| 1 | Geochemical characteristics and formation process of natural gas in Kela 2 gas field显示文摘On the basis of a large amount of natural gascomponents and the carbon isotope as well as some otheranalysis data in Kela 2 gas field, the geochemical character-istics, source, origin, and formation process of natural gashave been discussed. The components of gas in the field tendto be 'dry', and the drying coefficient is close to 1.0. Thecarbon isotope tends to be heavier, for instance, the averageof δ13C1 is -27.36‰ and that ofδ13C2 is -18.5‰. Compre-hensive analysis shows that humic natural gas in the Kuqapetroleum system comes mainly from Triassic and Jurassicsource rocks, and the contribution of Jurassic source rocks tothe pool maybe is more than that of Triassic rocks. The maincause that the gas tends to be dry and bears heavier isotopecomposition lies in the fact that Kela 2 natural gas is the ac-cumulation of late production of humic source rocks, and itis affected by the abnormal high pressure as well. Consider-ing the hydrocarbon generating and structural history, wecan regard the gas pool formation processes as twice fillingand twice adjusting (destroying), that is, the filling anddestroying process in the early Himalayan movement and thefilling and adjusting in the late Himalayan movement. | ZHAO Mengjun LU Shuangfang WANG Tingdong LI Jian | 2002 | Chinese Science Bulletin2002，47，S1： | 20 |
| 2 | The historical and current research progress on jujube–a superfruit for the future显示文摘Jujube(Ziziphus jujuba Mill.),or Chinese date,is the most important species of Rhamnaceae,a large cosmopolitan family,and is one of the oldest cultivated fruit trees in the world.It originates from the middle and lower reaches of the Yellow River,the‘mother river’of the Chinese people.It is distributed in at least 48 countries on all continents except Antarctica and is becoming increasingly important,especially in arid and semiarid marginal lands.Based on a systematic analysis of the unique characteristics of jujube,we suggest that it deserves to be recognized as a superfruit.We summarized historical research achievements from the past 3000 years and reviewed recent research advances since 1949 in seven fields,including genome sequencing and application,germplasm resources and systematic taxonomy,breeding and genetics,cultivation theory and techniques,pest control,postharvest physiology and techniques,and nutrition and processing.Based on the challenges facing the jujube industry,we discuss eight research aspects to be focused on in the future. | Mengjun Liu Jiurui Wang Lili Wang Ping Liu Jin Zhao Zhihui Zhao Shengrui Yao Florin Stănică Zhiguo Liu Lixin Wang Changwei Ao Li Dai Xiansong Li Xuan Zhao Chunxiang Jia | 2020 | Horticulture Research2020，7，1： | 10 |
| 3 | Control of neotectonic movement on hydrocarbon accumulation in the Kuqa Foreland Basin,west China显示文摘Neotectonic movement refers to the tectonic movement that has happened since the Cenozoic,which is the latest movement. It has the most important influence on the basins in west China,especially on the hydrocarbon accumulation in the western foreland basins. We determined the time of neotectonic movement in the Kuqa Foreland Basin,which began from the Neogene,and analyzed the patterns of movement,which were continuous and fast subsidence in the vertical direction and intense lateral compression. The structure styles are that the faulting is weakened and the folding is strengthened gradually from north to south. We studied the control of neotectonic movement on the hydrocarbon accumulation process and model in the Kuqa Foreland Basin with basin simulation technique. The largest subsidence rate of the Kuqa Foreland Basin reached 1,200 m/Ma during the neotectonic movement,leading to rapid maturing of source rock within 5 Ma and a large quantity of hydrocarbon being generated and expelled. The thick neotectonic strata can form high quality reservoirs with the proved gas and oil reserves accounting for 5% and 27% of the total reserves,respectively. 86% of the structural traps were formed in the neotectonic movement period. The faults formed during the neotectonic movement serve as important migration pathways and they exist in the region where the hydrocarbon reservoirs are distributed. Abnormally high pressure caused by the intense lateral compression,thick neotectonic strata deposition and rapid hydrocarbon generation provide driving force for hydrocarbon migration. The accumulation elements match each other well over a short period,leading to many large gas fi elds formed later in the Kuqa Foreland Basin. | Jiang Zhenxue Li Lianxia Song Yan Tian Fenghua Zhao Mengjun Wang Haijiang Zhao Zhenxing | 2010 | Petroleum Science2010，7，1： | 6 |
