| 3 | Effects of Laser Shock Processing on Mechanical Properties of Laser Welded ANSI 304 Stainless Steel Joint显示文摘With the rapid development of engineering component with integration,high-speed and multi-parameter,traditional techniques haven't met practical needs in extreme service environment.Laser welding,a new welding technology,has been widely used.However,it would generate the drop of mechanical properties for laser welded joint due to its thermal effect.Laser shock processing(LSP) is one of the most effective methods to improve the mechanical properties of laser welded ANSI 304 stainless steel joint.In this paper,the effects of LSP on the mechanical properties of laser welded ANSI 304 stainless steel joint have been investigated.The welded joint on the front of the tensile samples is treated by LSP impacts,and the overlapping rate of the laser spot is 50%.The tensile test of the laser welded joint with and without LSP impacts is carried out,and the fracture morphology of the tensile samples is analyzed by scanning electron microscope(SEM).Compared with the yield strength of 11.70 kN,the tensile strength of 37.66 kN,the yield-to-tensile strength ratio of 0.310 7,the elongation of 25.20%,the area reduction of 32.68% and the elastic modulus of 13 063.876 MPa,the corresponding values after LSP impacts are 14.25 kN,38.74 kN,0.367 8,26.58%,42.29% and 14 754.394 MPa,respectively.Through LSP impacts,the increasing ratio of the yield strength and tensile strength are 121.79% and 102.87%,respectively;the elongation and area reduction are improved by 5.48% and 29.38%,respectively.By comparing with coarse fracture surface of the welded joint,the delamination splitting with some cracks in the sharp corner of the welded joint and asymmetric dimples,LSP can cause brighter fracture surface,and finer and more uniform dimples.Finally,the schematic illustration of dimple formation with LSP is clearly described.The proposed research ensures that the LSP technology can clearly improve the yield strength,tensile strength,yield-to-tensile strength ratio,elongation,area reduction and elastic modulus of the welded joint.The enhancement mechanism of LSP on laser welded ANSI 304 stainless steel joint is mainly due to the fact that the refined and uniform dimples effectively delay the fracture of laser welded joints. | ZHANG Yongkang ZHANG Lei LUO Kaiyu SUN Guifang LU Jinzhong DAI Fengze ZHONG Junwei | 2012 | Chinese Journal of Mechanical Engineering2012,25,2: | 11 |
| 4 | Ground Surface Ruptures and Near-Fault,Large-Scale Displacements Caused by the Wenchuan Ms8.0 Earthquake Derived from Pixel Offset Tracking on Synthetic Aperture Radar Images显示文摘The 12 May 2008 Wenchuan Ms8.0 earthquake produced surface displacements along the causative fault,the Yingxiu-Beichuan Fault,which are up to several meters near the fault.Because of the large gradient,satellite synthetic aperture radar(SAR) interferometric data are strongly incoherent;the usual SAR interferometry method does not allow such displacements to be measured.In the present study,we employed another approach,the technique based on pixel offset tracking,to solve this problem.The used image data of six tracks are from the Advanced Land Observing Satellite,Phased Array type L-band Synthetic Aperture Radar(ALOS/PALSAR) dataset of Japan.The results show that the entire surface rupture belt is 238 km long,extending almost linearly in a direction of 42° north-east.It is offset left laterally by a north-west-striking fault at Xiaoyudong,and turns at Gaochuan,where the rupture belt shifts toward the south by 5 km,largely keeping the original trend.In terms of the features of the rupture traces,the rupture belt can be divided into five sections and three types.Among them,the Beichuan-Chaping and Hongkou-Yingxiu sections are relatively complex,with large widths and variable traces along the trend.The Pingtong-Nanba and Qingping-Jingtang sections appear uniform,characterized by straight traces and small widths.West of Yingxiu,the rupture traces are not clear.North of the rupture