| 2 | Millennial-centennial Scales Climate Changes of Holocene Indicated by Magnetic Susceptibility of High-resolution Section in Salawusu River Valley, China显示文摘The upmost segment (Holocene series) of the Milanggouwan stratigraphic section (MGS1) in the Salawusu River valley shows 11 sedimentary cycles of dune sands and fluvio-lacustrine facies, or dune sands and paleosols. The analysis of the magnetic susceptibility of this segment suggests that there are 11 magnetic susceptibility cycles with the value alternating from low to high, in which the layers of the dune sands correspond to the lower value of the magnetic susceptibility and the layers of fluvio-lacustrine facies and paleosols correspond to the higher peaks. The study reveals that the low and high magnetic susceptibility values indicate the climate dominated by cold-arid winter monsoon and warm-humid summer monsoon of East Asia, respectively, and the study area has experienced at least 22 times of millennial-centennial scales climate alternation from the cold-arid to the warm-humid during the Holocene. In terms of the time and the climate nature, the variations basically correspond to those of the North Atlantic and some records of cold-warm changes in China as well. They might be caused by the alternation of winter and summer monsoons in the Mu Us Desert induced by global climate fluctuations in the Holocene. | LU Yingxia LI Baosheng WEN Xiaohao QIU Shifan WANG Fengnian NIU Dongfeng LI Zhiwen | 2010 | Chinese Geographical Science2010,20,3: | 19 |

| 4 | Impact of anthropogenic drivers on subaqueous topographical change in the Datong to Xuliujing reach of the Yangtze River显示文摘Changes of subaqueous topography in shallow offshore water pose safety risks for embankments,navigation,and ports.This study conducted measurements of subaqueous topography between Datong and Xuliujing in the Yangtze River using a Sea Bat 7125 multi-beam echo sounder,and the channel change from 1998 to 2013 was calculated using historical bathymetry data.The study revealed several important results:(1)the overall pattern of changes through the studied stretch of the river was erosion–deposition–erosion.Erosion with a volume 700×10~6m^3occurred in the upper reach,deposition of about 204×10~6m^3occurred in the middle reach,and erosion of about 602×10~6m^3occurred in the lower reach.(2)Dunes are the most common microtopographic feature,accounting for 64.3%of the Datong to Xuliujing reach,followed by erosional topography and flat river topography,accounting for 27.6%and 6.6%,respectively.(3)Human activities have a direct impact on the development of the microtopography.For instance,the mining of sand formed holes on the surface of dunes with lengths of 20–35 m and depths of 3–5 m.We concluded that the overall trend of erosion(net erosion volume of 468×10~6m^3)occurred in the study area mainly because of the decreased sediment discharge following the closure of the Three Gorges Dam.However,other human activities were also impact factors of topographic change.Use of embankments and channel management reduced channel width,restricted river meandering,and exacerbated the erosion phenomenon. | Shuwei ZHENG Heqin CHENG Shengyu SHI Wei XU Quanping ZHOU Yuehua JIANG Fengnian ZHOU Minxiong CAO | 2018 | Science China Earth Sciences2018,61,7: | 10 |
| 5 | Relationship between coal size reduction and energy input in Hardgrove mill显示文摘Hardgrove grindability index (HGI) is an important indicator of coal grindability, and is one of the most important parameters to determine the capacity of coal pulverizer in power station. However, HGI is an empirical grindability index without linkages to any known physical parameters. To investigate the effect of energy input on the grinding in Hardgrove mill, a T20WN torque meter was installed on the shaft of a modified Hardgrove mill to record the torque driving the mill. Samples from four kinds of coals with HGI ranging from 36 to 72 were prepared according to the procedure of standard HGI test and ground in a modified Hardgrove mill at different revolutions. The relation of sample size reduction