2The influence of the metal net charge of non-metallocene early transition metal catalyst on the ethylene polymerization activity显示文摘The net charges on central metals of a serial non-metallocene early transition metal catalysts (FI catalyst) with similar steric hindrance were caculated with MM-QEq (molecular mechmism-charge equilibration) method and associated with ethylene polymerization activities of these FI catalyts. It was found that the activity increased with the net charge on metal if ignoring the influence of the steric hindrance. In other words, introduction of strong and/or more electron-withdrawing groups onto the ligand of FI catalyst would enhance the activity of the catalyst. This conculsion gave a direction to designing new FI catalyst with higher activity.WU ChunHong LI HuaYi FENG YuQi HU YouLiang 2008Chinese Science Bulletin2008,53,20:1
3Blockchain Data Privacy Access Control Based on Searchable Attribute Encryption显示文摘Data privacy is important to the security of our society,and enabling authorized users to query this data efficiently is facing more challenge.Recently,blockchain has gained extensive attention with its prominent characteristics as public,distributed,decentration and chronological characteristics.However,the transaction information on the blockchain is open to all nodes,the transaction information update operation is even more transparent.And the leakage of transaction information will cause huge losses to the transaction party.In response to these problems,this paper combines hierarchical attribute encryption with linear secret sharing,and proposes a blockchain data privacy protection control scheme based on searchable attribute encryption,which solves the privacy exposure problem in traditional blockchain transactions.The user’s access control is implemented by the verification nodes,which avoids the security risks of submitting private keys and access structures to the blockchain network.Associating the private key component with the random identity of the user node in the blockchain can solve the collusion problem.In addition,authorized users can quickly search and supervise transaction information through searchable encryption.The improved algorithm ensures the security of keywords.Finally,based on the DBDH hypothesis,the security of the scheme is proved in the random prediction model.Tao Feng Hongmei Pei Rong Ma Youliang Tian Xiaoqin Feng 2021Computers, Materials & Continua2021,,1:1
4Fine-grained gravity flow sedimentation and its influence on development of shale oil sweet sections in lacustrine basins in China显示文摘The geological conditions and processes of fine-grained gravity flow sedimentation in continental lacustrine basins in China are analyzed to construct the model of fine-grained gravity flow sedimentation in lacustrine basin,reveal the development laws of fine-grained deposits and source-reservoir,and identify the sweet sections of shale oil.The results show that fine-grained gravity flow is one of the important sedimentary processes in deep lake environment,and it can transport fine-grained clasts and organic matter in shallow water to deep lake,forming sweet sections and high-quality source rocks of shale oil.Fine-grained gravity flow deposits in deep waters of lacustrine basins in China are mainly fine-grained high-density flow,fine-grained turbidity flow(including surge-like turbidity flow and fine-grained hyperpycnal flow),fine-grained viscous flow(including fine-grained debris flow and mud flow),and fine-grained transitional flow deposits.The distribution of fine-grained gravity flow deposits in the warm and humid unbalanced lacustrine basins are controlled by lake-level fluctuation,flooding events,and lakebed paleogeomorphology.During the lake-level rise,fine-grained hyperpycnal flow caused by flooding formed fine-grained channel–levee–lobe system in the flat area of the deep lake.During the lake-level fall,the sublacustrine fan system represented by unconfined channel was developed in the flexural slope breaks and sedimentary slopes of depressed lacustrine basins,and in the steep slopes of faulted lacustrine basins;the sublacustrine fan system with confined or