| 2 | Time-frequency analysis and detecting method research on milling force token signal in spindle current signal显示文摘The vast majority of tool condition monitoring systems use the motor current instead of the cutting force as the predictor signal. The measured motor current signal is time-dependant and instable. It is difficult to detect the cutting force token signal from such motor current signal. This paper presents a method that uses the wavelet transforms to reconstruct the cutting force token signal from the current signal based on the time frequency analysis of the cutting force signal. The result of the cutting force measurement experiment shows that the proposed reconstruct method could be used to analyze the spindle current and monitor the time-varying cutting force. | MAO XinYong LIU HongQi LI Bin | 2009 | Science China(Technological Sciences)2009，52，10： | 11 |
| 3 | Synthesis and characterization of PMMA/Al_2O_3 composite particles by in situ emulsion polymerization显示文摘In order to improve its dispersibility,superfine alumina(Al2O3) was encapsulated with poly(methyl methacrylate)(PMMA) by in situ emulsion polymerization.It was found that only when the concentration of sodium dodecyl sulfate(SDS) was much higher than its critical micelle concen-tration,could PMMA/Al2O3 composite particles with high percentage of grafting(PG) be prepared.The same results were obtained between the experimental and stoichiometric amounts of tris(dodecylbenzenesulfonate) isopropoxide(NDZ),indicating that single-molecule-layer adsorption had taken place between NDZ and Al2O3.Analysis using FTIR,TEM and XPS showed that PMMA/Al2O3 composite particles with core-shell structure had been successfully synthesized by in situ emulsion polymerization.Compared to Al2O3,thermal stability and dispersibility of the composite particles showed marked improvement. | Hui Liu Hongqi Ye Tianquan Lin Tao Zhou | 2008 | Particuology2008，6，3： | 9 |
| 4 | Axonal remodeling of the corticospinal tract during neurological recovery after stroke显示文摘Stroke remains the leading cause of long-term disability.Hemiparesis is one of the most common post-stroke motor deficits and is largely attributed to loss or disruption of the motor signals from the affected motor cortex.As the only direct descending motor pathway,the corticospinal tract(CST)is the primary pathway to innervate spinal motor neurons,and thus,forms the neuroanatomical basis to control the peripheral muscles for voluntary movements.Here,we review evidence from both experimental animals and stroke patients,regarding CST axonal damage,functional contribution of CST axonal integrity and remodeling to neurological recovery,and therapeutic approaches aimed to enhance CST axonal remodeling after stroke.The new insights gleaned from preclinical and clinical studies may encourage the development of more rational therapeutics with a strategy targeted to promote axonal rewiring for corticospinal innervation,which will significantly impact the current clinical needs of subacute and chronic stroke treatment. | Zhongwu Liu Hongqi Xin Michael Chopp | 2021 | Neural Regeneration Research2021，16，5： | 6 |
| 5 | Micro-geological causes and macro-geological controlling factors of low-resistivity oil layers in the Puao Oilfield显示文摘Low-resistivity oil layers are often missed in logging interpretation because of their resistivity close to or below the resistivity of nearby water layers.Typical low-resistivity oil layers have been found in the past few years in the Putaohua reservoir of the Puao Oilfield in the south of the Daqing placanticline by detailed exploration.Based on a study of micro-geological causes of low-resistivity oil layers,the macro-geological controlling factors were analyzed through comprehensive research of regional depositional background,geological structure,and oil-water relations combined with core,water testing,well logging,and scanning electron microscopy data.The results showed that the formation and distribution of Putaohua low-resistivity oil layers in the Puao Oilfield were controlled by depositional environment,sedimentary facies,diagenesis,motive power of hydrocarbon accumulation,and acidity and alkalinity of reservoir liquid.The low-resistivity oil layers caused by high bound-water saturation were controlled by deposition and diagenesis,those caused by high free-water saturation were controlled by structural amplitude and motive power of hydrocarbon accumulation.Those caused by formation water with high salinity were controlled by the ancient saline water depositional environment and faulted structure and those caused by additional conductivity of shale were controlled by paleoclimate and acidity and alkalinity of reservoir liquid.Consideration of both micro-geological causes and macro-geological controlling factors is important in identifying low-resistivity oil layers. | Tan Fengqi Li Hongqi Liu Hongtao Jiang Fucong Yu Hongyan | 2009 | Petroleum Science2009，6，3： | 5 |
| 6 | Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19. | Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 5 |
