| 1 | The Critical Rainfall Characteristics for Torrents and Debris Flows in the Wenchuan Earthquake Stricken Area显示文摘Critical rainfall assessment is a very important tool for hazard management of torrents and debris flows in mountainous areas. The Wenchuan Earthquake 2008 caused huge casualties and property damages in the earthquake-stricken area,which also generated large quantities of loose solid materials and increased occurrence probabilities of debris flows. There is an urgent need to quantify the critical rainfall distribution in the area so that better hazard management could be planned and if real time rainfall forecast is available,torrent and debris flow early-warning could be issued in advance. This study is based on 49-year observations (1954-2003) of up to 678 torrent and debris flow events. Detailed contour maps of 1 hour and 24 hour critical rainfalls have been generated (Due to the data limitation,there was insufficient 10 minute critical rainfall to make its contour map). Generally,the contour maps from 1 hour and 24 hours have similar patterns. Three zones with low,medium and high critical rainfalls have been identified. The characteristics of the critical rainfall zones are linked with the local vegetation cover and land forms. Further studies and observations are needed to validate the finding and improve the contour maps. | CHEN Ningsheng YANG Chenglin ZHOU Wei HU Guisheng LI Huan David Han | 2009 | Journal of Mountain Science2009，6，4： | 35 |
| 2 | The Inhibitory Effect of Oridonin on the Growth of Fifteen Human Cancer Cell Lines显示文摘OBJECTIVE To study the inhibitory effect of oridonin on the growth of cancer cells. METHODS Fifteen human cancer cell lines were subjected to various concentrations of oridonin in culture medium. The inhibitory rate of cell growth was measured by the MTT assay, and compared with a negative con- trol and 5-Fu-positive control. RESULTS The 50% inhibiting concentration (IC50) and maximal inhibition (Imax) of oridonin shown by studying the growth of the cancer cell lines were as follows: leukemias (HL60 cells: 3.9 μg/ml and 73.8%, K562 cells: 4.3 μg/ml and 76.2%); esophageal cancers(SHEEC cells: 15.4 μg/ml and 99.2%, Eca109 cells: 15.1 μg/ml and 84.6%, TE1 cells: 4.0 μg/ml and 70.2%); gastric cancers (BGC823 cells: 7.6 μg/ml and 98.7%, SGC7901 cells: 12.3 μg/ml and 85.7%); colon cancers (HT29 cells: 13.6 μg/ml and 97.2%, HCT cells: 14.5 μg/ml and 96.5%); liver cancers (Bel7402 cells: 15.2 μg/ml and 89.2%, HepG2 cells: 7.1 μg/ml and 88.3%); pancreatic cancer (PC3 cells: 11.3 μg/ml and 68.4%); lung cancer (A549 cells: 18.6 μg/ml and 98.0% ); breast cancer (MCF7 cells: 18.4 μg/ml and 84.7%); uterine cervix cancer (Hela cells: 13.7 μg/ml and 98.5%). CONCLUSION Oridonin had a relatively wide anti-tumor spectrum, and a relatively strong inhibitory effect on the growth of the 15 human cancer cells. Inhibitory effects were concentration dependent. | Junhui Chen Shaobin Wang Dongyang Chen Guisheng Chang Qingfeng Xin Shoujun Yuan Zhongying Shen | 2007 | Chinese Journal of Clinical Oncology2007，4，1： | 32 |
| 3 | Design of integrated radar and communication system based on MIMO-OFDM waveform显示文摘Orthogonal frequency division multiplexing(OFDM)waveform enables radar and communication functions simultaneously, which encounters low angle resolution and poor data rate for traditional single input single output(SISO) systems. To solve these problems, an integrated radar and communication system(IRCS) with multiple input multiple output(MIMO) OFDM waveform is proposed. The different limitations of radar and communication in designing such a system are investigated. Then, an optimization problem is devised to obtain suitable system parameters, including the number of subcarriers, subcarrier spacing, number of symbols,pulse repetition frequency(PRF) and length of cyclic prefix(CP).Finally, to satisfy the requirements of both radar and communication, the IRCS parameters are derived in three typical cases.Several numerical results are presented to illustrate the demands of radar and communication, inconsistent or consistent, for the IRCS parameters and the superiority of the proposed system. | Yongjun Liu Guisheng Liao Zhiwei Yang Jingwei Xu | 2017 | Journal of Systems Engineering and Electronics2017，28，4： | 16 |
