| 1 | The research progress on lateral shift of reflected electromagnetic wave at the interface of two conductive media显示文摘In this paper the research status of lateral shift of reflected electromagnetic wave at the interface of conductive media was reviewed, the lateral shift and the lateral delay were analyzed, and the charac-teristic of lateral shift curves varying with the angle of incidence was introduced in detail. For electro-magnetic wave logging, the error correction method of lateral shift was stressed in this paper, the magnitude of measured errors caused by the lateral shift was established. It is noticed that the longer wavelength, the larger error of measured results. With respect to the effect of lateral shift, the problem which still needs to be settled in the measurement of electromagnetic wave, as well as prospects on the further research and applications of lateral shift are described. | LIU FuPing WANG AnLing CHEN Qiang LI RuiZhong CHEN HuiGuo YANG ChangChun | 2008 | Chinese Science Bulletin2008，53，7： | 15 |
| 2 | Ubi1 intron-mediated enhancement of the expression of Bt cry1Ah gene in transgenic maize (Zea mays L.)显示文摘The cry1Ah gene was one of novel insecticidal genes cloned from Bacillus thuringiensis isolate BT8. Two plant expression vectors containing cry1Ah gene were constructed. The first intron of maize ubiqutin1 gene was inserted between the maize Ubiquitin promoter and cry1Ah gene in one of the plant expressing vectors (pUUOAH). The two vectors were introduced into maize immature embryonic calli by microprojectile bombardment, and the reproductively plants were acquired. PCR and Southern blot analysis showed that foreign genes had been integrated into maize genome and inherited to the next generation stably. The ELISA assay to T1 and T2 generation plants showed that the expression of Cry1Ah protein in the construct containing the ubi1 intron (pUUOAH) was 20% higher than that of the intronless construct (pUOAH). Bioassay results showed that the transgenic maize harboring cry1Ah gene had high resistance to the Asian corn borers and the insecticidal activity of the transgenic maize containing the ubi1 intron was higher than that of the intronless construct. These results indicated that the maize ubi1 intron can enhance the expression of the Bt cry1Ah gene in transgenic maize | WANG YueBing LANG Zhihong ZHANG Jie HE KangLai SONG FuPing HUANG DaFang | 2008 | Chinese Science Bulletin2008，53，20： | 15 |
| 3 | Low complexity method for spreading sequence estimation of DSSS signal in non-cooperative communication systems显示文摘It is a necessary step to estimate the spreading sequence of direct sequence spread spectrum (DSSS) signal for blind despreading and demodulation in non-cooperative communications. Two innovative and effective detection statistics are proposed to implement the synchronization and spreading sequence estimation procedure. The proposed algorithm also has a low computational complexity with only linear additions and modifications. Theoretical analysis and simulation results show that the algorithm performs quite well in low SNR environment, and is much better than all the existing typical algorithms with a comprehensive consideration both in performance and computational complexity. | Chang Liang Wang Fuping Wang Zanji | 2009 | Journal of Systems Engineering and Electronics2009，20，1： | 10 |
| 4 | Estimation of inbreeding and identification of regions under heavy selection based on runs of homozygosity in a Large White pig population显示文摘Background: Runs of homozygosity(ROHs) are homozygous segments of the genome where the two haplotypes inherited from the parents are identical. The current availability of genotypes for a very large number of single nucleotide polymorphisms(SNPs) is leading to more accurate characterization of ROHs in the whole genome. Here,we investigated the occurrence and distribution of ROHs in 3,692 Large White pigs and compared estimates of inbreeding coefficients calculated based on ROHs(FROH), homozygosity(FHOM), genomic relationship matrix(FGRM)and pedigree(FPED). Furthermore, we identified genomic regions with high ROH frequencies and annotated their candidate genes.Results: In total, 176,182 ROHs were identified from 3,569 animals, and all individuals displayed at least one ROH longer than 1 Mb. The ROHs identified were unevenly distributed on the autosomes. The highest and lowest coverages of Sus scrofa chromosomes(SSC) by ROH were on SSC14 and SSC13, respectively. The highest pairwise correlation among the different inbreeding coefficient estimates was 0.95 between FROH_totaland FHOM, while the lowest was-0.083 between FGRMand FPED. The correlations between FPEDand FROHusing four classes of ROH lengths ranged