| 4 | In Vivo Fast Induction of Homogeneous Autopolyploids via Callus in Sour Jujube(Ziziphus acidojujuba Cheng et Liu)显示文摘Polyploidization has been demonstrated as a very effective approach in fruit tree improvement.Sour jujube(Ziziphus acidojujuba Cheng et Liu) is a promising diploid wild,traditional fruit species(2n = 2x = 24) that is rich in vitamin C,which is the main rootstock of Chinese jujube(Z.jujuba Mill.).The novel method we developed for rapid in vivo induction of homogeneous autopolyploids(IVIHA) via callus in Chinese jujube was first applied and further optimized in sour jujube.Under optimized conditions,an average of one pure autotetraploid shoot could be regenerated from one treated branch,thereby indicating a relatively high efficiency rate.A total of 9 pure autotetraploid genotypes were created,and one of these was released as a new cultivar named ‘Zhuguang' in 2015.Moreover,unexpected octoploids and hexaploids were also simultaneously created and detected.The leaves of tetraploids were thicker,broader,and darker in color than those of the original diploids,whereas the leaf sizes of octoploids were much smaller compared to that of diploids.However,stoma size increased with the occurrence of ploidy,mainly from diploid to octoploid.The well grown ploidies of jujube included diploids,triploids,and tetraploids.Anatomical observation indicated that adventitious buds/shoots emerged from the callus that formed on the cut,which was then followed by the development of connective vascular tissues between the adventitious bud and the stock plant tissue.This study demonstrates the universality of the IVIHA method that was initially developed in Chinese jujube,as well as provides a foundation for high-efficiency pure polyploid induction in sour jujube. | SHI Qinghua LIU Ping LIU Mengjun WANG Jiurui ZHAO Jin ZHAO Zhihui DAI Li | 2016 | Horticultural Plant Journal2016，2，3： | 5 |

| 6 | Differentially Private Spatial Decompositions for Geospatial Point Data显示文摘Technological advancements in data analysis and data releasing have put forward higher security requirements, such as privacy guarantee and strictly provable security, this new area of research is called differential privacy. As for geospatial point data, the exiting methods use the tree structure to split the data space to enhance the data utility and usually adopt uniform budgeting method. Different from this, we propose a novel non-uniform allocation scheme for privacy budget which is a parameter to specify the degree of privacy guarantee. Firstly, the spatial data is indexed by quadtree, then, different privacy budget is allocated to each layer of quadtree using Fibonacci series features, and we designate this budgeting method as Fibonacci allocation. Experimental results show that Fibonacci allocation is significantly more accurate in data queries than the state-of-the-art methods under the same privacy guarantee level and fits for arbitrary range queries. Furthermore, data utility can be improved by post-processing and threshold determination. | WANG Jun LIU Shubo LI Yongkai CAO Hui LIU Mengjun | 2016 | China Communications2016，13，4： | 5 |
| 7 | Characteristics,genesis and accumulation history of natural gas in Hetianhe gasfield,Tarim Basin,China显示文摘Hetianhe gasfield in Bachu region of the Tarim Basin is mainly composed of three reservoir-caprock assembly,namely regional caprock of upper mudstone,middle mudstone and lower mudstone of the Carboniferous and reservoir of Bachu bioclastic limestone,glutenite and the Ordovician carbonate buried hill.Natural gas in Hetianhe gasfield sourced from the Cambrian source rock.It is thought that gases in Ma4 well block in the east of Hetianhe gasfield are mainly crude-oil cracked gases,while those in Ma3 and Ma8 well blocks in the west are the mixture gases of kerogen cracked gases and crude-oil cracked gases.Natural gas is rich in H2S and accumulated in multiply stages as the result of TSR.The accumulation history is divided into three stages,namely accumulation and breakage in the late Caledonian-early Hercynian,migration and dissipation in the late Hercynian and accumulation in Himalayan. The main accumulation of reformed gas reservoir is in Himalayan. | WANG ZhaoMing 1 ,WANG QingHua 1 ,ZHAO MengJun 2 ,LI Yong 1 &XU ZhiMing 3 1 Tarim Oilfield Company,PetroChina,Kuerle 841000,China 2 Research Institute of Petroleum Exploration&Development,PetroChina,Beijing 100083,China 3 Southwest Petroleum Institute,Nanchong 637001,China | 2008 | Science China Earth Sciences2008，51，S1： | 4 |
| 8 | Privacy-preserving Distributed Location Proof Generating System显示文摘The rapid development of location-based service(LBS) drives one special kind of LBS, in which the service provider verifies user location before providing services. In distributed location proof generating schemes, preventing users from colluding with each other to create fake location proofs and protecting user's location privacy at the same time, are the main technical challenges to bring this kind of LBS into practical. Existing solutions tackle these challenges with low collusion-detecting efficiency and defected collusion-detecting method. We proposed two novel location proof generating schemes, which inversely utilized a secure secret-sharing scheme and a pseudonym scheme to settle these shortcomings. Our proposed solution resists and detects user collusion attacks in a more efficient and correct way. Meanwhile, we achieve a higher level of location privacy than that of previous work. The correctness and efficiency of our proposed solution is testified by intensive security analysis, performance analysis, as well as experiments and simulation results. | LIU Mengjun LIU Shubo ZHANG Rui Li Yongkai WANG Jun CAO Hui | 2016 | China Communications2016，13，3： | 3 |