| 4 | Method for array gain and phase uncertainties calibration based on ISM and ESPRIT显示文摘A new method for array calibration of array gain and phase uncertainties, which severely degrade the performance of spatial spectrum estimation, is presented. The method is based on the idea of the instrumental sensors method (ISM), two well-calibrated sensors are added into the original array. By applying the principle of estimation of signal parameters via rotational invariance techniques (ESPRIT), the direction-of-arrivals (DOAs) and uncertainties can be estimated simultaneously through eigen-decomposition. Compared with the conventional ones, this new method has less computational complexity while has higher estimation precision, what’s more, it can overcome the problem of ambiguity. Both theoretical analysis and computer simulations show the effectiveness of the proposed method. | Liao Bin Liao Guisheng | 2009 | Journal of Systems Engineering and Electronics2009，20，2： | 11 |
| 5 | Enhancement of Fenton oxidation for removing organic matter from hypersaline solution by accelerating ferric system with hydroxylamine hydrochloride and benzoquinone显示文摘Fenton oxidation is generally inhibited in the presence of a high concentration of chloride ions.This study investigated the feasibility of using benzoquinone(BQ) and hydroxylamine hydrochloride(HA) as Fenton enhancers for the removal of glycerin from saline water under ambient temperature by accelerating the ferric system.It was found that organics removal was not obviously affected by chloride ions of low concentration(less than 0.1 mol/L),while the mineralization rate was strongly inhibited in the presence of a large amount of chloride ions.In addition,ferric hydrolysis-precipitation was significantly alleviated in the presence of HA and BQ,and HA was more effective in reducing ferric ions into ferrous ions than HA,while the H_2O_2 decomposition rate was higher in the BQ-Fenton system.Electron spin resonance analysis revealed that OH production was reduced in high salinity conditions,while it was enhanced after the addition of HA and BQ(especially HA).This study provided a possible solution to control and alleviate the inhibitory effect of chloride ions on the Fenton process for organics removal. | Siwei Peng Weijun Zhang Jie He Xiaofang Yang Dongsheng Wang Guisheng Zeng | 2016 | Journal of Environmental Sciences2016，28，3： | 10 |
| 6 | Ferroelectric and piezoelectric properties of novel relaxor ferroelectric single crystals PMNT显示文摘Relaxor ferroelectric single crystals PMNT with the size of φ40 mm×80 mm have been grown by a modified Bridgman method and their ferroelectric and piezoelectric properties have been characterized. The properties varied with the compositions and cut types. On the (001) cut, PMNT76/24 single crystals exhibited a dielectric constant ε of about 3 400, a dielectric loss of tanδ <0.7%, a piezoelectric constant d33 of 980 pC/N, an electromechanical coupling factor kt of 0.55 and Tc of about 110℃. whereas the properties of PMNT67/33 single crystals on (001) cut were betler: e of about 5 300, tan5 <0.6%, d33 up to 3 000 pC/N, kt 0.64, K33 0.93 and Tc of about 150℃. The piezoelectric properties on other cuts such as (110) and (111) were much lower than those on the (001) cut. The rhombohedral PMNT crystals grown by this method showed more excellent piezoelectric properties than those grown by high temperature solution method and higher value of kt than the rhombohedral PZNT single crystals. it has also | XU Guisheng LUO Haosu WANG Pingchu XU Haiqing YIN Zhiwen | 2000 | Chinese Science Bulletin2000，45，6： | 10 |
| 7 | An estimation method for InSAR interferometric phase combined with image auto-coregistration显示文摘In this paper we propose a method to estimate the InSAR interferometric phase of the steep terrain based on the terrain model of local plane by using the joint subspace projection technique proposed in our previous paper. The method takes ad- vantage of the coherence information of neighboring pixel pairs to auto-coregister the SAR images and employs the projection of the joint signal subspace onto the corresponding joint noise subspace to estimate the terrain interferometric phase. The method can auto-coregister the SAR images and reduce the interferometric phase noise simultane- ously. Theoretical analysis and computer simulation results show that the method can provide accurate estimate of the interferometric phase (interferogram) of very steep terrain even if the coregistration error reaches one pixel. The effectiveness of the method is veri- fied via simulated data and real data. | LI Hai LI Zhenfang LIAO Guisheng BAO Zheng | 2006 | Science in China(Series F)2006，49，3： | 10 |
