| 1 | Numerical simulation study of the failure evolution process and failure mode of surrounding rock in deep soft rock roadways显示文摘Based on the safety coefficient method,which assigns rock failure criteria to calculate the rock mass unit,the safety coefficient contour of surrounding rock is plotted to judge the distribution form of the fractured zone in the roadway.This will provide the basis numerical simulation to calculate the surrounding rock fractured zone in a roadway.Using the single factor and multi-factor orthogonal test method,the evolution law of roadway surrounding rock displacements,plastic zone and stress distribution under different conditions is studied.It reveals the roadway surrounding rock burst evolution process,and obtains five kinds of failure modes in deep soft rock roadway.Using the fuzzy mathematics clustering analysis method,the deep soft surrounding rock failure model in Zhujixi mine can be classified and patterns recognized.Compared to the identification results and the results detected by geological radar of surrounding rock loose circle,the reliability of the results of the pattern recognition is verified and lays the foundations for the support design of deep soft rock roadways. | Meng Qingbin Han Lijun Xiao Yu Li Hao Wen Shengyong Zhang Jian | 2016 | International Journal of Mining Science and Technology2016，26，2： | 14 |
| 2 | Influence of dynamic pressure on deep underground soft rock roadway support and its application显示文摘Due to high ground stress and mining disturbance, the deformation and failure of deep soft rock roadway is serious, and invalidation of the anchor net-anchor cable supporting structure occurs. The failure characteristics of roadways revealed with the help of the ground pressure monitoring. Theoretical analysis was adopted to analyze the influence of mining disturbance on stress distribution in surrounding rock,and the change of stress was also calculated. Considering the change of stress in surrounding rock of bottom extraction roadway, the displacement, plastic zone and distribution law of principal stress difference under different support schemes were studied by means of FLAC3D. The supporting scheme of U-shaped steel was proposed for bottom extraction roadway that underwent mining disturbance. We carried out a similarity model test to verify the effect of support in dynamic pressure. Monitoring results demonstrated the change rules of deformation and stress of surrounding rock in different supporting schemes. The supporting scheme of U-shaped steel had an effective control on deformation of surrounding rock. The scheme was successfully applied in underground engineering practice, and achieved good technical and economic benefits. | Meng Qingbin Han Lijun Chen Yanlong Fan Jiadong Wen Shengyong Yu Liyuan Li Hao | 2016 | International Journal of Mining Science and Technology2016，26，5： | 4 |
| 3 | Quantitative research of diagenesis:its effect on pore evolution of the Fuyu oil reservoir in the north Qijia region显示文摘From observing cores of 18 wells,identifying 175 ordinary thin sections and 61 thin casting sections,energy spectrum analyses of 37 samples,homogenization temperature measurement of fluid inclusions of 11 samples,we determine the types of diagenesis and pores of the Fuyu oil reservoir in the north Qijia region.We classified the pores and measured their plane porosity using CIA 2000,the software of rock image analysis,calculated the effect of different kinds of diagenesis on porosity,studied the controlling actions of diagenesis to pore evolution quantitatively,combined with burial history,thermal history and their diagenetic environments.Our results show that mechanical compaction and carbonate cementation are the major destructive diagenesed,developed during early diagenesis stages.The reduction in porosity by mechanical compaction and carbonate cementation are about 25% and 8%,while the destructive intensity of siliceous cementation and clay mineral cementation is relatively much smaller,i.e.,the reduction of porosity is about 2% and 0.2% Dissolution is constructive diagenesis,the increment of porosity is about 6%.There are four diagenesis evolution stages,during which the porosity reduced from 30%~38% to 2%~20%.Mechanical compaction and early cementation are the main diageneses in the early diagenesis stages,when porosity was reduced to 2%~10%.Dissolution is the main diagenesis of an A I substage of the middle diagenesis stage,when porosity increased 1%~8%.The dissolution of the A Ⅱ substage of the middle diagenesis stage affected by late cementation,raised porosity 1%~5%.The porosity varied slightly during the middle stage B. | HAO Guoli SHAN Xuanlong LIU Wanzhu WANG Qingbin | 2010 | Mining Science and Technology2010，20，5： | 4 |
