| 2 | Application of a microseismic monitoring system in deep mining显示文摘A microseismic monitoring system was used in the Donggua Shan underground copper mine, and its application was intro- duced. The spacial distribution of the seismic event was monitored effectively during mining with this system. The distribution of the seismic intensity in different time periods and in the different mining districts was obtained via the clustering analysis of the monitored results, and the different intensity concentration districts of seismicity were compartmentalized. The various characteristics and wave- forms of different vibrations in the underground mine were revealed with the help of the micro-seismic monitoring system. It was proved that the construction and application of the micro-seismic monitoring system in the mine not only realized the continuous monitoring of seismicity in the deep mine, but also settled an important foundation for further studies on hazard prediction, based on this system. | Chengxiang Yang Zhouquan Luo Guobin Hu Xiaoming Liu | 2007 | Journal of University of Science and Technology Beijing2007，14，1： | 14 |
| 3 | First observations of low latitude whistlers using WHU ELF/VLF receiver system显示文摘The recently developed high-quality WHU ELF/VLF receiver system has been deployed in Suizhou, China(geomagnetic latitude 21.81°N, longitude 174.44°E, L=1.16) to detect low latitude extremely-low-frequency(ELF: 0.3-3 k Hz) and very-low-frequency(VLF: 3-30 k Hz) emissions originating from either natural or artificial sources since February 2016. During the first-month operation of the receiver system, a total of 3039 clear whistlers have been recorded at this low latitude station with the majority(97.0%) occurring on 28 February and 1 March 2016. Observed whistlers manifest various types including single one-hop, echo train, multi-flash, and multi-path. They tend to intensify after local midnight, reach the peak around 04-05 LT, and then weaken quickly. Both features of lower cutoff frequencies of most whistlers below ~1.6 k Hz and almost uniform dispersion for many successive multi-flash whistlers suggest that these whistlers propagate along the geomagnetic field lines in the duct mode. The computed dispersion varies between ~15 s^(1/2) and 23 s^(1/2) for observed one-hop whistlers and is greater than 50 s^(1/2) for three-hop echo train whistlers, indicating that the whistlers observed at the Suizhou station are low latitude whistlers. | CHEN YanPing NI BinBin GU XuDong ZHAO ZhengYu YANG GuoBin ZHOU Chen ZHANG YuanNong | 2017 | Science China(Technological Sciences)2017，60，1： | 12 |

| 5 | Analysis of Comprehensive Benefits of Transforming Slope Farmland to Terraces on the Loess Plateau:A Case Study of the Yangou Watershed in Northern Shaanxi Province,China显示文摘De-farming slope farmland has been an effective measure in recent years to improve environment and prevent soil and water loss on the Loess Plateau.There are different views about the defarming method,and also various de-farming patterns have been put into practice.This paper takes the Yangou Watershed in Shaanxi Province of China as a case for studying the comprehensive benefits of transforming slope farmland to terraces.Based on the day-by-day meteorological data of the Yan'an station in 2005 and the data of terrain features,soil and land use data of the Yangou Watershed,the impact of transforming slope farmland on terraces were simulated and analyzed in aspects of yield increase and water-soil conservation under different topographic conditions with the aid of software WIN-YIELD.Furthermore,an empirical analysis was applied to study the effects of transforming slope farmland to terraces in the Yangou Watershed.The results show that:(1) The bigger the topographic gradient is,the more remarkable benefits it has in yield increase and water-soil conservation.(2) Farmland with slope below 5° could be retained,but farmland with slope above 15° should be converted to forest or grassland as soon as possible.(3) Transforming slope farmland to terraces has the same remarkable effects as the current policy of 'Relieving and de-farming' in improving agricultural production conditions,safeguarding food security,raising permanent vegetation coverage rate,and preventing soil and water loss.Besides,it is more cost-effective than the policy of 'Relieving and de-farming'.It's strongly suggested that the policy of transforming slope farmland to terraces be carried out on the Loess Plateau without delay. | XU Yong YANG Bo TANG Qing LIU Guobin LIU Puling | 2011 | Journal of Mountain Science2011，8，3： | 8 |
