1The subducted slab of Yangtze Continental block beneath the Tethyan orogen in western Yunnan显示文摘The western Yunnan area is a natural laboratory with fully developed and best preserved Tethyan orogen in the world. Seismic tomography reveals a slab-like high velocity anomaly down to 250 km beneath the western Yunnan Tethyan orogen, to its west there is a low-velocity column about 300 km wide. in the region from Lancangjiang to Mojiang an obvious low velocity in the lower crust and uppermost mantle overlies on the slab. Synthesizing the available geological and geochemical results, the present paper demonstrates that this slab-like high velocity anomaly is a part of the subducted plate of Yangtze Continental segment after the closure of Paleotethys. The collision of India and Eurasia continent starting from 50-60 MaBP might trigger thermal disturbance in the upper mantle and cause the uprising of asthenosphere, in that case the subducted Yangtze plate could be broken off, causing Cenozoic magmatic activities and underplating in the Lancangjiang-Mojiang region.Futian Liu Jianhua Liu Dalai Zhong Jiankun He Qingyu You 2000Chinese Science Bulletin2000,45,5:28
2Crust and upper mantle structure of the Ailao Shan-Red River fault zone and adjacent regions显示文摘Using arrival data of the body waves recorded by seismic stations, we reconstructed the velocity structure of the crust and upper mantle beneath the southeastern edge of the Tibetan Plateau and the northwestern continental margin of the South China Sea through a travel time tomography technique. The result revealed the apparent tectonic variation along the Ailao Shan-Red River fault zone and its adjacent regions. High velocities are observed in the upper and middle crust beneath the Ailao Shan-Red River fault zone and they reflect the character of the fast uplifting and cooling of the metamorphic belt after the ductile shearing of the fault zone, while low velocities in the lower crust and near the Moho imply a relatively active crust-mantle boundary beneath the fault zone. On the west of the fault zone, the large-scale low velocities in the uppermost mantle beneath western Yunnan prove the influence of the mantle heat flow on volcano, hot spring and magma activities, however, the upper mantle on the east of the fault zone shows a relatively stable structure similar to the Yangtze block. The low velocities of the deep mantle beneath the southeastern extending segment of the fault zone are probably related to the mantle convection produced by the pull-apart of the South China Sea.XU Yi LIU Jianhua LIU Futian SONG Haibin HAO Tianyao JIANG Weiwei 2005Science China Earth Sciences2005,48,2:18
3Relationship between Mesozoic Magmatism and Subduction in the Da Hinggan-Yanshan Area显示文摘High-resolution tomographic images of the belt crossing the Japan Trench-Changbai Mountains-Dong Ujimqin Qi are represented in this paper, revealing the shape of a subducted slab in the western Pacific region and characteristics of the lithospheric structures under the Changbai Mountains and the Da Hinggan Mountains. Studies of the spatial distribution, subduction time and the time-lag between the subduction and magmatism, combined with petrology and isotope geochemistry of the Late Mesozoic volcano-plutonic rocks from the Da Hinggan Mountains-Yanshan Mountains have further proved the independence of magmatic activities from the subduction of the Pacific plate. The Mesozoic tectono-thermal evolutionary history and structural characteristics of the lithosphere in the Da Hinggan Mountains and North China suggest that the formation and evolution of magma have probably a close relationship with the delamination and thinning of the continental lithosphere and the underplating resulting from the consequent upwelling of the asthenosphere. On the other hand, the large-scale strike-slip fault system, resulting from sinistral shearing of the Pacific plate relative to the Asian continent in the Mesozoic, is responsible for the formation and emplacement of magma on the continental margin. It was the intense crust-mantle interaction, together with structural deformation at the shallower levels that led to the large tectono-magmatic belt in the East Asian continental margin.SHAO Ji'an LIU Futian CHEN Hui HAN Qingjun 2001Acta Geologica Sinica(English Edition)2001,75,1:9
4Seismic tomography showing subduction and slab breakoff of the Yangtze block beneath the Dabie-Sulu orogenic belt显示文摘Seismic tomography reveals that a subducted ancient block has been preserved beneath the Moho of the Dabie-Sulu orogenic belt. Taking into account of geological and geochronological data, we inferred from the tomographic images that the Yangtze block was subducted northward beneath the Sino-Korean block and broken off at the depth <200 km during 200-190 Ma. The slab breakoff of the Yangtze block is the most important dynamic mechanism to control the exhumation of UHP rocks.Peifen Xu Ruomei Sun Futian Liu Qingchen Wang Bolin Cong 2000Chinese Science Bulletin2000,45,1:7
