| 2 | Fabrication,microstructures,and properties of copper matrix composites reinforced by molybdenum-coated carbon nanotubes显示文摘Multiwalled carbon nanotubes(CNTs) were coated by a molybdenum layer using carbonyl thermal decomposition process with a precursor of molybdenum hexacarbonyl.The Mo-coated CNTs(Mo-CNTs) were added into copper powders to fabricate Mo-CNT/Cu composites by means of mechanical milling followed by spark plasma sintering.The Mo-CNTs were uniform dispersion in the Cu matrix when their contents were 2.5 vol.%-7.5 vol.%,while some Mo-CNT clusters were clearly observed at additions of 10.0 vol.%-15.0 vol.% Mo-CNTs in the mixture.The mechanical,electrical,and thermal properties of the Mo-CNT/Cu composites were characterized,and the results showed that the tensile strength and hardness were 2.0 and 2.2 times higher than those of CNT-free specimens,respectively.Moreover,the Mo-CNT/Cu composites exhibited an enhanced thermal conductivity but inferior electrical conductivity compared with sintered pure Cu.The uncoated CNT/Cu composites were fabricated by the similar processes,and the measured tensile strength,hardness,thermal conductivity,and electrical conductivity of the CNT/Cu composites were lower than those of the Mo-CNT/Cu composites. | NIE Junhui JIA Chengchang JIA Xian ZHANG Yafeng SHI Na LI Yi | 2011 | Rare Metals2011,30,4: | 12 |
| 3 | Fault self-repair strategy based on evolvable hardware and reparation balance technology显示文摘In the face of harsh natural environment applications such as earth-orbiting and deep space satellites, underwater sea vehicles, strong electromagnetic interference and temperature stress,the circuits faults appear easily. Circuit faults will inevitably lead to serious losses of availability or impeded mission success without self-repair over the mission duration. Traditional fault-repair methods based on redundant fault-tolerant technique are straightforward to implement, yet their area, power and weight cost can be excessive. Moreover they utilize all plug-in or component level circuits to realize redundant backup, such that their applicability is limited. Hence, a novel selfrepair technology based on evolvable hardware(EHW) and reparation balance technology(RBT) is proposed. Its cost is low, and fault self-repair of various circuits and devices can be realized through dynamic configuration. Making full use of the fault signals, correcting circuit can be found through EHW technique to realize the balance and compensation of the fault output-signals. In this paper, the self-repair model was analyzed which based on EHW and RBT technique, the specific self-repair strategy was studied, the corresponding self-repair circuit fault system was designed, and the typical faults were simulated and analyzed which combined with the actual electronic devices. Simulation results demonstrated that the proposed fault self-repair strategy was feasible. Compared to traditional techniques, fault self-repair based on EHW consumes fewer hardware resources, and the scope of fault self-repair was expanded significantly. | Zhang Junbin Cai Jinyan Meng Yafeng Meng Tianzhen | 2014 | Chinese Journal of Aeronautics2014,27,5: | 10 |

| 5 | Difference between grid connections of large-scale wind power and conventional synchronous generation显示文摘In China, regions with abundant wind energy resources are generally located at the end of power grids. The power grid architecture in these regions is typically not sufficiently strong, and the energy structure is relatively simple. Thus, connecting large-capacity wind power units complicates the peak load regulation and stable operation of the power grids in these regions. Most wind turbines use power electronic converter technology, which affects the safety and stability of the power grid differently compared with conventional synchronous generators. Furthermore, fluctuations in wind power cause fluctuations in the output of wind farms, making it difficult to create and implement suitable power generation plans for wind farms. The generation technology and grid connection scheme for wind power and conventional thermal power generation differ considerably. Moreover, the active and reactive power control abilities of wind turbines are weaker than those of thermal power units, necessitating additional equipment to control wind turbines. Hence, to address the aforementioned issues with large-scale wind power generation, this study analyzes the differences between the grid connection and collection strategies for wind power bases and thermal power plants. Based on this analysis, the differences in the power control modes of wind power and thermal power are further investigated. Finally, the stability of different control modes is analyzed through simulation. The findings can be beneficial for the planning and development of large-scale wind power generation farms. | Jie Li Chao Liu Pengfei Zhang Yafeng Wang Jun Rong | 2020 | Global Energy Interconnection2020,3,5: | 7 |
