| 1 | Model of water-sediment regulation in Yellow River and its effect显示文摘Water-sediment regulation of the Yellow River is to regulate and control the flow and sediment transport relationship of the lower reaches through reservoirs on the main streams and tributaries to create balance between water and sediment so that sediment transport capacity of the downstream channels can be maximized,shrinking of channels be contained,and medium flood channel be restored and maintained.Many years' research by the Yellow River Conservancy Commission(YRCC) reveals the water and sediment transport relationship that will prevent sedimentation at the downstream river channels.Based on this relationship and coming sediment and water conditions in the Yellow River basin,the YRCC,with maximized use of reservoirs on the main streams and tributaries,has developed three models of water-sediment regulation:single Xiaolangdi Reservoir-dominated regulation,space scale water-sediment match,and mainstream reservoirs joint operation.Ten water-sediment regulations based on these three models have resulted in an average drop of 1.5 m in the main channel of the downstream 800 km river and an increase of carrying capacity from 1800 to 4000 m3/s.Besides,the wetland ecosystems of estuarine delta has also been improved and restored significantly. | LI GuoYing SHENG LianXi | 2011 | Science China(Technological Sciences)2011，54，4： | 18 |
| 2 | Cullin-RING Ubiquitin Ligase Family in Plant Abiotic Stress Pathways显示文摘The ubiquitin-proteasome system is a key mechanism that plants use to generate adaptive responses in coping with various en- vironmental stresses. Cullin-RING (CRL) complexes represent a predominant group of ubiquitin E3 ligases in this system. In this review, we focus on the CRL E3s that have been implicated in abiotic stress signaling pathways in Arabidopsis. By comparing and analyzing these cases, we hope to gain a better understanding on how CRL complexes work under various settings in an attempt to decipher the clues about the regulatory mechanism of CRL E3s. | Liquan Guo Cynthia D.Nezames Lianxi Sheng Xingwang Deng Ning Wei | 2013 | Journal of Integrative Plant Biology2013，55，1： | 9 |
| 3 | miR-145 improves metabolic inflammatory disease through multiple pathways显示文摘Chronic inflammation plays a pivotal role in insulin resistance and type 2 diabetes,yet the mechanisms are not completely understood.Here,we demonstrated that serum LPS levels were significantly higher in newly diagnosed diabetic patients than in normal control.miR-145 level in peripheral blood mononuclear cells decreased in type 2 diabetics.LPS repressed the transcription of miR-143/145 cluster and decreased miR-145 levels.Attenuation of miR-145 activity by anti-miR-145 triggered liver inflammation and increased serum chemokines in C57BL/6 J mice.Conversely,lentivirus-mediated miR-145 overexpression inhibited macrophage infiltration,reduced body weight,and improved glucose metabolism in db/db mice.And miR-145 overexpression markedly reduced plaque size in the aorta in ApoE−/−mice.Both OPG and KLF5 were targets of miR-145.miR-145 repressed cell proliferation and induced apoptosis partially by targeting OPG and KLF5.miR-145 also suppressed NF-κB activation by targeting OPG and KLF5.Our findings provide an association of the environment with the progress of metabolic disorders.Increasing miR-145 may be a new potential therapeutic strategy in preventing and treating metabolic diseases such as type 2 diabetes and atherosclerosis. | Min He Nan Wu Man Cheong Leong Weiwei Zhang Zi Ye Rumei Li Jinyang Huang Zhaoyun Zhang Lianxi Li Xiao Yao Wenbai Zhou Naijia Liu Zhihong Yang Xuehong Dong Yintao Li Lili Chen Qin Li Xuanchun Wang Jie Wen Xiaolong Zhao Bin Lu Yehong Yang Qinghua Wang Renming Hu | 2020 | Journal of Molecular Cell Biology2020，12，2： | 7 |
