| 1 | Effects of B on the Microstructure and Oxidation Resistance of Nb-Ti-Si-based Ultrahigh-temperature Alloy显示文摘采用电弧熔炼法制备了B含量为0到2at.%的Nb-Ti-Si基超高温合金。分析了B对Nb-Ti-Si基超高温合金的电弧熔炼态组织及氧化行为的影响。电弧熔炼态Nb-22Ti-16Si-6Cr-3Al-4Hf合金由(Nb,Ti)ss,β-(Nb,Ti)5Si3和γ-(Nb,Ti)5Si3组成,而Nb-22Ti-16Si-6Cr-3Al-4Hf-1B和Nb-22Ti-16Si-6Cr-3Al-4Hf-2B合金则由(Nb,Ti)ss,α-(Nb,Ti)5Si3和γ-(Nb,Ti)5Si3组成。Nb-Ti-Si基超高温合金主要是通过界面和(Nb,Ti)ss发生氧化的,在添加B的合金中,B明显降低了其在1200℃前50小时的氧化速率,但50小时后,B的添加反而降低了合金的抗氧化性。 | Wang Jun Guo Xiping Guo Jinming | 2009 | Chinese Journal of Aeronautics2009，22，5： | 8 |
| 2 | Grapevine VlbZIP30 improves drought resistance by directly activating VvNAC17 and promoting lignin biosynthesis through the regulation of three peroxidase genes显示文摘Drought stress severely affects grapevine quality and yield,and recent reports have revealed that lignin plays an important role in protection from drought stress.Since little is known about lignin-mediated drought resistance in grapevine,we investigated its significance.Herein,we show that VlbZIP30 mediates drought resistance by activating the expression of lignin biosynthetic genes and increasing lignin deposition.Transgenic grapevine plants overexpressing VlbZIP30 exhibited lignin deposition(mainly G and S monomers)in the stem secondary xylem under control conditions,which resulted from the upregulated expression of VvPRX4 and VvPRX72.Overexpression of VlbZIP30 improves drought tolerance,characterized by a reduction in the water loss rate,maintenance of an effective photosynthesis rate,and increased lignin content(mainly G monomer)in leaves under drought conditions.Electrophoretic mobility shift assay,luciferase reporter assays,and chromatin immunoprecipitation-qPCR assays indicated that VlbZIP30 directly binds to the G-box cis-element in the promoters of lignin biosynthetic(VvPRX N1)and drought-responsive(VvNAC17)genes to regulate their expression.In summary,we report a novel VlbZIP30-mediated mechanism linking lignification and drought tolerance in grapevine.The results of this study may be of value for the development of molecular breeding strategies to produce drought-resistant fruit crops. | Mingxing Tu Xianhang Wang Wuchen Yin Ya Wang Yajuan Li Guofeng Zhang Zhi Li Junyang Song Xiping Wang | 2020 | Horticulture Research2020，7，1： | 5 |
| 3 | Coarsening behavior of γ' particles in a nickel-base superalloy显示文摘The coarsening behavior of γ' particles in a nickel-base superalloy FGH95 was investigated by means of experimental observations and growth kinetics calculations. The results show that when aging at 1000,1080 and 1140°C for different times,the relation of average particle size to time obeys the cube law ( a /2)3= kt,where k is 15.49 × 103,77.5 × 103 and 230.04 × 103 nm3/min,respectively. The particle size distributions are better fit to the LSW theoretical distributions when aging at 1000°C within 1440 min. The activation energy for γ' particles coarsening is determined to be 288.20±1.79 kJ/mol,which correlates well to the diffusion activation energies of Al,Ti,and Nb in the nickel matrix. This indicates that the coarsening of γ' particles is controlled by the diffusion of Al,Ti,and Nb in the nickel matrix. The coarsening kinetics of γ' particles in FGH95 is predicted as rt 3 = 1.04 × 10 16t exp[-(288200 ± 1790 )/RT]. | Li, Hongyu Zuo, Lingli Song, Xiping Wang, Yanli Chen, Guoliang | 2009 | Rare Metals2009，28，2： | 5 |

| 5 | Characterization of γ′ precipitates in a nickel base superalloy quenching from aging temperature at different rates显示文摘The characteristics of γ′ precipitates in a superalloy quenched from 1050°C at different rates were investigated using field emission scanning electron microscope(FESEM).When quenched from 1050°C, the size of primary aging γ′ precipitates has a small increase in the specimens that experienced iced-brine-quenching, oil-quenching, and air-cooling-quenching conditions and a drastic increase in the specimen that experienced a furnace-cooling-quenching condition.The cooling γ′ precipitates have unimodal distributions after quenching at the air-cooling rate and bimodal distributions after quenching at the furnace-cooling rate, but there are not these distributions in the specimens that experienced iced-brine-quenching and oil-quenching conditions.When aging at 760°C, the size of primary aging γ′ precipitates appears unaffected in the specimens that experienced iced-brine-quenching, oil-quenching, and air-cooling-quenching conditions.However, it has a drastic increase in the specimen that experienced a furnace-cooling-quenching condition, and it is interesting that the bigger cooling γ′ precipitates have a coalescence and octodendritic shape.The microhardness study indicates that the hardness has no variation in the specimens that experienced iced-brine-quenching, oil-quenching, and air-cooling-quenching conditions and has a drastic decrease in the specimens that experienced a furnace-cooling-quenching condition and obtains the minimum microhardness value 390.8 HV. | LI Hongyu, SONG Xiping, WANG Yanli, and CHEN Guoliang State Key Lab for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China | 2010 | Rare Metals2010，29，2： | 4 |