| 6 | Application of the oblique ionogram as vertical ionogram显示文摘The vertical ionogram can provide the important ionospheric parameters, such as critical frequency, virtual height and electron density, for ionospheric research. The oblique ionosonde has the ability to detect the ionosphere over sea and other terrain where it is not practical to deploy vertical sounder and provide more ionograms with less transmitting and receiving devices. Therefore, the conversion of the oblique ionogram to vertical ionogram for obtaining the important ionospheric parameters is a very useful inversion technology. The experimental comparison between oblique and vertical detections was carried out in the equatorial ionospheric anomaly (EIA) region of south China on 25 and 26 August 2010. The oblique detecting path was from Wuhan to Shenzhen and the VI ionosonde was located in the midpoint of the oblique path. The oblique ionogram reversion results showed a small deviation of the critical frequency, minimum virtual height as well as the electron density profile of the ionospheric F layer, as compared with the real vertical observations. | CHEN Gang ZHAO ZhengYu ZHANG YuanNong YANG GuoBin ZHOU Chen HUANG Shuo LI Ting LI Ning SUN HengQing | 2012 | Science China(Technological Sciences)2012，55，5： | 5 |
| 7 | Molecular dynamics simulation on diffusion properties of Pb-Mg alloy显示文摘A new method to calculate mutual-diffusion coefficients of the binary alloy has been proposed in this report.At first self-diffusion coefficient of the constituent element was calculated using molecular dynamics method,thermodynamic factor of the alloy was got with the NRTL (non-random-two-liquid) equation,then mutual-diffusion coefficient was obtained with Darken formula.Using this method the mutual-diffusion coefficient of Pb-Mg alloy with different Pb content was calculated.The calculated values were compared with the available experimental ones and the reason of the maximal mutual-diffusion coefficient appearing at 33.3 at.%Pb was discussed.Partial pair correlation function and partial coordination number were calculated to analyze the effect of the melt structure on mutual-diffusion coefficient. | LIU YuanYuan,JIA GuoBin & YANG Bin National Engineering Laboratory of Vacuum Metallurgy,Kunming University of Science and Technology,Kunming 650093,China | 2010 | Science China(Technological Sciences)2010，53，9： | 3 |
| 8 | Diagnostic value of negative enrichment and immune fluorescence in situ hybridization for intraperitoneal free cancer cells of gastric cancer显示文摘Objective:To explore the intraperitoneal free cancer cell(IFCC)detection value of negative enrichment and immune fluorescence in situ hybridization(NEimFISH)on chromosomes(CEN)8/17.Methods:To verify the reliability of NEimFISH,29 gastric cancer tumors,their adjacent tissues and greater omental tissues were tested.Our study then included 105 gastric cancer patients for IFCC.We defined patients as IFCC-positive if a signal was detected,regardless of the detailed cancer cell numbers.A comparison of clinicopathological features was conducted among IFCC groups.We also compared the diagnosis value and peritoneal recurrence predictive value among different detection methods.The comparison of IFCC number was also conducted among different groups.Results:A cutoff of 2.5 positive cells could distinguish all benign tissue samples and 97%of malignant tissue samples in our study.Compared to intestinal gastric cancer,patients with diffuse gastric cancer tended to have more IFCCs(6 vs.4,P=0.002).The IFCC counts were often higher in the lymphovascular invasion positive group than negative group(3 vs.1,P=0.022).All IFCC samples that were considered positive using conventional cytology were also found to be positive using NEimFISH.When compared to conventional cytology and paraffin pathology,NEimFISH had a higher IFCC positive rate(68.9%)and higher one-year peritoneal recurrence predictive value with area under the curve(AUC)of 0.922.Conclusions:Gastric cancer could be effectively diagnosed by NEimFISH.The IFCC number found using NEimFISH on CEN8/17 is closely associated with Lauren type and vascular invasion of cancer.NEimFISH is a reliable detection modality with a higher positive detection rate,higher one-year peritoneal recurrence predictive value and quantitative features for IFCC of gastric cancer. | Anqiang Wang Zhongwu Li Qian Wang Yali Bai Xin Ji Tao Fu Ke Ji Yanwen Xue Tingxu Han Xiaojiang Wu Ji Zhang Yingjie Yang Guobin Xu Zhaode Bu Jiafu Ji | 2019 | Chinese Journal of Cancer Research2019，31，6： | 3 |
