organic deposits were formed on aluminum and brass, but not on stainless steel. Mild steel was covered with many loosely attached corrosion materials which were easy to be removed by washing and wiping. Significant metal loss was detected on surface of aluminum and mild steel. Zinc was etched away from brass surface, while metallic copper was oxidized to Cu2O. Increased Cr2O3 and NiO were presented on surface of stainless steel to form a compact passive protection film. The two emulsions were less corrosive than the bio-oil. This was due to the protection effect of diesel. Diesel was the continuous phase in the emulsions and thus could limit the contact area between bio-oil and metals. | LU Qiang ZHANG Jian ZHU XiFeng | 2008 | Chinese Science Bulletin2008，53，23： | 5 |
| 15 | Overview on the Prediction Models for Sheet Metal Forming Failure:Necking and Ductile Fracture显示文摘The formability of the material determines the amount of available deformation before failure and thus is important for the production of various structural components in industries. The workability of materials is commonly evaluated by different forms of failure models during sheet metal forming(SMF) processes. In order to provide a whole picture about the prediction models for SMF failure, necking-related formability and ductile fracture-related formability studies in SMF processes are systematically summarized, the applicability and limitation of each model are highlighted, and the link between forming limit diagram and ductile fracture criterion is pointed out. Conclusions about some critical issues on failure in SMF are made. | Qi Hu Feifei Zhang Xifeng Li Jun Chen | 2018 | Acta Mechanica Solida Sinica2018，31，3： | 5 |
| 16 | Effect of different levels of nitrogen deficiency on switchgrass seedling growth显示文摘Switchgrass(Panicum virgatum L.) is a warm-season rhizomatous perennial grass that can tolerate diverse abiotic stresses while yielding relatively high biomass, and is considered a leading biofuel feedstock for marginal lands. Nitrogen(N) is crucial for the growth and development of switchgrass, and its tolerance to low N supply and high N use efficiency are very important for its production under poor conditions. The large-scale planting of switchgrass on marginal lands could be an effective approach to solving the problem of feedstock supply for biomass energy. This study used a hydroponic experiment to evaluate the effect of N deficiency on switchgrass seedlings. Three N treatments(0, 0.15, and 1.50 mmol L-1Hoagland's solution)and six cultivars were used, three of each ecotype(upland and lowland). The results showed that biomass, leaf area, root surface area, net photosynthesis, and total chlorophyll content significantly decreased under low N treatments compared with those in full strength Hoagland's nutrient solution. However, once established, all plants survived extreme N stress(0 mmol L-1) and, to some extent, were productive. Cultivar Kanlow performed best of the six cultivars under stress. Significant interactions between stress treatment and cultivars showed that breeding for cultivars with high yield and superior performance under N deficiency is warranted. The lowland outperformed the upland ecotypes under stress, suggesting that lowland cultivars may survive and be productive under a wider range of stress conditions.However, given the better adaptability of lowland ecotypes to hydroponic cultivation, further study is needed. | Yi Zhu Xifeng Fan Xincun Hou Juying Wu Tao Wang | 2014 | The Crop Journal2014，2，4： | 4 |
| 17 | Enhancing electrocatalytic N_(2)-to-NH_(3) fixation by suppressing hydrogen evolution with alkylthiols modified Fe_(3)P nanoarrays显示文摘Electrocatalytic N_(2) reduction provides an attractive alternative to Haber-Bosch process for artificial NH_(3) synthesis.The difficulty of suppressing competing proton reduction,however,largely impedes its practical use.Herein,we design a hydrophobic octadecanethiol-modified Fe_(3)P nanoarrays supported on carbon paper(C18@Fe_(3)P/CP)to effectively repel water,concentrate N_(2),and enhance N_(2)-to-NH_(3) conversion.Such catalyst achieves an NH_(3) yield of 1.80×10^(-10) mol s^(-1)·cm^(-2) and a high Faradaic efficiency of 11.22%in 0.1 M Na_(2)SO_(4),outperforming the non-modified Fe_(3)P/CP(2.16×10^(-11) mol s^(-1)·cm^(-2),0.9%)counterpart.Significantly,C18@Fe_(3)P/CP renders steady Nrfixing activlty/selectivity in cycling test and exhibits durability for at least 25 h.First-principles calculations suggest that the surface electronic structure and chemical activity of Fe_(3)P can be well tuned by the thiol modification,which facilitates N_(2) electroreduction activity and catalytic formation of NH_(3). | Tong Xu Jie Liang Yuanyuan Wang Shaoxiong Li Zhaobai Du Tingshuai Li Qian Liu Yonglan Luo Fang Zhang Xifeng Shi Bo Tang Qingquan Kong Abdullah M.Asiri Chun Yang Dongwei Ma Xuping Sun | 2022 | Nano Research2022，15，2： | 4 |
| 18 | Relationship between precipitation and the infiltration depth over the middle and lower reaches of the Yellow River and Yangtze-Huaihe River Valley显示文摘The purpose of the paper is to extract and make the best use of rainfall information contained in the Chinese historical archives of Qing Dynasty, and reconstruct the precipitation series during 1736-1911.The study followed the Yu-Fen-Cun (rainfall infiltration depth) observation method in Qing Dynasty, to conduct soil infiltration experiment under the natural rainfall conditions during 2004-2006.The related parameters, such as precipitation, intensity, initial soil moisture content and infiltration depth have been measured at 10 stations (east of 105°E, 30°-40°N) with representative climatic conditions and soil physical texture in the middle and lower reaches of the Yellow River and Yangtze-Huaihe River Valley.The statistical results indicate that precipitation is the primary infiuencing factor to infiltration depth and is positively correlated with the infiltration depth.Additionally, the efiects of every factor on infiltration depth are significantly difierent between the middle and lower reaches of the Yellow River and Yangtze-Huaihe River Valley.Finally, the relationship equations of precipitation and infiltration depth are established for each site, most of which can pass over 60% of the variance explanations and provide quantitative models to reconstruct the precipitation series using Yu-Fen-Cun records in Qing Dynasty. | Zhixin Hao Jingyun Zheng Quansheng Ge Xifeng Guo | 2008 | Progress in Natural Science:Materials International2008，18，9： | 4 |

| 20 | Identification of a protein associated with circulative transmission of Barley yellow dwarf virus from cereal aphids, Schizaphis graminum and Sitobion avenae显示文摘Using 2-D electrophoresis and virus overlay assay, a 50-kDa protein (P50) exhibiting specific binding to purified virus particles of BYDV-GAV was found in the protein extracts from Schizaphis graminum and Sitobion avenae, two aphid species transmitting BYDV-GAV. P50 in the extracts of S. graminum was isolated by preparation electrophoresis and electro-eluted proteins from the gel slices for antiserum preparation. After feeding the antiserum through membrane, the transmission efficiencies of S. graminum and S. avenae for BYDV-GAV decreased significantly. It was suggested that P50 should be related with transmission pro- cess. Location of P50 was found at the plasma membrane surrounding the accessory salivary gland (ASG) in the head tissues of S. graminum by immunogold-labelling experiment. The ascertainment of the protein associated with virus transmission has a significance influence on further understanding the transmission mechanism and genetic engineering for resistant to vector transmission. | WANG Xifeng & ZHOU Guanghe State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing 100094, China | 2003 | Chinese Science Bulletin2003，48，19： | 4 |