from 0.18 to 0.37 and increased with increasing ROH length, except for ROH > 10 Mb. Twelve ROH islands were located on four chromosomes(SSC1, 4, 6 and 14). These ROH islands harboured genes associated with reproduction, muscular development, fat deposition and adaptation, such as SIRT1, MYPN, SETDB1 and PSMD4.Conclusion: FROHcan be used to accurately assess individual inbreeding levels compared to other inbreeding coefficient estimators. In the absence of pedigree records, FROHcan provide an alternative to inbreeding estimates.Our findings can be used not only to effectively increase the response to selection by appropriately managing the rate of inbreeding and minimizing the negative effects of inbreeding depression but also to help detect genomic regions with an effect on traits under selection. | Liangyu Shi Ligang Wang Jiaxin Liu Tianyu Deng Hua Yan Longchao Zhang Xin Liu Hongmei Gao Xinhua Hou Lixian Wang Fuping Zhao | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 10 |
| 5 | Spatial Heterogeneity of Soil Mineral Oxide Components in Depression Between Karst Hills,Southwest China显示文摘In karst regions,the spatial heterogeneity of soil mineral oxides and environmental variables is still not clear.We investigated the spatial heterogeneity of SiO2,Al2O3,Fe2O3,CaO,MgO,P2O5,K2O,and MnO contents in the soils of slope land,plantation forest,secondary forest,and primary forest,as well as their relationships with environmental variables in a karst region of Southwest China.Geostatistics,principal component analysis(PCA),and canonical correlation analysis(CCA)were applied to analyze the field data.The results show that SiO2was the predominant mineral in the soils(45.02%–67.33%),followed by Al2O3and Fe2O3.Most soil mineral oxide components had a strong spatial dependence,except for CaO,MgO,and P2O5in the plantation forest,MgO and P2O5in the secondary forest,and CaO in the slope land.Dimensionality reduction in PCA was not appropriate due to the strong spatial heterogeneity in the ecosystems.Soil mineral oxide components,the main factors in all ecosystems,had greater influences on vegetation than those of conventional soil properties.There were close relationships between soil mineral oxide components and vegetation,topography,and conventional soil properties.Mineral oxide components affected species diversity,organic matter and nitrogen levels. | DU Hu WANG Kelin PENG Wanxia ZENG Fuping SONG Tongqing ZHANG Hao LU Shiyang | 2014 | Chinese Geographical Science2014，24，2： | 9 |
| 6 | Transgenic tobacco plants expressing synthetic Cry1Ac and Cry1Ie genes are more toxic to cotton bollworm than those containing one gene显示文摘Transgenic tobacco plants carrying Cry1Ac, Cry1Ie or both genes were obtained. In the leaves of transgenic plants carrying both genes, the contents of Cry1Ac and Cry1Ie proteins were 0.173% and 0.131% of the total proteins, respectively. Cry1Ac protein content was 0.182% and Cry1Ie protein con- tent was 0.124% of the total proteins in the leaves of transgenic plants containing only one Bt gene. Fresh leaves of transgenic tobacco and wild-type plants were used for the insect bioassay against wild-type and Cry1Ac-resistant cotton bollworm (Helicoverpa armigera). The bioassay results showed that transgenic plants carrying both genes were significantly more toxic to wild-type and Cry1Ac-resistant cotton bollworm than those carrying Cry1Ac or Cry1Ie alone. This study indicates that the higher toxicity of transgenic tobacco plants carrying both genes is caused by the cooperative function of both Bt proteins, thus providing a potential way to delay the development of insect resis- tance to transgenic crops. | LIAN Yun JIA ZhiWei HE KangLai LIU Yundun SONG FuPing WANG BaoMin WANG GuoYing | 2008 | Chinese Science Bulletin2008，53，9： | 7 |
| 7 | Chimeric antigen receptor T (CAR-T) cells expanded with IL-7/IL-15 mediate superior antitumor effects显示文摘Dear Editor,Genetic engineering of T cells to express chimeric antigen receptors(CARs)is an efficient approach for clinical therapy of hematological malignancies(Kuwana et al.,1987;Eshhar et al.,1993;Barrett et al.,2014).The CARs endow T cells with the ability to recognize specific antigens and bind them in an MHC-independent mariner,thereby overcoming some of the mechanisms that mediate tumor immune escape.In addition,by providing co-stimulatory signals,CARs endow T cells with enhanced cytotoxicity and persistence compared with primary T cells.A typical CAR comprises a single-chain variable frag me nt(scFv)derived from a monoclonal an tibody(mAb)for an tige n recog nition and signaling domains for co?activation(Eshhar et al.,1993;Sadelain et al.,2013). | Jianxia Zhou Liyuan Jin Fuping Wang Yuan Zhang Bing Liu Tongbiao Zhao | 2019 | Protein & Cell2019，10，10： | 7 |

