| 1 | Ms8.0汶川地震产生的应力变化空间分布及其对地震活动性的影响显示文摘采用已公布的5个震源破裂模型,计算了Ms8.0汶川地震产生的库仑破裂应力变化,分析了应力变化与后续地震活动空间分布的相关性.以震源模型引起的不确定性分析为基础,研究了汶川地震在周边断裂上引起的库仑应力变化,并重点探讨了应力变化引起的地震活动性随时间的相对变化趋势.结果表明,以Ji模型和王卫民模型计算出的应力变化空间分布较好地与后续地震活动的空间分布相对应.最大的应力减小区主要分布于震源断层的东西两侧,最大的应力增加区分布于震源断层面以及断层面南北两个端部的邻近区域,此外还有一个北西-南东向的显著增加区位于主震断层面南段附近的汶川-映秀一带,该区域已发生了较多的余震活动,且地震活动呈现继续扩散的趋势,是未来地震危险性较高的地区.汶川地震引起了周边多数断裂不同程度的地震活动性增强,活动性增强最显著的是彭县-灌县断裂和青川断裂,未来100年内都维持在震前的2倍以上,地震活动恢复至背景水平所需的时间基本都达到800~900年;西秦岭南缘断裂、龙泉山断裂、鲜水河断裂、玉龙希断裂、安宁河断裂、岷江断裂和阿坝断裂的地震活动性受汶川地震的影响较小,震后地震活动率与震前相比不足2倍,并且扰动恢复时间较短.因抚边河断裂和虎牙断裂处于应力减小区域,未来地震活动性可能会减弱.受到汶川地震产生的应力变化影响,青川断裂和彭县-灌县断裂的未来发震危险性较高. | 解朝娣 朱元清 Xinglin LEI 于海英 虎雄林 | 2010 | 中国科学:地球科学2010，40，6： | 48 |
| 2 | Directional hydraulic fracturing to control hard-roof rockburst in coal mines显示文摘Hard roof is the main factor that induces rock-burst.In view of the present obvious weakness of control measures for hard roof rockburst in domestic collieries,the mechanism and field application of directional hydraulic fracturing technology for rock-burst prevention have been investigated in this paper using theoretical analysis and numerical simulation.The results show that the weighting span of the main roof and the released kinetic energy as well as the total elastic energy decreased greatly after the directional fracturing of hard roof with the mining progression,thereby reducing the rockburst hazard degree to coal body.The directional hydraulic fracturing technology was carried out in 6305 working face of Jisan Coal Mine to prevent rockburst.Field practices have proved that this technology is much simpler and safer to operate with better prevention effect compared with blasting.By optimizing the operation procedures and developing a new technology of automated high-pressure delivery pipe,the maximum fracturing radius now reaches more than 9 m and the borehole depth exceeds 20 m.Additionally,drilling cutting method was applied to monitor the stress of the coal mass before and after the fracturing,and the drill cuttings dropped significantly which indicates that the burst prevention effect of directional hydraulic fracturing technology is very remarkable.The research results of this paper have laid a theoretical and practical foundation for the widespread application of the directional hydraulic fracturing technology in China. | Fan Jun Dou Linming He Hu Du Taotao Zhang Shibin Gui Bing Sun Xinglin | 2012 | International Journal of Mining Science and Technology2012，22，2： | 28 |
| 3 | Growing seismicity in the Sichuan Basin and its association with industrial activities显示文摘In the Sichuan Basin,seismic activity has been low historically,but in the past few decades,a series of moderate to strong earthquakes have occurred.Especially since 2015,earthquake activity has seen an unprecedented continuous growth trend,and the magnitude of events is increasing.Following the M5.7 Xingwen earthquake on 18 Dec.2018,which was suggested to be induced by shale gas hydraulic fracturing,a swarm of earthquakes with a maximum magnitude up to M6.0 struck Changning and the surrounding counties.Questions arose about the possible involvement of industrial actions in these destructive events.In fact,underground fluid injection in salt mine fields has been occurring in the Sichuan Basin for more than70 years.Disposal of wastewater in natural gas fields has also continued for about 40 years.Since 2008,injection for shale gas development in the southern Sichuan Basin has increased rapidly.The possible link between the increasing seismicity and increasing injection activity is an important issue.Although surrounded by seismically active zones to the southwest and northwest,the Sichuan Basin is a rather stable region with a wide range of geological settings.First,we present a brief review of earthquakes of magnitude 5 or higher since 1600 to obtain the long-term event rate and explore the possible link between the rapidly increasing trend of seismic activity and industrial injection activities in recent decades.Second,based on a review of previous research results,combined with the latest data,we describe a comprehensive analysis of the characteristics and occurrence conditions of natural and injection-induced major seismic clusters in the Sichuan Basin since 1700.Finally,we list some conclusions and insights,which provide a better understanding of why damaging events occur so that they can either be avoided or mitigated,point out scientific questions that need urgent research,and propose a general framework based on geomechanics for assessment and management of earthquake-related risks. | Xinglin LEI Jinrong SU Zhiwei WANG | 2020 | Science China Earth Sciences2020，63，11： | 27 |
