| 1 | SHRIMP U-Pb zircon age of tuff from the Kunyang Group in central Yunnan:Evidence for Grenvillian orogeny in South China显示文摘Whether or not Grenvillian orogeny occurred in South China still remains highly controversial because high-quality,discriminating data are lacking,and therefore,the key to resolve this matter is to find datable volcanic and/or sedimentary rocks related to Grenvillian orogeny. Such rocks are apparently present in the Fuliangpeng Member from the lower-middle part of Kunyang Group in central Yunnan; here the unit is more than 100 m thick and consists of andesitic ignimbrite,tuffite,terrigeous clastic rocks and carbonates. These volcanic rocks,developed south of the Sibao fold-thrust belts,represent the earliest calc-alkaline volcanic activity in late Precambrian time from central Yunnan and are coeval with both a change in sedimentary facies from detritus to carbonates and the beginning of seismite development elsewhere. Two samples for SHRIMP analysis were collected from this volcanic unit. Sample G3-29-2,from the bottom of Fuliangpeng Member,is an ignimbrite,and about 100 zircon crys-tals recovered from it have euhedral shapes and display relatively simple sector zonation under cathodoluminescent (CL) imaging,suggesting a magmatogenic origin. Twenty-five of the zircons were analyzed and a weighed-mean U-Pb age of 1032±9 Ma was obtained. Sample G3-29-3 from uppermost part of Fuliangpeng Member is a tuffite,and many rounded,evidently detrital zircons were recovered. Nine of these zircons were analyzed,and the oldest single-grain U-Pb zircon age is 1938±26 Ma,im-plying that Paleoproterozoic basement developed in Cathaysia. The dating result,combined with the geotectonic research on the Fuliangpeng Member,leads us to conclude that late Mesoproterozoic orogenic volcanic activity occurred in the western part of South China,and that the related collision of Yangtze and Cathaysian cratons was an integral part of the assembly of Rodinia. | ZHANG ChuanHeng GAO LinZhi WU ZhenJie SHI XiaoYing YAN QuanRen LI DaJian | 2007 | Chinese Science Bulletin2007，52，11： | 35 |
| 2 | Earthquake-induced soft-sediment deformation structures in the Mesoproterozoic Wumishan Formation,North China,and their geologic implications显示文摘Soft-sediment structures are key to defining seismites. Two soft-sediment deformation horizons, bounded by undeformed carbonate strata, have been found in the Wumishan Formation in the Jumahe region, 175 km southwest of Beijing. One is in the lowest part of Wumishan Formation; and the other is in the uppermost part of Litho-member I. The soft-sediment structures in these two horizons fall into three categories: mould-and-sag structures, hydraulic shatterings and liquefaction dikes. The mould-and-sag structures are divided into two types: one developed in tidal-flat sediments, accompa-nied by many liquefaction-related structures and characterized by autochthonous post-earthquake sediments in sags, and the other type developed in deep-water environments, is not associated with liquefaction structures, and is overlain immediately by seismogenic tsunamites. The hydraulic shat-terings are composed of pockets of fluidization conglomerate, sand intrusions, and syndepositional faults. The liquefaction dikes fall into two categories: hydraulic-fracturing dikes and lateral-spreading dikes. The former are steep, planar, and pinch out upwards. The latter are snake-like and characterized by no diapir-related drag structures in surrounding rocks. Examination of the attitudes and strati-graphic positions of these structures suggests that these soft-sediment structures are seismogenic, and consequently, are seismites. Most seismites in the Wumishan Formation are developed near the former western, margin fault of Yanliao rift. This occurrence suggests that they could be related to movements on this fault. Other geological implications are discussed. | ZHANG ChuanHeng WU ZhengJie GAO LinZhi WANG Wei TIAN YanLin MA Chao | 2007 | Science China Earth Sciences2007，50，3： | 15 |
| 3 | Fabrication and Testing of Carbon Fiber Reinforced Truss Core Sandwich Panels显示文摘Truss core sandwich panels reinforced by carbon fibers were assembled with bonded laminate facesheets and carbon fiber reinforced truss cores.The top and bottom facesheets were interconnected with truss cores.Both ends of the truss cores were embedded into four layers of top and bottom facesheets.The mechanical properties of truss core sandwich panels were then investigated under out-of-plane and in-plane compression loadings to reveal the failure mechanisms of sandwich panels.Experimental results indicated that the mechanical behavior of sandwich structure under in-plane loading is dominated by the buckling and debonding of facesheets. | Bing Wang Linzhi Wu Li Ma Qiang Wang Shanyi Du | 2009 | Journal of Materials Science & Technology2009，25，4： | 10 |