| 9 | Au nanoclusters suppress chronic lymphocytic leukaemia cells by inhibiting thioredoxin reductase 1 to induce intracellular oxidative stress and apoptosis显示文摘Chronic lymphocytic leukaemia(CLL) is a rare blood cancer that always relapses as refractory disease and eventually leads to death. To date, therapeutic options for CLL patients are scarce and there is an urgent need to develop novel chemotherapeutics that are both effective and safe. Gold-containing compounds induce a lethal oxidative and endoplasmic reticulum stress response in cultured and primary CLL cells via inhibition of thioredoxin reductase(TrxR). However, traditional gold-containing medicines have revealed side effects during clinical applications. Therefore, safer gold-containing drugs are needed to overcome this challenge. In this study, a novel peptide templated gold cluster Au_(25)Sv_9 was synthesized and its therapeutic effect on CLL cells was evaluated. This nanocluster could induce cell apoptosis in MEC-1 cells in a dose-dependent manner which correlated with the uptake amount of clusters in cells.As expected, increasing intracellular reactive oxidative species(ROS) in MEC-1 cells was exhibited with the increase of cluster dosage. Further analyses demonstrated the underlying mechanism that the nanoclusters suppress the activity of TrxR1, increase the level of intracellular ROS, destroy the mitochondrial membrane potential and finally trigger the mitochondrial apoptotic pathway in MEC-1 cells.Furthermore, the direct interaction between Au_(25)Sv_9 clusters and TrxR1 was confirmed for the first time by isothermal titration calorimetry. These findings explored the preclinical efficacy and potential mechanism of gold clusters in CLL therapy and provided a fundamental reference for the development of other novel gold-containing chemotherapeutics to treat CLL. | Qiong Li Qing Yuan Mohan Zhao Yawen Yao Liang Gao Ru Liu Yaling Wang Yong Gong Fuping Gao Xueyun Cao | 2017 | Science Bulletin2017，62，8： | 5 |
| 10 | Antrodia Cinnamomea ameliorates neointimal formation by inhibiting infl ammatory cell infi ltration through downregulation of adhesion molecule expression in vitro and in vivo显示文摘The increased vascular infl ammation is a key event in the development of atherosclerotic lesions.Antrodia cinnamomea has been shown to promote anticancerogenic activity through decreasing infl ammation.However,the potential role of A.cinnamomea in cardiovascular diseases remains unexplored.Herein,using carotid arterial ligation models,we found that ethanol extract from A.cinnamomea(EEAC)signifi cantly inhibited neointimal hyperplasia in a dose-dependent manner,accompanied with the reduced expression of activated p65 and infl ammatory cytokines.We also show that EEAC ameliorated TNF-α-induced phosphorylation of p65 and pro-infl ammatory cytokine expression in both vascular smooth muscle cells(VSMCs)and macrophages in vitro.Mechanistically,EEAC suppressed expression levels of intercellular adhesion molecule-1(ICAM-1)and vascular cell adhesion molecule(VCAM-1)in VSMCs,which attenuates the ability of monocytes/macrophages adhesion to VSMCs.Furthermore,the expression level of these adhesion molecules and infi ltration of monocytes/macrophages were also decreased in neointimal VSMCs of arteries pretreated with EEAC.Altogether,our results reveal a novel function of A.cinnamomea in suppressing vascular infl ammation upon ligation injury during neointimal formation,likely through inhibition of infl ammatory cell infi ltration via downregulating the adhesion molecules in VSMCs.Thus,A.cinnamomea may offer a pharmacological therapy to slow down disease progression in patients with vascular injury. | Yan Zhang Aijin Ma Hao Xi Ning Chen Rong Wang Chenhui Yang Jinbang Chen Pin Lü Fuping Zheng Wenyi Kang | 2021 | Food Science and Human Wellness2021，10，4： | 4 |
| 11 | Genome-wide identification of RNA editing in seven porcine tissues by matched DNA and RNA high-throughput sequencing显示文摘Background: RNA editing is a co/posttranscriptional modification mechanism that increases the diversity of transcripts, with potential functional consequences. The advent of next-generation sequencing technologies has enabled the identification of RNA edits at unprecedented throughput and resolution. However, our knowledge of RNA editing in swine is still limited.Results: Here, we utilized RES-Scanner to identify RNA editing sites in the brain, subcutaneous fat, heart, liver,muscle, lung and ovary in three 180-day-old Large White gilts based on matched strand-specific RNA sequencing and whole-genome resequencing datasets. In total, we identified 74863 editing sites, and 92.1% of these sites caused adenosine-to-guanosine(A-to-G) conversion. Most