5Study on oil–source correlation by analyzing organic geochemistry characteristics: a case study of the Upper Triassic Yanchang Formation in the south of Ordos Basin, China显示文摘In the south of the Ordos Basin, the oil source of the Upper Triassic Yanchang Formation is confused all the time, which affects further exploration. In this study, oil sources from the oil layers of Ch6, Ch8 and Ch9 are all analyzed and confirmed. Through their carbon isotope value and biomarkers, characteristics of crude oils from the Yanchang Formation are analyzed. Then, the oil–source relation is discussed, with the source rocks' features.Finally, the oil–source relation is calculated through cluster analysis. It is believed that the oils from the Yanchang Formation deposit in a similar redox environment, with weak oxidation–weak reduction, and have all entered maturity stage. Ch9 crude oil is more mature than crude oils from Ch6 and Ch8, and has more advanced plants and fewer algae. Gas chromatography(GC) and gas chromatography–mass spectrometry(GC–MS) analysis show that crude oils from Ch6 and Ch8 may come from Ch7, and Ch9 crude oil may not. Cluster analysis displays that crude oils from Ch6 and Ch8 have closer squared Euclidean distance with Ch7 source rocks than Ch9 crude oil does,indicating crude oils from Ch6 and Ch8 stem from Ch7 source rocks. And Ch9 crude oil has rather close squared Euclidean distance with Ch9 source rocks, illustrating Ch9 crude oil may be from Ch9 source rocks. This research may provide the theoretical basis for the next exploration deploy in the south of Ordos Basin.Delu Li Rongxi Li Baoping Wang Zhi Liu Xiaoli Wu Futian Liu Bangsheng Zhao Jinghua Cheng Wenbin Kang 2016Acta Geochimica2016,35,4:5
6Study of ciprofloxacin removal by biochar obtained from used tea leaves显示文摘In this study,used tea leaves(UTLs) were pyrolyzed to obtain used tea-leaf biochar(UTC),and then the UTC was used as an adsorbent to remove ciprofloxacin(CIP) from aqueous solutions.Batch experiments were conducted to investigate the CIP adsorption performance and mechanism.The results showed that the CIP-adsorbing ability first increased and then declined as the UTC pyrolysis temperature increased.The UTC obtained at 450°C presented excellent CIP-absorbing ability at p H 6 and 40°C.The maximum monolayer adsorption capacity was 238.10 mg/g based on the Langmuir isotherm model.The pseudo-second-order kinetic equation agreed well with the CIP adsorption process,which was controlled by both external boundary layer diffusion and intra-particle diffusion.The characterization analysis revealed that the \OH groups,C_C bonds of aromatic rings,C\H groups in aromatic rings and phenolic C\O bonds play vital roles in the CIP adsorption process,and that the N\C,N\O,O\C_O and C\OH groups of UTC were consumed in large quantities.π–π interactions,hydrogen bonding and electrostatic attraction are inferred as the main adsorption mechanisms.The present work provides not only a feasible and promising approach for UTLs utilization but also a potential adsorbent material for removing high concentrations of CIP from aqueous solutions.Jie Li Guangwei Yu Lanjia Pan Chunxing Li Futian You Shengyu Xie Yin Wang Jianli Ma Xiaofu Shang 2018Journal of Environmental Sciences2018,30,11:5
7Structure of the crust and uppermost mantle from broadband seismic array in the western Dabie Mountains,east central China显示文摘A broadband seismic array of 7 stations was set up in the western Dabie Mountains (31°20′-31°50′N, 114°30′-115°E). Teleseismic events from May 2001 to November 2001 were collected and analyzed by radial receiver function to determine the S-wave velocity structure of the crust and uppermost mantle. The crustal thickness is 32-38 km beneath the array. The crust-mantle boundary appears as a gently north-dipping velocity discontinuity, but turns to be a velocity gradient beneath a station near the Qiliping shear zone in the south of the array. In the north of the array, a large offset of 4-6 km exists in the Moho along the Tongbai-Tongcheng shear zone, suggesting a suture zone formed by the northward subduction of the Yangtze plate beneath the North China plate. Along the Tongbai-Tongcheng shear zone, a north-dipping, EW-striking low-velocity zone was observed in the upper mantle, which may be related to the collision boundary between the Yangtze and the North China plates in the Triassic. Therefore the Tongbai-Tongcheng shear zone is the southern boundary of suture zone between the Yangtze and the North China plates. In the south of the array, a high-velocity body in the lower crust near the Qiliping shear zone probably results from the underplate of mafic magma into the lower crust, which is generally associated with large-scale extension triggered by delamination of the thickened crust.LI Hua WANG LiangShu LI Cheng LIU FuTian HU DeZhao YU DaYong 2009Science China Earth Sciences2009,52,2:4
8Exploration of Multifocal Rod Electroretinograms Recording in Human显示文摘Purpose:To test the feasibility of recording rod multifocal electroretinograms (ERG) in humans and observe appropriate recording conditions.Methods: Multifocal rod ERG were recorded using a stimulus array of 61 equalsized hexagons in two normal subjects after the dark adaptation. Flashes were blue (W47B). Blank frames between two successive flashes of hexagons varied from 0 to 14. Length of the m-sequence, bandwidth, flash frequency, flash intensities and background intensities were changed to obtain appropriate recording conditions for the clinical use.Results:Multifocal rod ERG were clearly recordable and well formed. They had an early implicit time, very small negative wave and a late implicit time, large positive wave. The positive wave was bimodal, whose timing and waveform were similar to the full-field rod ERG. The local response amplitudes can be suppressed with increase in flash frequency or background intensity, decrease in flash intensity or the size of stimulus elements.Conclusions: Multifocal rod ERG can be recorded in human and can provide topographical maps of retinal function that have clinical usage. 212-1 m-sequence length, 3F blank frames and 3~ 300 Hz bandwidth were suggested to appropriate recording conditions.Changzheng Chen, Lezheng Wu, De-Zheng Wu, Shixian Long Jiongji Liang, Futian Jiang, Libing JiangZhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China 2002眼科学报2002,18,3:3