| 6 | Spatio-Temporal Impact of Rural Livelihood Capital on Labor Migra- tion in Panxi, Southwestern Mountainous Region of China显示文摘Labor migration to urban centers is a common phenomenon in the Panxi region of the southwestern mountainous region of China, mainly owing to inadequate livelihood capital in rural areas. Numerous studies have been conducted to explore the relationship between labor migration and its causes, such as individual and family characteristics, but few studies have focused on livelihood capital. This paper examines the impact factors on labor migration employment location selection and duration from a household livelihood capital perspective. A case study of 279 households from 10 villages in the area was carried out in February 2016. We used both qualitative and quantitative methods to analyze the data. On the basis of the 279 questionnaires, the proportion of households with non-labor migration is 48.4%, whereas households with labor migration within a local city and migration across regions account for 28.7% and 22.9%, respectively. Social, financial, and human capitals are the primary factors that influence migrants' employment location choice positively. Among them, social capital has a significant impact on both migration within a local city and across regions; each of the regression coefficients is 1.111 and 1.183. Social, human, and financial capitals also have a positive impact on the duration of labor migration, and similarly, social capital is the highest coefficient with 2.489. However, physical capital only partly impacts labor migration across regions, whereas the impact of labor migration within a local city, and the duration, are not significant. Furthermore, the impact of household natural capital on migration space and time are all negative relationships, especially for labor migration across the regions and duration, with coefficient scores of 4.836 and 3.450, respectively. That is to say, a laborer is inclined to migrate within a local city for a short term, or not migrate at all, if natural capital is abundant. Our analysis results show that household livelihood capital has a strong spatio-temporal impact on labor migration. | WAN Jiangjun DENG Wei SONG Xueqian LIU Ying ZHANG Shaoyao SU Yi LU Yafeng | 2018 | Chinese Geographical Science2018,28,1: | 5 |
| 7 | Processing of a Novel Zn Alloy Micro-Tube for Biodegradable Vascular Stent Application显示文摘In recent years, zinc based alloys as a new biodegradable metal material aroused intensive interests.However, the processing of Zn alloys micro-tubes(named slender-diameter and thin-walled tubes) is very difficult due to their HCP crystal structure and unfavorable mechanical properties. This study aimed to develop a novel technique to produce micro-tube of Zn alloy with good performance for biodegradable vascular stent application. In the present work, a processing method that combined drilling, cold rolling and optimized drawing was proposed to produce the novel Zn–5Mg–1Fe(wt%) alloy microtubes. The micro-tube with outer diameter of 2.5 mm and thickness of 130 μm was fabricated by this method and its dimension errors are within 10 μm. The micro-tube exhibits a fine and homogeneous microstructure, and the ultimate tensile strength and ductility are more than 220 MPa and 20% respectively. In addition, the micro-tube and stents of Zn alloy exhibit superior in vitro corrosion and expansion performance. It could be concluded that the novel Zn alloy micro-tube fabricated by above method might be a promising candidate material for biodegradable stent. | Chang Wang Zhentao Yu Yajun Cui Yafeng Zhang Sen Yu Gongqi Qu Haibo Gong | 2016 | Journal of Materials Science & Technology2016,32,9: | 5 |
