| 1 | An Intra-Oceanic Subduction System Influenced by Ridge Subduction in the Diyanmiao Subduction Accretionary Complex of the Xar Moron Area,Eastern Margin of the Central Asian Orogenic Belt显示文摘This study focuses on the geology,geochemistry,Sr-Nd isotopes and their tectonic settings of three types of basalts in Diyanmiao ophiolite in the Xar Moron area located on the eastern margin of the Central Asian Orogenic Belt.Type I basalts are oceanic tholeiites with a depleted light rare earth element(LREE)pattern,which are similar to the typical N-mid-oceanic ridge basalt(MORB)and suggests that they were formed at a mid-oceanic ridge.The initial 87Sr/86Sr ratios of Type I basalts range from 0.703966 to 0.705276 and theεNd(t)values are from 16.49 to 17.15,indicating that they were derived from a depleted mantle source.Type II basalts belong to the medium-potassium calc-akaline series and have the geochem-ical characteristics of Nb-enriched basalt(NEB)with high Nb content(14.5 ppm)and strong enrichment in LREEs,implying that they were created by the partial melting of mantle wedge peridotite that previously metasomatized by slab melts.Type III basalts are high-Al basalt(HAB)with high-Al contents(Al_(2)0_(3)=16.75 wt.%-18.00 wt.%),distinct Nb depletion and high Th/Yb ratios.Thus they were likely gen-erated in a normal island-arc setting.Therefore,the association of MORB,NEB,and HAB in the study area may be due to the subduction of a mid-oceanic ridge,and the Diyanmiao ophiolite is proposed to be formed in the forearc setting of a mid-oceanic ridge subduction system. | Yang Cheng Qinghui Xiao Tingdong Li Liquan Xu Yuxu Fan Yan Li Lingjun Guo Jinli Pang Weiming Yuan | 2021 | Journal of Earth Science2021，32，1： | 6 |
| 2 | Microstructure and flexural properties of carbon/carbon composite with in-situ grown carbon nanotube as secondary reinforcement显示文摘Carbon nanotubes (CNTs) were in-situ grown in carbon felts using ferric chloride as catalyst and natural gas as carbon precursor via thermal gradient chemical vapor infiltration (TGCVI). Subsequently, the carbon felts were densified to obtain CNT reinforced carbon/carbon (C/C) composites in the same furnace. Effects of CNTs on the microstructure and flexural property of C/C composites were investigated by polarized light microscopy, Raman spectroscopy, scanning electron microscopy and universal mechanical testing machine. The results of PLM observation and Raman analysis showed that CNTs have two-sided effects on the microstructure of pyrocarbon: the pyrocarbons in the region without CNTs show medium texture; while, in the region full of CNTs, the microstructure was low-textured or even isotropic though the TGCVD conditions would lead to the deposition of pure low texture pyrocarbons. Analysis based on stress-strain curves demonstrated that the flexural strength increased first and then decreased with the CNT content increasing. When the CNT content was 5.23 wt%, the flexural strength was maximum and had a nearly 35% improvement compared with pure C/C composite. Besides, after adding CNTs, the flexural modulus of the composites decreased and the ductility increased obviously, indicating CNTs can toughen C/C composites. | Hai Zhang Lingjun Guo Qiang Song Qiangang Fu Hejun Li Kezhi Li | 2013 | Progress in Natural Science:Materials International2013，23，2： | 6 |
| 3 | Effect of chemical vapor infiltration treatment on the wave-absorbing performance of carbon fiber/cement composites显示文摘Short carbon fibers were treated at high temperatures around 1100°C through chemical vapor infiltration technology. A thinner layer of pyrocarbon was deposited on the fiber surface. The dispersion of carbon fibers in a cement matrix and the mechanical properties of carbon fiber/cement composites were investigated by scanning electron microscopy (SEM) and other tests. The reflec-tivity of electromagnetic waves by the composites was measured in the frequency range of 8.0-18 GHz for different carbon fiber contents of 0.2wt%, 0.4wt%, 0.6wt%, and 1.0wt%. The results show that the reflectivity tends to increase with the increase of fiber content above 0.4wt%. The minimum reflectivity is -19.3 dB and the composites exhibit wave-absorbing performances. After pyro-carbon is deposited on the fiber, all the reflectivity data are far greater. They are all above -10 dB and display mainly wave-reflecting performances. | Kezhi Li Chuang Wang Hejun Li Lingjun Guo Jihua Lu | 2008 | Journal of University of Science and Technology Beijing2008，15，6： | 4 |