| 4 | Effect of grain refinement induced by wire and arc additive manufacture (WAAM) on the corrosion behaviors of AZ31 magnesium alloy in NaCl solution显示文摘Additive manufacturing(AM)of Mg alloys has become a promising strategy for producing complex structures,but the corrosion performance of AM Mg components remains unexploited.In this study,wire and arc additive manufacturing(WAAM)was employed to produce single AZ31 layer.The results revealed that the WAAM AZ31 was characterized by significant grain refinement with non-textured crystallographic orientation,similar phase composition and stabilized corrosion performance comparing to the cast AZ31.These varied corrosion behaviors were principally ascribed to the size of grain,where cast AZ31 and WAAM AZ31 were featured by micro galvanic corrosion and intergranular corrosion,respectively. | Jianwei LI Youmin QIU Junjie YANG Yinying SHENG Yanliang YI Xun ZENG Lianxi CHEN Fengliang YIN Jiangzhou SU Tiejun ZHANG Xin TONG Bin GUO | 2023 | Journal of Magnesium and Alloys2023，11，1： | 6 |
| 5 | Curing Reaction Kinetics of Epoxy Resin Using Dicyandiamide Modified by Aromatic Amines显示文摘The curing reaction and reaction mechanism of epoxy resin E-44, for which aromatic amine modified dicyandiamide was used as a curing reagent, were investigated by means of differen-tial scanning calorimetry (DSC). The results showed that the modified dicyandiamide had better curing characteristic than un-modified dicyandiamide for epoxy resin E-44, and the curing reac-tion could be carried out at moderate temperature. Apparent acti-vation energy of the curing reaction was decreased appreciably from 123.829 kJ/mol to 61.550-64.405 kJ/mol, and reaction order was decreased from 0.941 to 0.896-0.900. Curing reaction mecha-nism also was discussed. | CHEN Lianxi TIAN Hua LIU Quanwen Wang Jun | 2007 | Wuhan University Journal of Natural Sciences2007，12，6： | 6 |
| 6 | Impact of technology advances on China's CO_2 emission reduction显示文摘Global warming tends to be the major characteristics of the dramatic global climate change.To deal with these changes,the impact of reducing greenhouse gas(GHG) emission on Chinese future economic and social development has to be assessed.In this paper,a Regional Integrated model of Climate and the Economy(RICE),which is well known and accepted widely,has been used for Chinese economic assessment of climate change after introduction,assimilation and verification.Based on a sensitivity analysis of technical parameters in the RICE model and constrained targets proposed for energy saving and emissions reduction technological advance programs of China from 2000 to 2050,the economic impact of the programs is examined.The results indicate that when technology advances,Chinese CO2 emission,climate loss,and the growth rate of atmospheric CO2 concentration and temperature will all decrease.It is assumed that in 2010,the CO2 emission is 20% lower than in 2005,CO2 emission in 2050 would only double the level in 2000,the accumulative CO2 emission would be decreased by 12.4 GtC,and the atmospheric CO2 concentration and temperature in 2050 would reduce by 35 GtC and 0.04°C respectively from 2000 to 2050.The accumulative climate loss from 2000 to 2050 will drop down by 4.6 billion dollar,which only accounts for 6% of the global total benefits.However,the economic benefit the developed countries will obtain is 10 times that for China under such a technological advance scenario.The decrease of the CO2 emission control rate is 1% in cooperation policy while 4.6% in non-cooperation policy,which would relieve China's burden in the control of CO2 total emission and thereby benefit China in participation of the international cooperation for CO2 emission reduction. | ZHENG YouFei LI HaiTao WU RongJun WANG LianXi | 2010 | Chinese Science Bulletin2010，55，19： | 4 |