| 6 | Effect of rapid quenching on the microstructure and electrochemical characteristics of La_(0.6)Ce_(0.4)Ni_(3.6)Co_(0.65)Mn_(0.4)Al_(0.2)Ti_(0.05_(FeB)_(0.1) hydrogen storage alloy显示文摘In order to improve the cycling stability of AB5 type alloy electrodes,rapid quenching technology and new alloy composition design were employed.A hydrogen storage alloy with nominal composition La0.6Ce0.4Ni3.6Co0.65Mn0.4Al0.2Ti0.05(FeB)0.1 was prepared by vacuum magnetic levitation melting under high purity argon atmosphere,followed by rapid quenching at different cooling rates.XRD results show that all alloys exhibit the single-phase CaCu5-type structure.Electrochemical tests indicate that rapid quenching can slightly improve the cycling life of the alloy.Nevertheless,the high-rate dischargeability of the quenched alloys is lower than that of the as-cast alloy. | ZHANG Peilong SONG Xiping WANG Xiuli PEI Pei LUO Guiping TU Jiangping CHEN Guoliang | 2010 | Rare Metals2010，29，6： | 4 |
| 7 | NOMA-Based Energy-Efficient Task Scheduling in Vehicular Edge Computing Networks: A Self-Imitation Learning-Based Approach显示文摘Mobile Edge Computing(MEC)is promising to alleviate the computation and storage burdens for terminals in wireless networks.The huge energy consumption of MEC servers challenges the establishment of smart cities and their service time powered by rechargeable batteries.In addition,Orthogonal Multiple Access(OMA)technique cannot utilize limited spectrum resources fully and efficiently.Therefore,Non-Orthogonal Multiple Access(NOMA)-based energy-efficient task scheduling among MEC servers for delay-constraint mobile applications is important,especially in highly-dynamic vehicular edge computing networks.The various movement patterns of vehicles lead to unbalanced offloading requirements and different load pressure for MEC servers.Self-Imitation Learning(SIL)-based Deep Reinforcement Learning(DRL)has emerged as a promising machine learning technique to break through obstacles in various research fields,especially in time-varying networks.In this paper,we first introduce related MEC technologies in vehicular networks.Then,we propose an energy-efficient approach for task scheduling in vehicular edge computing networks based on DRL,with the purpose of both guaranteeing the task latency requirement for multiple users and minimizing total energy consumption of MEC servers.Numerical results demonstrate that the proposed algorithm outperforms other methods. | Peiran Dong Zhaolong Ning Rong Ma Xiaojie Wang Xiping Hu Bin Hu | 2020 | China Communications2020，17，11： | 4 |
| 8 | Synthesis and light-emitting properties of 2-(N-phenyl-α-naphthylamino) and 2-dimesitylboron-7-(N-phenyl-α-naphthylamino)-9,9-diethylfluorene显示文摘A fluorescent organic triarylamine with a symmetric structure, 2,7-bis(N-α-naphthyl-phenylamino)-9,9- diethylfluorene (NPAEF) was synthesized using two methods, modified Ullmann coupling and modified palladium-catalyzed amination. An activated copper and a combination of Pd(OAc)2/P(t-Bu)3 and Pd(dba)2/P(t-Bu)3 were selected as catalysts to improve yields of reactions. These synthetic procedures were also successfully applied to an asymmetric 2-dimesitylboron-7-(N-phenyl-α-naphthylamino)-9,9-diethylfluorene (BNPEF). Photoluminescent emission peaks in solid film and in diluted solution of NPAEF were both observed at 461 nm, while the main emission peaks of BNPEF appeared at 422 nm in hexane, and at 480 nm in methanol. The double emission peaks of BNPEF in hexane reflected fine structure in the vibrational state. With an increasing polarity of solvent, the main PL emission peaks were red-shifted and vibrational fine structure disappeared. Additionally, energy levels of NPAEF were investigated and an electroluminescence (EL) device of ITO/PVK:NPAEF/Al was fabricated, which showed a turn-on voltage of 9 V and peaked at 462 nm. The EL spectrum was in good agreement with PL spectrum, which indicated that they were from the same emitting center in the device. | ZHANG WenGuan HE ZhiQun HUI GuanBao MU LinPing WANG YongSheng ZHAO ShengMin JING XiPing | 2009 | Science China Chemistry2009，52，7： | 3 |