| 7 | Near infrared spectral and polarization imaging observation of coronal emission lines during the 2008 total solar eclipse显示文摘During the 2008 total solar eclipse, the coronal emission lines were observed by using optical fibre spectrometric and polarization imaging system in near infrared waveband. The profiles of the coronal emission lines including Fe XIII 10747 , 10798 and He I 10830 were obtained with dispersion of 0.5 /pix. The intensity of Fe XIII 10747 remained unchanged in the two different coronal regions while the intensity of He I 10830 varied considerably in the two coronal locations no matter whether the prominence appeared or not. The coronal polarization images were observed at Fe XI 7892 with a bandpass of 30 in a series of exposure times. | BAO XingMing ZHANG ZhiYong DENG Jian HU KeLiang XUAN WeiJia LIU YangBing ZHANG HongQi DENG YuanYong WANG DongGuang WANG XiaoFan | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，11： | 5 |
| 8 | Digital zenith telescope prototype of China显示文摘Classical optical astronomy measures the direction of the local plumb line on the stellar background,and is influenced by variations of the earth gravity field.Therefore,classical optical astrometry can be used to measure and study variations of plumb line.This endows classical optical astrometric technologies special significance for the interdisciplinary researches of astronomy and geoscience,and makes them irreplaceable by technologies like very long baseline interferometry,satellite laser ranging.However,classical astrometric instruments have a major drawback of low efficiency,such as the low automaticity,more operating observers,and even operative error which makes it very difficult to reduce the random observation error in some visual instruments.To overcome this drawback,we have successfully developed the digital zenith telescope prototype(DZT-1)with the aperture of200 mm,using charge coupled device and other advanced technologies and new equipments.As proved by test observations,DZT-1 can observe thousands of stars over one night,which significantly reduces the random observation error and increases the observation accuracy.In addition,DZT-1 has a high degree of automation,even allowing unattended observation by remote control.Besides,DZT-1 has a small-size and is easy to move,making it convenient for mobile measurement of the deflection of the vertical.In summary,DZT can be widely used in the geoscience and astronomy fields. | Lili Tian Jinyun Guo Yanben Han Xiushan Lu Weidong Liu Zheng Wang Bo Wang Zhiqiang Yin Hongqi Wang | 2014 | Chinese Science Bulletin2014，59，17： | 4 |
| 9 | Multi-function radar emitter identification based on stochastic syntax-directed translation schema显示文摘To cope with the problem of emitter identification caused by the radar words' uncertainty of measured multi-function radar emitters, this paper proposes a new identification method based on stochastic syntax-directed translation schema(SSDTS). This method, which is deduced from the syntactic modeling of multi-function radars, considers the probabilities of radar phrases appearance in different radar modes as well as the probabilities of radar word errors occurrence in different radar phrases. It concludes that the proposed method can not only correct the defective radar words by using the stochastic translation schema, but also identify the real radar phrases and working modes of measured emitters concurrently. Furthermore, a number of simulations are presented to demonstrate the identification capability and adaptability of the SSDTS algorithm.The results show that even under the condition of the defective radar words distorted by noise,the proposed algorithm can infer the phrases, work modes and types of measured emitters correctly. | Liu Haijun Yu Hongqi Sun Zhaolin Diao Jietao | 2014 | Chinese Journal of Aeronautics2014，27，6： | 4 |

| 11 | BURST-LDA: A NEW TOPIC MODEL FOR DETECTING BURSTY TOPICS FROM STREAM TEXT显示文摘Topic models such as Latent Dirichlet Allocation(LDA) have been successfully applied to many text mining tasks for extracting topics embedded in corpora. However, existing topic models generally cannot discover bursty topics that experience a sudden increase during a period of time. In this paper, we propose a new topic model named Burst-LDA, which simultaneously discovers topics and reveals their burstiness through explicitly modeling each topic's burst states with a first order Markov chain and using the chain to generate the topic proportion of documents in a Logistic Normal fashion. A Gibbs sampling algorithm is developed for the posterior inference of the proposed model. Experimental results on a news data set show our model can efficiently discover bursty topics, outperforming the state-of-the-art method. | Qi Xiang Huang Yu Chen Ziyan Liu Xiaoyan Tian Jing Huang Tinglei Wang Hongqi | 2014 | Journal of Electronics(China)2014，31，6： | 3 |