| 8 | Geochemistry and Tectonic History of Seamount Remnants in the Xingshuwa Subduction Accretionary Complex of the Xar Moron Area,Eastern Margin of the Central Asian Orogenic Belt显示文摘This study focuses on the geology,geochemistry,zircon U-Pb geochronology and tectonic settings of the three types of seamount basalts from the Xingshuwa subduction accretionary complex in the Xar Moron area,eastern margin of the Central Asian Orogenic Belt(CAOB).The seamount remnants are composed of carbonate’cap’sediments,large volumes of pillow and massive basalts,carbonate breccia slope facies and radiolarian cherts.Group 1 basalts are characterized by high contents of P2 O5 and TiO2 with alkaline affinity and LREE enrichment,indicating that they are derived from intraplate magma.Group 2 basalts display N-MORB LREE depletion patterns,indicating that they were formed at a mid-ocean ridge.Group 3 basalts have shown distinct Nb depletion and high Th/Yb ratios,indicating that they were generated in an island arc tectonic setting.The zircon U-Pb age of Group 1 basalt sample XWT18-131 is 576.4±9.4 Ma,suggesting that the oceanic island seamount was the product of intraplate magmatism related to a mantle plume or’hot spot’in the late Neoproterozoic.The zircon U-Pb age of Group 2 basalt sample XWT18-132 is 483±22 Ma,indicating that the Paleo-Asian Ocean(PAO)was continuously expanding in the Early Ordovician.The zircon U-Pb age of Group 3 basalt sample XWT18-101 is 240.5±8.2 Ma,suggesting that this area underwent the evolutionary path of ocean-continent transition,developing towards continentalization during the Middle Triassic.Thus,we believe that there was both mantle plume-related intraplate magmatism and intraoceanic subduction during the evolution of the PAO,the CAOB possibly being an evolutionary model of an intraoceanic subduction and mantle plume magmatism complex. | CHENG Yang XIAO Qinghui LI Tingdong LI Yan FAN Yuxu XU Liquan GUO Lingjun PANG Jinli | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 1 |
| 9 | Atmospheric sulfur hexafluoride in-situ measurements at the Shangdianzi regional background station in China显示文摘We present in-situ measurements of atmospheric sulfur hexafluoride(SF6)conducted by an automated gas chromatograph–electron capture detector system and a gas chromatography/mass spectrometry system at a regional background site,Shangdianzi,in China,from June 2009 to May 2011,using the System for Observation of Greenhouse gases in Europe and Asia and Advanced Global Atmospheric Gases Experiment(AGAGE)techniques.The mean background and polluted mixing ratios for SF6during the study period were 7.22×10-12(mol/mol,hereinafter)and 8.66×10-12,respectively.The averaged SF6background mixing ratios at Shangdianzi were consistent with those obtained at other AGAGE stations located at similar latitudes(Trinidad Head and Mace Head),but larger than AGAGE stations in the Southern Hemisphere(Cape Grim and Cape Matatula).SF6background mixing ratios increased rapidly during our study period,with a positive growth rate at 0.30×10-12year-1.The peak to peak amplitude of the seasonal cycle for SF6background conditions was 0.07×10-12,while the seasonal fluctuation of polluted conditions was 2.16×10-12.During the study period,peak values of SF6mixing ratios occurred in autumn when local surface horizontal winds originated from W/WSW/SW/SWS/S sectors,while lower levels of SF6mixing ratios appeared as winds originated from N/NNE/NE/ENE/E sectors. | Bo Yao Lingxi Zhou Lingjun Xia Gen Zhang Lifeng Guo Zhao Liu Shuangxi Fang | 2014 | Journal of Environmental Sciences2014，26，12： | 0 |

