| 1 | De novo assembly of a Chinese soybean genome显示文摘Soybean was domesticated in China and has become one of the most important oilseed crops. Due to bottlenecks in their introduction and dissemination, soybeans from different geographic areas exhibit extensive genetic diversity. Asia is the largest soybean market; therefore, a high-quality soybean reference genome from this area is critical for soybean research and breeding.Here, we report the de novo assembly and sequence analysis of a Chinese soybean genome for 'Zhonghuang 13' by a combination of SMRT, Hi-C and optical mapping data. The assembled genome size is 1.025 Gb with a contig N50 of 3.46 Mb and a scaffold N50 of 51.87 Mb. Comparisons between this genome and the previously reported reference genome(cv. Williams82) uncovered more than 250,000 structure variations. A total of 52,051 protein coding genes and 36,429 transposable elements were annotated for this genome, and a gene co-expression network including 39,967 genes was also established. This high quality Chinese soybean genome and its sequence analysis will provide valuable information for soybean improvement in the future. | Yanting Shen Jing Liu Haiying Geng Jixiang Zhang Yucheng Liu Haikuan Zhang Shilai Xing Jianchang Du Shisong Ma Zhixi Tian | 2018 | Science China(Life Sciences)2018，61，8： | 11 |
| 2 | Dispositional characteristics of Ordovician Wufeng Formation and Silurian Longmaxi Formation in Sichuan Basin and its adjacent areas显示文摘According to data of gas wells and typical sections of Wufeng Formation and Longmaxi Formation in Sichuan Basin,shale of various graptolite zones were analyzed to determine depositional environment,lithology and thickness characteristics of the graptolite shale interval of WF2-WF3 in the lower part of Wufeng Formation,the graptolite shale interval of WF4 in Guanyinqiao Member of Wufeng Formation and the graptolite shale interval of LM1-LM4 in the bottom of Longmaxi Formation,and characteristics of shale horizontal distribution were also investigated.During the depositional period of the graptolite shale interval of WF2-WF3,the study area was less affected by the Guangxi movement,the depositional environment was the deep water of open sea,where black shale was mainly deposited;the sedimentation center was developed in northeast Guizhou-northeast Sichuan and south Sichuan,the maximum thickness was from 4 to 6 m in the sedimentation center.During the depositional period of the graptolite shale interval of WF4,the depositional environment in the study area changed greatly due to global sea level fall and enhanced Guangxi movement;the central Sichuan paleouplift,the central Guizhou paleouplift and the Jiangnan-Xuefeng palaeouplift were further expanded,and the area of the sedimentary basin decreased;the depositional environment was mainly carbonate bioclastic shoal of shallow sea,and partially deep sea which only was distributed in the Shizhu-Fuling-Wuxi area in east and northeast Sichuan and the Gongxian-Yongchuan area in south Sichuan;sediments of shallow water were dominated by limestone and argillaceous limestone with abundant Hirnantia,sediments of deep water were dominated by calcareous mudstone and shale with Hirnantia.During the depositional period of the graptolite shale interval of LM1-LM4,due to rise of global sea level and Guangxi movement,the sedimentary area was larger than that in the depositional period of Guanyinqiao Member,and the sedimentary environment mainly was stagnant deepwater;thickness of black shale in the graptolite shale interval of LM1-LM4 was large,and the maximum thickness was over 20 m.Furthermore,control of the central Sichuan paleouplift,the central Guizhou paleouplift and the Jiangnan-Xuefeng paleouplift on black shale was discussed,and control of the Zhiliujing underwater highland/uplift,Huayingshan highland and Dingshan highland as well as western Hubei-Hunan underwater highland/uplift on shale deposition and preservation was also investigated. | Haikuan Nie Zhijun Jin Xin Ma Zhongbao Liu Tuo Lin Zhenheng Yang | 2017 | Petroleum Research2017，2，3： | 3 |