| 8 | Influence of the quickness and duration of De Qi on the analgesic effect of acupuncture in primary dysmenorrhea patients with a cold and dampness stagnation pattern显示文摘OBJECTIVE: To investigate the influence of the quickness and duration of De Qi(or Qi arrival) on the analgesic effect of acupuncture in primary dysmenorrhea patients with a cold and dampness stagnation pattern.METHODS: Sixty-eight patients were randomly assigned to the De Qi group(deep needling with thick needles and manipulation, n = 17) or the non-De Qi group(shallow needling with thin needles and no manipulation, n = 51). Both groups underwent needling at Sanyinjiao(SP 6) for 30 min.The visual analogue scale was used to measure the degree of menstrual pain, and the Acupuncture De Qi Clinical Assessment Scale was used to assess De Qi. Only data from patients who experienced actual De Qi were included in the analysis.RESULTS: Thirty-nine patients experienced actual De Qi. Patients who experienced actual De Qi in the De Qi group(n = 14) felt De Qi more rapidly(P =0.028) and for a longer duration(P = 0.04) than patients who experienced actual De Qi in the non-De Qi group(n = 25). Both groups showed a reduction in the visual analogue scale score for pain after treatment. The analgesic effect did not significantly differ between the two groups. The occurrence time of De Qi showed a significant negative correlation with pain reduction at 20 and 30 min after needle removal(P < 0.05). There was no correlation between the duration of De Qi and the therapeutic effect.CONCLUSION: In primary dysmenorrhea patients with a cold and dampness stagnation pattern,quicker onset of De Qi when needling Sanyinjiao(SP 6) achieves a better analgesic outcome. However, a longer duration of De Qi does not affect the degree of analgesia. Compared with minimal acupuncture, active acupuncture stimulation achieves a more rapid onset and longer duration of De Qi. | Hu Nijuan Ma Liangxiao Wang Pei Wu Guiwen Zhao Minyi Hu Shangqing Sun Junjun Wang Yafeng Zhang Zhuang Zhu Jiang | 2019 | Journal of Traditional Chinese Medicine2019,39,2: | 4 |
| 9 | Friction and wear properties of copper matrix composites reinforced by tungsten-coated carbon nanotubes显示文摘Carbon nanotubes (CNTs) were coated by tungsten layer using metal organic chemical vapor deposition process with tungsten hexacarbonyl as a precursor. The W-coated CNTs (W-CNTs) were dispersed into Cu powders by magnetic stirring process and then the mixed powders were consolidated by spark plasma sintering to fabricate W-CNTs/Cu composites. The CNTs/Cu composites were fabricated using the simi-lar processes. The friction coefficient and mass wear loss of W-CNTs/Cu and CNTs/Cu composites were studied. The results showed that the W-CNT content, interfacial bonding situation, and applied load could influence the friction coefficient and wear loss of W-CNTs/Cu com-posites. When the W-CNT content was 1.0 wt.%, the W-CNTs/Cu composites got the minimum friction coefficient and wear loss, which were decreased by 72.1% and 47.6%, respectively, compared with pure Cu specimen. The friction coefficient and wear loss of W-CNTs/Cu composites were lower than those of CNTs/Cu composites, which was due to that the interfacial bonding at (W-CNTs)-Cu interface was bet-ter than that at CNTs-Cu interface. The friction coefficient of composites did not vary obviously with increasing applied load, while the wear loss of composites increased significantly with the increase of applied load. | NIE Junhui JIA Xian JIA Chengchang LI Yi ZHANG Yafeng SHI Na | 2011 | Rare Metals2011,30,6: | 3 |
| 10 | Substrates and interlayer coupling effects on Mo1-xWxSe2 alloys显示文摘Two-dimensional(2D) transition metal dichalcogenides alloys are potential materials in the application of photodetectors over a wide spectral range due to their composition-dependent bandgaps. The study of bandgap engineering is important for the application of 2D materials in devices. Here, we grow the Mo1-xWxSe2 alloys on mica, sapphire and SiO2/Si substrates by chemical vapor deposition(CVD) method. Mo1-x Wx Se2 alloys are grown on the mica substrates by CVD method for the first time. Photoluminescence(PL) spectroscopy is used to investigate the effects of substrates and interlayer coupling force on the optical bandgaps of as-grown Mo1-xWxSe2 alloys. We find that the substrates used in this work have an ignorable effect on the optical bandgaps of as-grown Mo1-xWxSe2. The interlayer coupling effect on the optical bandgaps of as-grown Mo1-xWxSe2 is larger than the substrates effect. These findings provide a new way for the future study of the growth and physical properties of 2D alloy materials. | Fang Liang Hejun Xu Zuoyuan Dong Yafeng Xie Chen Luo Yin Xia Jian Zhang Jun Wang Xing Wu | 2019 | Journal of Semiconductors2019,40,6: | 2 |
