| 1 | The P-wave velocity structure of the lithosphere of the North China Craton——Results from the Wendeng-Alxa Left Banner deep seismic sounding profile显示文摘For the first time on the Chinese mainland, long-range wide-angle seismic reflection/refraction profiling technology has been applied to seismic wave phases from different depths and with different attributes within the various blocks of the North China Craton to characterize the structure of the crust and upper mantle lithosphere. By comparative analysis of the seismic wave phase characteristics in each block across a 1500-km-long east-west profile, we have identified conventional Pg, Pci, PmP and Pn phases in the crust, made a clear contrast between PL1 and PL2 waves belonging to two groups of lithospheric-scale phases, and produced a model of crust-mantle velocity structures and tectonic characteristics after one- and two-dimensional calculations and processing. The results show that the thickness of the crust and lithosphere gradually deepens from east to west along the profile. However, at the reflection/refraction interface, seismic waves in each group show obvious localized changes in each block. Also, the depth to the crystalline basement changes greatly, from as much as 7.8 km in the North China fault basin to only about 2 km beneath the Jiaodong Peninsula and Taihang-Lüliang area. The Moho morphology as a whole ranges from shallow in the east to deep in the west, with the deepest point in the Ordos Block at 47 km; in contrast, the North China Plain Block is uplifting. The L1 interface of the lithosphere is observed only to the west of Taihang Mountains, at a relatively slowly changing depth of about 80 km. The L2 interface varies from 75 to 160 km and shows a sharp deepening to the west of Taihang Mountains, forming a mutation belt. | WANG ShuaiJun WANG FuYun ZHANG JianShi JIA ShiXu ZHANG ChengKe ZHAO JinRen LIU BaoFeng | 2014 | Science China Earth Sciences2014,57,9: | 26 |
| 2 | Three-dimensional crustal velocity structure model of the middle-eastern north China Craton (HBCrust1.0)显示文摘Lithosphere thinning and destruction in the middle-eastern North China Craton(NCC), a region susceptible to strong earthquakes, is one of the research hotspots in solid earth science. All 42 seismic wide-angle reflection/refraction profiles have been completed in the middle-eastern NCC. We collect all the 2-D profiling results and perform gridding of the velocity and interface depth data, building a 3-D crustal velocity structure model for the middle-eastern NCC, named HBCrust1.0, by using the Kriging interpolation method. Our result shows that the first-arrival times calculated by HBCust1.0 fit well with the observations. The result demonstrates that the upper crust is the main seismogenic layer, and the brittle-ductile transition occurs at depths near interface C(the interface between upper and lower crust). The depth of interface Moho varies beneath the source area of the Tangshan earthquake, and a low-velocity structure is found to extend from the source area to the lower crust. Based on these observations, it can be inferred that stress accumulation responsible for the Tangshan earthquake may have been closely related to the migration and deformation of the mantle materials. Comparisons of the average velocities of the whole crust, the upper and the lower crust show that the average velocity of the lower crust under the central part of the North China Basin(NCB) in the east of the craton is obviously higher than the regional average. This high-velocity probably results from long-term underplating of the mantle magma. | DUAN YongHong WANG FuYun ZHANG XianKang LIN JiYan LIU Zhi LIU BaoFeng YANG ZhuoXin GUO WenBin WEI YunHao | 2016 | Science China Earth Sciences2016,59,7: | 24 |
| 3 | Deep seismic sounding data reveal the crustal structures beneath Zoigê basin and its surrounding folded orogenic belts显示文摘Songpan-Garze massif is located at the turning position of tectonics from the nearly west-east direction to the nearly north-south direction in the northeastern margin of Tibetan Plateau,with Zoigê basin in the centre of the massif.In this paper,we build a crustal structure model of Zoigê basin and its surrounding folded orogenic belts using the deep seismic sounding data in this region.We also discuss structures and properties of the basement in Zoigê basin,tectonic relations between Zoigê upland basin and its surrounding folded orogenic belts,crustal deformation and thickening in the northeastern margin of Tibetan Plateau,and decoupling and relaxing processes in the crust.The results indicate that a special 'Mesozoic basement' is