| 12 | Researching the 915 nm high-power and high-brightness semiconductor laser single chip coupling module显示文摘Based on the high-speed development of the fiber laser in recent years, the development of researching 915 nm semiconductor laser as main pumping sources of the fiber laser is at a high speed. Because the beam quality of the laser diode is very poor, the 915 nm laser diode is generally based on optical fiber coupling module to output the laser. Using the beam-shaping and fiber-coupling technology to improve the quality of output beam light, we present a kind of high-power and high-brightness semiconductor laser module, which can output 13.22 W through the optical fiber. Based on 915 nm GaAs semiconductor laser diode which has output power of 13.91 W, we describe a thoroughly detailed procedure for reshaping the beam output from the semiconductor laser diode and coupling the beam into the optical fiber of which the core diameter is 105 μm and the numerical aperture is 0.18. We get 13.22 W from the output fiber of the module at 14.5 A, the coupling efficiency of the whole module is 95.03% and the brightness is 1.5 MW/cm^2 -str. The output power of the single chip semiconductor laser module achieves the advanced level in the domestic use. | Xin Wang Cuiluan Wang Xia Wu Lingni Zhu Hongqi Jing Xiaoyu Ma Suping Liu | 2017 | Journal of Semiconductors2017，38，2： | 3 |
| 13 | A Text Similarity Measurement Based on Semantic Fingerprint of Characteristic Phrases显示文摘Text similarity measurements are the basis for measuring the degree of matching between two or more texts. Traditional large-scale similarity detection methods based on a digital fingerprint have the advantage of high detection speed, which are only suitable for accurate detection. We propose a method of Chinese text similarity measurement based on feature phrase semantics.Natural language processing(NLP) technology is used to pre-process text and extract the keywords by the Term frequency-Inverse document frequency(TF-IDF) model and further screen out the feature words. We get the exact meaning of a word and semantic similarities between words and a How Net semantic dictionary. We substitute concepts to get the feature phrases and generate a semantic fingerprint and calculate similarity. The experimental results indicate that the method proposed is superior in similarity detection in terms of its accuracy rate,recall rate, and F-value to the traditional and digital fingerprinting method. | PANG Shanchen YAO Jiamin LIU Ting ZHAO Hua CHEN Hongqi | 2020 | Chinese Journal of Electronics2020，29，2： | 3 |
| 14 | Tribological properties of M0S_(2) coating for ultra-long wear-life and low coefficient of friction combined with additive g-C3N4 in air显示文摘The solid lubricant M0S_(2) demonstrates excellent lubricating properties,but it spontaneously oxidizes and absorbs moisture in air,and thus results in poor wear resistance and short wear-life.In this study,the additive g-C_(3)N_(4)(CN)was successfully combined with M0S_(2) via hydrothermal synthesis as a solid lubricant for the first time.Meanwhile,a low friction coefficient(COF,y=0.031)and ultra-long wear-life of CN/M0S_(2) compared to pure M0S_(2) in air were demonstrated.The functional groups and good crystallinity of the lubricant material were characterized via Fourier transform infrared(FTIR)spectroscopy and X-ray diffraction(XRD).The formed valence states in CN/M0S_(2) were analyzed via X-ray photoelectron spectroscopy(XPS).The characterized results of the scanning electron microscopy(SEM)and high-resolution transmission electron microscopy(HRTEM)show the morphology and interior crystal phase structure of CN/M0S_(2).From the cross-section analysis,the presence of iron oxide nanoparticles lubricating film is synergistic with CN/M0S_(2) film during the friction process,resulting in its ultra-long wear-life.In particular,the friction mechanism of interlayer sliding friction combined with energy storage friction was analyzed and proposed. | Yupeng ZHANG Panpan LI Li JI Xiaohong LIU Hongqi WAN Lei CHEN Hongxuan LI Zhiiiang JIN | 2021 | Friction2021，9，4： | 3 |

| 16 | Location and size regulation of manganese oxides within mesoporous silica for enhanced antibiotic degradation显示文摘Refractory antibiotics in domestic wastewater are hard to be completely eliminated by conventional methods,and then lead to severe environmental contamination and adverse effects on public health.In present work,advanced oxidation processes(AOPs)are adopted to remove the antibiotic of sul-fachloropyridazine(SCP).Nanosized Mn_(2)O_(3) was fabricated on the SBA-15 material to catalytically acti-vate potassium peroxydisulfate(PDS)to generate reactive oxygen radicals of.OH and SO_(4).for SCP degradation.The effects of location and size of Mn_(2)O_(3) were explored through choosing either the as-made or template free SBA-15 as the precursor of substrate.Great influences from the site and size of Mn_(2)O_(3) on the oxidation activity were discovered.It was found that Mn_(2)O_(3) with a large size at the exterior of SBA-15(Mn-tfSBA)was slightly easier to degrade SCP at a low manganese loading of 1.0-2.0 mmol.g;however,complete SCP removal could only be achieved on the catalyst of Mn_(2)O_(3) with a refined size at the interior of SBA-15(Mn-asSBA).Moreover,the SO_(4).species were revealed to be the decisive radicals in the SCP degradation processes.Exploring the as-made mesoporous silica as a support provides a new idea for the further development of environmentally friendly catalysts. | Min Lu Mengxuan Liu Chunli Xu Yu Yin Lei Shi Hong Wu Aihua Yuan Xiao-Ming Ren Shaobin Wang Hongqi Sun | 2022 | Chinese Journal of Chemical Engineering2022，35，8： | 3 |