| 4 | Possible link between long-term and short-term water injections and earthquakes in salt mine and shale gas site in Changning,south Sichuan Basin, China显示文摘Late at night on 17 June 2019,a magnitude 6.0 earthquake struck Shuanghe Town and its surrounding area in Changning County,Sichuan,China,becoming the largest earthquake recorded within the southern Sichuan Basin.A series of earthquakes with magnitudes up to 5.6 occurred during a short period after the mainshock,and we thus refer to these earthquakes as the Changning M6 earthquake sequence(or swarm).The mainshock was located very close to a salt mine,into which for^3 decades fresh water had been extensively injected through several wells at a depth of 2.7–3 km.It was also near(within^15 km)the epicenter of the 18 December 2018 M5.7 Xingwen earthquake,which is thought to have been induced by shale gas hydraulic fracturing(HF),prompting questions about the possible involvement of industrial activities in the M6 sequence.Following previous studies,this paper focuses on the relationship between injection and seismicity in the Shuanghe salt field and its adjacent Shangluo shale gas block.Except for a period of serious water loss after the start of cross-well injection in 2005–2006,the frequency of earthquakes shows a slightly increasing tendency.Overall,there is a good correlation between the event rate in the Shuanghe area and the loss of injected water.More than 400 M≥3 earthquakes,including 40 M≥4 and 5 M≥5 events,had been observed by the end of August 2019.Meanwhile,in the Shangluo area,seismicity has increased during drilling and HF operations(mostly in vertical wells)since about 2009,and dramatically since the end of 2014,coincident with the start of systematic HF in the area.The event rate shows a progressively increasing background with some fluctuations,paralleling the increase in HF operations.More than 700 M≥3 earthquakes,including 10 M≥4 and 3 M≥5 in spatially and temporally clustered seismic events,are correlated closely with active fracturing platforms.Well-resolved centroid moment tensor results for M≥4 earthquakes were shown to occur at very shallow depths around shale formations with active HF,in agreement with some of the clusters,which occurred within the coverage area of temporary or new permanent monitoring stations and thus have been precisely located.After the Xingwen M5.7 earthquake,seismic activity in the salt well area increased significantly.The Xingwen earthquake may have created a unidirectional rupture to the NNW,with an end point close to the NW-trending fault of the Shuanghe earthquake.Thus,a fault in the Changning anticline might have terminated the fault rupture of the Xingwen earthquake,possibly giving the Xingwen earthquake a role in promoting the Changning M6 event. | XingLin Lei ZhiWei Wang JinRong Su | 2019 | Earth and Planetary Physics2019，3，6： | 24 |
| 5 | Response of runoff in the headwater region of the Yellow River to climate change and its sensitivity analysis显示文摘在到气候变化和它的敏感的黄河的 headwater 区域的流量的反应在时期期间在四个水文学车站和十个气象站基于测量数据被分析 19592008。结果显示在这个区域的温度的那个变化与全球温暖和在在这个区域的每个分区的温度一直在介绍的年度一般水准的变化有一种明显的相应关系过去的 50 年里的一个变动、升起的状态。因为不同地理位置和环境的影响,然而,降水的变化在总体上生产流量的区域一直在介绍的年度降水的各种各样的区域,和变化是比在这个区域的温度的变化更复杂的过去的 50 年里的一个变动、减少的状态。并且在这个区域在流量和降水和温度之间有一种显著非线性的相互关系。因为,自从 1990,在这个区域的流量连续地一直在减少降水总体上生产流量的区域显然减少,年度平均温度连续地升起。总体上,当在在 Jimai 上面的分区的流量相应地在在这个区域的其它比那对温度变化更敏感时,在黄河的 headwater 区域的每个分区的流量对降水变化相当敏感。 | LAN Yongchao ZHAO Guohui ZHANG Yaonan WEN Jun HU Xinglin LIU Jinqi GU Minglin CHANG Junjie MA Jianhua | 2010 | Journal of Geographical Sciences2010，20，6： | 20 |