formed of Triassic rocks with high density (2.65-2.75 g/cm3) and high velocity (5.6 km/s) in Zoigê basin.Songpan-Garze tectonic massif was transformed into two types of tectonic units with different crustal structures,i.e.,relatively stable Zoigê upland basin and active folded orogenic belts around the basin,in the course of the crustal material of Tibetan Plateau flowing eastward and obstructed by surrounding stable blocks.The thickening of the crust in the northeastern margin of Tibetan Plateau mainly occurred in the mid and lower crust,and the structure characterized by low velocities and multiple reflectors obviously appears in the folded orogenic belts around Zoigê basin.It implies that the mid and lower crust underwent a strong tectonic deformation in the folded orogenic areas.The thickness of the crust is about 50 km in Zoigê basin and the folded orogenic belts at the both southern and northern sides of Zoigê basin.The 'Mountain root' cannot be identified.It is inferred that during the later orogenic period the eastwards flowing deep materials moved clockwise along the relatively relaxing southern side around the eastern tectonic knot under the obstructing of surrounding rigid massifs,and it resulted in the strong stretching action of the folded orogenic belts around Zoigê basin. | JIA ShiXu,ZHANG XianKang,ZHAO JinRen,WANG FuYun,ZHANG ChengKe,XU ZhaoFan,PAN JiShun,LIU Zhi,PAN SuZhen & SUN GuoWei Geophysical Exploration Center,China Earthquake Administration,Zhengzhou 450002,China | 2010 | Science China Earth Sciences2010,53,2: | 11 |
| 4 | North China sub-craton lithospheric structure elucidated through coal mine blasting显示文摘We present a super-range seismic observation along the >1300-km-long profile passing through the Yinchuan basin and the Ordos block from the blasting point towards the southeast triggered by a large-(dynamite) scale coal blast in the Ningxia Hui Autonomous Region's Helan Mountain (yielded a profile). The seismic wave information from the uppermost mantle reflecting different depths was obtained by the China continental seismic survey. Pn refracted waves from the uppermost mantle were effectively traced up to 500 km and beyond. The stable dynamic and kinematic characteristics of the Pn wave-group indicate that the uppermost mantle below the Ordos block is a gently changing structure with a weak positive gradient. If Pm1, Pm2 waves are considered as the wave groups from the upper mantle, there may be distinct structural strata in the upper-mantle structures with average velocities of 7.70―7.80 km/s and 8.10―8.20 km/s, respectively. Based on the travel-time curve feature of Pm1, Pm2 waves, there may be a certain layer with a reverse velocity between the M1 and M2 interfaces. The depth range indicated by them is about 110―120 km and 200―220 km. These phenomena basically reflect the structural features of the upper-mantle lithosphere in this region. The information obtained may provide meaningful references for surveying North China craton lithospheric structures, as well as under-standing the shapes and structures of different spherical layers within the upper-mantle. | ZHAO JinRen ZHANG XianKang WANG FuYun ZHANG ChengKe ZHANG JianShi LIU BaoFeng PAN SuZhen | 2009 | Chinese Science Bulletin2009,54,4: | 7 |
| 5 | Design and field tests of a deck-extension bridge with small box girder显示文摘A jointless bridge could fundamentally eliminate vulnerable deck joints, thereby meeting the need for sustainable development of bridges, especially for an expressway with highspeed traffic. In this paper, one jointless bridge(deck-extension bridge) with a small box girder in an expressway was chosen as a case study to examine the structural design,construction and field test. The field tests of the bridge indicated that the designed and constructed structures can satisfy the requirement for service performance of the deckextension bridge. Some key technologies, such as the position of longitudinal reinforcements in the superstructure-approach slab connections and the arrangement of the sliding material layers, were introduced. The longitudinal thermal movement of the superstructure in the deck-extension bridge with a small box girder could be predicted accurately by using the average temperature of the cross section of a small box girder. The finite element model, built by using the MIDAS program, was used to analyze the temperature distribution on the cross section of a small box girder, the accuracy of which could be verified by comparing with the measured values. The maximum longitudinal thermal movement of the superstructure in deck-extension bridges with a small box girder under historically extreme temperature conditions was predicted. | Junqing Xue Bruno Briseghella Jianhui Lin Fuyun Huang Baochun Chen | 2018 | Journal of Traffic and Transportation Engineering(English Edition)2018,5,6: | 7 |