| 8 | Necessary and Sufficient Conditions for Consensus in Third Order Multi-Agent Systems显示文摘We deal with a consensus control problem for a group of third order agents which are networked by digraphs.Assuming that the control input of each agent is constructed based on weighted difference between its states and those of its neighbor agents, we aim to propose an algorithm on computing the weighting coefficients in the control input. The problem is reduced to designing Hurwitz polynomials with real or complex coefficients. We show that by using Hurwitz polynomials with complex coefficients, a necessary and sufficient condition can be obtained for designing the consensus algorithm. Since the condition is both necessary and sufficient, we provide a kind of parametrization for all the weighting coefficients achieving consensus. Moreover, the condition is a natural extension to second order consensus, and is reasonable and practical due to its comparatively decreased computation burden. The result is also extended to the case where communication delay exists in the control input. | Chi Huang Guisheng Zhai Gesheng Xu | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，6： | 8 |
| 9 | FAST RECURSIVE LEAST SQUARES LEARNING ALGORITHM FOR PRINCIPAL COMPONENT ANALYSIS显示文摘Based on the least-square minimization a computationally efficient learning algorithm for the Principal Component Analysis(PCA) is derived. The dual learning rate parameters are adaptively introduced to make the proposed algorithm providing the capability of the fast convergence and high accuracy for extracting all the principal components. It is shown that all the information needed for PCA can be completely represented by the unnormalized weight vector which is updated based only on the corresponding neuron input-output product. The convergence performance of the proposed algorithm is briefly analyzed.The relation between Oja’s rule and the least squares learning rule is also established. Finally, a simulation example is given to illustrate the effectiveness of this algorithm for PCA. | Ouyang Shan Bao Zheng Liao Guisheng(Guilin Institute of Electronic Technology, Guilin 541004)(Key Laboratory of Radar Signal Processing, Xidian Univ., Xi’an 710071) | 2000 | Journal of Electronics(China)2000，17，3： | 8 |
| 10 | Efficacy and safety of Yunxiangjing derived from Chinese herbal medicine administered as an enema in the management of acute radiation-induced proctitis in patients with pelvic malignancy显示文摘OBJECTIVE: To assess the efficacy and safety of Yunxiangjing(YXJ), derived from Chinese herbal medicine, in the management of acute radiation-induced proctitis(ARIP) in patients with pelvic malignancy.METHODS: Forty-eight patients with grade 2 ARIP were administered YXJ as an enema(1∶30 dilution)for 2 weeks and followed up for 2 years. All were assessed for response and ARIP grade. Quality of life(QOL) was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30.RESULTS: Of the 48 patients, six(12.5%) achieved complete remission of ARIP and 28(58.3%) showed a decrease from grade 2 to grade 1 ARIP. No patient experienced a grade ≥3 toxicity. At the end of radiotherapy, patients showed significant improvements in QOL(P < 0.05). Two years after treatment, 46 patients showed no late toxicity, with only two experiencing grade 1 late toxicity.CONCLUSION: YXJ can be used as an enema to manage acute radiation-induced proctitis in cancer patients undergoing radiotherapy. These findings suggest that YXJ enema may be an alternative treatment of ARIP. | Tang Huaying Huang Yinchun Mo Xingneng Yi Guisheng Wen Hui Guo Zhen Feng Kaihua Liu Yin Bu Qing Jiang Wei | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 7 |
| 11 | Ultrasound-Assisted Transient Liquid Phase Bonding of Magnesium Alloy Using Brass Interlayer in Air显示文摘The microstructure evolution and oxide film behavior in ultrasound-assisted transient liquid phase(U-TLP) bonding of Mg alloy were investigated by applying different ultrasonic time at 460?C with brass interlayer in air. The results indicated that with increasing ultrasonic time, brass interlayer disappeared gradually and the Mg-Cu-Zn eutectic compounds were formed. The eutectic compounds in the joint decreased as the ultrasonic time increased further. The oxide removal process was divided into four steps. Continuous oxide film at the interface was partially fractured by ultrasonic vibration,and then suspended into liquid by undermining eutectic reaction. After that, the suspended oxide film was broken into small oxide fragments by ultrasonic cavitation effect, which was finally squeezed out of the joint by ultrasonic squeeze action. In addition, the mechanical properties of the joints were investigated. The maximum shear strength of the joint reached 105 MPa, which was 100% of base metal. | Zhiwei Lai Ruishan Xie Chuan Pan Xiaoguang Chen Lei Liu Wenxian Wang Guisheng Zou | 2017 | Journal of Materials Science & Technology2017，33，6： | 7 |