| 7 | Measurement and Scaling of Mercury on Soil and Air in a Historical Artisanal Gold Mining Area in Northeastern China显示文摘The Jiapigou gold mine area, located in the upper reaches of the Songhua River, was the first and largest artisanal gold mine once in China, and it used to be prominent in two marking years(1870 and 1974). Jiapigou area had a gold mining history of more than 190 years, which was first opened in 1820. Gold extraction with algamation was applied as the dominant method of excavation from 1940 to 2008, and a total of more than 100 t of gold were extracted from the mine using this method and it was estimated that 100–200 t Hg were released, thus causing severe mercury environmental pollution in the mining area. In the experimental campaigns of this study, in situ air and soil Hg concentrations and air-soil Hg fluxes were measured from April 2009 to December 2011. The results showed that in the study area the total gaseous mercury(TGM) concentration exhibited remarkable spatial and temporal distribution patterns, i.e. the TGM gradually decreased following the increase in distance to gold mining sites in space, and the values in spring, summer and autumn were elevated by 1–2 orders of magnitude in comparison with those in winter. Furthermore, at other sampling sites the total soil mercury(TSM) concentration in spring was higher than that in autumn, except for the contrary laws demonstrated at the Erdaogou mining site. However, in spring and winter the Hg flux between air and soil was under the control of different environmental factors, and the characteristics were clear and distinct. In spring the Hg flux between air and soil was directly under the control of solar irradiation, and the releasing process was predominant with a remarkable positive correlation to solar irradiation. Nevertheless, in winter the Hg fluxes were indirectly under the control of solar irradiation, which caused thermal inversion due to the thick snow cover. The depositing process was predominant and the correlations between Hg flux and air temperature was remarkably negative, and there was a positive correlation between Hg flux and solar irradiation. | WANG Zhaojun ZHANG Gang CHEN Xiaobing ZHAO Qiaojing WANG Weiying SHENG Lianxi BIAN Hongfeng LI Zhenxin WANG Deli | 2019 | Chinese Geographical Science2019，29，2： | 3 |
| 8 | Impact of Wetland Change on Local Climate in Semi-arid Zone of Northeast China显示文摘Wetlands are sensitive to climate change, in the same time, wetlands can influence climate. This study analyzed the spatio-temporal characteristics of wetland change in the semi-arid zone of Northeast China from 1985 to 2010, and investigated the impact of large area of wetland change on local climate. Results showed that the total area of wetlands was on a rise in the study area. Although natural wetlands(marshes, riparians and lakes) decreased, constructed wetlands(rice fields) increased significantly, and the highest increase rate in many places exceeded 30%. Anthropogenic activities are major driving factors for wetland change. Wetland change produced an impact on local climate, mainly on maximum temperature and precipitation during the period of May–September. The increase(or decrease) of wetland area could reduce(or increase) the increment of maximum temperature and the decrement of precipitation. The changes in both maximum temperature and precipitation corresponded with wetland change in spatial distribution. Wetland change played a more important role in moderating local climate compared to the contribution of woodland and grassland changes in the study area. Cold-humid effect of wetlands was main way to moderating local climate as well as alleviating climatic warming and drying in the study area, and heterogeneity of underlying surface broadened the cold-humid effect of wetlands. | LIU Yan SHENG Lianxi LIU Jiping | 2015 | Chinese Geographical Science2015，25，3： | 3 |
| 9 | Foraging areas of Rousettus leschenaulti on the Hainan Island of China显示文摘We investigated the foraging area of three individuals (1 female and 2 males) of Rousettus leschenaulti (Chiroptera,Pteropodidae) in suburban Haikou City, Hainan Province, South China from November 2005 to January 2006 using radio telemetry.These animals left the daytime roosting sites about 90 min after sunset with no significant difference in departure time betweenthe male and female bats. The average active times were 391.8 min for males and 533.7 min for the female, respectively.By reconstructing 93 radio-telemetry recording positions, we found