| 9 | Numerical simulation of the propagation of electromagnetic waves in ionospheric irregularities显示文摘The characteristics of high-frequency(HF)electromagnetic(EM)wave propagation can be affected when EM waves propagate in the ionosphere.When ionospheric irregularities appear in the ionosphere,they can have a serious impact on the propagation of HF EM waves.In this study,the propagation of HF EM waves in ionospheric irregularities was investigated by numerical simulation.First,a twodimensional model of plasma bubbles was used to produce ionospheric irregularities in the ionosphere.A ray-tracing method was then utilized to simulate the propagation of HF radio waves in these ionospheric irregularities.Results showed that the propagation of HF radio waves in the ionosphere was more complex in ionospheric irregularities than without ionospheric irregularities.In addition,corresponding ionograms were synthesized by radio rays propagated in the ionosphere with these irregularities.The synthesized ionograms were then compared with the experimental ionograms recorded by an ionosonde.Results showed that spread F could be simulated on the ionograms when ionospheric irregularities occurred in the ionosphere.This result was consistent with the ionosonde observations. | Chun Hua Jiang LeHui Wei GuoBin Yang Chen Zhou ZhengYu Zhao | 2020 | Earth and Planetary Physics2020，4，6： | 3 |
| 10 | Design and Implementation of Hardware Architecture in Ionospheric Oblique Backscattering Sounding System显示文摘The ionospheric oblique backscattering sounding sys-tem can not only be used to detect the state of the ionosphere and the condition of high frequency channel in real time, but also be used for over-the-horizon sounding. Therefore, it has a very high military and civil value. For the characteristics of ionospheric oblique backscattering sounding, such as long sounding distance, wake echo, strong background noise, slow moving target, etc., a hardware platform of ionospheric oblique backscattering sounding system is designed. This platform adopts the technology of soft-ware radio and is designed as a new kind of general purpose, modularized, software-based ionosonde that is based on the VXI (Versa module eurocard eXtensions for Instrumentation) bus. This hardware platform has been successfully used in actual iono-spheric oblique backscattering sounding, and the experimental results demonstrate that this system can satisfy the requirements. | SHI Shuzhu ZHAO Zhengyu YANG Guobin ZHANG Yuannong LIU Ruiyuan | 2009 | Wuhan University Journal of Natural Sciences2009，14，1： | 3 |
| 11 | Molecular cloning and expression patterns of the cholesterol side chain cleavage enzyme(CYP11A1) gene during the reproductive cycle in goose(Anas cygnoides)显示文摘Background: CYP11A1, a gene belonging to the family 11 of cytochrome P450, encodes a crucial steroidogenic enzyme that catalyzes the initial step in the production of all classes of steroids. Many studies show that CYP11A1 plays a role in ovary function. However, the role of CYP11A1 in goose reproductive cycle remains largely unknown.Results: In this study, full-length CYP11A1 c DNA of Zhedong goose was obtained using reverse transcription polymerase chain reaction(RT-PCR) and rapid amplification of c DNA ends(RACE). The c DNA consisted of a 96-base pair(bp) 5′untranslated region(UTR), a 179-bp 3′UTR and a 1509-bp open reading frame. The open reading frame encodes a putative 503 amino acid protein that shares high homology with CYP11A1 of other birds. The amino acid sequence possesses conserved domains of the P450 superfamily, which include the steroid-binding domain and the heme-binding region. Real-time quantitative polymerase chain reaction(q PCR) analysis revealed CYP11A1 mR NA was expressed ubiquitously in every Zhedong goose tissue analyzed, including the heart, liver, glandular stomach,lung, spleen, kidney, intestinum tenue, intestinum crassum, cerebrum, cerebellum, muscle, oviduct, pituitary,hypothalamus and ovary.. The relatively low levels of CYP11A1 m RNA were detected in pituitary, ovary and oviduct tissues at ovulation when compared with levels at oviposition. Interestingly, higher expression was observed in ovary and oviduct tissues during brooding. Lastly, higher m RNA expression of Yangzhou geese was detected during the ovulation period than that of Zhedong geese.Conclusions: Our findings reveal the sequence characterization and expression patterns of the CYP11A1 gene during the goose reproductive cycle, which may provides correlative evidence that CYP11A1 expression is important in reproduction activity. | Qi Xu Yadong Song Yang Chen Ran Liu Yang Zhang Yang Li Zhengyang Huang Wenming Zhao Guobin Chang Guohong Chen | 2016 | Journal of Animal Science and Biotechnology2016，7，2： | 2 |