unconfined channel was developed on the gentle slopes and in axial direction of faulted lacustrine basins,with fine-grained gravity flow deposits possibly existing in the lower fan.Within the fourth-order sequences,transgression might lead to organic-rich shale and fine-grained hyperpycnal flow deposits,while regression might cause fine-grained high-density flow,surge-like turbidity flow,fine-grained debris flow,mud flow,and fine-grained transitional flow deposits.Since the Permian,in the shale strata of lacustrine basins in China,multiple transgression-regression cycles of fourth-order sequences have formed multiple source-reservoir assemblages.Diverse fine-grained gravity flow sedimentation processes have created sweet sections of thin siltstone consisting of fine-grained high-density flow,fine-grained hyperpycnal flow and surge-like turbidity flow deposits,sweet sections with interbeds of mudstone and siltstone formed by fine-grained transitional flows,and sweet sections of shale containing silty and muddy clasts and with horizontal bedding formed by fine-grained debris flow and mud flow.The model of fine-grained gravity flow sedimentation in lacustrine basin is significant for the scientific evaluation of sweet shale oil reservoir and organic-rich source rock.ZOU Caineng FENG Youliang YANG Zhi JIANG Wenqi ZHANG Tianshu ZHANG Hong WANG Xiaoni ZHU Jichang WEI Qizhao 2023Petroleum Exploration and Development2023,50,5:1
5What are the Lacustrine Fine-Grained Gravity Flow Sedimentation Process and the Genetic Mechanism of Sweet Sections for Shale Oil?显示文摘0 INTRODUCTION Oil in continental Basins is the main contributor to petroleum reserves and production in China.The exploration targets of the oil in continental Basins have experienced a transformation from conventional oil,whose reservoirs are mainly composed of coarse-grained deposits outside the lacustrine basin,and coarse-medium-grained sediments deposited near the shoreline of the lacustrine basin.Caineng Zou Youliang Feng Zhi Yang Wenqi Jiang Songqi Pan Tianshu Zhang Xiaoni Wang Jichang Zhu Jiarui Li 2022Journal of Earth Science2022,33,5:1

7Position Sensorless Control System of Permanent Magnet Synchronous Linear Motor Based on Sliding Mode Observer with an Improved Phase-Locked Loop显示文摘In this paper,position sensorless control system of permanent magnet synchronous linear motor(PMSLM)based on sliding mode observer(SMO)with an improved phase-locked loop(PLL)is studied.Firstly,according to the mathematical model,a SMO is designed for sensorless control PMSLM drive.Thereafter,an improved PLL is proposed to tackle the imperfection of data overflow existed in the traditional PLL.The designed SMO incorporating with the improved PLL can be effectively suppress the pulsation of the estimated position and hence the chattering of the derived electrical angular velocity.At last,simulated and experimental results are presented to verify the effectiveness and feasibility of the position sensorless control system.Jin Zhang Youliang Tang Feng Yu 2021Energy Engineering2021,118,4:0
8Late Mesozoic tectonostratigraphic division and correlation of the Bohai Bay basin: Implications for the Yanshanian Orogeny显示文摘We present the results of Mesozoic sequences of the Bohai Bay basin in North China, based mainly on geochronology and interpretations of seismic profiles and logging data. Five tectono-stratigraphic sequences are defined: Lower-Middle Triassic, Lower-Middle Jurassic, Upper Jurassic, Lower Cretaceous and Upper Cretaceous. Based on an analysis of detrital zircons, the clastic rocks recorded two intervals of Jurassic magmatic activity, during 180–175 and 160–152 Ma, which can be correlated to the Nandaling and Tiaojishan Formations in the Yanshan area, respectively. However, since Jurassic volcanic rocks have not yet been found in the Bohai Bay basin, we speculate that these two stages of activity were mainly concentrated around the periphery of the North China Craton(NCC) rather than within. Based on an analysis of zircons from volcanic rocks and pyroclastics, the early Cretaceous magmatism in the Bohai Bay basin can be divided into two stages, 125–120 and 110–100 Ma,which can be