| 1 | Aerodynamic design for China new high-speed trains显示文摘High-speed trains have very complex running environments,which contain single-train running in open air,two-trains passing by in open air,single-train running in tunnel and two-trains passing by in tunnel.When the environment wind appears,crosswind effects must be considered.Aerodynamic design of high-speed trains mainly aims at the drag,lift,moment,impulse pressure waves,aerodynamic noise,etc.at typical running conditions.In the paper,the aerodynamic design processes of CRH380A and 380B are introduced and the aerodynamic performances of different designs are analyzed and compared.Wind tunnel experiments and running tests indicate that the new generation of high-speed trains have excellent aerodynamic performances. | YANG GuoWei GUO DiLong YAO ShuanBao LIU ChengHui | 2012 | Science China(Technological Sciences)2012，55，7： | 18 |
| 2 | An overview of design for CSNS/RCS and beam transport显示文摘The China Spallation Neutron Source (CSNS) is the first accelerator-based pulsed neutron source in China. Its accelerators are made up of an 80 MeV H- linac, a Rapid Cycling Synchrotron (RCS) and two beam transport lines. RCS accumulates and accelerates protons to the design energy of 1.6 GeV, and extracts high energy beam to strike the target. The overview of RCS is presented, and the key problems of the physics design are discussed. The two beam transport lines, from linac to RCS and from RCS to the target, are also introduced. | WANG Sheng AN YuWen FANG ShouXian HUANG Nan LIU WeiBin LIU YuDong QIN Qing QIU Jing WANG Na XU Gang XU ShouYan YU ChengHui | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 11 |
| 3 | Developing a bacteriophage cocktail for biocontrol of potato bacterial wilt显示文摘Bacterial wilt is a devastating disease of potato and can cause an 80% production loss. To control wilt using bacteriophage therapy, we isolated and characterized twelve lytic bacteriophages from different water sources in Kenya and China. Based on the lytic curves of the phages with the pathogen Ralstonia solanacearum, one optimal bacteriophage cocktail, P1, containing six phage isolations was formulated and used for studying wilt prevention and treatment efficiency in potato plants growing in pots. The preliminary tests showed that the phage cocktail was very effective in preventing potato bacterial wilt by injection of the phages into the plants or decontamination of sterilized soil spiked with R. solanacearum. Eighty percent of potato plants could be protected from the bacterial wilt(caused by R. solanacearum reference strain GIM1.74 and field isolates), and the P1 cocktail could kill 98% of live bacteria spiked in the sterilized soil at one week after spraying.However, the treatment efficiencies of P1 depended on the timing of application of the phages, the susceptibility of the plants to the bacterial wilt, as well as the virulence of the bacteria infected,suggesting that it is important to apply the phage therapy as soon as possible once there are early signs of the bacterial wilt. These results provide the basis for the development of bacteriophagebased biocontrol of potato bacterial wilt as an alternative to the use of antibiotics. | Cuihua Wei Junli Liu Alice Nyarnbura Maina Francis B Mwaura Junping Yu Chenghui Yan Ruofang Zhang Hongping Wei | 2017 | Virologica Sinica2017，32，6： | 8 |
| 4 | A Preliminary Review of Metallogenic Regularity of Molybdenum Deposits in China显示文摘Molybdenum is one of the dominant minerals in China because of its rich reserves.In recent years,outstanding breakthroughs have been made in molybdenum prospecting in China,and the distribution of molybdenum deposits in China is found to have a 'planar pattern'.In general,the molybdenum deposits are concentrated in eastern China,including the largest molybdenum reserves of Henan Province.In terms of the scale of molybdenum deposits,the identified resources of the superlarge deposits are the most important,which account for about 53% of the whole country,and those of the large deposits account for about 30%,those of the medium-sized deposits account for about 14%,those of the small-sized deposits,mine spots and mineralization account for about 3%.The molybdenum deposits are mainly classified as porphyry type,skarn type,hydrothermal(vein) type and sedimentary(metamorphic) type in genesis,and the identified resources of these types account for 85.75%,8.83%,2.79%and 2.63% of the total resources respectively.Based on the statistics of precise chronology data of molybdenites Re-Os,Mo-mineralization can be divided into 6 periods in Chinese geological history,which are Precambrian(>800 Ma),Cambrian-Silurian(540-415 Ma,Caledonian),Devonian-Permian(400-290 Ma,Hecynian),Triassic(260-200 Ma,Indosinian),Jurassic-Cretaceous(195-70 Ma,Yanshanian) and Paleogene-Neogene(65-10 