degree to specific comminution energy (E cs ) was studied with Shi-Kojovic model. The results show that Shi-Kojovic model predicted well the coal size reduction degree with E cs in Hardgrove mill. The grindability index given by Shi-Kojovic model has a similar trend with HGI. The relation of sample size reduction degree to E cs reveals that HGI has a non-linear relationship with effective specific energy in Hardgrove mill, which explains the non-linear relation of HGI to industrial pulverizer capacity. | Zuo Weiran Zhao Yuemin He Yaqun Shi Fengnian Duan Chenlong | 2012 | International Journal of Mining Science and Technology2012,22,1: | 8 |
| 6 | Pleniglacial millennium-scale climate variations in northern China based on records from the Salawusu River Valley显示文摘Situated in the Salawusu River Valley, southeast of China's Mu Us Desert, the MGS2 (Milanggouwan section) portion of the Milanggouwan stratigraphic section records 5.5 sedimentary cycles consisting of alternations between dune sand deposits and fluvial or lacustrine facies. We analyzed the grain-size and CaCO 3 distributions in MGS2, and found that Mz (mean particle diameter) and σ (standard deviation) displayed clear variations in peaks and valleys within different sedimentary facies. The CaCO 3 content averaged 0.4% in the dune sand deposits, 1.43% in the fluvial facies, and 8.82% in the lacustrine facies. Both the grain-size distribution and CaCO 3 contents, which equal the indicators for the alternation among the sedimentary facies, suggest the occurrence of 5.5 cycles. These results suggest that the observed cycles mainly resulted from fluctuations between a cold and dry winter monsoon climate and a warm and humid summer monsoon climate, and that the MGS2 portion experienced at least 5.5 fluctuations between these two extremes. This high-frequency climatic fluctuation indicates a strong influence of millennium-scale variations in the strength of the East Asian winter and summer monsoons in our study area during the Pleniglacial. | FengNian WANG BaoSheng LI JiangLong WANG XiaoHao WEN DongFeng NIU ZhiWen LI YueJun SI YiHua GUO ShuHuan DU | 2012 | Journal of Arid Land2012,4,3: | 7 |
| 7 | Breakage and separation mechanism of ZGM coal mill based on parameters optimization model显示文摘Sampling ports were firstly drilled on a ZGM95 coal mill in the power plant in China, and the coal samples from various points in the pulverizer were collected under the different operation conditions. The property of the sampling material from the mill was analyzed, applying the float–sink test, size distribution analysis, proximate analysis and so on. It was indicated that the +250 lm fraction in the pulverized fuel accounted for only 0.02%, while it was 83.2% in the new feed. The circulating ratio and coal flow in the separator and the cone zone were calculated using the mass balance of the circulating load. So, the circulating ratio in the separator of the pulverizer was between 8 and 13, and the circulating ratio, the feed flow of separator and cone zone all raised with the increase of the air volume. Furthermore, the parameters of the separation functions were obtained based on the fitting method. It was shown that the mean value of the shape factor B was 0.7617, and the parameter D which is the particle size at 50% cumulative yield in the separator almost kept unchanged. | Wei Hua He Yaqun Shi Fengnian Zhou Nianxing Wang Shuai Ge Linhan | 2014 | International Journal of Mining Science and Technology2014,24,2: | 5 |