A-to-G sites were located in noncoding regions and generally had low editing levels. In total, 151 A-to-G sites were detected in coding regions(CDS), including 94 sites that could lead to nonsynonymous amino acid changes. We provide further evidence supporting a previous observation that pig transcriptomes are highly editable at PRE-1 elements. The number of A-to-G editing sites ranged from 4155(muscle) to 25001(brain) across the seven tissues. The expression levels of the ADAR enzymes could explain some but not all of this variation across tissues. The functional analysis of the genes with tissuespecific editing sites in each tissue revealed that RNA editing might play important roles in tissue function.Specifically, more pathways showed significant enrichment in the fat and liver than in other tissues, while no pathway was enriched in the muscle.Conclusions: This study identified a total of 74863 nonredundant RNA editing sites in seven tissues and revealed the potential importance of RNA editing in tissue function. Our findings largely extend the porcine editome and enhance our understanding of RNA editing in swine. | Yuebo Zhang Longchao Zhang Jingwei Yue Xia Wei Ligang Wang Xin Liu Hongmei Gao Xinhua Hou Fuping Zhao Hua Yan Lixian Wang | 2019 | Journal of Animal Science and Biotechnology2019，10，2： | 4 |
| 12 | Analytical solution of electromagnetic field generated by induction logging tool in a fan-ring slot of drill collar while drilling显示文摘Based on the structural characteristic of metal drill collar for induction logging while drilling, we have given the analytical formulae of lengthways fields Ez and Hz when the tool is located in a fan-ring shaped slot of drill collar by the boundary conditions of electromagnetic field, and derived the other components of electromagnetic field in and out the fan-ring slot from Ez and Hz. In the other intervals of formation, where the drill collar is a solid cylinder, the analytical formulae of field are educed through the method of variable coefficient. The total analytical solutions of field in whole space have been obtained. With the help of the analytical formulae, we have also given numerical examples and analyzed the distributive characteristic of electromagnetic field. From the computational results we find that the secondary scattering field Hz is in a linear relation with the conductivity of stratum. The characteristic of field is very useful for induction logging while drilling, which can be used to measure and analyze the logging responses of the stratum conductivity. This paper sets up a theoretical foundation for us to study the distrbutions of field and to direct the design of logging instruments. | LIU FuPing WANG AnLing YANG ChangChun | 2009 | Science China(Technological Sciences)2009，52，7： | 4 |
| 13 | Applying accurate gradients of seismic wave reflection coefficients (SWRC) to the inversion of seismic wave velocities显示文摘Through solving the Zoeppritz's partial derivative equations, we have obtained accurate partial derivatives of reflected coefficients of seismic wave with respect to Pand S-wave velocities.With those partial derivatives, a multi-angle inversion is developed for seismic wave velocities.Numerical examples of different formation models show that if the number of iterations goes over 10, the relative error of inversion results is less than 1%, whether or not there is interference among the reflection waves.When we only have the reflected seismograms of P-wave, and only invert for velocities of P-wave, the multi-angle inversion is able to obtain a high computation precision.When we have the reflected seismograms of both P-wave and VS-wave, and simultaneously invert for the velocities of P-wave and VS-wave, the computation precisions of VS-wave velocities improves gradually with the increase of the number of angles, but the computation precision of P-wave velocities becomes worse.No matter whether the reflected seismic waves from the different reflection interface are coherent or non-coherent, this method is able to achieve a higher computation precision.Because it is based on the accurate solution of the gradient of SWRCs without any additional restriction, the multi-angle inversion method can be applied to seismic inversion of total angles.By removing the difficulties caused by simplified Zoeppritz formulas that the conventional AVO technology struggles with, the multiangle inversion method extended the application range of AVO technology and improved the computation precision and speed of inversion of seismic wave velocities. | LIU FuPing MENG XianJun XIAO JiaQi WANG YuMei SHEN GuoQiang | 2012 | Science China Earth Sciences2012，55，12： | 3 |