| 3 | A new alternating copolymerized derivative as a cold flow improver for diesel fuel显示文摘Synthesis of a cold flow improver(MAVA-a) for diesel fuel and its effect on solidifying point(SP) and cold filter plugging point(CFPP) of diesel fuels were investigated.The cold flow improver was prepared by using maleic anhydride(MA) and vinyl acetate(VA) as raw materials,toluene as solvent,dibenzoyl peroxide(BPO) as initiator,through alternating polymerization under nitrogen to obtain a binary-polymer and then through aminolysis by using a higher carbon amine as aminating agent at a temperature of 80 °C.A cold flow improver was designed and prepared for No.0 diesel fuel from Zhang Jia-Gang Petrochemical Company according to the contents of n-paraffin and its carbon number distribution in the No.0 diesel fuel.It was also used together with two kinds of ethene-vinyl acetate copolymer improvers(EVA) separately.The test result showed that the CFPP of the No.0 diesel fuel could be lowered by 3-5 °C when the improver MAVA-a was used.The CFPP was lowered by 8 °C when the improver MAVA-a was used together with EVA-2. | ZHANG Haikuan LIU Hongyan WANG Shujun | 2009 | Petroleum Science2009，6，1： | 3 |
| 4 | Enrichment characteristics and exploration directions of deep shale gas of Ordovician-Silurian in the Sichuan Basin and its surrounding areas,China显示文摘The enrichment characteristics of deep shale gas in the Ordovician Wufeng-Silurian Longmaxi formations in the Sichuan Basin and its surrounding areas are investigated through experiments under high temperature and high pressure,including petrophysical properties analyses,triaxial stress test and isothermal adsorption of methane experiment.(1)The deep shale reservoirs drop significantly in porosity and permeability compared with shallower shale reservoirs,and contain mainly free gas.(2)With higher deviatoric stress and axial strain,the deep shale reservoirs have higher difficulty fracturing.(3)Affected by structural location and morphology,fracture characteristics,geofluid activity stages and intensity,deep shale gas reservoirs have more complicated preservation conditions.(4)To achieve the commercial development of deep shale gas reservoirs,deepening geological understanding is the basis,and exploring reservoir simulation technology befitting the geological features is the key.(5)The siliceous shale and limestone-bearing siliceous shale in the Metabolograptus persculptus-Parakidograptus acuminatus zones(LM1-LM3 graptolite zones)are the high-production intervals for deep shale gas and the most favorable landing targets for horizontal drilling.Deeps water areas such as Jiaoshiba,Wulong,Luzhou and Changning with deep shale reservoirs over 10 m thickness are the most favorable areas for deep shale gas enrichment.It is recommended to carry out exploration and development practice in deep-water shale gas areas deposited deep with burial depth no more than 5000 m where the geological structure is simple and the shale thickness in the LM1-LM3 graptolite zone is greater than 10 m.It is better to increase the lateral length of horizontal wells,and apply techniques including high intensity of perforations,large volume of proppant,far-field and near-wellbore diversions to maximize the stimulated deep reservoir volume. | NIE Haikuan LI Pei DANG Wei DING Jianghui SUN Chuanxiang LIU Mi WANG Jin DU Wei ZHANG Peixian LI Donghui SU Haikun | 2022 | Petroleum Exploration and Development2022，49，4： | 3 |
| 5 | Experimental Research on the Physical and Mechanical Properties of Concrete with Recycled Plastic Aggregates显示文摘In order to study the effect of recycled plastic particles on the physical and mechanical properties of concrete,recycled plastic concrete with 0,3%,5%and 7%content(by weight)was designed.The compressive strength,splitting tensile strength and the change of mass caused by water absorption during curing were measured.The results show that the strength of concrete is increased by adding recycled plastic into concrete.Among them,the compressive strength and the splitting tensile strength of concrete is the best when the plastic content is 5%.With the increase of plastic content,the development speed of early strength slows down.Silane coupling agent plays a positive role in the strength of recycled plastic concrete.The water absorption saturation of concrete has been basically completed in the early stage.The addition of silane coupling agent makes the porosity of concrete reduce and the water absorption of concrete become poor.By summing up the physical and mechanical properties of recycled plastic concrete,it could be found that the addition of recycled plastic was effective for the modification of concrete materials.Under the control of the amount of recycled plastic,the strength of concrete with recycled plastic aggregates can meet the engineering requirements. | Haikuan Wu Changwu Liu Song Shi Kangliang Chen | 2020 | Journal of Renewable Materials2020，8，7： | 2 |