Ma,Himalayan).Mo mineralization during the Yanshanian period is the strongest one,in which about 76.69% of the Chinese total identified resources was formed.The second is the Himalayan period.According to spatial-temporal distribution characteristics of molybdenum deposits,the metallogenic regularity of molybdenum deposits was preliminarily summarized,and 41 level-Ⅲ molybdenum-forming belts,13 level-Ⅱ molybdenum-forming provinces and 4 level-Ⅰ molybdenum-forming domains were ascertained in the mainland of China.There are 39 metallogenic series of and 60 sub-series of molybdenum deposits with molybdenum as the dominant metal and corresponding representative molybdenum deposits proposed.Metallogenic lineages of molybdenum deposits were also established.Spatial-temporal evolution of different types of molybdenum deposits,and the relationship between Mo-mineralization and tectonic evolution have been discussed in this paper.On this basis,the authors think that element Mo is an effective tracer for recording the crustal evolution history of China.At present,there are some problems in the exploration of Mo deposits in China,such as uneven exploration degrees in eastern and western China,shallow exploration depth,low and uneven grade,complex associated components,difficulty of mineral development and utilization,increasing costs of prospecting,and so on.According to successful experience of superficial and deep prospecting and considering also the discussion above,some suggestions are proposed for the prospecting of molybdenum deposits in the future. | HUANG Fan LIU Xinxing WANG Denghong WANG Chenghui | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 7 |
| 5 | Robust stability and H-infinity control for uncertain discrete-time Markovian jump singular systems显示文摘The robust stability and stabilization, and H-infinity control problems for discrete-time Markovian jump singular systems with parameter uncertainties are discussed. Based on the restricted system equivalent (r.s.e.) transformation and by introducing new state vectors, the singular system is transformed into a discrete-time Markovian jump standard linear system, and the linear matrix inequality (LMI) conditions for the discrete-time Markovian jump singular systems to be regular, causal, stochastically stable, and stochastically stable with γ-disturbance attenuation are obtained, respectively. With these conditions, the robust state feedback stochastic stabilization problem and H-infinity control problem are solved, and the LMI conditions are obtained. A numerical example illustrates the effectiveness of the method given in the paper. | Shuping MA Chenghui ZHANG Xinzhi LIU | 2008 | 控制理论与应用(英文版)2008，6，2： | 6 |
| 6 | Surface modification of hydrophobic NaYF_4:Yb,Er upconversion nanophosphors and their applications for immunoassay显示文摘β-NaYF4:Yb,Er upconversion nanophosphor (UCNP) is known as one of the most efficient NIR-to-visible upconversion materials, which shows great potential in bioanalytical chemistry and bioimaging. However, its applications are greatly limited due to its low water dispersibility and thus poor biocompatibility. In this paper, poly(acrylic acid) (PAA)-based ligand exchange strategies are carried out to modify oleic acid-capped hydrophobic β-NaYF4:Yb,Er UCNPs into hydrophilic ones. After efficient surface modification, the presence of free carboxylic acid groups on the surfaces of UCNPs results in high solubility in water, and also allows further conjugation with NH2-containing biomolecules. Facilitated by the covalent linkage between the-COOH groups on UCNPs surfaces and -NH2 groups in antigen/antibody, a sensitive immunosensor is constructed by using PAA-functionalized β-NaYF4:Yb,Er UCNPs as biolabels. Through monitoring the upconversion fluorescence intensity or fluorescent imaging of the final immunocomplexes, high sensitivity is achieved for the proposed immunoassay and as low as 0.1 ng/mL goat anti-human immunoglobulin G (IgG) can be detected, which suggests that PAA-modified UCNPs may serve as an ideal candidate for use as bioanalysis and bioimaging probes. | LIU ChengHui, WANG Zhe, WANG XiaoKe & LI ZhengPing Key Laboratory of Medicinal Chemistry and Molecular Diagnosis, Ministry of Education College of Chemistry and Environmental Science, Hebei University, Baoding 071002, China | 2011 | Science China Chemistry2011，54，8： | 6 |