| 12 | Interfacial Structure and Formation Mechanism of Ultrasonic-assisted Brazed Joint of SiC Ceramics with Al—12Si Filler Metals in Air显示文摘Ultrasonic-assisted brazing of SiC ceramics was performed by filling with an Al—12Si alloy at a low temperature of 620 °C in air. The interfacial characteristics and formation mechanism were investigated. The joint shear strength reached 84–94 MPa using the ultrasonic time of 2–16 s. The fracture morphology showed that the fracture path initiated and propagated in the joint alloy. The thin film of amorphous SiO 2 that formed on the SiC surface was non-uniformly decomposed and diffused into the liquid Al—12Si alloy under the cavitation erosion effect of ultrasound. Abnormal isolated blocks of Al_2 SiO_5 compounds formed at the interface between Al—12Si and a thicker SiO_2 layer formed during the thermal oxidation treatment of the Si C ceramic. The SiO_2 layer on the Si C ceramic did not hinder or impair the wetting and bonding process, and a stronger bond could form between Al—12Si and SiO_2 or Si C in ultrasonicassisted brazing. | Xiaoguang Chen Ruishan Xie Zhiwei Lai Lei Liu Jiuchun Yan Guisheng Zou | 2017 | Journal of Materials Science & Technology2017，33，5： | 6 |
| 13 | Applications of high-gravity technologies in gas purifications: A review显示文摘The traditional gas purification techniques such as wet gas desulfurization, with their advantages of large-scale implementation and maturity, have still been widely used. However, the main drawback of these techniques is the low transfer efficiency, which normally needs towers as tall as tens of meters to remove the pollutants. Therefore, new technologies which could enhance the mass transfer efficiency and are less energy-intensive are highly desirable. As a process intensification technology, high-gravity technology, which is carried out in a rotating packed bed(RPB), has recently demonstrated great potential for industrial applications due to its high mass transfer efficiency, energy-saving, and smaller volume. This consequently provides higher efficiency in toxic gas removal, and can significantly reduce the investment and operation costs. In this review, the mechanism,characteristics, recent developments, and the industry applications of high-gravity technologies in gas purifications, such as hydrogen sulfide, nitrogen oxide, carbon dioxide, sulfur dioxide, volatile organic compounds and nanoparticle removal are discussed, most of the demonstration projects and practical application examples in gas purification come from China. The perspective and prospective of this technology in gas purification and other fields are also briefly discussed. | Jing Guo Weizhou Jiao Guisheng Qi Zhiguo Yuan Youzhi Liu | 2019 | Chinese Journal of Chemical Engineering2019，27，6： | 5 |
| 14 | Analysis of Hot Topics in Cloud Computing显示文摘In the field of cloud computing, topics such as computing resource virtualization, differences between grid and cloud computing, relationship between high-performance computers and cloud computing centers, and cloud security and standards have attracted much research interest. This paper analyzes these topics and highlights that resource virtualization allows information services to be scalable, intensive, and specialized; grid computing involves using many computers for large-scale computing tasks, while cloud computing uses one platform for multiple services; high-performance computers may not be suitable for a cloud computing; security in cloud computing focuses on trust management between service suppliers and users; and based on the existing standards, standardization of cloud computing should focus on interoperability between services. | Li Deyi Chen Guisheng Zhang Haisu | 2010 | ZTE Communications2010，8，4： | 5 |
| 15 | Study on Industrial Application of Hydrogen Sulfide Removal by Wet Oxidation Method with High Gravity Technology显示文摘The removal of hydrogen sulfide from gas plays an important role in rational utilization of resources and environ- mental protection. In this paper, the process of hydrogen sulfide removal by wet oxidation method in a rotating packed bed was investigated in a scale for treating 10 000 Nm3/h of gas. On the basis of studying the influence of the species and con- centration of alkali source, the liquid/gas volume ratio, the high gravity factor, and the hydrogen sulfide content in feed gas on the desulfurization effect, the suitable technological conditions were obtained. The hydrogen sulfide removal efficiency could reach 98.0% under these conditions. The results of continuous operation of process facilities showed that the high gravity method has many merits including higher desulfurization rate, good stability in operation, lower liquid/gas volume ratio, greater operation elasticity, and apparent energy saving effects. | Qi Guisheng Liu Youzhi Jiao Weizhou (Research Center of Shanxi Province for High Gravity Chemical Engineering and Technology, North University of China, Taiyuan 030051) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，4： | 5 |