| 11 | 评估帕博利珠单抗在中国晚期黑色素瘤患者中的应用:基于KEYNOTE-151研究的3年随访数据显示文摘中国肢端和黏膜黑色素瘤的发病率较高,但治疗选择有限,晚期黑色素瘤患者的生存率普遍较低。对Ib期KEYNOTE-151研究的初步分析显示,帕博利珠单抗在作为二线药物治疗中国晚期黑色素瘤患者中,表现出了良好的耐受性和优异的临床抗肿瘤活性。本研究分析了3年随访的研究数据,纳入一线治疗后进展的不可切除的III/IV期中国黑色素瘤患者,给予帕博利珠单抗2 mg/kg治疗,每3周1次,最长使用35剂。主要终点为安全性和客观缓解率(objective response rate,ORR);次要终点包括疗效维持时间(duration of response,DOR)、无进展生存期(progression-free survival,PFS)和总生存期(overall survival,OS)。根据RECIST v1.1标准,采用独立中心盲法评估患者疗效。此外,根据黑色素瘤亚型,以及BRAF突变状态和PD-L1表达状态(仅肢端黑色素瘤)进行亚组分析。本研究共纳入103例患者,中位随访时间[从首次用药到数据截止时间(2020年7月13日)]为44.6个月[四分位距(interquartile range,IQR):39.1–46.2]。85.4%的患者发生了任一级别的治疗相关不良事件(treatment-related adverse events,TRAEs),12.6%的患者发生了3/4级的TRAEs,无5级TRAE发生。3例患者因TRAEs(免疫相关肝炎、肺炎和关节炎)停药。免疫相关AEs和输液反应发生比例为34.0%(3/4级,2.9%)。ORR为17.6%(95%CI:10.8–26.4;1例完全缓解/17例部分缓解),中位DOR为13.8个月(范围:2.7–37.4+)。中位PFS为2.8个月(95%CI:2.7–3.5),36个月的PFS率为5.0%。中位OS为13.2个月(95%CI:10.4–16.5),36个月的OS率为22.3%。肢端黑色素瘤中位OS为14.8个月,非肢端皮肤黑色素瘤为13.5个月,黏膜黑色素瘤为7.4个月。在肢端黑色素瘤亚组中,程序性死亡配体-1(programmed death ligand-1,PD-L1)阳性的中位OS为22.8个月,PD-L1阴性的中位OS为8.4个月,BRAF野生型的中位OS为18.5个月,BRAF突变型的中位OS为5.8个月。综上,本研究对3年随访数据分析结果表明,帕博利珠单抗作为二线治疗在中国晚期黑色素瘤患者中的安全性可控,且达到了具有临床意义的抗肿瘤活性,使部分患者获得持久缓解。亚组分析表明PD-L1阳性和BRAF野生型的肢端黑色素瘤患者从该治疗中获益较大,但由于亚组样本量较小,该研究结论仍需进一步验证。 | Lu Si Xiaoshi Zhang Yongqian Shu Hongming Pan Di Wu Jiwei Liu Lili Mao Xuan Wang Xizhi Wen Yanhong Gu Lingjun Zhu Shijie Lan Xin Cai Scott J.Diede Haiyan Dai Cuizhen Niu Jianfeng Li Jun Guo 李雯钰(翻译校对) 斯璐(点评) | 2023 | 癌症2023，42，8： | 0 |
| 12 | A new multi-source remote sensing image sample dataset with high resolution for flood area extraction:GF-FloodNet显示文摘Deep learning algorithms show good prospects for remote sensingflood monitoring.They mostly rely on huge amounts of labeled data.However,there is a lack of available labeled data in actual needs.In this paper,we propose a high-resolution multi-source remote sensing dataset forflood area extraction:GF-FloodNet.GF-FloodNet contains 13388 samples from Gaofen-3(GF-3)and Gaofen-2(GF-2)images.We use a multi-level sample selection and interactive annotation strategy based on active learning to construct it.Compare with otherflood-related datasets,GF-FloodNet not only has a spatial resolution of up to 1.5 m and provides pixel-level labels,but also consists of multi-source remote sensing data.We thoroughly validate and evaluate the dataset using several deep learning models,including quantitative analysis,qualitative analysis,and validation on large-scale remote sensing data in real scenes.Experimental results reveal that GF-FloodNet has significant advantages by multi-source data.It can support different deep learning models for training to extractflood areas.There should be a potential optimal boundary for model training in any deep learning dataset.The boundary seems close to 4824 samples in GF-FloodNet.We provide GF-FloodNet at http://gffzz32f81fe4765d4826sbn5o6bwuwu666vxn.ffgz.tsg.suse.edu.cn/datasets/pengliuair/gf-floodnet and http://gffzzfe5ad979a04a470asbn5o6bwuwu666vxn.ffgz.tsg.suse.edu.cn/s/1vdUCGNAfFwG5UjZ9RLLFMQ?pwd=8v6o. | Yuwei Zhang Peng Liu Lajiao Chen Mengzhen Xu Xingyan Guo Lingjun Zhao | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 13 | Micro-and Nano-structure Characterization of Isotropic Pyrocarbon Obtained via Chemical Vapor Deposition in Hot Wall Reactor显示文摘The hot wall reactor was used to deposit isotropic pyrocarbon.The density of the product was measured by Archimedes method.The fracture morphology and texture of the product were investigated by scanning electron microscopy(SEM) and transmission electron microscopy(TEM).Raman spectroscopy was also applied to characterizing the structure of the product.The results show that the density of the product is about 1.31 g/cm3.The pyrocarbon consists of granular particles with the size of about 1.5 μm under SEM images.Under TEM images,the pyrocarbon is composed of irregular grains and onion-like particles are also detected.The orientation angle(180 deg.) of pyrocarbon reveals its isotropic character.The ID/IG ratio in Raman spectrum is about 1.2,indicating the isotropic feature of the product qualitatively. | Kezhi Li,Dongsheng Zhang,Lingjun Guo and Hejun Li State Key Laboratory of Solidification Processing,Northwestern Polytechnical University,Xi an 710072,China | 2010 | Journal of Materials Science & Technology2010，26，12： | 0 |