| 4 | Production of Fibres from Lunar Soil:Feasibility,Applicability and Future Perspectives显示文摘The construction of a lunar base is considered to be an important step towards deep-space exploration by humanity,and will rely on the utilisation of in situ lunar resources.In this paper,we discuss the current knowledge on the feasibility of converting lunar soil to high-performance fibres that can be used for the construction of a lunar base.This fibre would be combined with further portions of lunar soil to generate fibre-reinforced composites,which is utilized as multi-functional materials for lunar base construction.We discuss and analyse the latest findings regarding the composition of lunar soil simulants and their fibrisation properties,and techniques for fibre spinning and system integration.Finally,we suggest how the achievements made so far could be applied to the construction of a lunar base. | Ze‑Shi Guo Dan Xing Xiong‑Yu Xi Xiu Yue Cun‑Guang Liang Bin Hao Qingbin Zheng Sergey I.Gutnikov Bogdan I.Lazoryak Peng‑Cheng Ma | 2022 | Advanced Fiber Materials2022，4，5： | 2 |
| 5 | Multiple forms of vitamin B_(6) regulate salt tolerance by balancing ROS and abscisic acid levels in maize root显示文摘Salt stress causes osmotic stress,ion toxicity and oxidative stress,inducing the accumulation of abscisic acid(ABA)and excessive reactive oxygen species(ROS)production,which further damage cell structure and inhibit the development of roots in plants.Previous study showed that vitamin B_(6)(VB_(6))plays a role in plant responses to salt stress,however,the regulatory relationship between ROS,VB_(6) and ABA under salt stress remains unclear yet in plants.In our study,we found that salt stress-induced ABA accumulation requires ROS production,in addition,salt stress also promoted VB_(6)(including pyridoxamine(PM),pyridoxal(PL),pyridoxine(PN),and pyridoxal 5′-phosphate(PLP))accumulation,which involved in ROS scavenging and ABA biosynthesis.Furthermore,VB_(6)-deficient maize mutant small kernel2(smk2)heterozygous is more susceptible to salt stress,and which failed to scavenge excessive ROS effectively or induce ABA accumulation in maize root under salt stress,interestingly,which can be restored by exogenous PN and PLP,respec-tively.According to these results,we proposed that PN and PLP play an essential role in balancing ROS and ABA levels under salt stress,respectively,it laid a foundation for VB_(6) to be better applied in crop salt resistance than ABA. | Chongchong Lu Yuan Tian Xuanxuan Hou Xin Hou Zichang Jia Min Li Mingxia Hao Yanke Jiang Qingbin Wang Qiong Pu Ziyi Yin Yang Li Baoyou Liu Xiaojing Kang Guangyi Zhang Xinhua Ding Yinggao Liu | 2022 | Stress Biology2022，2，1： | 1 |
| 6 | Division and identification of vertical reservoir units in Archaeozoic metamorphic buried hill of Bozhong Sag,Bohai Bay Basin,East China显示文摘Based on the data associated with cores,sidewall cores,casting thin sections,reservoir physical properties,conventional logging and imaging logging,the classification schemes of vertical reservoir units are proposed for the two types of Archaeozoic buried hills(exposed and covered ones)in the Bozhong Sag,Bohai Bay Basin.The geological characteristics and storage spaces of these reservoir units are described,and their identification markers in conventional and imaging log curves are established.The Archaeozoic metamorphic buried hills can be vertically classified into two primary reservoir units:weathering crust and inner buried hill.The weathering crust contains four secondary units,i.e.,the clay zone,weathered glutenite zone,leached zone,disaggregation zone;and the interiors contain two secondary units,i.e.,interior fracture zone and tight zone.In particular,the inner fracture zone was further divided into cataclasite belts and dense-fracture belts.It is proposed that the favorable reservoirs of exposed Archaeozoic metamorphic buried hills are mainly developed in four parts including weathered glutenite zone,leached zone,disintegration zone superposed with the cataclasite belt and the cataclasite belt of inner fracture zone,and are controlled by both weathering and tectonic actions.Favorable reservoirs in covered Archaeozoic metamorphic buried hills are mainly developed in the weathering crust superposed with the cataclasite belts and the cataclasite belts of inner fracture zone,and are mainly controlled by tectonic actions. | YI Jian LI Huiyong SHAN Xuanlong HAO Guoli YANG Haifeng WANG Qingbin XU Peng REN Shuyue | 2022 | Petroleum Exploration and Development2022，49，6： | 1 |
| 7 | Phase Evolution Study and Optimization of the Heat Treatment Process for High Current Capacity Bi-2223 Tapes显示文摘Powder in tube process(PIT) was adopted for the fabrication of single filament Bi-2223 tapes, and a heat treatment process including the first heat treatment(HT1), intermediate rolling(IR), and second heat treatment(HT2) was performed. The phase evolution mechanism and microstructure changes during these heat treatment processes were systematically discussed. The influences of HT1 parameters on the phase evolution process of Bi-2223 tapes were discussed. With the optimized HT1 process, a proper Bi-2223 content of about 90% was achieved. HT2 process was also optimized by adding a post annealing process. An obvious increase of current capacity was obtained due to the enhancement of intergrain connections. Single filament Bi-2223 tapes with the critical current of I_c-90 A were fabricated with the optimized sintering process. | 白利锋 张胜楠 LI Chengshan HAO Qingbin LIU Guoqing ZHANG Pingxiang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，4： | 1 |

