| 1 | Late stage thermal history of the Songliao Basin and its tectonic implications: Evidence from apatite fission track (AFT) analyses显示文摘Apatite Fission Track (AFT) data from the Songliao Basin indicates that the late stage tectonic movements in the Songliao Basin have zoning in space and episodes in time. The late stage tectonic movements started from the east part of the basin and migrated westward. AFT ages in the east part of the basin are older than those in the west part of the basin, suggesting that the uplift occurred earlier in the east than in the west. The denudation thickness in the east part of the basin is significantly greater than that in the centre and west. The thermal history evolved two episodes of rapid cooling and subsequent slow cooling processes. Age-depth relationship derived from the AFT data indicates a four-episode denudation history. Further Monte Carlo random simulation of the AFT data reveals the four changing points of the thermal evolution at 65 Ma, 43.5 Ma, 28 Ma and 15 Ma, respectively. The uplifting and denudation rates from different episodes of evolution are proportional to the plate convergence rate. Based on the above analyses and the regional geologic background, it is concluded that the late stage thermal events in the Songliao Basin are the far field response to the subduction of the Pacific Plate under the Eurasian Plate. The first episode of the rapid cooling probably started at the end of the Nenjiang Formation, climaxed at the end of the Cretaceous and ceased at the Late Eocene. The subsequent slow cooling lasts another 15 Ma. The first episode of the evolution is the far field response to the major episode of the Yanshan Movement and subsequent series of the tectonic reorganization, especially the directional change of the Pacific Movement and also the subduction of the Indian Plate underneath the Eurasian Plate. While the second episode of the evolution is the far field response to the extension and closure of the Sea of Japan. Extension led to the migration and converging of the mantle heat flow to the Sea of Japan and resulted in the rapid cooling of the Songliao Basin. | XIANG CaiFu1,2?, FENG ZhiQiang3, PANG XiongQi1,2, WU HeYong3 & LI JunHong1,2 1 Basin and Reservoir Research Center, China University of Petroleum, Beijing 102249, China 2 Key Laboratory for Hydrocarbon Accumulation in China University of Petroleum, Ministry of Education, Beijing 102249, China 3 Prospecting and Exploration Institute of Daqing Oil Field, Daqing 163458, China | 2007 | Science China Earth Sciences2007，50，10： | 6 |
| 2 | Present geotemperature and its suggestion to natural gas generation in Xujiaweizi fault-depression of the northern Songliao Basin显示文摘According to stastistic of present geotemperatures at the depths of 1000,2000,3000 and 4000 m,respectively in the Xujiaweizi fault-depression of the north Songliao Basin,the result indicates that Xujiaweizi fault-depression falls in the high geotemperature area,with the higher geothermal gradient in the depression layer than that in the fault-depression layer.The geothermal gradient decreases with the increasing of the depth.The thermal conductivity of rock greatly controls the geothermal gradient.The main factors constraining the current geotemperature include thermal configuration of the earth's crust, deep faults,distribution and abundance of radioelements.The high geotemperature is in favour of generation of deep gas. | ZHOU QingHua 1,2 ,FENG ZiHui 3 &MEN GuangTian 3 1 Research Institute of Petroleum Exploration and Development,PetroChina,Beijing 100083,China 2 Geological Logging Subcompany of Daqing Oil Field Company Ltd.,Daqing 163411,China 3 Research Institute of Petroleum Exploration and Development of Daqing Oil field Company Ltd.,Daqing 163732,China | 2008 | Science China Earth Sciences2008，51，S1： | 3 |
| 3 | Characteristics of remaining oil viscosity in water-and polymer-flooding reservoirs in Daqing Oilfield显示文摘The experimental analysis of 21 crude oil samples shows a good correlation between high molecular-weight hydrocarbon components (C 40+) and viscosity.Forty-four remaining oil samples extracted from oil sands of oilfield development coring wells were analyzed by high-temperature gas chromatography (HTGC),for the relative abundance of C 21-,C 21-C 40 and C 40+ hydrocarbons.The relationship between viscosity of crude oil and C 40+ (%) hydrocarbons abundance is used to expect the viscosity of remaining oil.The mobility characteristics of remaining oil,the properties of remaining oil,and the next displacement methods in reservoirs either water-flooded or polymer-flooded are studied with rock permeability,oil saturation of coring wells,etc.The experimental results show that the hydrocarbons composition,viscosity,and mobility of remaining oil from both polymer-flooding and water-flooding reservoirs are heterogeneous,especially the former.Relative abundance of C 21- and C 21-C 40 hydrocarbons in polymer-flooding reservoirs is lower than that of water-flooding,but with more abundance of C 40+ hydrocarbons.It is then suggested that polymer flooding must have driven more C 40- hydrocarbons out of reservoir,which resulted in relatively enriched C 40+,more viscous oils,and poorer mobility.Remaining oil in water-flooding reservoirs is dominated by moderate viscosity oil with some low viscosity oil,while polymer-flooding mainly contained moderate viscosity oil with some high viscosity oil.In each oilfield and reservoir,displacement methods of remaining oil,viscosity,and concentration by polymer-solution can be adjusted by current viscosity of remaining oil and mobility ratio in a favorable range.A new basis and methods are suggested for the further development and enhanced oil recovery of remaining oil. | XU ZhengShun,ZHANG JuHe,FENG ZiHui,FANG Wei & WANG FengLan Exploration and Development Research Institute,Daqing Oilfield Company Ltd.,Daqing 163712,China | 2010 | Science China Earth Sciences2010，53，1： | 3 |