| 6 | Effect of miniscalpel-needle on relieving the pain of myofascial pain syndrome: a systematic review显示文摘OBJECTIVE: To evaluate the effect and safety of miniscalpel-needle(MSN) on reducing the pain of myofascial pain syndrome(MPS).METHODS: We reviewed the available literatures inception up to February 2014 using Pubmed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure Database, Chinese Biomedical Database and Wanfang Database.RESULTS: Eight randomized controlled trials were finally identified. The main controls involved acupuncture, medications, injection, massage and cupping. We found that all of the studies agreed on the potential benefit of MSN as a strategy for MPS and the superiority compared to the controls, however,randomized methods applied in most of the trials could be criticized for their high or unclear risk of bias. Further research is also needed to clarify questions around the appropriate frequency and number of treatment sessions of MSN.CONCLUSION: This review shows that MSN might have the effect on MPS, even though there were some limitations in the studies included in the review. Studies with robust methodology are warranted to further test its pain-relieving effect on MPS. | Liu Tong Peng Yuanyuan Zhu Shipeng Chen Huan Li Fuyun Hong Peixin Cao Bingyan Peng Bo Fan Yifan Chen Yupei Zhang Li | 2015 | Journal of Traditional Chinese Medicine2015,35,6: | 6 |
| 7 | Assessment of blood and oxygen delivery to flaps of rhesus using near infrared steady-state spectroscopy显示文摘Near infrared spectroscopy has been considered as a potentially ideal noninvasive technique for the postoperative monitoring of plastic surgery. In this study, 6 flaps were raised on rhesus monkeys’ forearms. Blood and oxygen delivery to these flaps was monitored following vascular occlusions and inhalation of pure oxygen. Optical fibers were adopted in the probe of the oximeter so that the cutaneous detection could be performed in reflectance mode. Different and repeatable patterns of changes were measured following vascular occlusions on flaps. It is clear that the near infrared spectroscopy is capable of postoperatively monitoring vascular problems in flaps, especially the venous problem. Near infrared spectroscopy showed high sensitivity to detect the dynamic changes in flaps induced by inhalation of pure oxygen in this study. The experimental results indicated that it was potential to assess tissue viability utilizing the dynamic changes induced by some noninvasive stimulation (such as inhaling | TIAN Fenghua DING Haishu CAI Zhigang WANG Guangzhi ZHAO Fuyun | 2002 | Chinese Science Bulletin2002,47,21: | 6 |
| 8 | Shaking table test and numerical simulation of an isolated cylindrical latticed shell under multiple-support excitations显示文摘In order to study the infl uence of the ground motion spatial eff ect on the seismic response of large span spatial structures with isolation bearings, a single-layer cylindrical latticed shell scale model with a similarity ratio of 1/10 was constructed. An earthquake simulation shaking table test on the response under multiple-support excitations was performed with the high-position seismic isolation method using high damping rubber (HDR) bearings. Small-amplitude sinusoidal waves and seismic wave records with various spectral characteristics were applied to the model. The dynamic characteristics of the model and the seismic isolation eff ect on it were analyzed at varying apparent wave velocities, namely infi nitely great, 1000 m/s, 500 m/s and 250 m/s. Besides, numerical simulations were carried out by Matlab software. According to the comparison results, the numerical results agreed well with the experimental data. Moreover, the results showed that the latticed shell roof exhibited a translational motion as a rigid body after the installation of the HDR bearings with a much lower natural frequency, higher damping ratio and only 1/2~1/8 of the acceleration response peak values. Meanwhile, the structural responses and the bearing deformations at the output end of the seismic waves were greatly increased under multiple-support excitations. | Xue Suduo Shan Mingyue Li Xiongyan Liang Shuanzhu Huang Fuyun Liu Yi | 2019 | Earthquake Engineering and Engineering Vibration2019,18,3: | 5 |