that the long axis of foraging area of the bats ranged from7.45 to 11.70 km. The foraging area of the female (3867 ha) was larger than that of the males (1138 ha), and there was overlapbetween the foraging areas of different individuals. These bats usually kept the same flight routes across a few successive daysfrom the daytime roosting site to the foraging areas. Our findings suggested that female R. leschenaulti may explore a larger foragingarea than males. No obvious territorial behaviors were observed in our studied area. | Zhanhui TANG Zhong CHEN Jie MA Guangjian ZHU Xunfeng MA Lianxi SHENG Yuchun LI | 2010 | Current Zoology2010，56，4： | 2 |
| 10 | Large-scale multirole Zn(Ⅱ) programmed synthesis of ultrathin hierarchically porous carbon nanosheets显示文摘ZIF-derived carbon structures are considered as desired electrode materials for supercapacitors due to their high surface area,high conductivity, and porous structure. However, the most reported ratio of 2-methylimidazole and Zn(II) is 4:1 to 20:1, which limits commercial applications due to the increasing cost. In this paper, a multirole Zn(II)-assisted method is presented from Zn(II) solution, Zn O, Zn O/ZIF-8 core-shell nanostructure, to 3 D hierarchical micro-meso-macroporous carbon structures with a1:1 ratio of 2-methylimidazole and Zn(II). The hierarchically porous carbon has a high surface area of 1800 m2 g^(-1) due to the synergistic effect of multirole Zn(II). The unique carbon-based half-cell delivers the specific capacitances of 377 and 221 F g^(-1) at the current densities of 1.0 and 50 A g^(-1), respectively. As a 2.5 V symmetrical supercapacitor, the device reveals a high doublelayer capacitance of 24.4 F g^(-1), a power density of 62.5 k W kg^(-1), and more than 85.8% capacitance can be retained over 10000 cycles at 10 A g^(-1). More importantly, the low-cost hierarchically porous carbon could be easily produced on a large scale and almost all chemicals can be reused in the sustainable method. | XU LingSong MENG FanCheng WEI XiangFeng LIN ChangHao ZHENG LianXi LIU JicHua | 2020 | Science China(Technological Sciences)2020，63，9： | 2 |
| 11 | Echolocation calls of Myotis frater (Chiroptera: Hipposi- deridae) during search flight显示文摘Echolocation calls of Myotis frater emitted during the search phase consist of brief frequency-modulated pulses. The sound signals are comprised of three harmonics of which the first one is of the highest intensity and occurs in all echolocation calls. The frequency of this fundamental harmonic ranges from 110.8 to 50.2 kHz, and its duration is about 3.5 ms. The second and the third harmonics are relatively weak, occurring in 50.0% and 25.0% of echolocation calls respectively, with frequencies ranging from 138.4 to 116.6 kHz for the second harmonic and from 193.6 to 170.8 kHz for the third harmonic. We presume that, according to the echolocation call features, Myotis frater probably forages the insects on the ground of complex environments. | ZHANG Shuyi ZHAO Huihua FENG Jiang SHENG Lianxi LI Zhenxin WANG Lixin | 2000 | Chinese Science Bulletin2000，45，18： | 2 |

| 17 | Relationship between echolocation frequency and body size in two species of hipposiderid bats显示文摘Frequencies of echolocation calls with maximum power of Himalayan leaf-nosed bats and Horsfield’s leaf-nosed bats during searching phase were 74.1 and 92.1 kHz, respectively. Head-body length, forearm length and body mass of Himalayan leaf-nosed bats were 82.9 mm, 89.7 mm and 59.1 g, respectively; and the corresponding values of Horsfield’s leaf-nosed bats were 68.4 mm, 61.3 mm and 19.7 g, respectively. Echolocation frequency and the three parameters of body size, head-body length, forearm length and body mass, were all negatively correlated, and the correlation coefficients were -0.86, -1.58 and -2.19, respectively. This study thereby proved that echolocation frequency and body size were negatively correlated in the two species of hipposiderid bats. | ZHANG Shuyi ZHAO Huihua FENG Jiang SHENG Lianxi WANG Hui WANG Lixin | 2000 | Chinese Science Bulletin2000，45，17： | 1 |