| 9 | Life Prediction Based on Transient Dynamics Analysis of Van Semi-trailer with Air Suspension System显示文摘The early fatigue damage in the van-body of the semi-trailer is often caused by the unique mechanical characteristics and the dynamic impact of the loads.The traditional finite element method with static strength analysis cannot support the fatigue design of van-body;thus,the dynamics analysis should be adopted for the endurance performance.The accurate dynamics model to describe the transient impacts of all kinds of uneven road and the proper system transfer functions to calculate the load transfer effects from tire to van-body are two critical factors for transient dynamics analysis.In order to evaluate the dynamic performance,the dynamics model of the trailer with the air suspension is brought forward.Then the analysis method of the power spectral density (PSD) is set up to study the transient responses of the road dynamic impacts.The transient responses transferred from axles to van-body are calculated,such as dynamic stress,dynamic RMS acceleration,and dynamic load factors.Based on the above dynamic responses,the fatigue life of van-body is predicted with the finite element analysis (FEA) method.Applying the test parameters of the trailer with air suspension,the simulation system with Matlab/Simulink is constructed to describe the dynamic responses of the impacts of the tested PSD of the vehicle axles,and then the fatigue life is predicted with FEA method.The simulated results show that the vibration level of the van-body with air suspension is reduced and the fatigue life is improved.The real vehicle tests on different roads are carried out,and the test results validate the accuracy of the simulation system.The proposed fatigue life prediction method is effective for the virtual design of auto-body. | LI Liang SONG Jian HE Lin ZHANG Mengjun LI Hongzhi | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 3 |
| 10 | The regulatory pathways of distinct flowering characteristics in Chinese jujube显示文摘Flowering is the most important event in higher plants.Compared to most fruit tree species,Chinese jujube(Ziziphus jujuba Mill.),the most important member of the large,diverse Rhamnaceae family and a leading dry fruit-producing species,has unique characteristics that include a short juvenile phase and extremely fast flower bud differentiation.However,the distinct mechanism of flowering regulation in Chinese jujube is still unclear.The morphological and cytological development period of jujube flowering was first investigated,and the crucial developmental stages were defined.Flower bud differentiation in Chinese jujube took only approximately 11–13 days,which is a distinct characteristic of perennial fruit trees.Afterward,44 genes related to six flowering pathways were identified in the jujube genome and were found to be randomly distributed among 11 of the 12 chromosomes.Tissue-specific and spatiotemporal expression patterns showed that all these genes were expressed in the flowers.Overall,photoperiodrelated genes were highly expressed during flower bud differentiation.These genes were also positively responsive to photoperiod regulation and phase change processes,indicating that photoperiod-related genes play crucial roles in jujube flower bud differentiation.Under protected cultivation,ZjPIF4,a temperature-related gene,was expressed in the early stages of flowering and responded to increasing temperatures.Moreover,STRING analysis and yeast two-hybrid screening indicated that photoperiod-related(ZjCO)and temperature-related(ZjPIF4)proteins could interact with ZjFT,the key protein involved in the determination of flowering time,indicating crosstalk between photoperiodrelated pathways and ambient temperature-related pathways in jujube.This study is the first report to comprehensively analyze the flowering pathways in Chinese jujube and revealed that photoperiod-related and ambient temperature-related pathways are the main mechanisms regulating the distinct flowering process and that members of the ZjPHY family(ZjPIF4,ZjFT,and ZjCO5)are the key factors involved in the regulatory network.These results will increase our understanding of the molecular and genetic mechanisms of flowering in Chinese jujube and provide meaningful clues for the flowering regulation of other fruit tree species. | Xianwei Meng Ying Li Ye Yuan Yao Zhang Hongtai Li Jin Zhao Mengjun Liu | 2020 | Horticulture Research2020，7，1： | 3 |