belt,surface displacements are 2.95 m on average,mostly 2-3.5 m,with 7-9 m the maximum near Beichuan.South of the rupture belt,the average displacement is 1.75 m,dominated by 1-2 m,with 3-4 m at a few sites.In the north,the displacements in the radar line of sight are of subsidence,and in the south,they are uplifted,in accordance with a right-slip motion that moves the northern wall of the fault to the east,and the southern wall to the west,respectively.Along the Guanxian-Jiangyou Fault,there is a uplift zone in the radar line of sight,which is 66 km long,1.5-6 km wide,and has vertical displacements of approximately 2 m,but no observable rupture traces. | QU Chunyan SHAN Xinjian LIU Yunhua ZHANG Guohong SONG Xiaogang ZHANG Guifang GUO Liming HAN Yufei | 2012 | Acta Geologica Sinica(English Edition)2012,86,2: | 10 |

| 6 | Reversible RNA Modification N^1-methyladenosine(m^1A) in mRNA and tRNA显示文摘More than 100 modifications have been found in RNA. Analogous to epigenetic DNA methylation, epitranscriptomic modifications can be written, read, and erased by a complex network of proteins. Apart from N^6-methyladenosine(m^6A), N^1-methyladenosine(m^1A) has been found as a reversible modification in tRNA and mRNA. m^1A occurs at positions 9, 14, and 58 of tRNA, with m^1A58 being critical for t RNA stability. Other than the hundreds of m^1A sites in mRNA and long non-coding RNA transcripts, transcriptome-wide mapping of m^1A also identifies>20 m^1A sites in mitochondrial genes. m^1A in the coding region of mitochondrial transcripts can inhibit the translation of the corresponding proteins. In this review, we summarize the current understanding of m^1A in mRNA and tRNA, covering high-throughput sequencing methods developed for m^1A methylome, m^1A-related enzymes(writers and erasers), as well as its functions in mRNA and tRNA. | Chi Zhang Guifang Jia | 2018 | Genomics, Proteomics & Bioinformatics2018,16,3: | 8 |

| 8 | Stem cell lineage in body layer specialization and vascular patterning of rice root and leaf显示文摘Since the first appearance of vascular plants during evolution, the plant body has become specialized for adaption to land conditions. Much of our knowledge of plant body specialization and the origins of tissues from stem cells have been obtained from studies on the dicot Arabidopsis thaliana. However, less is known about plant body specialization in monocots, another important branch of angiosperms. In this study, we analyzed stem cell lineage and differentiation during development of the root and leaf of the monocot model plant rice(Oryza sativa). Our results showed that three body layers of rice are established from stem cells accompanied by progressively reduced pluripotency. Layer 1(L1) is a single-cell layer of epidermis; L2 is the cortex/endodermis in the root and the mesophyll in the leaf; and L3 is the site of vascular initiation. At least two common steps in vascular development are shared between rice root and leaf. The preprocambium divides to form the procambium and root pericycle or leaf outer sheath. The procambium further differentiates into the xylem, phloem and circumambient cells. We found that the outer sheath of leaf vascular bundles originates not only from the preprocambium of L3,but also from the mesophyll precursor cells of L2. In addition, WUSCHEL-RELATED HOMEOBOX(WOX)genes are expressed in not only the stem cell niche but also metaxylem precursor in rice. This pattern differs from that of homologs in Arabidopsis, suggesting that WOX functions have been recruited in different stem cells in dicots and monocots. | Minhuan Zeng Bo Hu Jiqin Li Guifang Zhang Ying Ruan Hai Huang Hua Wang Lin Xu | 2016 | Science Bulletin2016,61,11: | 5 |