| 14 | Boundary element numerical method for the electric field generated by oblique multi-needle electrodes显示文摘According to the electric potential of oblique multi-needle electrodes (OMNE) in biological tissue, the discrete equations based on the indetermination linear current density were established by the boundary element integral equations (BEIE). The non-uniform distribution of the current flowing from multi-needle electrodes to conductive biological tissues was imaged by solving a set of linear equa- tions. Then, the electric field and potential generated by OMNE in biological tissues at any point may be determined through the boundary element method (BEM). The time of program running and stability of computing method are examined by an example. It demonstrates that the algorithm possesses a quick speed and the steady computed results. It means that this method has an important referenced sig- nificance for computing the field and the potential generated by OMNE in bio-tissue, which is a fast, effective and accurate computing method. | LIU FuPing WANG AnLing WANG AnXuan CAO YueZu CHEN Qiang YANG ChangChun | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，2： | 3 |
| 15 | Effect of the Oxidation Time on Properties of Ceramic Coatings Produced on Ti-6Al-4V by Micro-Arc Oxidation显示文摘Ceramic coatings were prepared on Ti-6AI-4V alloy using ac micro-arc oxidation (MAO) in silicate-hypophosphate solution. Growth regularity and formation mechanism of ceramic coatings were discussed. It was found that during the first stage the growth rate of coatings toward the external surface was larger than that toward substrate and then the coating began to grow mainly towards Ti alloy. When the total coating thickness reaches a certain value, it would no longer increase. In addition, the variations of the composition and microstructure of ceramic coatings according to the depositing time were also investigated with X-ray diffraction (XRD) and scanning electron microscope (SEM).The amount of rutile TiO2 gradually increased, whereas the amounts of the anatase TiO2 and amorphous phases first increased and then decreased slightly. | Zhaohua JIANG, Xuetong SUN, Yanping LI, Fuping WANG and Yandong LU Department of Applied Chemistry, Harbin Institute of Technology, Harbin 150001, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 3 |
| 16 | SARS-CoV-2 spike protein interacts with and activates TLR41显示文摘Dear Editor,Accumulating clinical data suggest the main causes of death by COVID-19 include respiratory failure and the onset of sepsis.1 Importantly,sepsis has been observed in nearly all deceased patients.2,3,4,5 It remains elusive how SARS-CoV-2 infection results in viral sepsis in humans.Toll-like receptor 4(TLR4)mediates anti-gram-negative bacterial immune responses by recognizing lipopolysaccharide(LPS)from bacteria.6 We recently found that SARS-CoV-2 infection provoked an anti-bacterial like response at the very early stage of infection via TLR4.However,the identity of the original trigger initiating these abnormal immune responses during SARS-CoV-2 infection is unknown. | Yingchi Zhao Ming Kuang Junhong Li Ling Zhu Zijing Jia Xuefei Guo Yaling Hu Jun Kong Hang Yin Xiangxi Wang Fuping You | 2021 | Cell Research2021，31，7： | 3 |
| 17 | Design of Intelligent Irrigation Monitoring System Based on GPRS and Zigbee显示文摘In order to solve the present dual contradiction of the low utilization of water resources in China's agricultural sector and the low land management efficiency,using Zigbee wireless sensor network and GPRS technology,this paper designs an intelligent monitoring system based on the GPRS and Zigbee wireless network technology. The Zigbee wireless sensor network is established based on the IEEE 802. 15. 4 / Zigbee protocol,consisting of terminal node for capturing and transmitting soil and environmental information to the coordinator node( gateway node)or acting the control command from the GPRS network. The irrigation remote monitoring network layer consists of coordinator node connected by the TCP / IP protocol,which can implement the precision irrigation of crops and the information management of arable land to the monitor center or user. And the monitor center using Java to write the system is safe and effective. | Fuping WANG Panpan FENG | 2015 | Asian Agricultural Research2015，7，6： | 2 |