| 7 | Geochemistry, Petrology and Mineralogy of Coal Measure Shales in the Middle Jurassic Yanan Formation from Northeastern Ordos Basin, China: Implications for Shale Gas Accumulation显示文摘The Jurassic Yanan Formation is one of the most important coal-producing formations and hydrocarbon source rocks in the Ordos Basin, North China. To evaluate the shale gas potential of the Yanan shale, a total of 48 samples from north Ordos Basin were sampled, and their geochemical, petrological, mineralogical and pore characteristics were investigated. It was found that the shale samples are a suite of early mature source rock. The total organic carbon(TOC) content ranges from 0.33% to 24.12% and the hydrogen index(HI) ranges from 43.31 mg/g to 330.58 mg/g. The relationship between Tmax and HI indicates the organic matter is type Ⅱ-Ⅲ. This conclusion is also supported by the organic petrological examination results, which shows that the kerogen is mainly liptinite and vitrinite. Minerals in the samples are composed mainly of quartz, clay and feldspar, and the clay minerals are composed of prevailing kaolinite, illite/smectite, chlorite and a small amount of illite. Under scanning electron microscope, OM pores in the Yanan shale are scarce except pores come from the kerogen intrinsic texture or clay aggregates within the organic particles. As the weak compaction caused by shallow burial depth, interparticle pores and intraparticle pores are common, the hydrocarbon storage capacity of the Yanan shale was improved. According to evaluation, the Yanan shale is considered as a good shale gas reservoir, but its hydrocarbon potential is more dependent on biogenic and coal-derived gas as the thermogenic gas is limited by the lower thermal maturity. | CHEN Qian YAN Xiangbin GUO Yuanling HONG Taiyuan NIE Haikuan ZHANG Jinchuan TANG Xuan LI Wanjun LIU Chong | 2018 | Acta Geologica Sinica(English Edition)2018，92，6： | 2 |
| 8 | Pore characteristics and formation mechanism of high-maturity organic-rich shale in Lower Cambrian Jiumenchong Formation,southern Guizhou显示文摘In order to investigate pore characteristics and formation mechanism in the high-maturity organic-rich shale of Lower Cambrian Jiumenchong Formation in southern Guizhou,the pore structure,pore type and storage properties are well studied through the rock thin section,total rock X-ray diffraction,lowtemperature nitrogen adsorption,high pressure mercury injection-adsorption test,helium porosity test,argon ion polishing-scanning electron microscope,thermal evolution and pore evolution history reconstruction,and based on the diagenesis and compaction as well as thermal evolution process,a microscopic pore formation and evolution model of high-maturity organic-rich shale are established.The result shows that the high-maturity organic-rich shale of Jiumenchong Formation has the average total specific surface area of 12.66m^(2)/g and the total pore volume of 11.54×10^(-3)cm^(3)/g,and the total specific surface area have a positive correlation with total pore volume;the total specific surface area and the total pore volume are slightly lower compared with the Lower Silurian shale.The pores are dominated by micropores and mesopores,while macropores are very rare.The pores of the organic-rich shale mainly are organic pores with small diameter usually less than 30 nm,and the pore boundary form is irregular,the inorganic mineral pores are not developed.Compared with the Silurian shale,the shale has poorer reservoir property,the average porosity is only 2.80%;the horizontal permeability is 1e3 times of the vertical permeability,indicating the horizontal lamellations are not developed.The formation and evolution of pores in high-maturity organic-rich shale is jointly influenced by the evolutionary process of intergranular pores of inorganic mineral under the control of the diagenesis and compaction,the organic pore formation process in the hydrocarbon generation-oil formation-oil and gas transformation sequence under the control of thermal evolution,and the natural gas loss-supply equilibration process under the condition of later pore preservation. | Zhongbao Liu Bo Gao Zongquan Hu Wei Du Haikuan Nie Tao Jiang | 2018 | Petroleum Research2018，3，1： | 2 |