| 9 | Mechanical defect identification for gas‐insulated switchgear equipment based on time‐frequency vibration signal analysis显示文摘Mechanical defect is an important reason for the failure of gas‐insulated switchgear(GIS)equipment.Based on the time‐frequency characteristic vibration signal analysis on five kinds of mechanical defects,a novel intelligent algorithm model combining complementary ensemble empirical mode decomposition(CEEMD)and genetic al-gorithm improved kernel fuzzy mean clustering(GAKFCM)was proposed to identify the mechanical defect type.First,the mechanical defect platform and detection sys-tem were built.Then CEEMD and IMF sensitivity factors were used to analyse the time‐frequency signal of five kinds of vibration defects,and the feature extraction was performed on the processed vibration signals.Finally,the mechanical vibration defect recognition model was established based on the GAKFCM algorithm and its validity was verified.Results show that the developed detection system can detect mechanical vibration signals sensitively.Singular values,frequency band lines and entropy can reflect the energy attenuation and distribution differences for different type of me-chanical defect vibration signals.The proposed GAKFCM clustering model combining the above vibration feature parameters can effectively find and diagnose the mechanical defect of GIS equipment.Its recognition accuracy reaches 96.74%,especially for the loose contact seat bolts and poor contact failures of the disconnector. | Yao Zhong Jian Hao Ruijin Liao Xupeng Wang Xiping Jiang Feng Wang | 2021 | High Voltage2021，6，3： | 3 |
| 10 | Strain rate sensitivity of tensile properties in high Nb containing TiAl alloys显示文摘The effect of strain rate on the yield strength of high Nb containing TiAl alloy was studied. The results show that the strain rate sensitivity varies with the test temperature, and the yield strength is not sensitive to the strain rate at room temperature but sig- nificantly sensitive to the strain rate at high temperature. An increase of the strain rate or a decrease of the temperature results in an obvious change of fracture mode. It is found that the strain rate sensitivity of this alloy varying with temperature is due to the dislo- cation climb generated at high temperature. | Jianfeng Gao Xiangjun Xu Junpin Lin Xiping Song Yanli Wang Guoliang Chen | 2005 | Journal of University of Science and Technology Beijing2005，12，6： | 2 |

| 12 | VlbZIP30 of grapevine functions in dehydration tolerance via the abscisic acid core signaling pathway显示文摘Drought stress limits the growth and development of grapevines,thereby reducing productivity,but the mechanisms by which grapevines respond to drought stress remain largely uncharacterized.Here,we characterized a group A bZIP gene from“Kyoho”grapevine,VlbZIP30,which was shown to be induced by abscisic acid(ABA)and dehydration stress.Overexpression of VlbZIP30 in transgenic Arabidopsis thaliana enhanced dehydration tolerance.Transcriptome analysis revealed that a major proportion of ABA-responsive and/or drought-responsive genes are transcriptionally regulated by VlbZIP30 during ABA or mannitol treatment at the cotyledon greening stage.We identified an A.thaliana G-box motif(CACGTG)and a potential grapevine G-box motif(MCACGTGK)in the promoters of the 39 selected A.thaliana genes upregulated in the transgenic plants and in the 35 grapevine homologs,respectively.Subsequently,using two grapevine-related databases,we found that 74%(23/31)and 84%(21/25)of the detected grapevine genes were significantly upregulated by ABA and drought stress,respectively,suggesting that these genes are involved in ABA or dehydration stress and may be regulated by VlbZIP30 in grapevine.We propose that VlbZIP30 functions as a positive regulator of dehydration-responsive signaling in the ABA core signaling pathway. | Mingxing Tu Xianhang Wang Yanxun Zhu Dejun Wang Xuechuan Zhang Ye Cui Yajuan Li Min Gao Zhi Li Yuejin Wang Xiping Wang | 2018 | Horticulture Research2018，5，1： | 2 |