| 9 | A solvent-free,selective liquid phase hydrogenation of nitroarenes to aniline in slurry bubble mode on porous NiMo bimetallic catalyst显示文摘NiMo bimetallic catalysts were prepared by a solid reaction method.On the NiMo catalyst,the selective liquid phase hydrogenation of nitrobenzene to aniline was achieved in slurry bubble mode.And the high yields(98.9%)were obtained under the conditions of 80℃,solvent-free and atmospheric pressure.The effect of Mo on the catalytic behavior of Ni based catalyst was investigated.The characterization displayed that the inclusion of Mo could improve the specific surface area and pore volume,and the solid reaction method made metal Mo enrichment on the surface of catalyst.These two aspects should be responsible for excellent catalytic performance of NiMo catalyst.In sum,we described a simple and efficient NiMo catalyst and provided a facile and green procedure for liquid phase hydrogenation of nitrobenzene to aniline. | Di Liu Pengshan Zhao Hao Zhang Minjie Liu Junyan Wang Guoming Zhao Qingbin Guo | 2021 | Chinese Journal of Chemical Engineering2021，34，5： | 0 |
| 10 | Antibody-dependent cellular cytotoxicity response to SARS-CoV-2 in COVID-19 patients显示文摘Antibody-dependent cellular cytotoxicity(ADCC)responses to viral infection are a form of antibody regulated immune responses mediated through the Fc fragment.Whether severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)triggered ADCC responses contributes to COVID-19 disease development is currently not well understood.To understand the potential correlation between ADCC responses and COVID-19 disease development,we analyzed the ADCC activity and neutralizing antibody response in 255 individuals ranging from asymptomatic to fatal infections over 1 year post disease.ADCC was elicited by 10 days post-infection,peaked by 11-20 days,and remained detectable until 400 days post-infection.In general,patients with severe disease had higher ADCC activities.Notably,patients who had severe disease and recovered had higher ADCC activities than patients who had severe disease and deceased.Importantly,ADCC activities were mediated by a diversity of epitopes in SARS-COV-2-infected mice and induced to comparable levels against SARS-CoV-2 variants of concern(VOCs)(B.1.1.7,B.1.351,and P.1)as that against the D614G mutant in human patients and vaccinated mice.Our study indicates anti-SARS-CoV-2 ADCC as a major trait of COVID-19 patients with various conditions,which can be applied to estimate the extra-neutralization level against COVID-19,especially lethal COVID-19. | Yuanling Yu Meiyu Wang Xiaoai Zhang Shufen Li Qingbin Lu Haolong Zeng Hongyan Hou Hao Li Mengyi Zhang Fei Jiang Jiajing Wu Ruxia Ding Zehua Zhou Min Liu Weixue Si Tao Zhu Hangwen Li Jie Ma Yuanyuan Gu Guangbiao She Xiaokun Li Yulan Zhang Ke Peng Weijin Huang Wei Liu Youchun Wang | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 0 |
| 11 | Summer habitat selection and impacts of human disturbance on leopard cats(Prionailurus bengalensis)显示文摘Introduction:As a consequence of habitat loss and degradation,the leopard cat(Prionailurus bengalensis)in China has become endangered and in need of urgent protection.In situ conservation of leopard cats must be based on an understanding of their habitat selection patterns.We studied the summer habitat of leopard cats using line-transect surveys in the northern Taihang Mountain region surrounding Beijing,China.We compared used plots with non-used plots in elevation,tree canopy,and 20 other ecological variables,and used Vanderploeg��Scavia’s resource selection index(VSI)to analyze habitat preferences.Outcomes/others:Results show that tree canopy,tree height,tree density,and stump quantity of used plots were significantly lower than non-used plots in summer,and that leopard cats preferred habitats located on northern,flat slopes with lower slope,shrub-dominated,dry soil,and less fallen-wood.Leopard cats had a strong tendency to use habitats near human disturbance areas with moderate levels of disturbance intensity.Conclusion:The results suggest that future conservation efforts should emphasize:(1)strengthening the protection and management of forest fringe shrub habitats to improve summer habitat suitability,and(2)environmental education and animal protection campaigns to promote community biodiversity conservation. | Jiayi Wu Jing Wang Yinjiu Zhu Xiangli Bu Rongwei Xiang Qingbin Lu Shaopeng Cui Yinghong Hao Yan Sheng Xiuxiang Meng | 2020 | Ecosystem Health and Sustainability2020，6，1： | 0 |