| 11 | Cell outage compensation based on Co MP and optimization of tilt显示文摘Cell outage compensation(COC) is a self-healing function of the self-organizing networks(SONs) concept for mobile wireless networks. In order to compensate the outage cell autonomously, this paper drives a solution for COC. This method is based on coordinated multiple points(Co MP) transmission and tilt adjusting. Firstly, the paper takes the coordinated pattern and tilt as the optimization objects. Then, it defines the rational objectives and the evaluation function of the situation and analysis the optimization model. Finally, based on the effective genetic algorithm(GA), the compensation mechanism is proposed. Simulation results show that this solution is better than the elder solutions in terms of coverage, interference, and throughput. | Yin Mengjun Feng Lei Li Wenjing Yu Peng Qiu Xuesong | 2015 | The Journal of China Universities of Posts and Telecommunications2015，22，5： | 3 |
| 12 | Features of the type Ill-like source rock and its generated natural gas显示文摘The mother matter of Ordovician source are mainly sapropelic and generate oil in mature stage, since the high plants did not appear in Ordovician period, which is well known by internal and external scholars. Now we find a kind of Orodovician source rock generating mainly light oil and gas in mature stage during appraising source rocks in the Tarim Basin. The organic matters of this source rock are chiefly constructed by benthic brown algae in organisms (showing as macro algae), and are similar to humic source in hydrocarbon generation. The natural gas generated by this kind of source matters is obviously different from the sapropelic gas. | ZHAO Mengjun, ZHANG Baomin, BIAN Lizeng, XIAO Zhongyao, LI Mei, PENG Yan & QIN Shengfei1.

| 13 | Applying generalized hydrophobicity scale of amino acids to quantitative prediction of human leukocyte antigen-A~*0201-restricted cytotoxic T lymphocyte epitope显示文摘Derived from 149 hydrophobic factors of 20 natural amino acids, a novel amino acid descriptor termed as generalized hydrophobicity scale (GH-scale) was proposed by principal component analysis (PCA). Via genetic algorithm-partial least square (GPLS) method, quantitative structure-activity relationship (QSAR) model was constructed by GH-scale for 152 human leukocyte antigen (HLA)-A*0201-restricted cytotoxic T lymphocyte (CTL) epitopes with the model estimated and cross-validated correlative coefficients of R2 = 0.813 and Q2 = 0.725, respectively. It was in- dicated that hydrophobic interaction played an im- portant role in HLA-A*0201-CTL interaction, promi- nently at anchor residues. | ZHOU Peng TIAN Feifei ZHANG Mengjun LI Zhiliang | 2006 | Chinese Science Bulletin2006，51，12： | 2 |
| 14 | A novel vector of topological and structural information for amino acids and its QSAR applications for peptides and analogues显示文摘A new descriptor, called vector of topological and structural information for coded and noncoded amino acids (VTSA), was derived by principal component analysis (PCA) from a matrix of 66 topological and structural variables of 134 amino acids. The VTSA vector was then applied into two sets of peptide quantitative structure-activity relationships or quantitative sequence-activity modelings (QSARs/ QSAMs). Molded by genetic partial least squares (GPLS), support vector machine (SVM), and immune neural network (INN), good results were obtained. For the datasets of 58 angiotensin converting en-zyme inhibitors (ACEI) and 89 elastase substrate catalyzed kinetics (ESCK) , the R2, cross-validation R2, and root mean square error of estimation (RMSEE) were as follows: ACEI, R2cu≥0.82, Q2cu≥0.77, Ermse≤0.44 (GPLS+SVM); ESCK, R2cu≥0.84, Q2cu≥0.82, Ermse≤0.20 (GPLS+INN), respectively. | LI ZhiLiang LI GenRong SHU Mao SUN JiaYing YANG ShanBin MEI Hu ZHANG MengJun ZHOU Ping WU ShiRong CHEN GuoHua LU FengLin LU TingTing | 2008 | Science China Chemistry2008，51，10： | 2 |
| 15 | Design and heat transfer analysis of a compound multi-layer insulations for use in high temperature cylinder thermal protection systems显示文摘Thermal protection systems are very essential for high temperature thermal conductivity measurement system to reduce the heat loss to environment at the range of 600–1800 K. A compound multi-layer insulations structure which composed of inner carbon fibrous materials and outer alternately arranged alumina fibrous materials and high reflectivity foils is proposed for use in high temperature cylinder thermal protection systems. A coupled conductive and radiation governing equations is presented for heat transfer analysis of the structure. The finite volume method and the discrete ordinate method are used to solve the governing equations. The optimization structure of the compound multi-layer insulations is investigated by considering the pressure of the gas, the density of the carbon fibrous materials, the density of the alumina fibrous materials, the number of reflective foil layers and the emissivity of reflective foils. The results show that the compound structure has the best thermal insulation performance when the pressure of the gas is below 0.01 k Pa, the density of carbon fibrous materials is 180 kg m^(-3), the density of alumina fibrous materials is 256 kg m^(-3) and the number of reflective foil layers is 39. In addition, the thermal insulation performance is much better when the emissivity of reflective foils is lower. | CHEN MengJun ZHANG Ping LI Qiang | 2018 | Science China(Technological Sciences)2018，61，7： | 2 |