correlated to magmatism in the eastern part of the NCC. The zircon ages indicate an absence of volcanic activity during the late Tuchengzi and Zhangjiakou periods which may correlate to the uplift of the Bohai Bay basin in the late Late Jurassic. Comparison of the development of Mesozoic basins and sedimentary strata in the central-eastern part of Yanshan tectonic belt and the the Bohai Bay basin indicates that the two areas are generally comparable, but with substantial differences.The central-eastern part of the Yanshan structural belt lacks Early-Middle Triassic strata, and the Bohai Bay basin lacks late Jurassic-early Cretaceous strata. Based on research results from late Mesozoic sedimentary structures in the central and eastern parts of the Yanshan tectonic belt, we infer that episode A of the Yanshanian Orogeny was weak in the Bohai Bay basin and its periphery, while episode B of the Yanshanian Orogeny had a strong influence on the Bohai Bay basin and its periphery. The available data reveal differences in the expression of these episodes: the Bohai Bay basin is characterized by vertical uplift, and the northern margin of NCC is characterized by horizontal compression uplift.Jichang ZHU Youliang FENG Qing-Ren MENG Fengcheng WU Hao LI Haitao LIU Feipeng ZHANG Tianyu WANG Guoli WU Caineng ZOU Rixiang ZHU 2019Science China Earth Sciences2019,62,11:0
9Prospective study on observations of γ-ray sources in the Galaxy using the HADAR experiment显示文摘The High Altitude Detection of Astronomical Radiation(HADAR)experiment is a refracting terrestrial telescope array based on the atmospheric Cherenkov imaging technique.It focuses the Cherenkov light emitted by extensive air showers through a large aperture water-lens system for observing very-high-energyγ-rays and cosmic rays.With the advantages of a large field-of-view(FOV)and low energy threshold,the HADAR experiment operates in a large-scale sky scanning mode to observe galactic sources.This study presents the prospects of using the HADAR experiment for the sky survey of TeVγ-ray sources from TeVCat and provids a one-year survey of statistical significance.Results from the simulation show that a total of 23 galactic point sources,including five supernova remnant sources and superbubbles,four pulsar wind nebula sources,and 14 unidentified sources,were detected in the HADAR FOV with a significance greater than 5 standard deviations(σ).The statistical significance for the Crab Nebula during one year of operation reached 346.0σand the one-year integral sensitivity of HADAR above 1 TeV was~1.3%–2.4%of the flux from the Crab Nebula.Xiangli Qian Huiying Sun Tianlu Chen Danzengluobu Youliang Feng Qi Gao Quanbu Gou Yiqing Guo Hongbo Hu Mingming Kang Haijin Li Cheng Liu Maoyuan Liu Wei Liu Bingqiang Qiao Xu Wang Zhen Wang Guangguang Xin Yuhua Yao Qiang Yuan Yi Zhang 2022Frontiers of physics2022,17,6:0
10Study on the efficiency of the underground muon detectors in YangBaJing Hybrid Array显示文摘Purpose Theγ-ray astronomy at 100 TeV is important to unravel the puzzles related to the origin and acceleration of the Galactic cosmic rays up to PeV energy.The YangBaJing Hybrid Array(YBJ-HA),about 2%the scale of LHAASO-KM2A,is such a kind of detection instrument capable of detecting 100 TeVγ-rays.And the muon detection efficiency stability of the MD array in YBJ-HA is crucial for high qualityγ-ray observation.To measure and monitor the muon detection efficiency,we develop a method in this work.Methods We develop a muon bundle method to measure and monitor the efficiency of each muon detector.In this method,muon detection efficiency of the target MD unit is calculated based on the surrounding MD units and the MC simulation.Results The average actual muon detection efficiency of the 16 MD units is up to 83.4%during 4 years’observation.Conclusions The muon detection efficiency of each MD unit is found to be stable during 4 years’operation.In the future,a similar method may be applicable to the muon detection efficiency study for LHAASO.Zhen Wang Youliang Feng Cheng Liu Yiqing Guo Hongbo Hu Tianlu Chen Danzeng Luobu Jiancheng He Yuhua Yao Yi Zhang 2019Radiation Detection Technology and Methods2019,3,3:0