| 9 | Expression of human soluble TRAIL in Chlamydomonas reinhardtii chloroplast显示文摘Tumor necrosis factor-related apop-tosis-inducing ligand (TRAIL) induces selectively apoptosis in various tumor cells and virus-infected cells, but rarely in normal cells. A chloroplast expres-sion vector, p64TRAIL, containing the cDNA coding for the soluble TRAIL (sTRAIL), was constructed with clpP-trnL-petB-chlL-rpl23-rpl2 as Chlamydomonas reinhardtii plastid homologous recombinant frag-ments and spectinomycin-resistant aadA gene as a select marker. The plasmid p64TRAIL was trans-ferred into the chloroplast genome of C. reinhardtii by the biolistic method. Three independently trans-formed lines were obtained by 100 mg/L spectino-mycin selection. PCR amplification, Southern blot analysis of the sTRAIL coding region DNA and culti-vation cells in the dark all showed that the exogenous DNA had been integrated into chloroplast genome of C. reinhardtii. Western blot analysis showed that human soluble TRAIL was expressed in C. reinhardtii chloroplast. The densitometric analysis of Western blot indicated that the expressed human sTRAIL protein in the chloroplasts of C. reinhardtii accounted for about 0.43%―0.67% of the total soluble proteins. These experimental results demonstrated the possi-bility of using transgenic chloroplasts of green alga as bioreactors for production of biopharmaceuticals. | YANG Zongqi LI yinü CHEN Feng LI Dong ZHANG Zhifang LIU Yanxin ZHENG Dexian WANG Yong SHEN Guifang | 2006 | Chinese Science Bulletin2006,51,14: | 4 |
| 10 | Gastrodin blocks neural stem cell differentiation into glial cells mediated by kainic acid显示文摘Kainic acid can simulate excitatory amino acids in vitro.Neural stem cells,isolated from newborn Wistar rats,were cultured in vitro and exposed to 100-4 000 μM kainic acid for 7 days to induce neuronal cell differentiation,causing the number of astrocytes to be significantly increased.Treatment with a combination of 0.5 mg/L gastrodin and kainic acid also caused the number of differentiated neurons to be significantly increased compared with treatment with kainic acid alone.Experimental findings suggest that gastrodin reduces the excitability of kainic acid and induces neural stem cell differentiation into neurons. | Guifang Sun Zhihao Yuan Boai Zhang Yanjie Jia Yangfei Ji Xingrong Ma Yu Liu Yanru Liu Quanqing Wen Yanling Zhao | 2012 | Neural Regeneration Research2012,7,12: | 4 |
| 11 | The Crustal Structure and Seismic Activity in North China显示文摘A layered crustal block model of North China has been constructed based on large amount of data from seismic sounding carried out in recent two decades. Some deep fault zones, such as the Zhangjiakou.Penglai and Tancheng-Lujiang fault zones, divide the upper crust of North China into three upper crustal terranes and nine bolcks. There are distinct differences in velocity and depth distributions, which reflects Cenozoic block faulting in North China in the process of formation of the deep structure. The upper crust shows the features of transition in isostatic adjustment. The existence of a low-velocity layer in the middle crust is characteristic of the crustal structure in North China. There seems to be an increase of rheology of the rocks in the lower crust and a persistence of stable regional stress field. The patterns of the Moho on two sides of the Yanshan-Taihang Mountains are different. The relief of the Moho around Beijing, Shijiazhuang and Guangrao where the deep faults join together shows a quadrantal distribution in some degree. The dynamic sources for seismic activity are the NE-SW horizontal compression and the diapirism of the upper mantle. The middle and upper crust, especially the layered block structure has the most significant effects on seismicity, and the occurrence of earthquakes is more closely related to them than to the Moho. | Feng Rui Institute of Geophysics, State Seismological Bureau, Beijing Huang Guifang, Zheng Shuzhen, Wang Jun, Yan Huifen Geophysical Prospecting Party, State Seismological Bureau, Zhengzhou, Henan and Zhang Ruoshui Seismological Technique College, State Seismological Bureau, Yanjiao,Hebei | 1989 | Acta Geologica Sinica(English Edition)1989,63,4: | 4 |