| 9 | Mechanisms and Effects on HBV Replication of the Interaction between HBV Core Protein and Cellular Filamin B显示文摘Hepatitis B virus(HBV) infection is one of the major problems that threatens global health. There have been many studies on HBV, but the relationship between HBV and host factors is largely unexplored and more studies are needed to clarify these interactions. Filamin B is an actin-binding protein that acts as a cytoskeleton protein, and it is involved in cell development and several signaling pathways. In this study, we showed that filamin B interacted with HBV core protein,and the interaction promoted HBV replication. The interaction between filamin B and core protein was observed in HEK293T, Huh7 and HepG2 cell lines by co-immunoprecipitation and co-localization immnofluoresence. Overexpression of filamin B increased the levels of HBV total RNAs and pre-genome RNA(pg RNA), and improved the secretion level of hepatitis B surface antigen(HBsAg) and hepatitis B e antigen(HBeAg). In contrast, filamin B knockdown inhibited HBV replication, decreased the level of HBV total RNAs and pgRNA, and reduced the secretion level of HBsAg and HBeAg. In addition, we found that filamin B and core protein may interact with each other via four blocks of argentine residues at the C-terminus of core protein. In conclusion, we identify filamin B as a novel host factor that can interact with core protein to promote HBV replication in hepatocytes. Our study provides new insights into the relationship between HBV and host factors and may provide new strategies for the treatment of HBV infection. | Yilin Li Yishuang Sun Fuyun Sun Rong Hua Chenlin Li Lang Chen Deyin Guo Jingfang Mu | 2018 | Virologica Sinica2018,33,2: | 3 |
| 10 | Estimating the site effects in Luoyang basin using horizontal-to-vertical spectral ratio method from a short-period dense array显示文摘The influence of local site effects on seismic ground motions is an important issue in seismic hazard assessment and earthquake resistant design. Determining site effects in densely populated cities built on basins can help to reduce the earthquake hazard. Site effects of Luoyang basin are estimated by the horizontal-to-vertical spectral ratio(HVSR) method using ambient noise records from a short-period dense array. The sites in Luoyang basin are sorted into three types according to the pattern of the HVSR curves. There are cases with a single clear peak, two clear peaks, and an unclear low frequency peak or multiple peaks, which correspond to there being one large impedance contrast interface, two large interfaces, and a moderate one beneath the sites, respectively. The site effects characterized by fundamental frequency from HVSR curves are affected by underlying sedimentary layers and depth of sedimentary basement. According to our results, the existence of thick sediment layer obviously lowers the fundamental frequency to the period range from 2 to 4 s in the downtown area of Luoyang city. The ground motion will amplify when through the sites and the buildings with height of 20–50 floors can resonate at the similar frequency domain. Site effects estimation using HVSR method from a short-period dense array is an effective technique in areas of moderate seismic risk where strong motion recordings are lacking, such as the Luoyang basin. | Yujuan Tan Yunhao Wei Yonghong Duan Fuyun Wang | 2018 | Earthquake Science2018,31,5: | 3 |
| 11 | Three-dimensional crustal P-wave velocity structure in the Yangbi and Eryuan earthquake regions, Yunnan, China显示文摘A magnitude 5.5 earthquakes occurred in Eryuan County,Dali Bai Autonomous Prefecture,Yunnan Province,China,on March 3.And a magnitude 5.0 earthquake occurred in the same place on April 17,2013,i.e.,45 days later.Then,on May 21,2021,multiple earthquakes,one with magnitude 6.4 and several at 5.0 or above,occurred in Yangbi County,Dali Bai Autonomous Prefecture,Yunnan Province,China.All of these occurred in the Weixi-QiaohouWeishan fault zone.In this study,1,874 seismic events in Yangbi and Eryuan counties were identified by automatic micro-seismic identification technology and the first arrivals were picked up manually.Following this,a total of 11,968 direct P-wave absolute arrivals and 73,987 high-quality Pwave relative arrivals were collected for joint inversion via the double difference tomography method.This was done to obtain the regional three-dimensional fine crustal P-wave velocity structure.The results show that the travel time residuals before and after inversion decreased from the initial–0.1–0.1 s to–0.06–0.06 s.The upper crust in the study area,which exhibited a low-velocity anomaly,corresponded to the basin region;this indicated that the low-velocity anomaly in the shallow part of the study area was affected by the basin.Results also showed some correlation between the distribution of the earthquakes and velocity structure,as there was a lowvelocity body Lv1 with a wide distribution at depths ranging from 15–20 km in the Yangbi and Eryuan earthquake regions.In addition,earthquakes occurred predominantly in the highlow velocity abnormal transition zone.The low-velocity body in the middle and lower crust may be prone to concentrating upper crustal stress,thus leading to the occurrence of earthquakes. | Jia Jia Qingju Wu Fuyun Wang | 2021 | Earthquake Science2021,34,4: | 3 |
