| 3 | Dual origins of Xiaoqinling gold-bearing quartz veins:Fluid inclusion evidence显示文摘Fluid inclusion research in Archean metamorphic rocks, Yanshanian granite and gold-bearing quartz veins shows that regional metamorphic fluids are high temperature and high saline, Yanshanian post-granitic fluids are CO2-bearing low saline, and ore-forming fluids are also CO2-rich low saline. In gold-barren/free parts of quartz veins in gold deposits, daughter mineral-bearing high saline inclusions related with metamorphic fluids remained. This proclaims quartz veins hosting gold ores might have been formed in early metamorphism, and overlapped or mineralized by late Yanshanian gold-bearing fluids. | Hongrui Fan Yihan Xie Rui Zhao Yinglan Wang | 2000 | Chinese Science Bulletin2000，45，15： | 17 |
| 4 | Zircon U-Pb dating of basement gneisses in the super-large Bayan Obo REE-Fe-Nb deposit, Inner Mongolia显示文摘Zircon U-Pb ages have been determined for basement gneisses in the Bayan Obo REE-Fe-Nb deposit. On the U-Pb concordia diagram data of three samples yield up-per intercept ages of 1948-1917 Ma. Thus, these basement gneisses are of Paleoproterozoic. Rock association of these basement gneisses includes tonalite, syenite and paragneiss, not belonging to a sedimentary package. It is more appro-priate to consider this association as a basement complex rather than a stratigraphic 'Group'. | WANG Kaiyi FAN Hongrui XIE Yihan LI Huimin | 2002 | Chinese Science Bulletin2002，47，3： | 16 |
| 5 | Characteristics of the crystalline basement beneath the Ordos Basin:Constraint from aeromagnetic data显示文摘Aeromagnetic anomaly zonation of the Ordos Basin and adjacent areas was obtained by processing highprecision and large-scale aeromagnetic anomalies with an approach of reduction to the pole upward continuation.Comparative study on aeromagnetic and seismic tomography suggests that aeromagnetic anomalies in this area are influenced by both the magnetic property of the rock and the burial depth of the Precambrian crystalline basement.Basement depth might be the fundamental control factor for aeromagnetic anomalies because the positive and negative anomalies on the reduction to the poleupward-continuation anomaly maps roughly coincide with the uplifts and depressions of the crystalline basement in the basin.The results,together with the latest understanding of basement faults,SHRIMP U-Pb zircon dating of metamorphic rock and granite,drilling data,detrital zircon ages,and gravity data interpretation,suggest that the Ordos block is not an entirety of Archean. | Zhentao Wang Hongrui Zhou Xunlian Wang Xiuchun Jing | 2015 | Geoscience Frontiers2015，6，3： | 15 |

| 7 | Information flow and controlling in regularization inversion of quantitative remote sensing显示文摘In order to minimize uncertainty of the inversed parameters to the largest extent by making full use of the limited information in remote sensing data, it is necessary to understand what the information flow in quantitative remote sensing model inversion is, thus control the information flow. Aiming at this, the paper takes the linear kernel-driven model inversion as an example. At first, the information flow in different inversion methods is calculated and analyzed, then the effect of information flow controlled by multi-stage inversion strategy is studied, finally, an information matrix based on USM is defined to control information flow in inversion. It shows that using Shannon entropy decrease of the inversed parameters can express information flow more properly. Changing the weight of a priori knowledge in inversion or fixing parameters and partitioning datasets in multi-stage inversion strategy can control information flow. In regularization inversion of remote sensing, information matrix based on USM may be a better tool for quantitatively controlling information flow. | YANG Hua, XU Wangli, ZHAO Hongrui, CHEN Xue & WANG Jindi Research Center for Remote Sensing and GIS, School of Geography, Beijing Normal University, State Key Laboratory of Remote Sensing Science, Beijing Key Laboratory for Remote Sensing of Environment and Digital Cities, Beijing 100875, China Department of Mathematics, Beijing Normal University, Beijing 100875, China | 2005 | Science China Earth Sciences2005，48，1： | 12 |

| 9 | Land Use Allocation Based on Interval Multi-objective Linear Programming Model: A Case Study of Pi County in Sichuan Province显示文摘Adjusting and optimizing land use structure is one of the essential approaches to solve the conflict between land supply and demand. In this study,an uncertain interval multi-objective linear programming model was established and applied to analyzing the suitability of land use structure in Pi County of Sichuan Province. An adjustment scheme for optimizing land use structure was proposed on the basis of development planning drawn up by the local government. The results are summarized as follows: 1) the optimal adjustment scope for cropland area ranges from 27 976.75 ha to 31 029.08 ha,and the current area is less than the lower limit of the scope; 2) the optimal adjustment scope for garden land area ranges from 4 736.49 ha to 12 967.11 ha,and the current area is less than the lower limit; 3) the optimal adjustment scope for construction land ranges from 7 761.95 ha to 10 393.18 ha,and the current area is greater than the upper limit; 4) the optimal adjustment scope for industry and mining land ranges from 557.29 ha to 693.54 ha,and the current area exceeds the upper limit; and 5) the areas of forest land,grassland and other agricultural land are within the optimal adjustment scope. In order to maximize comprehensive benefit with the limited resources and the demand of sustainable development,the areas of cropland and garden land are supposed to be expanded properly,while the construction land should be controlled and reduced gradually,and the forest land and other agricultural land can be maintained at the current level in short period. | WANG Hongrui GAO Yuanyuan LIU Qiong SONG Jinxi | 2010 | Chinese Geographical Science2010，20，2： | 10 |