| 6 | Pattern of stress change and its effect on seismicity rate caused by M_s8.0 Wenchuan earthquake显示文摘We use five published source models to calculate the Coulomb failure stress changes induced by the Ms8.0 Wenchuan earthquake, and analyze the association between stress changes and the subsequent earthquakes. Based on the analysis of uncertainties resulting from source models, we determine the stress changes on nearby faults caused by the Wenchuan earthquake. Moreover, we focus on the seismicity rate change as a function of time on every fault under the influence of stress changes. The results indicate that the spatial distributions of aftershocks correlate well with the regions where stress is calculated to increase using the related models. The largest lobes of dropped stress lie in the west and east sides of source fault. The largest lobes of increased failure stress close to southern and northern ends of the source fault extend into the whole source failure plane. In addition, another region of increased stress lies in the Wenchuan-Yingxiu zone close to the southern segment of source fault, where a large number of aftershocks have occurred. And subsequent earthquakes seem to extend to even more remote distances; therefore, this area also has a high risk of seismic hazard. We find that the positive stress changes on nearby faults imposed by the Wenchuan earthquake produce an encouraging effect on seismicity rate. The effect is most significant on the Pengxian-Guanxian fault and Qingchuan fault, the value of seismicity rate maintains two times greater than the value before the mainshock for the next hundred years on these faults, and the time needed for the aftershock rate to recover to the pre-mainshock seismicity rate can reach up to 800-900 yr. The influence is not significant on the western Qinling fault, the Longquanshan fault, the Xianshuihe fault, the Yulongxi fault, the Anninghe fault, the Minjiang fault, and the Aba fault. Compared with the seismicity rate on these faults before the mainshock, the aftershock rate is raised by less than two times, and the time of perturbation duration is not long. The stress changes on the Fubianhe fault and Huya fault are negative, which reduce the seismicity for the next thousand years. Under the influence of stress changes caused by the Wenchuan earthquake, both Pengxian-Guanxian fault and Qingchuan fault have a high risk of earthquake occurrence. | XIE ChaoDi ZHU YuanQing LEI XingLin YU HaiYing HU XiongLin | 2010 | Science China Earth Sciences2010，53，9： | 17 |
| 7 | Laboratory acoustic emission study for earthquake generation process显示文摘Since the similarity in size distribution of earthquakes and acoustic emissions(AE) was found in the1960 s, many laboratory studies have been motivated by the need to provide tools for the prediction of mining failures and natural earthquakes. This paper aims, on the one hand,to draw an outline of laboratory AE studies in the last50 years, which have addressed seismological problems.Topics include the power laws in which the similarity between AEs and earthquakes is involved and progress that has been made in AE technology and laboratory AE study.On the other hand, this study will highlight some key issues intensively discussed, especially in the last three decades,such as aspects related to the pre-failure damage evolution,fault nucleation and growth in brittle rocks and discuss factors governing these processes. | Xinglin Lei Shengli Ma | 2014 | Earthquake Science2014，27，6： | 12 |

| 9 | 鄂尔多斯块体周缘地区近期地震活动性与汶川地震应力触发作用的关系显示文摘采用β统计对汶川地震前后鄂尔多斯块体周缘地区的地震活动率进行了空间扫描分析,并采用JiChen的震源破裂模型计算了汶川地震产生的库仑破裂应力变化,以研究鄂尔多斯块体周缘地区近期地震活动性与汶川地震应力触发作用的关系。结果发现,鄂尔多斯块体西南缘弧形断裂束的南东段与南缘渭河盆地的地震活动率在汶川地震后提高显著,其他区域的地震活动率没有明显提高,库仑破裂应力计算得到两个区域的应力变化范围分别为0.005~0.02 MPa和0.001~0.01 MPa,表明汶川地震有可能触发了这两个区域的地震活动。鄂尔多斯块体东缘的山西断陷带处于库仑破裂应力计算的应力增加区,应力变化范围为0~0.012 MPa,2009年3月以来发生的4次ML4.5~5.2级强有感至微破坏地震有可能被汶川地震所延迟触发。b值、地震能量释放率与空间相关距离SCL等地震活动性参数随时间变化扫描结果显示,该区域可能处于不断趋近高应力累积的状态,其未来大震有可能提前发生。西缘地区为应力减小区,其目前的地震活动处于正常水平状态。 | 朱艾斓 解朝娣 徐锡伟 周永胜 Lei Xinglin 王亚丽 | 2010 | 地学前缘2010，17，5： | 10 |