| 7 | A Preliminary Review of Metallogenic Regularity of Gold Deposits in China显示文摘Gold is one of the most important mineral resources in China with its rich mineral resources. In recent years,significant progress has been made on the process of gold resource exploration. Some large and giant gold deposits were newly found and some important expansions in the main mining regions were also been completed. Studies on metallogenic regularity of gold deposits in China also have made achievements with a long–term work. This review aims to conclude the achievements of research on gold metallogenic regularity in China. Based on the data of about 2000 gold deposits and other ore(mineralized) occurrences,gold deposits in China were classified into five prediction types: gold deposits genetically related to granite–greenstone formation,gold deposits related to sedimentary formation(including the Carlin type and the metamorphosed clastic rock related vein gold deposit),gold deposits genetically related to volcanic rocks(including the continental and marine types),gold deposits genetically related to intrusions(including the porphyry type and the inner intrusion and contact zone related gold deposit),gold deposits of supergenesis(including fracture zone–altered rock gold deposit,placer gold deposit,gossan type gold deposit and soil type gold deposit). Statistics on precise chronology data of gold deposits indicate that there occurred 5 main periods of gold–mineralization in geological history of China. They were Neoarchean to Paleoproterozoic,Meso–Neoproterozoic,Paleozoic,Mesozoic,and Cenozoic. Gold deposits in China mainly formed in the Mesozoic and the Cenozoic. On the studies of the spatial–temporal distribution characteristics of gold deposits,53 gold–forming belts were delineated in China. The metallogenic regularity of gold deposits was preliminarily summarized and 71 gold metallogenic series were proposed in China. This suggests that it is necceary to deepen the study on metallogenic regularity of gold deposits and to provide the theory guide for the ore–prospecting for gold resources in China. | WANG Chenghui WANG Denghong XU Jue YING Lijuan LIU Lijun LIU Shanbao | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 4 |
| 8 | Platelet-mediated adhesion facilitates leukocyte sequestration in hypoxia-reoxygenated microvessels显示文摘Leukocyte transendothelial migration and sequestration are two distinct outcomes following leukocyte adhesion to endothelium during ischemia-reperfusion injury, in which platelets may play a pivotal role. In the present study, we established an in vitro hypoxia-reoxygenation model to mimic ischemia-reperfusion injury and found platelet pre-incubation significantly increased leukocyte adhesion to endothelial cells after hyoxia-reoxygenation(over 67%). Blockade of endothelial-cell-expressed adhesion molecules inhibited leukocyte direct adhesion to endothelial cells, while platelet-mediated leukocyte adhesion was suppressed by blockade of platelet-expressed adhesion molecules. Further experiments revealed platelets acted as a bridge to mediate leukocyte adhesion, and platelet-mediated adhesion was the predominant pattern in the presence of platelets. However, platelet pre-incubation significantly suppressed leukocyte transendothelial migration after hypoxia-reoxygenation(over 31%), which could be aggravated by blockade of endothelial-cell-expressed adhesion molecules, but alleviated by blockade of platelet-expressed adhesion molecules. This would indicate that platelet-mediated adhesion disrupted leukocyte transendothelial migration. An in vivo mesenteric ischemia-reperfusion model demonstrated leukocyte transfusion alone caused mild leukocyte adhesion to reperfused vessels and subsequent leukocyte infiltration, while simultaneous leukocyte and platelet transfusion led to massive leukocyte adhesion and sequestration within reperfused microvessels. Our studies revealed platelets enhanced leukocyte adhesion to endothelial cells, but suppressed leukocyte transendothelial migration. Overall, this leads to leukocyte sequestration in hypoxia-reoxygenated microvessels. | Senfeng Zheng Yanting Cao Wenjian Zhang Honglin Liu Jia You Yiqing Yin Jinning Lou Chenghui Li | 2016 | Science China(Life Sciences)2016，59，3： | 3 |
| 9 | Insight into selective removal of copper from high-concentration nickel solutions with XPS and DFT:New technique to prepare 5N-nickel with chelating resin显示文摘An efficient and profitable separation process was proposed to prepare 5N(the purity of the metal solution reaches 99.999%) high-purity nickel from 3N nickel-solutions using Purolite S984. The adsorption performance of this superior resin, especially its selectivity for metal ions,was explored quantitatively. The maximum adsorption capacity for copper was 2.286 mmol/g calculated by the Langmuir model, which was twice as large as that for nickel. In the binary systems, the adsorption capacity for nickel was decreased by 45%, indicating direct competition for the active sites. The infinite separation factor for copper versus nickel exceeded 300, revealing the feasibility of preparing5N-level high-purity nickel solutions, which was further verified using the 800 BV(bed volume) effluent in the column dynamic process.According to the cost–benefit analysis, purification contributed to a profit of approximately 60,000 USD per cycle, and the investment return period was less than 1/3 years. Density functional theory analysis confirmed that four nitrogen atoms would be involved in the coordination complex and thus a structure involving two five-membered rings could be achieved. The X-ray photoelectron spectra confirmed the involvement of nitrogen atoms,implying a coordination ratio of approximately 1:1. | Xuewen Tao Fuqiang Liu Zhiping Bai Dongyang Wei Xiaopeng Zhang Junfei Wang Jie Gao Xiaowen Sun Baohua Li Chenghui Li Aimin Li | 2016 | Journal of Environmental Sciences2016，28，10： | 3 |