| 17 | Image and data processing of digital zenith telescope(DZT-1) of China显示文摘The first digital zenith telescope prototype(DZT-1)of China was successfully developed by National Astronomical Observatories,Chinese Academy of Sciences and Shandong University of Science and Technology at the end of 2011.Compared with classical astrometric telescopes,DZT-1 has features of small size,high automation,and high accuracy.It can be used to do classical astrometric observations as well as measurement of plumb line variation and deflection of the vertical.So DZT-1 plays a significant role in astronomy and geoscience.Although the measurement principle and method of DZT-1 are somewhat similar to classical photographic zenith tube,there are still many differences.The present paper introduces the principle,method,and procedure for processing DZT-1 star image and data,as well as the application software for astronomical latitude and longitude calculation using DZT-1 observations.The test observations and the observation results are also presented.According to the test observation results,the standard deviation of single observation is about 0.200–0.300,and 0.0700–0.0800in term of a group observations.In conclusion,the data processing software fulfills DZT-1’s demand for data processing,guaranteeing the automation and high accuracy for DZT-1. | Bo Wang Lili Tian Zheng Wang Zhiqiang Yin Weidong Liu Qiyuan Qiao Hongqi Wang Yanben Han | 2014 | Chinese Science Bulletin2014，59，17： | 2 |
| 18 | Nitrogen-doped Carbon Nanospheres-Modified Graphitic Carbon Nitride with Outstanding Photocatalytic Activity显示文摘Metals and metal oxides are widely used as photo/electro-catalysts for environmental remediation.However,there are many issues related to these metal-based catalysts for practical applications,such as high cost and detrimental environmental impact due to metal leaching.Carbon-based catalysts have the potential to overcome these limitations.In this study,monodisperse nitrogen-doped carbon nanospheres(NCs)were synthesized and loaded onto graphitic carbon nitride(g-C3N4,GCN)via a facile hydrothermal method for photocatalytic removal of sulfachloropyridazine(SCP).The prepared metal-free GCN-NC exhibited remarkably enhanced efficiency in SCP degradation.The nitrogen content in NC critically influences the physicochemical properties and performances of the resultant hybrids.The optimum nitrogen doping concentration was identified at 6.0 wt%.The SCP removal rates can be improved by a factor of 4.7 and 3.2,under UV and visible lights,by the GCN-NC composite due to the enhanced charge mobility and visible light harvesting.The mechanism of the improved photocatalytic performance and band structure alternation were further investigated by density functional theory(DFT)calculations.The DFT results confirm the high capability of the GCN-NC hybrids to activate the electron–hole pairs by reducing the band gap energy and efficiently separating electron/hole pairs.Superoxide and hydroxyl radicals are subsequently produced,leading to the efficient SCP removal. | Qiaoran Liu Hao Tian Zhenghua Dai Hongqi Sun Jian Liu Zhimin Ao Shaobin Wang Chen Han Shaomin Liu | 2020 | Nano-Micro Letters2020，12，2： | 2 |

| 20 | A multi-step induced strategy to fabricate core-shell Pt-Ni alloy as symmetric electrocatalysts for overall water splitting显示文摘Devising an electrocatalyst with brilliant efficiency and satisfactory durability for hydrogen production is of considerable demand,especially for large-scale application.Herein,we adopt a multi-step consequential induced strategy to construct a bifunctional electrocatalyst for the overall water splitting.Graphene oxide(GO)was used as a carbon matrix and in situ oxygen source,which was supported by the octahedral PtNi alloy to form the PtxNiy-GO precursor.When calcinating in Ar atmosphere,the oxygen in GO induced the surface segregation of Ni from the PtNi octahedron to form a core-shell structure of Ptx@Niy.Then,the surface-enriched Ni continuously induced the reformation of C in reduced graphene oxide(rGO)to enhance the degree of graphitization.This multi-step induction formed a nanocatalyst Pt_(x)@Ni_(y)-rGO which has very high catalytic efficiency and stability.By optimizing the feeding ratio of PtNi(Pt:Ni=1:2),the electrolytic overall water splitting at 10 mA·cm^(-2) can be driven by an electrolytic voltage of as low as 1.485 V,and hydrogen evolution reaction(HER)only needs an overpotential of 37 mV in 1.0 M KOH aqueous solution.Additionally,the catalyst exhibited consistent existence form in both HER and oxygen evolution reaction(OER),which was verified by switching the anode and cathode of the cell in the electrolysis of water.This work provides a new idea for the synthesis and evaluation of the bifunctional catalysts for water splitting. | Wenjuan Xu Jinfa Chang Yinggang Cheng Hongqi Liu Jifan Li Yongjian Ai Zenan Hu Xinyue Zhang Yiming Wang Qionglin Liang Yang Yang Hongbin Sun | 2022 | Nano Research2022，15，2： | 1 |