| 10 | 潮汐应力对2007年M_s6.4宁洱地震震源断层成核失稳过程的影响显示文摘在潮汐库仑破裂应力计算和相关性检验的基础上,采用速率-状态依赖性摩擦本构关系,进行潮汐应力对宁洱地震震源断层成核失稳过程影响的数值模拟研究,并讨论潮汐正应力和潮汐剪应力在潮汐应力触发中的作用,以及应力的振幅和周期振荡性对潮汐触发的影响.结果发现,宁洱地震与潮汐应力之间存在潮汐触发相关性.宁洱地震震源断层的成核过程存在一个转变周期,当潮汐应力周期接近和大于转变周期时,潮汐应力的周期性将直接影响潮汐触发作用的效果.潮汐应力振幅值的增加也有助于潮汐应力对断层地震成核失稳过程的影响,正应力和剪应力振幅值的影响效果差别不大,但是潮汐剪应力比正应力能更迅速的起到潮汐触发作用.潮汐应力触发地震的过程中,主要是正值的潮汐正应力和剪应力对地震起到触发作用,而负值的潮汐应力对断层的影响小于正值的潮汐应力,断层对负的潮汐应力不敏感. | 解朝娣 LEI XingLin 吴小平 付虹 熊子瑶 虎雄林 李莎 | 2015 | 中国科学:地球科学2015，45，9： | 10 |
| 11 | Numerical simulation of aerodynamic interaction for a tilt rotor aircraft in helicopter mode显示文摘A rotor CFD solver is developed for simulating the aerodynamic interaction phenomenon among rotor, wing and fuselage of a tilt rotor aircraft in its helicopter mode. The unsteady Navier–Stokes equations are discretized in inertial frame and embedded grid system is adopted for describing the relative motion among blades and nacelle/wing/fuselage. A combination of multi-layer embedded grid and ‘‘extended hole fringe' technique is complemented in original grid system to tackle grid assembly difficulties arising from the narrow space among different aerodynamic components, and to improve the interpolation precision by decreasing the cell volume discrepancy among different grid blocks. An overall donor cell searching and automatic hole cutting technique is used for grid assembly, and the solution processes are speeded up by introduction of Open MP parallel method. Based on this solver, flow fields and aerodynamics of a tilt rotor aircraft in hover are simulated with several rotor collective angles, and the corresponding states of an isolated rotor and rotor/wing/fuselage model are also computed to obtain reference solution.Aerodynamic interference influences among the rotor and wing/fuselage/nacelle are analyzed,and some meaningful conclusions are drawn. | Ye Liang Zhang Ying Yang Shuo Zhu Xinglin Dong Jun | 2016 | Chinese Journal of Aeronautics2016，29，4： | 10 |
| 12 | Grasping institutional complexity in infrastructure megaprojects through the multi-level governance system: A case study of the Hong Kong-Zhuhai-Macao Bridge construction显示文摘This study analyzes the design and operation of multi-level governance system for the smooth delivery of infrastructure mega-projects with high institutional complexity caused by market transition. From an institutional perspective, this study scrutinizes the structure,elements, and dynamics of the governance system of infrastructure mega-projects and then proposes an integrative framework based on the inductive case study of the Hong Kong-Zhuhai-Macao Bridge mega-project. Multiple evidences of archives, field studies, and interviews related to the case project are triangulated to further analyze the institutional effects, specifically those with government logics and market structures, on the design and operation of the three-level governance system. Results reveal that the co-evolution between governments and markets in China has shaped the vertical levels of the mega-project governance system and has further affected their evolution and operation across various stages of project development. This study contributes to the rapidly emerging research on complex system governance by proposing a systematic model of three-level mega-project governance to enhance the timely delivery of infrastructure megaprojects within budget. | Yi HU Yun LE Xinglin GAO Yongkui LI Mingqiang LIU | 2018 | Frontiers of Engineering Management2018，5，1： | 9 |
| 13 | Effect of yellow rice wine on anti-aging ability in aged mice induced by D-galactose显示文摘The present study is focused on investigation of the health protective effect of yellow rice wine(YRW)in mice and the potential underlying mechanism.Symptoms of aging were induced in mice by using Dgalactose(D-gal),and different doses of YRW(4,8,and 12 mL/kg BW)were orally administrated to D-galtreated mice for a period of six weeks.The in vivo data obtained in the present study preliminary indicated that YRW markedly increased the activity of antioxidant enzymes and reduced the concentration of MDA both in the brain and liver.Furthermore,a forced swim test showed that moderate intake of YRW(8 mL/kg