| 11 | Genomes of 12 fig wasps provide insights into the adaptation of pollinators to fig syconia显示文摘Figs and fig pollinators are one of the few classic textbook examples of obligate pollination mutualism.The specific dependence of fig pollinators on the relatively safe living environment with sufficient food sources in the enclosed fig syconia implies that they are vulnerable to habitat changes.However,there is still no extensive genomic evidence to reveal the evolutionary footprint of this long-term mutually beneficial symbiosis in fig pollinators.In fig syconia,there are also non-pollinator species.The non-pollinator species differ in their evolutionary and life histories from pollinators.We conducted comparative analyses on 11 newly sequenced fig wasp genomes and one previously published genome.The pollinators colonized the figs approximately 66.9 million years ago,consistent with the origin of host figs.Compared with nonpollinators,many more genes in pollinators were subject to relaxed selection.Seven genes were absent in pollinators in response to environmental stress and immune activation.Pollinators had more streamlined gene repertoires in the innate immune system,chemosensory toolbox,and detoxification system.Our results provide genomic evidence for the differentiation between pollinators and nonpollinators.The data suggest that owing to the long-term adaptation to the fig,some genes related to functions no longer required are absent in pollinators. | Jinhua Xiao Xianqin Wei Yi Zhou Zhaozhe Xin Yunheng Miao Hongxia Hou Jiaxing Li Dan Zhao Jing Liu Rui Chen Liming Niu Guangchang Ma Wenquan Zhen Shunmin He Jianxia Wang Xunfan Wei Weihao Dou Zhuoxiao Sui Haikuan Zhang Shilai Xing Miao Shi Dawei Huang | 2021 | Journal of Genetics and Genomics2021，48，3： | 1 |

| 15 | Porosity, permeability and rock mechanics of Lower Silurian Longmaxi Formation deep shale under temperature-pressure coupling in the Sichuan Basin, SW China显示文摘To investigate the porosity, permeability and rock mechanics of deep shale under temperature-pressure coupling, we selected the core samples of deep shale from the Lower Silurian Longmaxi Formation in the Weirong and Yongchuan areas of the Sichuan Basin for porosity and permeability experiments and a triaxial compression and sound wave integration experiment at the maximum temperature and pressure of 120 ℃ and 70 MPa. The results show that the microscopic porosity and permeability change and the macroscopic rock deformation are mutually constrained, both showing the trend of steep and then gentle variation. At the maximum temperature and pressure, the porosity reduces by 34%–71%, and the permeability decreases by 85%–97%. With the rising temperature and pressure, deep shale undergoes plastic deformation in which organic pores and clay mineral pores are compressed and microfractures are closed, and elastic deformation in which brittle mineral pores and rock skeleton particles are compacted. Compared with previous experiments under high confining pressure and normal temperature,the experiment under high temperature and high pressure coupling reveals the effect of high temperature on stress sensitivity of porosity and permeability. High temperature can increase the plasticity of the rock, intensify the compression of pores due to high confining pressure, and induce thermal stress between the rock skeleton particles, allowing the reopening of shale bedding or the creation of new fractures along weak planes such as bedding, which inhibits the decrease of permeability with the increase of temperature and confining pressure. Compared with the triaxial mechanical experiment at normal temperature, the triaxial compression experiment at high temperature and high pressure demonstrates that the compressive strength and peak strain of deep shale increase significantly due to the coupling of temperature and pressure. The compressive strength is up to 435 MPa and the peak strain exceeds 2%, indicating that high temperature is not conducive to fracture initiation and expansion by increasing rock plasticity. Lithofacies and mineral composition have great impacts on the porosity, permeability and rock mechanics of deep shale. Shales with different lithologies are different in the difficulty and extent of brittle failure. The stress-strain characteristics of rocks under actual geological conditions are key support to the optimization of reservoir stimulation program. | SUN Chuanxiang NIE Haikuan SU Haikun DU Wei LU Ting CHEN Yalin LIU Mi LI Jingchang | 2023 | Petroleum Exploration and Development2023，50，1： | 1 |