| 13 | Correlation between the physical parameters and the electrochemical performance of a silicon anode in lithium-ion batteries显示文摘Lithium-ion battery anode used as silicon particles were obtained from different major suppliers,and they were characterized by different spectroscopic techniques and evaluated by electrochemical experiments.Correlations between the key physical parameters and electrochemical properties of the silicon particles were investigated.Silicon particle size,surface oxygen content,-OH content and physical appearance are found to strongly influence the electrochemical properties of the Si anode.The particle size of 100 nm has great promise for the practical application of Si nanoparticles in the lithium-ion battery industry.An inverse correlation between the oxygen content and the reversible capacity or first coulombic efficiency was obtained.The-OH content by surface treatment contributes to enhanced cycling stability by the improved affinity between the Si particle and the water-soluble binder.Spherical Si particles perform better compared to irregular particles,and agglomeration dramatically decreases the cycling stability of the Si anode.Among the investigated Si particles,the sample that exhibited a reversible capacity of more than 2500 mAh g^(-1),a first coulombic efficiency of 89.26%and an excellent cycling stability,has great potential for use in the battery industry. | Guobin Zhu Yan Wang Siming Yang Qunting Qu Honghe Zheng | 2019 | Journal of Materiomics2019，5，2： | 2 |
| 14 | Eff ect of Cementation on Calcium Carbonate Precipitation of Loose Sand Resulting from Microbial Treatment显示文摘Microbe-induced calcite precipitation is a sustainable improvement technique for sandy soil, which can alter the properties of sand via microbial activity. In this study, we investigated the loose-sand-consolidation eff ect by controlling the injection velocity, bacterial and cementingsolution concentrations, and hold times. The results demonstrate that, as the cyclic batch increases, the utilization rate of the bacterial fl uid increases and both the optical density(OD_(600)) of the bacteria and urease activity decrease. Moreover, it was determined that a 3-h hold time for a 0.5 mol/L cementing solution with a cementing fl uid velocity of 2 mL/min has the greatest bonding eff ect. The fi nal strength of the loose sand with an increase in calcium carbonate content was further discussed. | Yang Tang Jijian Lian Guobin Xu Yue Yan Hongyin Xu | 2017 | Transactions of Tianjin University2017，23，6： | 2 |
| 15 | The analysis of genetic diversity and differentiation of six Chinese cattle populations using microsatellite markers显示文摘A total of 321 individuals from six cattle populations of four species in a bovine subfamily in China were studied using 12 pairs of mi- crosatellite markers. The genetic diversities within and between populations were calculated. The phylogenetic trees were constructed by (δμ) 2 and DA distances, and the divergence times between populations were estimated by (δμ) 2. Altogether, 144 microsatellite alleles were detected including 24 private alleles and nine shared alleles. Chinese Holstein had the largest number of private alleles (10), whereas, Bohai black and Buffalo had the smallest number of private alleles (2). Chinese Holstein showed the highest genetic variability. Its ob- served number of alleles (Na), mean effective number of alleles (MNA), and mean heterozygosity (He) were 7.7500, 4.9722, and 0.7719, respectively, whereas, the Buffalo and Yak showed low genetic variability. In the phylogenetic trees, Luxi and Holstein grouped first, followed by Bohai and Minnan. Yak branched next and buffalo emerged as the most divergent population from other cattle populations. Luxi and Bohai were estimated to have diverged 0.039-0.105 million years ago (MYA), however, buffalo and Holstein diverged 0.501-1.337 MYA. The divergence time of Yak versus Minnan, Holstein and buffalo was 0.136-0.363, 0.273-0.729, and 0.326-0.600 MYA, respectively. | Yongjiang Mao Hong Chang Zhangping Yang Liu Zhang Ming Xu Guobin Chang Wei Sun Guangming Song Dejun Ji | 2008 | Journal of Genetics and Genomics2008，35，1： | 2 |