BW)significantly decreased the duration of immobility,reduced the blood content of urea nitrogen and lactic acid,and increased hepatic glycogen storage.Besides,results from the Morris water maze test suggested that YRW significantly reversed cognitive impairment and also alleviated neuroapoptosis in the experimental mice by regulating the gene expressions of Bax/Bcl-2 and caspase-3.The above results indicated YRW has a potential anti-aging effect in mice and provided us certain molecular evidence for this action. | Rong Liu Zukang Fu Fengjie Zhang Qingzhong Mao Chunguang Luan Xinglin Han Jie Xue Deliang Wang Si Qin Feike Hao | 2020 | Food Science and Human Wellness2020，9，2： | 8 |
| 14 | Optimization on cooperative feed strategy for radial–axial ring rolling process of Inco718 alloy by RSM and FEM显示文摘During radial–axial ring rolling process,cooperative strategy of the radial–axial feed is critical for dimensional accuracy and thermo mechanical parameters distribution of the formed ring.In order to improve the comprehensive quality of the ring parts,response surface method(RSM) is employed for the first time to optimize the cooperative feed strategy for radial–axial ring rolling process by combining it with an improved and verified 3D coupled thermo-mechanical finite element model.The feed trajectory is put forward to describe cooperative relationship of the radial–axial feed and three variables are designed based on the feed trajectory.In order to achieve multiobjective optimization,four responses including thermo mechanical parameters distribution and rolling force are proposed.Based on the FEM results,RSM is used to establish a response model to depict the function relationship between the objective response and design variables.Through this approximate model,effects of different variables on ring rolling process are analyzed connectedly and optimal feed strategy is obtained by resorting to the optimal chart specific to a constraint condition. | Zhu Xinglin Liu Dong Yang Yanhui Hu Yang Zheng Yong | 2016 | Chinese Journal of Aeronautics2016，29，3： | 7 |

| 16 | Inhibition of miR-144-3p exacerbates non-small cell lung cancer progression by targeting CEP55显示文摘Increasing evidence has indicated that microRNA dysregulation is closely related to the occurrence and development of cancers.Herein,we investigated the relationship between miR-144-3p&CEP55 expression.We then evaluated the association between miR-144-3p&CEP55 expression,&proliferation,invasion&apoptosis of non-small cell lung cancer[NSCLC]cells.Real-time quantitative PCR results revealed that CEP55 was over-expressed whereas miR-144-3p was underexpressed in NSCLC tissues.CCK-8 assay,wound healing assay,&flow cytometry further revealed that overexpression of miR-144-3p significantly inhibited proliferation&migration,but promoted apoptosis of A549 cells.Conversely,inhibition of miR-144-3p promoted proliferation. | Ming Li Yannan Liu Xinglin Jiang Yuanxin Hang Haiying Wang Hang Liu Zhuo Chen Yubo Xiao | 2021 | Acta Biochimica et Biophysica Sinica2021，53，10： | 7 |
| 17 | A laboratory acoustic emission experiment and numerical simulation of rock fracture driven by a high-pressure fluid source显示文摘In order to improve our understanding of rock fracture and fault instability driven by high-pressure fluid sources, the authors carried out rock fracture tests using granite under a confining pressure of 80 MPa with fluid injection in the laboratory. Furthermore, we tested a number of numerical models using the FLAC^(3D) modeling software to find the best model to represent the experimental results. The high-speed multichannel acoustic emission(AE) waveform recording system used in this study made it possible to examine the total fracture process through detailed monitoring of AE hypocenters and seismic velocity.The experimental results show that injecting high-pressure oil into the rock sample can induce AE activity at very low stress levels and can dramatically reduce the strength of the rock. The results of the numerical simulations show that major experimental results, including the strength, the temporal and spatial patterns