| 10 | Structure regulation for ultra-high luminescence quantum yield lanthanide complex and simultaneous detection of cancer marker and ferrous ion显示文摘The exploitation of a highly selective and sensitive probe to detect both cancer marker and metal ion is of great importance.In this work,the 'one stone two bird' agent of 1,10-phenanthroline(phen) is designed to disrupt the polymeric lanthanide MOFs(LnMOFs,[Ln(CHO_(2))_(3)]n,Ln=Tb,la;Eu,1 b,CHO_(2)=formic acid) {[Ln(CHO_(2))_(4)·(C_(2) H_(8) N)]n,Ln=Y,2 a;Gd,2 b;Dy,2 c,C_(2)H_(8) N=dimethylamine}) into a soluble mononuclear species [Ln(phen)_(2)(NO_(3))_(3),Ln=Tb,3 a;Eu,3 b] as well as to provide an antenna for efficient photons absorption,resulting in an ultra-high luminescence quantum yield(QY,90%) europium complex.The luminescence QY is among the highest record of monomeric(zero-dimensional) lanthanide complexes.Furthermore,mononuclear Tb3+complex(3 a) functions as a multiplex sensor towards both Fe^(2+)and cancer marker of 5-hydroxyindole-3-acetic acid(5-HIAA).Importantly,the limit of detection(LOD)for sensing 5-HIAA is an ultra-sensitive value of 1 × 10 s mol/L,which is even lower than that necessary for the early diagnosis of carcinoid tumors.More interestingly,sensing results in simulated urine reveals that 3 a has potential application for early diagnosis in the clinic. | Min Liu Zhifeng Li Jianhui Xiong Yefei Jiang Ting Tang Jinkai Qiu Junwei Yao Seik Weng Ng Chenghui Zeng | 2021 | Journal of Rare Earths2021，39，10： | 3 |
| 11 | Three-dimensional finite element analysis of shallow indentation of rough strain-hardening surface显示文摘Three-dimensional finite element modeling of the contact between a rigid spherical indenter and a rough surface is presented when considering both the loading and unloading phases. The relationships among the indentation load, displacement, contact area, and mean contact pressure for both loading and unloading are established through a curve fitting using sigmoid logistic and power law functions. The contact load is proportional to the contact area, and the mean contact pressure is related to the characteristic stress, which is dependent on the material properties. The residual displacement is proportional to the maximum indentation displacement. A proportional relationship also exists for plastically dissipated energy and work conducted during loading. The surface roughness results in an effective elastic modulus calculated from an initial unloading stiffness several times larger than the true value of elastic modulus. Nonetheless, the calculated modulus under a shallow spherical indentation can still be applied for a relative comparison. | Chenghui GAO Henry PROUDHON Ming LIU | 2019 | Friction2019，7，6： | 2 |

| 14 | A Preliminary Review of Metallogenic Regularity of Tin Deposits in China显示文摘China is rich in tin resources,and contains many types of tin deposits.Among the tin deposit types,the cassiterite-sulfide type,skarn type and quartz vein type occupy a large proportion of tin resources and reserves.From the aspect of exploitation and utilization,the most important types are cassiterite-sulfide type and quartz vein type.The cassiterite-sulfide type tin deposits are mainly located in Northern Guangxi and Eastern Yunnan,skarn type deposits are mainly distributed in the ore-concentration areas of South Hunan in Middle Nanling,and the quartz vein type tin deposits are mainly distributed in South China,such as Western Fujian,Middle Jiangxi,Northern Guangzhou and Southern Hunan.The most important metallogenic epoch for tin deposits is the Mesozoic era.The metallogenic geotectonic background is mainly continental environments after orogeny process,with strong tectonic changes,interlaced deep fracture and frequent magmatism.And the most distinctive feature is the well developed Mesozoic granites,which have a close relationship with tin mineralization.Based on the detailed study of the data from 873 tin deposits in China,this paper summarized the metallogenic regularity of tin deposits,classified 20 important metallogenic series of tin or tin-associated deposits,and inferred that the cassiterite-sulfide type,skarn type,quartz vein type and greisen type are the main prediction types of tin resources.Forty-four tin-mineralization belts were divided,among which,19 belts are the most important.In addition,a series of maps about tin metallogenic belts and tin metallogenic regularity were compiled,aiming to provide theoretical basis for potential estimation and prediction of tin mineral resources. | CHEN Zhenghui SHENG Jifu LIU Lijun WANG Denghong LIANG Ting WANG Chenghui | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 1 |