| 16 | A new sampler for simulating aerosol deposition in the respiratory tract显示文摘For estimation of the deposition fractions of radon progeny in different regions of the respiratory tract, a new sampler consisting of three different configurations of sampling heads was developed. The deposition fractions of aerosols on the wire screens inside the sampling heads were calculated with the fan model of filtration theory. The deposition fractions of aerosols in different regions of the respiratory tract were calculated with the lung dose evaluation program (LUDEP)developed by National Radiological Protection Board (NRPB) as references. In general indoor and mine environments, the deviation between the deposition fractions of attached aerosol on the wire screens designed in this study and its reference values in the respiratory tract is less than 5%. It is possible to accurately estimate the deposition fractions of radon progeny in different regions of the respiratory tract through mimic measurements of radon progeny collected with the new sampler. | LI Dehong ZHUO Weihai YI Yanling CHEN Bo LIU Haikuan | 2008 | Nuclear Science and Techniques2008，19，3： | 0 |
| 17 | Construction of a computational MDCT model for simulations of the detector signals显示文摘Objective:To develop a computational model of a multi-detector CT scanner(MDCT),which could be used to simulate the signal of each detector element in the MDCT by using the Monte Carlo method.Methods:The CT scanner was modelled,including the X-ray source,the bowtie filter,the collimator,the couch and the detector panel.Under a general scanning condition,the signal in each detector element was simulated based on the model by using the MCNPX code.Both the energy spectra at different tube voltages and energy deposition in the detector panel at different collimations were simulated to test the robustness of the MDCT model built in this study.Furthermore,the simulated signals in each detector element were compared with their recorded signals.The accuracies were evaluated by the relative root mean square error(RRMSE)and the structural similarity(SSIM)for each detector element and the whole detector panel,respectively.Results:The simulated energy spectra before and after passing through the phantom and simulated energy deposition in the detector panel were rational.In the scan range from the apex of lung to pubic symphysis,the RRMSE of the 18 axial projections ranged from 0.02 to 0.17,with an average of 0.08.And the SSIMs were calculated to be 0.979 and 0.976 for projections with the largest peak signal and the smallest peak signal,respectively.Conclusions:The computational model of the MDCT developed in this study is accurate and successful,it is helpful for further accurate simulations of the radiation dose and image quality of the MDCT. | Chuyan Wang Xin Lin Hongming Liu Jianwei Fu Weihai Zhuo Haikuan Liu | 2023 | Radiation Medicine and Protection2023，4，1： | 0 |
| 18 | An overview of the geology and production of the Fuling shale gas field,Sichuan Basin,China显示文摘The Fuling shale gas field in China is the largest shale gas field as well as the largest of its type discovered in any Lower Paleozoic formation.In this study,the geology and production of the upper and lower gas layers in the Fuling shale gas field are evaluated in terms of structure,shale quality,fault,initial production,and estimated ultimate recovery(EUR).The shale in the lower gas layer of the Jiaoshiba anticline is a high-quality reservoir,where the space is dominated by organic pores in kerogen,and the gas content is high.The shale gas wells reveal relatively high initial production and EUR.However,the shale in the upper gas layer of the Jiaoshiba anticline has reservoir space mainly composed of clay mineral pores and organic pores within bitumen,and the gas content is low.In terms of structure,primary gas migration may occur in the upper gas layer,resulting in free gas accumulation in the structural high,where the development effects are generally better than those in the structural low.The lower gas layer in the Pingqiao anticline,is the main interval for shale gas accumulation and development due to the high-quality shale.Under the influence of faults,the efficiency of exploration wells emplaced on top of the anticline is much lower a compared with those in the flanks.The residual synclines close to the Sichuan Basin,including the Baima and Baitao anticlines,are characterized by more recent uplifts,larger area,greater distance from the deep and large faults,and early fracture closure.Therefore,we recommend that the shale gas exploration and development should be carried out preferentially in areas close to the center of the residual synclines,featuring relatively high-pressure coefficient and moderate burial depth. | Haikuan Nie Donghui Li Guangxiang Liu Zhiyuan Lu Hu Wang Ruyue Wang Guangrong Zhang | 2020 | Energy Geoscience2020，1，3： | 0 |