| 8 | Inactive Al^(3+)-doped La(CoCrFeMnNiAl_(x))_(1/(5+x))O_(3)high-entropy perovskite oxides as high performance supercapacitor electrodes显示文摘A series of high-entropy perovskite oxides(HEPOs)La(CoCrFeMnNiAl_(x))_(1/(5+x))O_(3-δ)(x=0.4,0.5,0.6,and 0.7)have been synthesized by coprecipitation method combined with calcination process and explored as electrodes for supercapacitors.The crystal structure,microstructure,and elemental composition of HEPOs were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),and energy-dispersive X-ray spectroscopy(EDS)in detail.The electrochemical properties of HEPOs as supercapacitor electrodes were elucidated.The specific capacitances of HEPOs(x=0.4,0.5,0.6,and 0.7)are 281.84,353.65,325.60,and 259.30 F/g at the current density of 1 A/g,respectively.After 2000 cycles,the specific capacitances of HEPOs(x=0.4,0.5,0.6,and 0.7)remain 85.01%,88.61%,86.37%,and 91.25%,respectively.Such outstanding electrochemical properties can be attributed to the entropy-stabilized structure caused by mixed six cations in B-site and the Al^(3+)-doping suppressing active ion aggregation during charge-discharge process.This research highlights the potential of HEPOs as electrodes for supercapacitors. | Meng GUO Yufeng LIU Fengnian ZHANG Fuhao CHENG Chufei CHENG Yang MIAO Feng GAO Jun YU | 2022 | Journal of Advanced Ceramics2022,11,5: | 2 |
| 9 | Grain-size Characteristics and Climate Variability in TMS5e Sequence of Tumen Section in Southern Tengger Desert,Northwestern China显示文摘The TMS5e sequence from the Tumen section,at the southern edge of Tengger Desert in the northwestern China,is synchronous with Marine Isotope Stage 5e(MIS5e).It consists of 16 layers of aeolian dune sands,11 layers of lacustrine loess-like facies,and 5 layers of lacustrine facies.The results of grain-size analysis shows that the palaeo-mobile dune sands,palaeo-fixed to semi-fixed dune sands and loess-like sandy loams are mainly composed of sands,ranging from 70% to 96%;their silt contents ranged from 4% to 20%,and their clay contents ranged from 1% to 5%;the climate under which the aeolian dune sands were deposited is similar to that under which modern mobile dune sands form,which is caused by the dominance of the cold,dry East Asian winter monsoon.In contrast,the lacustrine loess-like facies and lacustrine facies had a lower sand contents than those of the three aeolian dune sands,but have higher silt and clay contents,most of their sand content ranged from 30% to 60%,their silt contents ranged from 35% to 55%,and their clay contents ranged from 6% to 20%.The lacustrine loess-like facies and lacustrine facies formed under the influence of the warm,humid East Asian summer monsoon based on their similarity with modern sediments.The grain-size indicator Mz(mean grain diameter) and the SC/D value in the TMS5e sequence indicate climatic insta-bility at the southern edge of the Tengger Desert during MIS5e,with at least 14 fluctuations between a warm,humid climate and a cold,dry climate,divided into five stages:TMS5e5(139 kyr to 129.3 kyr B.P.),TMS5e4(129.3 kyr to 124 kyr B.P.),TMS5e3(124 kyr to 119.5 kyr B.P.),TMS5e2(119.5 kyr to 116.5 kyr B.P.),and TMS5e1(116.5 kyr to 113.7 kyr B.P.).These correspond roughly to MIS5e5,MIS5e4,MIS5e3,MIS5e2,and MIS5e1,respectively,in the GRIP ice core data. | WEN Xiaohao LI Baosheng WANG Fengnian ZHENG Yanming NIU Dongfeng SI Yuejin OU Xianjiao | 2012 | Chinese Geographical Science2012,22,1: | 2 |
| 10 | Preparation and electrical conductivity of(Zr,Hf,Pr,Y,La)O high entropy fluorite oxides显示文摘A series of compositionally complex fluorite oxides(CCFOs)were prepared by ball milling the mixture of ZrO_(2),HfO_(2),Y_(2)O_(3),La_(2)O_(3),and Pr_(6)O_(11)followed by conventional solid-state sintering.Both XRD and TG-DSC results demonstrated that single-phase(Zr_(0.2)Hf_(0.2)Pr_(0.2)Y_(0.2)La_(0.2))O_(2-)δwas formed at 1400°C.Elements in bulk ceramic were uniformly distributed without evident accumulation according to SEM-EDS pictures.TEM results revealed that polycrystalline ceramic powder was assignable to cubic Fm-3m fluorite structure.The electrical conductivity(σ)was measured via EIS technology and activation energy(E_(a))of CCFOs was calculated in Arrhenius plots.In the temperature range of 300-750°C,CCFOs preserved the same conduction mechanism and(Zr_(0.1667)Hf_(0.1667)Pr_(0.1667)Y_(0.25)La_(0.25))O_(2-)δpossessed higherσand lower E_(a) than other high entropy fluorite oxides which is related to the incorporation of Pr element or the connection of cation-V_(o) complex. | Fengnian Zhang Fuhao Cheng Chufei Cheng Meng Guo Yufeng Liu Yang Miao Feng Gao Xiaomin Wang | 2022 | Journal of Materials Science & Technology2022,,10: | 2 |