| 16 | Super-absorbent swellable polymer as grouting material for treatment of karst water inrush显示文摘Grouting is the most commonly used method to control water inrush in underground engineering.Traditional cement-based materials are easy to dilute and hard to coagulate under the influence of large flow and high-velocity water inrush.To address these deficiencies,a new type of polymer grouting material with an excellent expansion ratio was synthesised.The material quickly absorbs water and has an expansion ratio of 1:300.The material is composed of a superabsorbent polymer(SAP),glycerol,and ethanol.The effects of water quality on the expansion ratio and expansion rate of the material were examined,and the best solid–liquid ratio for the slurry was determined by fluidity measurements.A karst specially designed pipeline water inrush test device showed that 800 g of SAP can achieve 0.6 m/s water flow blockage in the smooth pipeline,demonstrating that the ability of the SAP slurry to block water inrush is superior to those of other materials.This study provides a reference for water inrush plugging,and has important implications for the reduction and control of karst pipeline-type water inrush disasters,ensuring the safety of construction sites and preventing loss of life and damage to property. | Shucai Li Chenyang Ma Rentai Liu Mengjun Chen Jia Yan Zhenjun Wang Shaolong Duan Huasheng Zhang | 2021 | International Journal of Mining Science and Technology2021，31，5： | 2 |
| 17 | Enhanced weathering input from South Asia to the Indian Ocean since the late Eocene显示文摘nhanced silicate weathering induced by the uplift of the Himalayan-Tibetan Plateau(HTP)has been considered as the major cause of pCO_(2) decline and Cenozoic cooling.However,this hypothesis remains to be validated,largely due to the lack of a reliable reconstruction of the HTP weathering flux.Here,we present a 37-million-year record of the difference in the seawater radiogenic neodymium isotopic composition(△ε_(Nd))of Ocean Drilling Program(ODP)sites and Fe-Mn crusts between the northern and central Indian Ocean,which indicates the contribution of regional weathering input from the South Asian continent to the Indian Ocean.The results show a long-term increase in △ε_(Nd) and thus provide the first critical evidence of enhanced South Asian weathering input since the late Eocene.The evolution coincided well with major pulses of surface uplift in the HTP and global climatic transitions.Our foraminiferal eNd record suggests that tectonic uplift and silicate weathering in South Asia,especially in the Himalayas,might have played a significant role in the late Cenozoic cooling. | Zehua Song Shiming Wan Christophe Colin Christian France-Lanord Zhaojie Yu Arnaud Dapoigny Hualong Jin Mengjun Li Jin Zhang Debo Zhao Xuefa Shi Anchun Li | 2023 | Science Bulletin2023，，3： | 2 |
| 18 | Differential Hydrocarbon Accumulation Controlled by Structural Styles along the Southern and Northern Tianshan Thrust Belt显示文摘The Kuqa and the Southern Junggar foreland thrust belts, which lie to the southern and northern Tianshan, respectively, were formed under a strong compressional tectonic setting. Due to the differential propagation and deformation under the control of the décollement horizon, the structural deformation styles differ in the Kuqa and Southern Junggar thrust belts. Imbricated stacking is developed in the Kuqa thrust belt, forming a piggyback imbricated pattern of faulted anticline and fault-block structural assemblage dominated by salt structures. In contrast, wedge-shaped thrusts are developed in Southern Junggar, mainly forming vertical laminated patterns of multi-wedge-structure stacks strongly influenced by the décollement horizons. The different deformation patterns and structural styles of the north and south of Tian Shan control the contrasting characteristics of hydrocarbon accumulation in the foreland thrust belts of the Kuqa and the Southern Junggar thrust belts, including the variance in the hydrocarbon trap types, pathway systems and hydrocarbon-bearing horizons. Proven by the hydrocarbon accumulation research and exploration achievements, recent exploration targets should focus on sub-salt piggyback imbricated structural patterns in the Kuqa and the deep laminated patterns in the Southern Junggar thrust belt. | SONG Yan ZHAO Mengjun FANG Shihu LI Benliang LIU Shaobo ZHUO Qingong | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 2 |