| 4 | High-Resolution Genome-wide Association Study Identifies Genomic Regions and Candidate Genes for Important Agronomic Traits in Wheat显示文摘Wheat(Triticum aestivum)is a major staple food crop worldwide.Genetic dissection of important agronomic traits is essential for continuous improvement of wheat yield to meet the demand of the world's growing population.We conducted a large-scale genome-wide association study(GWAS)using a panel of 768 wheat cultivars that were genotyped with 327609 single-nucleotide polymorphisms generated by genotyping-by-sequencing and detected 395 quantitative trait loci(QTLs)for 12 traits under 7 environments.Among them,273 QTLs were delimited to≤1.0-Mb intervals and 7 of them are either known genes(Rht-D,Vrn-B1,and Vrn-D1)that have been cloned or known QTLs(TaGA2ox8,APO1,TaSus1-7B,and Rht12)that were previously mapped.Eight putative candidate genes were identified for three QTLs that enhance spike seed setting and grain size using gene expression data and were validated in three bi-parental populations.Protein sequence analysis identified 33 putative wheat orthologs that have high identity with rice genes in QTLs affecting similar traits.Large r^2 values for additive effects observed among the QTLs for most traits indicated that the phenotypes of these identified QTLs were highly predictable.Results from this study demonstrated that significantly increasing GWAS population size and marker density greatly improves detection and identification of candidate genes underlying a QTL,solidifying the foundation for large-scale QTL fine mapping,candidate gene validation,and developing functional markers for genomics-based breeding in wheat. | Yunlong Pang Chunxia Liu Danfeng Wang Paul St.Amand Amy Bernardo Wenhui Li Fang He Linzhi Li Liming Wang Xiufang Yuan Lei Dong Yu Su Huirui Zhang Meng Zhao Yunlong Liangi Hongze Jia Xitong Shen Yue Lu Hongming Jiang Yuye Wu Anfei Li Honggang Wang Lingrang Kong Guihua Bai Shubing Liu | 2020 | Molecular Plant2020，13，9： | 8 |

| 6 | The transient fracture behavior for a functionally graded layered structure subjected to an in-plane impact load显示文摘The transient fracture behavior of a functionally graded layered structure subjected to an in-plane impact load is investigated. The studied structure is composed of two homogeneous layers and a functionally graded interlayer with a crack perpendicular to the boundaries. The impact load is applied on the face of the crack. Fourier transform and Laplace transform methods are used to formulate the present problem in terms of a singular integral equation in Laplace transform domain. Considering variations of parameters such as the nonhomogeneity constant, the thickness ratio and the crack length, the dynamic stress intensity factors (DSIFs) in time domain are studied and some meaningful conclusions are obtained. | Licheng Guo Linzhi Wu Yuguo Sun Li Ma | 2005 | Acta Mechanica Sinica2005，21，3： | 5 |
| 7 | NUMERICAL SIMULATION OF CRACK GROWTH IN BRITTLE MATRIX OF PARTICLE REINFORCED COMPOSITES USING THE XFEM TECHNIQUE显示文摘Crack growth in particle reinforced composites is significantly influenced by the character of the reinforcement particles.To accurately deal with such problems,the extended finite element method (XFEM) was employed and improved.The simulations are accomplished by using a new domain expression of an interaction integral for evaluating stress intensity factors (SIFs),and by adopting the maximum hoop stress criterion for crack-growth direction prediction.Crack deflection/attraction mechanisms and their associated energy release rate variations are investigated.It is shown that the applied numerical method allows a considerable flexibility and can be used in more general situations.The crack-tip shielding and amplifying behaviors are clearly observed. | Zhiyong Wang Li Ma Linzhi Wu Hongjun Yu | 2012 | Acta Mechanica Solida Sinica2012，25，1： | 4 |
| 8 | Geometric and material nonlinearities of sandwich beams under static loads显示文摘A new theory developed from extended high-order sandwich panel theory(EHSAPT)is set up to assess the static response of sandwich panels by considering the geometrical and material nonlinearities simultaneously.The geometrical nonlinearity is considered by adopting the Green-Lagrange-type strain for the face sheets and core.The material nonlinearity is included as a piecewise function matched to the experimental stress-strain curve using a polynomial fitting technique.A Ritz technique is applied to solve the governing equations.The results show that the stress stiffening feature is well captured in the geometric nonlinear analysis.The effect of the geometric nonlinearity in the face sheets on the displacement response is more significant when the stiffness ratio of the face sheets to the core is large.The geometric nonlinearity decreases the shear stress and increases the normal stress in the sandwich core.By comparison with open literature and finite element simulations,the present nonlinear EHSAPT is shown to be sufficiently precise for estimating the nonlinear static response of sandwich beams by considering the geometric and material nonlinearities simultaneously. | Guangtao Wei Yang Jin Linzhi Wu | 2020 | Acta Mechanica Sinica2020，36，1： | 3 |