| 19 | Carbon isotope evidence for shale gas preservation conditions and large methane release over million years:A case study of shale gas reservoirs of Wufeng and Longmaxi Formations in the Sichuan Basin显示文摘Although carbon isotope reversal and its reasons in shale gas reservoirs have been widely recognized,the application of the reversal is yet to be investigated.A study on high-maturity shale from Wufeng and Longmaxi Formations in the Sichuan Basin not only reveals the relationship between the degree of isotopes inversion and the production capacity(e.g.,estimated ultimate recovery(EUR))of the gas well but also indicates the preservation conditions of shale gas reservoirs.(1)Although there are differences in gas isotopes in different shale gas reservoirs,the isotope fractionation of shale gas is small during the production stage of gas wells,even when the wellbore pressure drops to zero.The main cause of the difference in carbon isotopes and their inversion degree can be the uplift time during the Yanshan period and the formation pressure relief degree of shale gas reservoirs in distinct structural positions.Thus,carbon isotope inversion is a good indicator of shale gas preservation condition and EUR of shale gas wells.(2)The degree of carbon isotope inversion correlates strongly with shale gas content and EUR.The calculation formula of shale-gas recoverable reserves was established using△δ^(13)C(δC_(1)-δC_(2))and EUR.(3)The gas loss rate and total loss amount can be estimated using the dynamic reserves and isotopic difference values of gas wells in various shale gas fields,which also reflects the current methane loss,thereby demonstrating great potential for evaluating global methane loss in shales. | Haikuan Nie Chuanxiang Sun Pei Li Zhijun Jin Quanyou Liu Hanyong Bao Baojian Shen Wei Dang | 2023 | Geoscience Frontiers2023，14，6： | 0 |
| 20 | Wall slip behavior of cemented paste backfill slurry during pipeline based on noncontact experimental detection显示文摘Wall slip is a microscopic phenomenon of cemented paste backfill(CPB)slurry near the pipe wall,which has an important influence on the form of slurry pipe transport flow and velocity distribution.Directly probing the wall slip characteristics using conventional experimental methods is difficult.Therefore,this paper established a noncontact experimental platform for monitoring the microscopic slip layer of CPB pipeline transport independently based on particle image velocimetry(PIV)and analyzed the effects of slurry temperature,pipe diameter,solid concentration,and slurry flow on the wall slip velocity of the CPB slurry,which refined the theory of the effect of wall slip characteristics on pipeline transport.The results showed that the CPB slurry had an extensive slip layer at the pipe wall with significant wall slip.High slurry temperature improved the degree of particle Brownian motion within the slurry and enhanced the wall slip effect.Increasing the pipe diameter was not conducive to the formation of the slurry slip layer and led to a transition in the CPB slurry flow pattern.The increase in the solid concentration raised the interlayer shear effect of CPB slurry flow and the slip velocity.The slip velocity value increased from 0.025 to 0.056 m·s^(-1)when the solid content improved from 55wt%to 65wt%.When slurry flow increased,the CPB slurry flocculation structure changed,which affected the slip velocity,and the best effect of slip layer resistance reduction was achieved when the transported flow rate was 1.01 m^(3)·h^(-1).The results had important theoretical significance for improving the stability and economy of the CPB slurry in the pipeline. | Zhenlin Xue Haikuan Sun Deqing Gan Zepeng Yan Zhiyi Liu | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，8： | 0 |