| 16 | Doppler estimating and compensating method based on phase显示文摘According to the Doppler sensitive of the phase coded pulse compression signal,a Doppler estimating and compensating method based on phase is put forward to restrain the Doppler sidelobes,raise the signal-to-noise ratio and improve measuring resolution.The compensation method is used to decompose the echo to amplitude and phase,and then compose the new compensated echo by the amplitude and the nonlinear component of the phase. Furthermore the linear component of the phase can be used to estimate the Doppler frequency shift.The computer simulation and the real data processing show that the method has accurately estimated the Doppler frequency shift, successfully restrained the energy leakage on spectrum,greatly increased the echo signal-to-noise ratio and improved the detection performance of the radio system in both time domain and frequency domain. | Chen Gang Zhao Zhengyu Nie Xuedong Shi Shuzhu Yang Guobin Su Fanfan | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 2 |
| 17 | Operational Reliability Model of Hybrid MMC Considering Multiple Time Scales and Multi-state Submodule显示文摘Environmental and electrical factors such as wind speed,air temperature and switching frequency have significant influences on the operational reliability of hybrid modular multilevel converter(MMC),which is commonly used for the wind power transmission.However,the existing reliability model of hybrid MMC based on statistics cannot accurately reflect the impact of these factors.In this paper,a new operational reliability model of hybrid MMC is presented.The reliability index of the hybrid MMC is coupled with its operation characteristics by calculating multi-term thermal cycling.In addition,an operation strategy of hybrid MMC is proposed to improve its reliability.The multi-state submodule(SM)is developed,which is capable of bypassing specific faulty power modules instead of the whole SM.Case studies show that the proposed operational reliability model could describe the impact of environmental and electrical factors.Also,the proposed operation strategy can improve the reliability of hybrid IMMC by extending the operation time of SMs. | Fei Feng Juan Yu Wei Dai Zhifang Yang Xingpan Zhao Salah Kamel Guobin Fu | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，3： | 1 |
| 18 | An anti-freezing biomineral hydrogel of high strain sensitivity for artificial skin applications显示文摘Mineral hydrogels have caught a lot of attention for their strong competency as artificial skin-like materials.Nonetheless,it remains a great difficulty in fulfilling in one hydrogel system a range of key functionalities that are needed for practical artificial skin applications,i.e.,to be biocompatible,strain-sensitive,ion-conductive,elastic and robust,anti-swelling,and anti-freezing.Here we present a such type of versatile hydrogel that is not only capable to deliver all the above-mentioned key functionalities but also highly stable.This novel hydrogel is constructed by introducing a gelatinous and amorphous multi-ionic biomineral(denoted as Mg-ACCP,containing Mg^(2+),Ca^(2+),CO_(3)^(2−),and PO_(4)^(3−))into the network of biocompatible polyvinyl alcohol(PVA)and sodium alginate(SA).The presence of Mg^(2+)and PO_(4)^(3−)in this hydrogel helps prohibit the crystallization of the biominerals,leading to significantly improved stability.The hydrogel thus obtained delivers excellent mechanical performance due to the chelation between the mineral ions and the organic matrix,and high sensitivity even to subtle pressure and strain applied,such as slight finger bending and gentle tapping.Furthermore,the novel hydrogel features high ionic conductivity,high resistance to swelling,and extraordinary anti-freezing property,holding great promise for applications in different practical scenarios,particularly in aqueous or cold environments. | Junda Shen Peng Du Binbin Zhou Guobin Zhang Xinxue Tang Jie Pan Bo Li Jingyang Zhang Jian Lu Yang Yang Li | 2022 | Nano Research2022，15，7： | 1 |