| 14 | X-ray Diffraction and Raman Spectroscopy Characterization of Isotropic Pyrocarbon Obtained by Hot Wall Chemical Vapor Deposition显示文摘Varying the flow rate of natural gas from 50 to 80 to 120 l/h, isotropic pyrocarbon produced by hot wall chemical vapor deposition at 1000 ℃ were examined by X-ray diffraction and Raman spectroscopy. The X-ray data were evaluated by Scherrer equation, and the intensity ratio of D to G band derived from Raman data was used to evaluate the lateral extension of isotropic pyrocarbon. The experimental results show that the d002-spacing of isotropic pyrocarbon decreases from 0.3499 nm to 0.3451 nm, while the stack height increases from 6.5 to 8.4 nm with the increase of flow rate of natural gas. The intensity ratio of D to G band and lateral extension of isotropic pyrocarbon increases with natural gas flow rate increasing. After heat treatment, all the crystallite parameters (stack height, lateral extension, and d002-spacing) decrease, indicating the improvement of the arrangement of the basic structural units of isotropic pyrocarbon. | 张东生 LI kezhi JIA Yan GUO Lingjun LI Hejun LU Jinhua | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，2： | 0 |
| 15 | Effects of Carbon Nanotubes by Electrophoretic Deposition on Interlaminar Properties of Two Dimensional Carbon/carbon Composites显示文摘Carbon nanotubes(CNTs) were deposited uniformly on carbon cloth by electrophoretic deposition(EPD). Thereafter, CNT-doped clothes were stacked and densified by pyrocarbon via chemical vapor infiltration to fabricate two-dimensional(2 D) carbon/carbon(C/C) composites. Effects of EPD CNTs on interlaminar shear performance and mode Ⅱ interlaminar fracture toughness(GⅡc) of 2 D C/C composites were investigated. Results showed that EPD CNTs were uniformly covered on carbon fibers, acting as a porous coating. Such a CNT coating can obviously enhance the interlaminar shear strength and GⅡc of 2 D C/C composites. With increaing EPD CNTs, the interlaminar shear strength and GⅡc of 2 D C/C composites increase greatly and then decrease, both of which run up to their maximum values, i e, 13.6 MPa and 436.0 J·m-2, when the content of EPD CNTs is 0.54 wt%, 2.27 and 1.45 times of the baseline. Such improvements in interlaminar performance of 2 D C/C composites are mainly beneficial from their increased cohesion of interlaminar matrix, which is caused not only by the direct reinforcing effect of EPD CNT network but also by the capacity of EPD CNTs to refine pyrocarbon matrix and induce multilayered microstructures that greatly increase the crack propagation resistance through 'crack-blocking and-deflecting mechanisms'. | 黎云玉 GUO Lingjun LI Hejun MA Haili 宋强 | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，5： | 0 |
| 16 | Spontaneous emission rate and optical amplification of Er3+ in double slot waveguide显示文摘The spontaneous emission(SE) of Er3+ embedded in a double slot dielectric structure was studied by a quantum-electrodynamical formalism. The study shows that the slot width and the position of Er3+ in slot structure have a significant effect on the SE. The double slot waveguides were fabricated by embedding two low-index Er/Yb silicate material layers into high-index silicon. The radiative efficiency of Er3+ in the double slot waveguides is found to be higher than that of the single slot waveguide, which is consistent with the theory simulation. The 0.67 d B signal enhancement at 1.53 ?m in a 4.6-mm-long slot waveguide was observed pumped by 1476 nm laser. These results show the relevance of our model to study the SE processes in multilayer structures and are important for future realization of silicon-compatible active optical devices. | WANG XingJun JIANG LingJun GUO RuiMin YE Rui ZHOU ZhiPing | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，12： | 0 |