of the AE events, and the role of the fluid can be represented fairly well by a model involving(1) randomly distributed defect elements to model pre-existing cracks,(2) random modification of rock properties to represent inhomogeneity introduced by different mineral grains, and(3)macroscopic inhomogeneity. Our study, which incorporates laboratory experiments and numerical simulations, indicates that such an approach is helpful in finding a better model not only for simulating experimental results but also for upscaling purposes. | Xinglin Lei Takahiro Funatsu Shengli Ma Liqiang Liu | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，1： | 6 |
| 18 | Chiral plasmonics and enhanced chiral light-matter interactions显示文摘Chirality, which describes the broken mirror symmetry in geometric structures, exists macroscopically in our daily life as well as microscopically down to molecular levels. Correspondingly, chiral molecules interact differently with circularly polarized light exhibiting opposite handedness(left-handed and right-handed). However, the interaction between chiral molecules and chiral light is very weak. In contrast, artificial chiral plasmonic structures can generate 'super-chiral' plasmonic near-field, leading to enhanced chiral light-matter(or chiroptical) interactions. The 'super-chiral' near-field presents different amplitude and phase under opposite handedness incidence, which can be utilized to engineer linear and nonlinear chiroptical interactions. Specifically,in the interaction between quantum emitters and chiral plasmonic structures, the chiral hot spots can favour the emission with a specific handedness. This article reviews the state-of-the-art research on the design, fabrication and chiroptical response of different chiral plasmonic nanostructures or metasurfaces. This review also discusses enhanced chiral light-matter interactions that are essential for applications like chirality sensing, chiral selective light emitting and harvesting. In the final part, the review ends with a perspective on future directions of chiral plasmonics. | Wei Du Xinglin Wen Davy Gerard Cheng-Wei Qiu Qihua Xiong | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 6 |

| 20 | KEY TECHNOLOGY OF D-INSAR AT X-BAND FOR MONITORING LAND SUBSIDENCE IN MINING AREA AND ITS APPLICATION显示文摘In theory, land subsidence measurement results with high accuracy can be obtained by using the Differential Interferometry Synthetic Aperture Radar(D-InSAR) at X-band. In practice, however, the measuring accuracy of D-InSAR at X-band has been seriously affected by some factors, e.g., decorrelation and high deformation gradient. In this work, the monitoring capability of D-InSAR for coal-mining subsidence is evaluated by using SAR data acquired by TerrraSAR-X system. The SAR image registration method for low coherence image pairs, the denoising phase filter for high noise level interferogram and atmospheric effects mitigation method are the key technical aspects which directly influence the measurement results of D-InSAR at X-band. Thus, a robust image registration method, an improved phase filter method and an atmospheric effects mitigation method are proposed in this paper. The proposed image registration method successfully achieves InSAR coregistration, while the amplitude cross-correlation cannot properly coregister low coherence SAR image pairs. Moreover, the time complexity of the proposed image registration method is obviously slighter than that of the Singular Value Decomposition(SVD) method. The comparing experiment results and the unwrapping phase results show that the improved Goldstein filter is more effective than the original Goldstein filter in noise elimination. The atmospheric influence correction experiment results show that the land subsidence areas with atmospheric influence correction are more clarified than that of without atmospheric influence correction. In summary, the presented methods directly improved the measurement results of D-InSAR at X-band. | Li Xinglin Liu Donglie Song Hongjun Chen Runpu Li Hongyu | 2014 | Journal of Electronics(China)2014，31，5： | 5 |