| 18 | Dendrite growth and micromechanical properties of rapidly solidified ternary Ni-Fe-Ti alloy显示文摘The rapid solidification of undercooled liquid Ni_(45)Fe_(40)Ti_(15)alloy was realized by glass fluxing technique.The microstructure of this alloy consists of primaryγ-(Fe,Ni)phase and a small amount of interdendritic pseudobinary eutectic.The primaryγ-(Fe,Ni)phase transferred from coarse dendrite to fragmented dendrite and the lamellar eutectic became fractured with the increase of undercooling.The growth velocity ofγ-(Fe,Ni)dendrite increased following a power relation with the rise of undercooling.The addition of solute Ti suppressed the rapid growth ofγ-(Fe,Ni)dendrite,as compared with the calculation results of Fe-Ni alloy based on LKT model.The microhardness values of the alloy and the primaryγ-(Fe,Ni)phase increased by 1.5 times owing to the microstructural refinement caused by the rapid dendrite growth.The difference was enlarged as undercooling increases,resulting from the enhanced hardening effects on the alloy from the increased grain boundaries and the second phase. | Ying Ruan Haizhe Zhu Qingqing Wang Fuping Dai Delu Geng Bingbo Wei | 2017 | Progress in Natural Science:Materials International2017，27，5： | 2 |
| 19 | Jacobian matrix for the inversion of P-and S-wave velocities and its accurate computation method显示文摘The optimization inversion method based on derivatives is an important inversion technique in seismic data processing,where the key problem is how to compute the Jacobian matrix.The computation precision of the Jacobian matrix directly influences the success of the optimization inversion method.Currently,all AVO(Amplitude Versus Offset) inversion techniques are based on approximate expressions of Zoeppritz equations to obtain derivatives.As a result,the computation precision and application range of these AVO inversions are restricted undesirably.In order to improve the computation precision and to extend the application range of AVO inversions,the partial derivative equation(Jacobian matrix equation(JME) for the P-and S-wave velocities inversion) is established with Zoeppritz equations,and the derivatives of each matrix entry with respect to Pand S-wave velocities are derived.By solving the JME,we obtain the partial derivatives of the seismic wave reflection coefficients(RCs) with respect to P-and S-wave velocities,respectively,which are then used to invert for P-and S-wave velocities.To better understand the behavior of the new method,we plot partial derivatives of the seismic wave reflection coefficients,analyze the characteristics of these curves,and present new understandings for the derivatives acquired from in-depth analysis.Because only a linear system of equations is solved in our method,the computation of Jacobian matrix is not only of high precision but also is fast and efficient.Finally,the theoretical foundation is established so that we can further study inversion problems involving layered structures(including those with large incident angle) and can further improve computational speed and precision. | LIU FuPing MENG XianJun WANG YuMei SHEN GuoQiang YANG ChangChun | 2011 | Science China Earth Sciences2011，54，5： | 2 |
| 20 | Characteristics of Recent Horizontal Crustal Movement and Tectonic Deformation in the Northwest China Region显示文摘Making use of observation data of GPS in the Northwest China region and infrared distance-measurements crossing the Qilian-Longshoushan fault zone up to 2004, aided by the least square collocation and inversion of negative dislocation model for the boundaries of elastic blocks and the singular force-source, the dynamic evolution features of deformation and strain fields before and after the M_S=8.1 earthquake on the west of Kunlun Mountains Pass, especially the recent tectonic deformation and stress field status three years after this earthquake are studied. The possible regions or segments of active blocks and their boundaries reflecting accumulation background of high strain energy of producing earthquakes over middle magnitude, are obtained, as well as the potential epicenter. The results show that after short-term relaxation and adjustment in the northern margin of Qinghai-Xizang (Tibet) block after the M_S=8.1 earthquake, the main control action of background field of northeastward pushing of Indian plate is now recovering. Moreover, the following regions are found to have the background of high strain energy accumulation. They are the middle segment of the northern Tianshan fault zone and its meeting region with the western segment, the middle and western segments of southern Tianshan fault zone and the meeting region with Western Kunlun fault zone, the middle segment of Altun fault, the middle-eastern segment of Qilianshan fault zone and its meeting region with Haiyuan fault, the meeting region of northern margin fault of west Qinling Range and the southeastward expanding line of Zhuanglanghe fault; The Linze and Haiyuan areas also see accumulation of strain energy to some degree. | Zhang Xi Liu Wenyi Wang Shuangxu Wang Wenping Zhang Xiaoliang Cui Duxin Xue Fuping | 2006 | Earthquake Research in China2006，20，3： | 2 |