| 17 | Photoelectrocatalytic reduction of CO_2 to methanol over a photosystem Ⅱ-enhanced Cu foam/Si-nanowire system显示文摘A solar-light double illumination photoelectrocatalytic cell(SLDIPEC) was fabricated for autonomous CO_2 reduction and O_2 evolution with the aid of photosystem II(PS-II, an efficient light-driven water-oxidized enzyme from nature) and utilized in a photoanode solution. The proposed SLPEC system was composed of Cu foam as the photoanode and p-Si nanowires(Si-NW) as the photocathode. Under solar irradiation, it exhibited a super-photoelectrocatalytic performance for CO_2 conversion to methanol, with a high evolution rate(41.94 mmol/hr), owing to fast electron transfer from PS-II to Cu foam.Electrons were subsequently trapped by Si-NW through an external circuit via bias voltage(0.5 V), and a suitable conduction band potential of Si(-0.6 e V) allowed CO_2 to be easily reduced to CH_3 OH at the photocathode. The constructed Z-scheme between Cu foam and Si-NW can allow the SLDIPEC system to reduce CO_2(8.03 mmol/hr) in the absence of bias voltage. This approach makes full use of the energy band mismatch of the photoanode and photocathode to design a highly efficient device for solving environmental issues and producing clean energy. | Zichao Lian Donglai Pan Wenchao Wang Dieqing Zhang Guisheng Li Hexing Li | 2017 | Journal of Environmental Sciences2017，29，10： | 5 |
| 18 | FAST MUSIC SPECTRUM PEAK SEARCH VIA METROPOLIS-HASTINGS SAMPLER显示文摘A fast MUltiple SIgnal Classification (MUSIC) spectrum peak search algorithm is devised, which regards the power of the MUSIC spectrum function as target distribution up to a constant of proportionality, and uses Metropolis-Hastings (MH) sampler, one of the most popular Markov Chain Monte Carlo (MCMC) techniques, to sample from it. The proposed method reduces greatly the tremendous computation and storage costs in conventional MUSIC techniques i.e., about two and four orders of magnitude in computation and storage costs under the conditions of the experiment in the paper respectively. | Guo Qinghua Liao Guisheng | 2005 | Journal of Electronics(China)2005，22，6： | 5 |
| 19 | Mass transfer characteristics in a rotating packed bed with split packing显示文摘The rotating packed bed(RPB) with split packing is a novel gas–liquid contactor, which intensifies the mass transfer processes controlled by gas-side resistance. To assess its efficacy, the mass transfer characteristics with adjacent rings in counter-rotation and co-rotation modes in a split packing RPB were studied experimentally.The physical absorption system NH3–H2O was used for characterizing the gas volumetric mass transfer coefficient(kyae) and the effective interfacial area(ae) was determined by chemical absorption in the CO2–NaO H system. The variation in kyaeand aewith the operating conditions is also investigated. The experimental results indicated that kyaeand aefor counter-rotation of the adjacent packing rings in the split packing RPB were higher than those for co-rotation, and both counter-rotation and co-rotation of the split packing RPB were superior over conventional RPBs under the similar operating conditions. | Youzhi Liu Deyin Gu Chengcheng Xu Guisheng Qi Weizhou Jiao | 2015 | Chinese Journal of Chemical Engineering2015，23，5： | 4 |
| 20 | Selection of Chelated Fe(Ⅲ)/Fe(Ⅱ) Catalytic Oxidation Agents for Desulfurization Based on Iron Complexation Method显示文摘Optimization of factors influencing the experiments on reactions involving 8 different chelating agents and soluble Fe(III)/Fe(II) salts was carried out to yield chelated iron complexes. A combination of optimized influencing factors has resulted in a Fe chelating capacity of the iron-based desulfurization solution to be equal to 6.83—13.56 g/L at a redox potential of 0.185—0.3. The desulfurization performance of Fe(III)/Fe(II) chelating agents was investigated on a simulated sulfur-containing industrial gas composed of H2 S and N2 in a cross-flow rotating packed bed. Test results have revealed that the proposed iron-based desulfurization solution showed a sulfur removal efficiency of over 99% along with a Fe chelating capacity exceeding 1.35 g/L. This desulfurization technology which has practical application prospect is currently in the phase of commercial scale-up study. | Luo Ying Liu Youzhi Qi Guisheng Guo Huidong Zhu Zhengfeng | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，2： | 4 |