| 11 | Advances of research on high-speed railway catenary显示文摘The interaction between the catenary and pantograph is one of the most crucial factors that determine the train operation in high-speed railway. The bad state of catenary is able to directly influence the power supply safety of traction power system. In this paper, four aspects on the catenary research of high-speed railway are reviewed in detail, namely the solution methods for catenary equilibrium state, the dynamic modeling methods of catenary, the non-contact detection methods of catenary, and the static and dynamic evaluation methods of catenary. In addition, their recent advances are described. For the low solution accuracy of the initial equilibrium state of catenary, the structure finding method with multi-objective constraint and nonlinear finite element procedure are introduced to solve the problem. For the catenary's dynamic modeling, considering the influence of environmental wind on the catenary, environmental wind simulations and wind tunnel tests are used to obtain theaerodynamic coefficients and build the wind field along the catenary for analysis of its wind vibration characteristics.In order to improve the detection accuracy of non-contact detection for the catenary, the deep learning theory and real-time detection algorithms should be adopted in the future. In view of the lack of dynamic assessment method for the catenary, the modern spectrum evaluation, time–frequency analysis, big data technology and their combinations will be the important means for future catenary evaluation. | Zhigang Liu Yang Song Ye Han Hongrui Wang Jing Zhang Zhiwei Han | 2018 | Journal of Modern Transportation2018，26，1： | 9 |
| 12 | Convex shaping process simulation during counter-rotating electrochemical machining by using the finite element method显示文摘In counter-rotating electrochemical machining(CRECM), a revolving cathode tool with hollow windows of various shapes is used to fabricate convex structures on a revolving part. During this process, the anode workpiece and the cathode tool rotate relative to each other at the same rotation speed. In contrast to the conventional schemes of ECM machining with linear motion of a block tool electrode, this scheme of ECM is unique, and has not been adequately studied yet. In this paper, the finite element method(FEM) is used to simulate the anode shaping process during CRECM, and the simulation process which involves a meshing model, a moving boundary,and a simulation algorithm is described. The simulated anode profiles of the convex structure at different processing times show that the CRECM process can be used to fabricate convex structures of various shapes with different heights. Besides, the variation of the inter-electrode gap indicates that this process can also reach a relative equilibrium state like that in conventional ECM. A rectangular convex and a circular convex are successfully fabricated on revolving parts. The experimental results indicate relatively good agreement with the simulation results. The proposed simulation process is valid for convex shaping prediction and feasibility studies as well. | Wang Dengyong Zhu Zengwei Wang Hongrui Zhu Di | 2016 | Chinese Journal of Aeronautics2016，29，2： | 8 |
| 13 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022，42，12： | 8 |
| 14 | Adsorption and Desorption Behavior of Tannic Acid in Aqueous Solution on Polyaniline Adsorbent显示文摘Tannic acid is generally considered as one of polyphenolic pollutants, which may cause severe threats to the environment. In this study, polyaniline adsorbent was synthesized by chemical oxidation to remove tannic acid in aqueous solutions. The adsorption amount of tannic acid varied greatly with pH of solution and strong adsorption was at pH 5.8-6.7. Coexisting cations, such as Na+, K+, and Ca2+, can enhance the adsorption of tannic acid on poly-aniline, which may be contributed to the electrostatic interaction between tannic acid and polyaniline. The adsorp-tion process could be well described by Langmuir model and the maximum adsorption capacity was 117.65 mg·g-1 at 35 ℃ and pH 6.0. The thermodynamic parameters calculated from the adsorption isotherms indicate that the ad-sorption of tannic acid is spontaneous and endothermic process. The polyaniline saturated with tannic acid can be desorbed in alkaline solution and regenerated adsorbent can be used repeatedly with high adsorption capacity, which implies that polyaniline adsorbents have a great potential in water purification for the removal of tannic acid. | WANG Jiahong JI Yan fen DING Shaolan MA Hongrui HAN Xiaojing | 2013 | Chinese Journal of Chemical Engineering2013，21，6： | 7 |