| 12 | Shallow velocity structure of the Luoyang basin derived from dense array observations of urban ambient noise显示文摘Determining the shallow structure of a sediment basin is important when evaluating potential seismic hazards given that such basins can significantly amplify seismic energy. The Luoyang basin is located in the western He'nan uplift and is a Meso-Cenozoic depression basin. To characterize the shallow structure of the basin, we develop a model of the shallow high-resolution three-dimensional(3D)shear-wave velocity structure of the basin by applying ambient noise tomography to a dense array of 107 portable digital seismometers deployed over the basin. More than 1,400 Rayleigh-wave dispersion curves for periods in the range 0.5–5 s are extracted. The 3D variations of shear-wave velocity in the shallow crust are inverted using a direct surface-wave tomographic method with period-dependent ray tracing, with all the surface-wave group-velocity dispersion data being inverted simultaneously. The results show that in the shallow crust of the study area, the velocity distribution corresponds to surface geology and geological features. The Luoyang basin exhibits a low shear-wave velocity feature that is consistent with the distribution of sediment in the region,while the Xiongershan and Songshan uplifts exhibit higher shear-wave velocity structures. The results provide a shallow high-resolution 3D velocity model that can be used as a basis for simulation of strong ground motion and evaluation of potential seismic hazards. | Ming Zhou Xiaofeng Tian Fuyun Wang Yunhao Wei Hailiang Xin | 2018 | Earthquake Science2018,31,5: | 2 |
| 13 | Joint inversion of gravity and seismic data along a profile across the seismogenic fault of 2010 Yushu Ms7. 1 earthquake显示文摘Yushu Ms7. 1 earthquake occurred on the Ganzi-Yushu fault zone,across which we carried out a joint relative-gravity and seismic-reflection survey,and then performed a gravity inversion constrained by the seismic-reflection result. Based on the data of complete Bouguer gravity anomaly and seismic reflection,we obtained a layered interface structure in deep crust down to Moho. Our study showed that the inversion could reveal the interfaces of strata along the survey profile and the directions of regional faults in two-dimension. From the characteristics of the observed topography of the Moho basement,we tentatively confirmed that the uplift of eastern edge of Qinghai-Tibet plateau was caused by the subduction of the Indian plate. | Yang Guangliang Wang Fuyun Shen Chongyang Sun Shaoan Tan Hongbo | 2011 | Geodesy and Geodynamics2011,2,4: | 2 |

| 15 | Fabrication and characterization of squama-shape micro/nano multi-scale silicon material显示文摘This paper presents the fabrication of squama-shape micro/nano multi-scale structures and the analysis of the interaction among different-scale structures during the fabrication processes. Well-designed microstructures made of inverted pyramids and V-shape grooves are fabricated by KOH wet etching. High-dense high-aspect-ratio (HAR) nanostructures are fabricated atop microstructures by an improved maskless deep reactive ion etching (DRIE) process, with an optimized recipe to form micro/nano dual-scale structures (MNDS). Due to the impact of the profile of microstructures on the shape of nanostructures, dissymmetrical (i.e., squama-shape) nanopillars have been formed on the inclined surfaces of microstructures, while the symmetrical nanopillars are formed on the horizontal surfaces with different formation velocities. Furthermore, the optical properties of MNDS are not sensitive to structural parameters of microstructures, making the sample overcome the lithography limitation of conventional processes for photo-devices. Eventually, three-level structures are fabricated by sputtering a gold thin film on the MNDS, and the profile of MNDS is selective in the deposition of gold particles, which is very useful for practical applications. | ZHANG XiaoSheng ZHU FuYun SUN GuangYi ZHANG HaiXia | 2012 | Science China(Technological Sciences)2012,55,12: | 2 |