9Necessary and sufficient checkpoint selection for temporal verification of high-confidence cloud workflow systems显示文摘On-time completion is an important temporal Qo S(Quality of Service) dimension and one of the fundamental requirements for high-confidence workflow systems. In recent years, a workflow temporal verification framework, which generally consists of temporal constraint setting, temporal checkpoint selection, temporal verification, and temporal violation handling, has been the major approach for the high temporal Qo S assurance of workflow systems. Among them, effective temporal checkpoint selection, which aims to timely detect intermediate temporal violations along workflow execution plays a critical role. Therefore, temporal checkpoint selection has been a major topic and has attracted significant efforts. In this paper, we will present an overview of workflow temporal checkpoint selection for temporal verification. Specifically, we will first introduce the throughput based and response-time based temporal consistency models for business and scientific cloud workflow systems,respectively. Then the corresponding benchmarking checkpoint selection strategies that satisfy the property of'necessity and sufficiency' are presented. We also provide experimental results to demonstrate the effectiveness of our checkpoint selection strategies, and finally points out some possible future issues in this research area.WANG FuTian LIU Xiao YANG Yun 2015Science China(Information Sciences)2015,58,5:3

15Influence on lacustrine source rock by hydrothermal fluid: a case study of the Chang 7 oil shale, southern Ordos Basin显示文摘Hydrothermal fluid activity during sedimentation of the Triassic Yanchang Formation in the Ordos Basin and the impact of said activity on formation and preservation conditions of source rocks have received little attention. Oil yield, major element, trace element, rare earth element, and total sulfur(TS) data from the oil shale within the Yanchang are here presented and discussed in the context of hydrothermal influence. Oil shale samples returned relatively high total organic carbon(TOC), in the range of 4.69%–25.48%. A high correlation between TS and TOC suggests TS in the oil shale is dominated by organic sulfur and affected by organic matter. The low Al/Si ratio of oil shale samples implies quartz is a major mineralogical component. Si/(Si + Al + Fe) values suggest close proximity of the oil shale to a terrigenous source.d Eu; Fe versus Mn versus(Cu + Co + Ni) 9 10; and Si O2/(K2 O + Na2 O) versus Mn O/Ti O2, Fe/Ti, and(Fe + Mn)/Ti are evidence of hydrothermal fluid activity during oil shale sedimentation, and d U and U/Th of the oil shale indicate reducing conditions. The Sr/Ba of oil shale samples suggests fresh-water deposition. The high correlations of Fe/Ti and(Fe + Mn)/Ti with d U, U/Th, and TS demonstrate that hydrothermal fluid activity promotes reducing conditions. Sr/Ba ratios had low correlation with Fe/Ti and(Fe + Mn)/Ti, implying that hydrothermal fluid activity had little impact on paleosalinity. Fe/Ti,(Fe + Mn)/Ti, d U, U/Th, and Cu + Pb + Zn all exhibitedhigh positive correlation coefficients with TOC in oil shale samples, suggesting that more intense hydrothermal fluid activity improves conditions in favor of formation and preservation of organic matter.Delu Li Rongxi Li Zengwu Zhu Xiaoli Wu Futian Liu Bangsheng Zhao Baoping Wang 2018Acta Geochimica2018,37,2:1

19Resource and Environmental Issues in Transitional China:A Perspective from the Interaction Among Market,Government and Society显示文摘Along with the rapid growth of economy in the postreform period after 1979,China has faced severe problems of resource overusing and environmental degradation which would threaten the sustainable development of economy and society.This article explores an effective mechanism of managing resource and environment in China.It examines some major resource and environmental issues,and constructs a framework of institution innovation to cover three sectors(government,market and society) . In addition,the article analyzes their experience and evaluation in resource management and environmental conservation during the transitional period.We argue that the combination of market regulation,government intervention and public participation is an effective way of allocating resource and protecting environment. Some suggestions are put forward to balance the relationship between them,including coordinating role of government and market,building platform for market operation and creating an atmosphere of public participation.Zhao Haixia Qu Futian Zhu Peixin Shi Xiaoping 2010Chinese Journal of Population,Resources and Environment2010,8,2:1