| 15 | Uncertainty analysis of hydrological processes based on ARMA-GARCH model显示文摘Uncertainty analysis and risk analysis are two important areas of modern water resource management,in which accurate variance estimation is required.The traditional runoff model is established under the assumption that the variance is a constant or it changes with the seasons.However,hydrological processes in the real world are often heteroscedastic,which can be tested by McLeod-Li test and Engle Lagrange multiplier test.In such cases,the GARCH model of hydrological processes is established in this article.First,the seasonal factors in the sequence are removed.Second,the traditional ARMA model is established.Then,the GARCH model is used to correct the residual.At last,the daily runoff data in 1949-2001 of Yichang Hydrological Station is taken to be an example.The result shows that compared to the traditional ARMA model,the GARCH model has the ability to predict more accurate confidence intervals under the same confidence level. | WANG HongRui GAO Xiong QIAN LongXia YU Song | 2012 | Science China(Technological Sciences)2012，55，8： | 6 |
| 16 | Mineral photoelectrons and their implications for the origin and early evolution of life on Earth显示文摘Energy is the key issue of all life activities.The energy source and energy yielding pathway are the key scientific issues of the origin and early evolution of life on Earth.Current researches indicate that the utilization of solar energy in large scale by life was an important breaking point of the early evolution of life on Earth and afterwards life gradually developed and flourished.However,in the widespread biochemical electron transfer of life activities,it is still not clear whether the electron source is sun or how electrons originated from sun.For billions of years,the ubiquitous semiconducting minerals in epigeosphere absorb solar energy,forming photoelectrons and photoholes.In reductive and weak acidic environment of early Earth,when photoholes were easily scavenged by reducing matters,photoelectrons were separated.Photoelectrons could effectively reduce carbon dioxide to organic matters,possibly providing organic matter foundation for the origin of life.Photoelectrons participated in photoelectron transfer chains driven by potential difference and transfer into primitive cells to maintain metabolisms.Semiconducting minerals,by absorbing ultraviolet,also protected primitive cells from being damaged by ultraviolet in the origin of life.Due to the continuous photoelectrons generation in semiconducting minerals and utilization by primitive cells,photoelectrons from semiconducting minerals’photocatalysis played multiple roles in the origin of life on early Earth,such as organic synthesis,cell protection,and energy supply.This mechanism still plays important roles in modern Earth surface systems. | LU AnHuai WANG Xin LI Yan DING HongRui WANG ChangQiu ZENG CuiPing HAO RuiXia YANG XiaoXue | 2014 | Science China Earth Sciences2014，57，5： | 5 |
| 17 | Metallogeny of the Baiyangping Lead-Zinc Polymetallic Ore Concentration Area, Northern Lanping Basin of Yunnan Province, China显示文摘The Lanping Basin in the Nujiang-Lancangjiang-Jinshajiang(the Sanjiang) area of northeastern margin of the Tibetan Plateau is an important part of eastern Tethyan metallogenic domain. This basin hosts a number of large unique sediment-hosted Pb-Zn polymetallic deposits or ore districts, such as the Baiyangping ore concentration area which is one of the representative ore district. The Baiyangping ore concentration area can be divided into the east and west ore belts, which were formed in a folded tectogene of the India-Asia continental collisional setting and was controlled by a large reverse fault. Field observations reveal that the Mesozoic and Cenozoic sedimentary strata were outcropped in the mining area, and that the orebodies are obviously controlled by faults and hosted in sandstone and carbonate rocks. However, the ore-forming elements in the east ore belt are mainly Pb-Zn-Sr-Ag, while Pb-Zn-Ag-Cu-Co elements are dominant in the west ore belt. Comparative analysis of the C-O-Sr-S-Pb isotopic compositions suggest that both ore belts had a homogeneous carbon source, and the carbon in hydrothermal calcite is derived from the dissolution of carbonate rock strata; the oreforming fluids were originated from formation water and precipitate water, which belonged to basin brine fluid system; sulfur was from organic thermal chemical sulfate reduction and biological sulfate reduction; the metal mineralization material was from sedimentary strata and basement, but the difference of the material source of the basement and the strata and the superimposed mineralization of the west ore belt resulted in the difference of metallogenic elements between the eastern and western metallogenic belts. The Pb-Zn mineralization age of both ore belts was contemporary and formed in the same metallogenetic event. Both thrust formed at the same time and occurred at the Early Oligocene, which is consistent with the age constrained by field geological relationship. | WANG Xiaohu SONG Yucai ZHANG Hongrui LIU Yingchao PAN Xiaofei GUO Tao | 2018 | Acta Geologica Sinica(English Edition)2018，92，4： | 5 |