| 10 | MULTIPLE PARALLEL SYMMETRIC PERMEABLE MODEL-Ⅲ CRACKS IN A PIEZOELECTRIC/PIEZOMAGNETIC COMPOSITE MATERIAL PLANE显示文摘In this paper, the interactions of multiple parallel symmetric and permeable finite length cracks in a piezoelectric/piezomagnetic material plane subjected to anti-plane shear stress loading are studied by the Schmidt method.The problem is formulated through Fourier transform into dual integral equations, in which the unknown variables are the displacement jumps across the crack surfaces.To solve the dual integral equations, the displacement jumps across the crack surfaces are directly expanded as a series of Jacobi polynomials.Finally, the relation between the electric field, the magnetic flux field and the stress field near the crack tips is obtained.The results show that the stress, the electric displacement and the magnetic flux intensity factors at the crack tips depend on the length and spacing of the cracks.It is also revealed that the crack shielding effect presents in piezoelectric/piezomagnetic materials. | Zhengong Zhou Peiwei Zhang Linzhi Wu | 2010 | Acta Mechanica Solida Sinica2010，23，4： | 2 |
| 11 | The advanced development of molecular targeted therapy for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC),one of the most common malignant tumors in China,severely threatens the life and health of patients.In recent years,precision medicine,clinical diagnoses,treatments,and innovative research have led to important breakthroughs in HCC care.The discovery of new biomarkers and the promotion of liquid biopsy technologies have greatly facilitated the early diagnosis and treatment of HCC.Progress in targeted therapy and immunotherapy has provided more choices for precise HCC treatment.Multiomics technologies,such as genomics,transcriptomics,and metabolomics,have enabled deeper understanding of the occurrence and development mechanisms,heterogeneity,and genetic mutation characteristics of HCC.The continued promotion and accurate typing of HCC,accurate guidance of treatment,and accurate prognostication have provided more treatment opportunities and prolonged survival timelines for patients with HCC.Innovative HCC research providing an in-depth understanding of the biological characteristics of HCC will be translated into accurate clinical practices for the diagnosis and treatment of HCC. | Tao Yan Lingxiang Yu Ning Zhang Caiyun Peng Guodong Su Yi Jing Linzhi Zhang Tong Wu Jiamin Cheng Qian Guo Xiaoliang Shi Yinying Lu | 2022 | Cancer Biology & Medicine2022，19，6： | 2 |
| 12 | FREE VIBRATION ANALYSIS OF LATTICE SANDWICH BEAMS UNDER SEVERAL TYPICAL BOUNDARY CONDITIONS显示文摘Free vibration problems of lattice sandwich beams under several typical boundary conditions are investigated in the present paper.The lattice sandwich beam is transformed to an equivalent homogeneous three-layered sandwich beam.Unlike the traditional analytical model in which the rotation angles of the face sheets and the core are assumed the same,diferent rotation angles are considered in this paper to characterize the real response of sandwich beams.The analytical solutions of the natural frequencies for several typical boundary conditions are obtained.The efects of material properties and geometric parameters on the natural frequencies are also investigated. | Jia Lou Bing Wang Li Ma Linzhi Wu | 2013 | Acta Mechanica Solida Sinica2013，26，5： | 2 |
| 13 | Identification of Critical Hidden Failure Line Based on State-failure-network显示文摘The hidden failures generally exist in power systems and could give rise to cascading failures.Identification of hidden failures is challenging due to very low occurrence probabilities.This paper proposes a state-failure-network(SF-network)method to overcome the difficulty.The SF-network is formed by searching the failures and states guided by risk estimation indices,in which only the failures and states contributing to the blackout risks are searched and duplicated searches are avoided.Therefore,sufficient hidden failures can be obtained with acceptable computations.Based on the state and failure value calculations in the SF-network,the hidden failure critical component indices can be obtained to quantify the criticalities of the lines.The proposed SF-network method is superior to common sampling based methods in risk estimation accuracy.Besides,the state and failure value calculations in the SF-network used to re-estimate the risks after deployment of measures against hidden failures need shorter time in comparison with other risk re-estimation methods.The IEEE 14-bus and 118-bus systems are used to validate the method. | Linzhi Li Lu Liu Hao Wu Yonghua Song Dunwen Song Yi Liu | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，1： | 2 |