| 14 | Ultra-flat dispersion in an integrated waveguide with five and six zero-dispersion wavelengths for mid-infrared photonics显示文摘We propose a new type of dispersion flattening technology, which can generate an ultra-flat group velocity dispersion profile with five and six zero-dispersion wavelengths(ZDWs). The dispersion value varies from-0.15 to 0.35 ps/(nm·km) from 4 to 8 μm, which to the best of our knowledge is the flattest one reported so far, and the dispersion flatness is improved by more than an order of magnitude. We explain the principle of producing six ZDWs. Mode distribution in this waveguide is made stable over a wide bandwidth. General guidelines to systematically control the dispersion value, sign, and slope are provided, and one can achieve the desired dispersion by properly adjusting the structural parameters. Fabrication tolerance of this waveguide is also examined. | Yuhao Guo Zeinab Jafari Lijuan Xu Changjing Bao Peicheng Liao Guifang Li Anuradha M.Agarwal Lionel C.Kimerling Jurgen Michel Alan E.Willner Lin Zhang | 2019 | Photonics Research2019,7,11: | 3 |
| 15 | High flux photocatalytic self-cleaning nanosheet C_(3)N_(4) membrane supported by cellulose nanofibers for dye wastewater purification显示文摘Hazardous dye substances discharged from the textile and dyestuff industries not only threaten local the surrounding ecosystems but are also hard to degraded.We report the preparation of process for a photocatalytic membrane device that can degrade dye pollution under visible light.This filtration membrane,with a well-organized multilayer structure,simultaneously achieves continuous and flow-through separation of degradation products.Cellulose nanofibers(CNFs)were used as a template for nanosheet C_(3)N_(4)(NS C_(3)N_(4))preparation;the performance for the photocatalytic degradation of dyes improved as the morphology changed from bulking to nanosheet.NS C3N4 was then attached to the surface of a prepared CNF membrane via vacuum filtration.This device exhibited high efficiency(the degradation rates of both Rhodamine B and Methylene blue both reached 96%),high flux(above 160 L·h^(-1)·m^(-2)·bar^(-1))and excellent stability(maintaining steady flux and high separation were maintained after 4 h).This easy-preparation,easy-scale-up,and low-cost process provides a new method of fabricating photocatalytic membrane devices for dye wastewater treatment. | Lilong Zhang Ge Meng Guifang Fan Keli Chen Yulong Wu Jian Liu | 2021 | Nano Research2021,14,8: | 3 |
| 16 | Earthquake deformation field characteristics associated with the 2010 Yushu M_s7.1 earthquake显示文摘The spatial distribution and characterization of a heavily damaged area can be determined by studying surface ruptures of seismogenic faults.If the distribution of surface ruptures can be obtained shortly after they occur,then areas heavily damaged by an earthquake can be readily identified.The information can then be used as a guide for earthquake relief programs.In this paper,an intensity offset-tracking method applied to an ALOS PALSAR image is used to map the Yushu earthquake rupture and to identify the faults activated by the earthquake.Azimuthal displacement analysis indicates that the surface rupture is about 55 km long,running from the epicenter to the southeast,trending N310°W,with a relative displacement of~1 m characterized by sinistral slip.The result of range displacement observations indicates that the north wall of the fault is dominated by decreases(i.e.,uplift in line of sight observations) ,whereas in the south wall of the fault,the range displacement is dominated by increases(drops in line of sight observations) .Given the position from which the images were recorded,this means that the north wall moves westward,and the south wall move eastward,i.e.,left-lateral slip motion across the fault.Finally,an earthquake disaster assessment using computer-assisted image analysis software shows that buildings near the fault rupture have been destroyed most heavily;therefore,the shape of the heavily damage belt is controlled partially by the fault rupture's geometry and the damage degree relates to the magnitude of displacement field. | LIU YunHua SHAN XinJian QU ChunYan ZHANG GuiFang | 2011 | Science China Earth Sciences2011,54,4: | 3 |