| 11 | Influence of Shot Peening Treatment on the Fatigue and Corrosion Resisting Properties of 2Cr13 Stainless Steel显示文摘In the present paper,shot peening treatments were used to strengthen the steel surface,and the influence on the fatigue and corrosion resisting properties of 2Cr13 stainless steel was examined.The residual stress and the surface roughness were investigated by XRD and AFM.The characteristics of fatigue and corrosion resistance have also been analyzed by bending fatigue and salt spray tests.The result reveals that the fatigue limit of the samples is improved dramatically with the increasing of the peening strength by 7.5%.Meanwhile,the peenging angle has no evident influence on the fatigue properties.Compared with the untreated samples,the acid corrosion weight loss of the samples after the shot peening treatment is decreased almost by 90%.From the above experimental results proper shot peening would improve not only the fatigue property but also the corrosion resistance of 2Cr13-typed stainless steel. | Liu Mingxia Zhang Haicun Liu Daoxin Han Zengfu Zhi Jinhua Guo Wenyong Zhou Yafeng | 2012 | 稀有金属材料与工程2012,41,S1: | 2 |
| 12 | Finding Deceptive Opinion Spam by Correcting the Mislabeled Instances显示文摘Assessing the trustworthiness of reviews is a key in natural language processing and computational linguistics. Previous work mainly focuses on some heuristic strategies or simple supervised learning methods, which limit the performance of this task. This paper presents a new approach, from the viewpoint of correcting the mislabeled instances, to find deceptive opinion spam. Partition a dataset into several subsets, construct a classifier set for each subset and select the best one to evaluate the whole dataset. Error variables are defined to compute the probability that the instances have been mislabeled. The mislabeled instances are corrected based on two threshold schemes, ma jority and non-objection. The results display significant improvements in our method in contrast to the existing baselines. | REN Yafeng JI Donghong YIN Lan ZHANG Hongbin | 2015 | Chinese Journal of Electronics2015,24,1: | 2 |

| 16 | A NEW ALGORITHM FOR MAIN CARRIER ACQUISITION IN DEEP SPACE COMMUNICATIONS显示文摘Compared with common near space satellite Telemetry,Telecommand,and Communication(TT&C),deep space TT&C presents a more challenging environment such as long distance,very low Signal to Noise Ratio(SNR).How to acquire main carrier exactly becomes a hot focus for deep space communications.Already there emerged some main carrier acquisition algorithms,but they all require high SNR and small modulation index.In this paper,we develop a new acquire algorithm.First we use the spectral energy center algorithm to shorten the original sequence,filter out some noise and make the spectral more symmetric.Then we adopt the spectral symmetry algorithm to make full use of the whole spectrum information,and utilize FFT to reduce computation complexity.Simulation results show that our algorithm can acquire main carrier successfully under large modulation index and get good performance with low Carrier to Noise Ratio(CNR). | Zhang Ruyuan Zhan Yafeng Lu Jianhua | 2011 | Journal of Electronics(China)2011,28,2: | 2 |

| 18 | Generation of transgenic wheat resistant to wheat yellow mosaic virus and identification of gene silence induced by virus infection显示文摘The plasmid containing the promoter Actl, the coat protein (cp) gene of wheat yellow mosaic virus (WYMV) and the selectable bar gene, was delivered via particle bombardment, directly into immature embryos of a wheat culti-vars. PCR and PCR-RFLP were employed to screen the existence of the cp gene in T0 and T1 generations. Seeds from the positive T1 plants were sowed in fields heavily contaminated with WYMV to detect their resistance. In field trial of virus infection, one of the transgenic wheat lines, P8-T2, exhibited highly disease-resistance. Western blot and RT-PCR analysis showed that the expression level of cp gene in the resistant transgenic line was reduced greatly compared to those susceptible to WYMV infection. This provided evidence to presume that the resistance obtained by the transgenic wheat line was stimulated by the mechanism of the virus induced gene silencing. | DONG Jin HE Zhentian HAN Chenggui CHEN Xiulan ZHANG Lingdi LIU Weihua HAN Yuepeng WANG Jinrong ZHAI Yafeng YU Jialin LIU Yi XIAO Yueyan | 2002 | Chinese Science Bulletin2002,47,17: | 2 |