| 18 | Late Carboniferous to early Permian sedimentaryetectonic evolution of the north of Alxa, Inner Mongolia, China: Evidence from the Amushan Formation显示文摘The late Paleozoic evolution of the Wulijishanhen(WSH)-Shangdan(SD) area near to the Chaganchulu Ophiolite belt is reinterpreted. Analysis of the upper Carboniferous to lower Permian sedimentary sequence, biological associations, detrital materials, sandstone geochemistry and volcanic rocks indicates that the SD area was an epicontinental sea and rift during the late Paleozoic rather than a large-scale ocean undergoing spreading and closure. This study reveals that the actual evolution of the study area is from the late Carboniferous to the early Permian. The fusulinids Triticites sp. and Pseudoschwagerina sp.in the limestones demonstrate that the Amushan Formation develops during the late Carboniferous to the early Permian. The limestones at the base of the SD section indicate that it is a stable carbonate platform environment, the volcanic rocks in the middle of the sequence support a rift tectonic background, and the overlying conglomerates and sandstones are characteristic of an epicontinental sea or marine molasse setting. The rift volcanism made the differences in the fossil content of the SD and WSH sections and led to two sections expose different levels within the Amushan Formation and different process of tectonic evolution. Moreover, the geochemical characteristics and detrital materials of the sandstones show that the provenance and formation of the sandstones were related to the setting of active continental margin. The quartz-feldspar-lithic fragments distribution diagram indicates that the material source for the sandstones was a recycled orogenic belt. Thus, the source area of the sandstones may have been an active continental margin before the late Carboniferouseearly Permian. The characteristics of the regional tectonic evolution of the area indicate that the region may form a small part of the Gobie Tianshan rift of southern Mongolia. | Haiquan Yin Hongrui Zhou Weijie Zhang Xiaoming Zheng Shengyu Wang | 2016 | Geoscience Frontiers2016，7，5： | 5 |
| 19 | Flow Development Through HP&LP Turbines,PartⅡ:Effects of the Hub Endwall Secondary Sealing Air Flow on the Turbine's Mainstream Flow显示文摘Although many literatures have been focused on the underneath flow and loss mechanism, very few experiments and simulations have been done under the engines' representative working conditions or considering the real cavity structure as a whole. This paper aims at realizing the goal of design of efficient turbine and scrutinizing the velocity distribution in the vicinity of the rim seal. With the aid of numerical method, a numerical model describing the flow pattern both in the purge flow spot and within the mainstream flow path is established, fluid migration and its accompanied flow mechanism within the realistic cavity structure(with rim seal structure and considering mainstream & secondary air flow's interaction) is used to evaluate both the flow pattern and the underneath flow mechanism within the inward rotating cavity. Meanwhile, the underneath flow and loss mechanism are also studied in the current paper. The computational results show that the sealing air flow's ingestion and ejection are highly interwound with each other in both upstream and downstream flow of the rim seal. Both the downstream blades' potential effects as well as the upstream blades' wake trajectory can bring about the ingestion of the hot gas flow within the cavity, abrupt increase of the static pressure is believed to be the main reason. Also, the results indicate that sealing air flow ejected through the rear cavity will cause unexpected loss near the outlet section of the blades in the downstream of the HP rotor passages. | HU Jialin DU Qiang LIU Jun WANG Pei LIU Guang LIU Hongrui DU Meimei | 2017 | Journal of Thermal Science2017，26，4： | 4 |
| 20 | Slope stability prediction using ensemble learning techniques: A case study in Yunyang County, Chongqing, China显示文摘Slope stability prediction plays a significant role in landslide disaster prevention and mitigation.This study develops an ensemble learning-based method to predict the slope stability by introducing the random forest(RF)and extreme gradient boosting(XGBoost).As an illustration,the proposed approach is applied to the stability prediction of 786 landslide cases in Yunyang County,Chongqing,China.For comparison,the predictive performance of RF,XGBoost,support vector machine(SVM),and logistic regression(LR)is systematically investigated based on the well-established confusion matrix,which contains the known indices of recall rate,precision,and accuracy.Furthermore,the feature importance of the 12 influencing variables is also explored.Results show that the accuracy of the XGBoost and RF for both the training and testing data is superior to that of SVM and LR,revealing the superiority of the ensemble learning models(i.e.XGBoost and RF)in the slope stability prediction of Yunyang County.Among the 12 influencing factors,the profile shape is the most important one.The proposed ensemble learning-based method offers a promising way to rationally capture the slope status.It can be extended to the prediction of slope stability of other landslide-prone areas of interest. | Wengang Zhang Hongrui Li Liang Han Longlong Chen Lin Wang | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，4： | 4 |