| 15 | Influencing factors and growth state classification of a natural Metasequoia population显示文摘By analyzing the importance of influencing factors and conducting a comparative study of the effects of different sorting algorithms, a new method is proposed that is suitable for classifying the growth state of a natural Metasequoia glyptostroboides Hu and W.C. Cheng population. We studied 2817 M. glyptostroboides trees over 100 years old and analyzed their growth state by measuring 15 factors from stumpage, site condition, and environmental data. The dimensionality of all factors were reduced using the random forest algorithm, and we classified the remaining factors using the following algorithms: random forest, back-propagation(BP) neural networks, and support vector machine(SVM). The applicability of each sorting algorithm was analyzed. When all the d factors are used for classification and modeling, the model's overall accuracy,kappa coefficient and test accuracy were 85.5%, 0.739 and 85.8%, respectively. By reducing the dimensionality of the factors using the random forest algorithm, 11 factors most strongly influenced the classifications of the growth state of the Metasequoia population: diameter at breast height,height, crown width, age from stumpage data; longitude,latitude, elevation, slope aspect, gradient and slope position from the site condition data; and the edge of the field from the environmental data. For classifying the Metasequoia population, the random forest algorithm has the highest overall accuracy at 87.2%, which is 3.4 and 2.3% higher than the BP neural networks and SVM algorithms,respectively. The SVM algorithm is superior to the random forest algorithm with respect to classifying the state of mortality. The combination of the random forest and SVM algorithms and their combined information can be used to classify and predict the growth state of this natural M.glyptostroboides population to provide a scientific basis for its effective protection. | Mu Liu Zhongke Feng Chenghui Ma Liyan Yang | 2019 | Journal of Forestry Research2019，30，1： | 1 |
| 16 | Highly sensitive luminescent lanthanide metal-organic framework sensor for L-kynurenine显示文摘L-kynurenine(L-kyn)is a marker of prostate cancer.At present,the expensive instruments are usually applied to detect L-kyn clinically,which limits its wide application for cancer diagnosis.Herein,three lanthanide metal-organic frameworks([Ln(CHO_(2))_(3)]_(n),Ln=Eu,Gd,and Tb)were designed and obtained,and detailly characterized by single crystal X-ray diffraction(SCXRD),powder X-ray diffraction(PXRD),Fourier transform infrared spectroscopy(FT-IR),thermogravimetric analysis(TGA),and luminescence spectroscopy.Further study reveals that[Tb(CHO_(2))_(3)]_(n)is a highly selective,ultra-sensitive,of strong anti-interference,highly stable,and non-expensive sensor for prostate cancer marker L-kyn.The limit of detection(LOD)for L-kyn sensing is a highly sensitive value of 1.0×10^(−9)mol/L.Furthermore,the sensing mechanism is discussed in detail. | Ting Tang Min Liu Zhao Chen Xingxiang Wang Chunguang Lai Liwen Ding Chenghui Zeng | 2022 | Journal of Rare Earths2022，40，3： | 1 |
| 17 | Target Extension-Activated DNA Walker on Nanoparticles for Digital Counting-Based Analysis of MicroRNA显示文摘MicroRNAs(miRNAs),especially exosomal miRNAs,are promising noninvasive biomarkers in early-stage cancer diagnosis and disease treatment monitoring.However,their precise and sensitive quantification remains challenging due to their small size and low abundance.Herein,we have developed a nanoparticle-confined DNA walker strategy for the specific detection of miRNA.In the existence of the target miRNA;the on-particle DNA walking reaction will be initiated,providing a fluorescence-positive nanoparticle.Otherwise,the nanoparticle would be fluorescence-negative.Utilizing the total internal reflection fluorescent microscope(TIRFM)to digitally count the fluorescence-positive nanoparticles,the proposed method possesses a detection limit of 0.2 pmol/L miRNA and can accurately distinguish the single-base mismatched target.This design combines the merits of the DNA walker for signal amplification and the TIRFM for highly sensitive detection,paving a new way for the digital counting-based analysis of exosomal miRNAs. | Qinya Feng Yuqing Zhai Wei Ren Chenghui Liu | 2021 | Chinese Journal of Chemistry2021，39，6： | 1 |