| 13 | Increasing rainfed wheat yield by optimizing agronomic practices to consume more subsoil water in the Loess Plateau显示文摘Erratic rainfall and misalignment between the rainy season and the growing season of winter wheat greatly limit rainfed winter wheat yield in the Loess Plateau of China. To increase the grain yield of winter wheat in this region, the effects of different agronomic practices, including adjusting planting pattern(NR, narrow row spacing), increasing seeding rate(high seeding rate, HS), decreasing basal nitrogen rate and increasing top-dressed nitrogen rate(DBN), and replacing an old cultivar with a new cultivar(NC) on wheat yield were investigated for two consecutive years. The results showed that the current grain yield of rainfed winter wheat in the Loess Plateau could be increased to 5879–7093 kg ha^(-1) by HS, DBN and NC practices relative to the practice of high-yielding farmers(PF). The increased yield due to HS, DBN and NC was attributed to the higher number of spikes ha^(-1), 1000-grain weight, and kernels spike^(-1). Before the flowering stage, HS increased soil water consumption(SWC) in 1–3 m subsoil due to the higher plant population compared with that of PF, whereas DBN decreased SWC in the 0–2 m soil layer compared with that of PF. After the flowering stage, HS, DBN, and NC increased SWC by 8–16 mm in 2–3 m subsoil compared to PF. The water use efficiency(WUE) was increased under DBN and NC in comparison with PF.However, the WUE did not increase under HS as it had the highest evapotranspiration among the five treatments. Increasing the use of subsoil water during the late growth stage by optimizing agronomic practices or applying new cultivars with expansive roots should be the primary approach to increase rainfed winter wheat yield in this region. | Wenjia Yang Weijian Liu Yulin Li Shiwen Wang Lina Yin Xiping Deng | 2021 | The Crop Journal2021，9，6： | 2 |
| 14 | VqMYB154 promotes polygene expression and enhances resistance to pathogens in Chinese wild grapevine显示文摘Resveratrol plays a crucial phytoalexin role in the grapevine and is beneficial to human health.However,the molecular mechanism of resveratrol accumulation in the enhancement of disease resistance is unclear.Here,we report that the transcription factor VqMYB154 from Vitis quinquangularis accession Danfeng-2 is strongly expressed under artificial inoculation with Uncinula necator and regulates resveratrol accumulation.Unlike its homolog,VqMYB154 has a pathogen-induced promoter and responds to stimulation by U.necator,Pseudomonas syringae,and other treatments.Yeast one-hybrid and GUS activity assays confirmed that VqMYB154 can activate the stilbene synthase genes VqSTS9,VqSTS32,and VqSTS42 by directly binding to their promoters.Overexpression of VqMYB154 in grape leaves resulted in activation of the stilbene pathway,upregulation of STS genes,and accumulation of stilbenoids.In addition,heterologous overexpression of VqMYB154 in Arabidopsis activated resistance-related genes and resulted in greater programmed cell death and accumulation of reactive oxygen species,which led to resistance against P.syringae.These results suggest that the transcription factor VqMYB154 from V.quinquangularis accession Danfeng-2 participates in the regulatory mechanism that improves the biosynthesis and accumulation of stilbenes and enhances resistance to disease in grapevine. | Changyue Jiang Dan Wang Jie Zhang Yan Xu Chaohong Zhang Jianxia Zhang Xiping Wang Yuejin Wang | 2021 | Horticulture Research2021，8，1： | 2 |
| 15 | Detection of QTL and QTN and candidate genes for oil content in soybean using a combination of four-way-RIL and germplasm populations显示文摘Soybean is a source of edible oil for humans and provides a third of the vegetable oil consumed worldwide.Increasing seed oil content in seeds is thus a key objective in soybean breeding.In the present study,a four-way recombinant inbred line(FW-RIL)population comprising 144 lines,planted in 10 environments,and a germplasm panel of 455 accessions,planted in two environments,were used to collect oil-content phenotypes.First,59 quantitative trait loci(QTL)were detected in the FW-RIL population by inclusive complete interval mapping on a linkage map consisting of 2232 single-nucleotide polymorphism(SNP)markers.Also in the FW-RILs,44 quantitative trait nucleotides(QTNs)were detected by association analysis using 109,676 SNP markers and fivemethods of multi-locus genome-wide association study.Second,77 QTN were detected by association analysis in the germplasm panel using 63,306 markers.Comparison of the QTL and QTN suggested four QTN controlling oil content.Pathway analysis was performed on genes in attenuation regions of these four QTN,and two candidate genes involved in the synthesis or metabolism of soybean oil were identified.These findings provide useful information about the genetics of oil content and may contribute to its genetic improvement by marker-assisted selection. | Xiyu Li Kaixin Zhang Xu Sun Shanshan Huang Jiajing Wang Chang Yang Mahfishan Siyal Chao Wang Chunlan Guo Xiping Hu Wen-Xia Li Hailong Ning | 2020 | The Crop Journal2020，8，5： | 2 |