| 4 | Effect of Different Sowing Dates in South Henan 's Rice-growing Areas on the Growth and Yield of Ratoon Rice显示文摘In order to determine the optimal sowing date of ratoon rice in South Henan's rice-growing areas,this paper performs a comparative analysis of rice growth process,seedling quality and yield of first season rice and ratoon rice under different sowing date treatments. The results show that under climatic conditions( 2014),by using dry seedling cultivation in a small plastic shed,the growth of seedling sown on February21 was affected,while the sowing treatments from March 1 to April 11 can breed normal seedlings,and in this period,the maturity period of first season rice was delayed with prolonged sowing date,and ratoon rice yield declined with prolonged sowing date( total production of rice sown on 11 March reaching a peak). Thus,it is considered that the optimal sowing date of ratoon rice in South Henan's rice-growing areas is mid-March. | Xiangchen LIU Daqing FENG Guilong YU Haiying ZHAO Li QIAO Yanting LI Xuejun FAN Mingcheng LIU Qiuju ZHANG | 2016 | Asian Agricultural Research2016，8，2： | 3 |

| 6 | Toxicity mechanisms and bioavailability of copper to fish based on an adverse outcome pathway analysis显示文摘Copper(Cu)exists in a variety of forms in different aquatic environments,and affects their bioavailability.In this study we provide a systematic review on toxicity of Cu which focuses on identifying evidence in the mechanisms of Cu toxicity,and apply an adverse outcome pathway(AOP)analysis to identify multiple potential mechanisms and their interactions of Cu toxicity to fish.This analysis process included the mechanisms of behavior toxicant,oxidative toxicant,ion regulation disruption toxicity,as well as endocrine disruption toxicity.It was found that at low levels of Cu exposure,swimming,avoid predators,locating prey and other sensory functions will be impaired,and the organism will suffer from metabolic alkalosis and respiratory acidosis following the inhibition of the carbonic anhydrase active.The main pathway of acute toxicity of Cu to fish is the inhibition of the Na^(+)/K^(+)-ATPase enzyme,and lead to reduced intracellular sodium absorption,as well as Cu-induced increased cell permeability,in turn resulting in increased sodium ion loss,leading to cardiovascular collapse and respiratory insufficiency.The endocrine disruption toxicity of Cu to fish caused growth inhibition and reproductive reduction.In addition,there are several key pathways of Cu toxicity that are affected by hardness(e.g.,Ca^(2+))and intracellular DOC concentrations,including inhibiting Cu-induction,improving branchial gas exchange,altering membrane transport functions,decreasing Na+loss,and increasing Na+uptake.The results of the AOP analysis will provide a robust framework for future directed research on the mechanisms of Cu toxicity. | Wei Liao Ziwei Zhu Chenglian Feng Zhenfei Yan Yajun Hong Daqing Liu Xiaowei Jin | 2023 | Journal of Environmental Sciences2023，，5： | 1 |

| 12 | Simulation research on cable-laying scheme of HIAF dipole power supply显示文摘Background A strong electromagnetic force is the major cause of vibration in dipole power supply cables.Moreover,the long-term operation of cables under vibration conditions leads to structural fatigue failure.Purpose and methods To investigate the cable-laying scheme of a dipole power supply,a finite element model for the electromagnetic–structural coupling between cables and cleats was established.The electrodynamic forces were simulated for fixed-length cables in the horizontal,vertical,and bent models under pulse-current excitation.Subsequently,based on the optimized arrangement mode,the deformation of the cables and the stresses of the cleats were obtained.Results A small cable electrodynamic force was observed in the positive–negative interlace arrangement,and the cable deformation was caused by electrodynamic forces.The maximum cleat deformation occurred at the position with the largest electrodynamic force,where the cleats were reinforced.Moreover,the mechanical characteristics of the cables and cleats under pulse-current excitation are described intuitively and quantitatively,providing theoretical support for the cable-laying scheme of the dipole power supply. | Runzu Zhang Anhui Feng Ye Liu Zhongzu Zhou Yongbo Zhang Pengfei Liu Jiancheng Yang Daqing Gao Shuang Ruan Guodong Shen Hengmin Liu | 2023 | Radiation Detection Technology and Methods2023，7，1： | 0 |