| 14 | Effect of temperature on the compressive behavior of carbon fiber composite pyramidal truss cores sandwich panels with reinforced frames显示文摘This paper focuses on the effect of temperature on the out-of-plane compressive properties and failure mechanism of carbon fiber/epoxy composite pyramidal truss cores sandwich panels(CF/CPTSP). CF/CPTSP with novel reinforced frames are manufactured by the water jet cutting and interlocking assembly method in this paper. The theoretical analysis is presented to predict the out-of-plane compressive stiffness and strength of CF/CPTSP at different ambient temperatures. The tests of composite sandwich panels are performed throughout the temperature range from -90℃ to 180℃. Good agreement is found between theoretical predictions and experimental measurements. Experimental results indicate that the low temperature increases the compressive stiffness and strength of CF/CPTSP. However, the high temperature causes the degradation of the compressive stiffness and strength. Meanwhile, the effects of temperature on the failure mode of composite sandwich panels are also observed. | Xiaodong Li Linzhi Wu Li Ma Xiangqiao Yan | 2016 | Theoretical & Applied Mechanics Letters2016，6，2： | 2 |
| 15 | A study on mechanical behavior of the carbon fiber composite sandwich panel with pyramidal truss cores at different temperatures显示文摘A series of compression tests were conducted to investigate the mechanical properties and failure mechanisms of carbon fiber composite sandwich panels using pyramidal truss cores subjected to temperatures ranging from 100℃ to 350℃.The compressive strength and stiffness of sandwich panels decreased as temperature increased.Cryogenic temperatures caused an increase in strength and stiffness,while elevated temperatures resulted in a reduction of strength and stiffness.The effect of temperature on the failure mode of the sandwich panel was revealed as well.The interface between the fiber and matrix was examined by a scanning electron microscope(SEM) in order to study the effect of temperature on strengthening the mechanism and good bonding conditions within the fiber-matrix interface was observed at cryogenic temperatures.The comparison of the predicted and experimental data indicated that the stiffness and strength of the composite sandwich panels for temperature variation was consistent. | LIU JiaYi ZHOU ZhenGong WU LinZhi MA Li | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，11： | 2 |
| 16 | The non-local theory solution of a Griffith crack in functionally graded materials subjected to the harmonic anti-plane shear waves显示文摘In this paper, the dynamic stress field near crack tips in the functionally graded materials subjected to the harmonic anti-plane shear stress waves was investi- gated by means of the non-local theory. The traditional concepts of the non-local theory were extended to solve the fracture problem of functionally graded materials. To make the analysis tractable, it was assumed that the material properties vary exponentially with coordinate parallel to the crack. By use of the Fourier transform, the problem can be solved with the help of a pair of dual integral equations, in which the unknown variable was the displacement on the crack surfaces. To solve the dual integral equations, the displacement on the crack surfaces was expanded in a series of Jacobi polynomials. Unlike the classical elasticity solutions, it is found that no stress singularities are present at crack tips. The non-local elastic solutions yield a finite hoop stress at crack tips, thus allowing us to use the maximum stress as a fracture criterion. The magnitude of the finite dynamic stress field depends on the crack length, the parameter describing the functionally graded materials, the circular frequency of the incident waves and the lattice parameter of materials. | ZHANG PeiWei ZHOU ZhenGong WU LinZhi | 2007 | Science China(Technological Sciences)2007，50，2： | 2 |

| 18 | Design of two dimensional nonsingular internal-external cloaks with arbitrary cross-section显示文摘According to the combination of the complementary medium and transformation optics, the shape of two-dimensional (2D) internal-external cloaks has been generalized into any geometry to adapt to the variety of object shapes. In order to adapt to the practical application, some approximations have been introduced to eliminate the infinite singularity of the parameters in the compressed region by adjusting the principle sketch out of the plane. Firstly, the general parameter equations of the nonsingular cloak with arbitrary cross-section are deduced strictly by the mathematical method based on coordinate transformations in the cylindrical coordinate system. Secondly, taking into account the discontinuous property of the curve functions of arbitrary polygons, a supplementary investigation is given for the nonsingular cloak with arbitrary polygonal cross-section. The transformations in the supplementary study are carried out in the Cartesian coordinate system directly and referred to the coordinates of the polygon's vertices rather than the curve function of the polygon. Last, the invisibility effect of the corresponding cloak is studied by full-wave simulations based on the finite element method. The applicable scope of the 2D internal-external cloak is expanded greatly by the methods and results given in this paper. | HE Xiao WU LinZhi | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，7： | 1 |
