| 2 | Suppression of Surface Burn in Grinding of Titanium Alloy TC4 Using a Self-inhaling Internal Cooling Wheel显示文摘Based on analysis of surface average temperature and burn degree, this article obtains the threshold temperature of surface burn in grinding titanium alloy with cup wheels. Meanwhile, the impact of the burn degree on the metallographic structure of workpiece surface and metallurgical phase transformations is investigated. In order to reduce the grinding temperature and improve the grinding efficiency, a self-inhaling structure cup segmented wheel is developed to generate internal cooling effect. The internal cooling technology is compared with traditional cooling conditions in the grinding experiments on TC4 (Ti-6Al-4V). The results indicate that the self-inhaling internal cooling wheel can reduce the grinding surface temperature by 30% or more, and the grinding efficiency doubles. Utilizing water-based semi-synthetic coolant, the segmented wheel with the self-inhaling structure can further reduce the grinding temperature by about 50%. | LI Xun CHEN Zhitong CHEN Wuyi | 2011 | Chinese Journal of Aeronautics2011，24，1： | 18 |
| 3 | Influence of high-fluorine environmental background on crops and human health in hot spring-type fluorosis-diseased areas显示文摘Drinking water-type fluorosis is the most harmful endemic disease in China with the largest number of sufferers. Although the implementation of the policy to alter water sources to lower fluoride level has effectively controlled the spread of this kind of endemic disease,its prevalence could not thoroughly be stopped because the high-fluoride environmental background in these endemically diseased areas could still do harm to human health through food chain. Therefore,it is necessary to conduct a more deep-going study on the drinking water-type fluoro-sis. To investigate the effect of high fluorine environmental background on crops and human health in the hot spring-type fluorosis-diseased areas,local water,paddy soil,rice,whole vegetables and soils around their roots were sampled for analysis. The results were compared with those of the control groups in fluorosis-free areas which are similar to the fluorosis-diseased areas both in natural background and in social background. It is indicated that rice and vegetables can accumulate water-soluble fluorine either in soils or in irrigating water,and different crops have different abilities of fixing fluorine. The contents of fluorine in different parts of vegetables in the fluorosis-diseased and fluorosis-free areas were statistically categorized. The results showed that the fluorine contents of roots,tubers,leaves and flowers of vegetables in the fluorosis-diseased areas are 3.56,1.17,3.07 and 3.23 mg/kg,respectively. However,comparisons showed that in the fluorosis-free areas,the fluorine contents are 2.17,0.70,1.91 and 2.52 mg/kg,respectively. Moreover,different parts of a crop also show significantly different fluorine fixation abilities. It is demonstrated that the fluorine contents of the strongly metabolic parts are relatively high. For example,the fluo-rine contents of roots,leaves and flowers of vegetables are much higher than those of stems. The fluorine fixation ability of seeds is very weak. In order to reduce the risk of human body’s exposure to fluoride,the impact of hot spring water on the capability of crops to fix fluorine should be reduced as much as possible. It is of great importance to prevent crops from being irrigated with hot spring water and it is advisable to grow crops with relatively low ca-pabilities to enrich fluorine,such as those with seeds or tubers as the main edible parts in the areas which are se-verely affected by hot spring water. | LAN De WU Daishe LI Ping WANG Tengsheng CHEN Chengguang WANG Wuyi | 2008 | Chinese Journal Of Geochemistry2008，27，4： | 10 |
| 4 | Microsurgical resection of tumors lateroventral and ventral to the high cervical spinal cord显示文摘Background Since there are a complex anatomic structure and vital function in the high cervical spinal cord, it is difficult to remove the tumors lateroventral and ventral to the high cervical spinal cord. This clinical study was undertaken to analyze surgical approaches, manner of tumor resection and postoperative management. Methods Thirty-four patients underwent microsurgical excision of tumors lateroventral and ventral to the high cervical spinal cord by means of three approaches. The tumors comprised mostly Schwannoma and meningioma (88.24%, 30/34) in this group. Tumor volume varied from 3.0 cm×2.5 cm×2.0 cm to 12 cm×3.0 cm×2.5 cm. Of the 34 patients, 4 had dumbbell-shaped tumors growing outside the spinal canal and 7 tumors growing into the intracranium. Results The tumor was totally removed in 32 patients (94.1%). Follow-up for 7 months to 6.4 years (median 3.6 years) showed a recovery of a normal life or work ability in 30 (83.3%) patients. Conclusion Modified operative approaches and microsurgical techniques can raise the rate of total tumor removal and reduce the disability of patients. | LEIPeng WUYi LIZhi-yun WANGYu | 2005 | Chinese Medical Journal2005，，10： | 8 |

| 6 | Numerical simulation to determine the gas explosion risk in longwall goaf areas:A case study of Xutuan Colliery显示文摘Underground gassy longwall mining goafs may suffer potential gas explosions during the mining process because of the irregularity of gas emissions in the goaf and poor ventilation of the working face,which are risks difficult to control.In this work,the 3235 working face of the Xutuan Colliery in Suzhou City,China,was researched as a case study.The effects of air quantity and gas emission on the three-dimensional distribution of oxygen and methane concentration in the longwall goaf were studied.Based on the revised Coward’s triangle and linear coupling region formula,the coupled methane-oxygen explosive hazard zones(CEHZs)were drawn.Furthermore,a simple practical index was proposed to quantitatively determine the gas explosion risk in the longwall goaf.The results showed that the CEHZs mainly focus on the intake side where the risk of gas explosion is greatest.The CEHZ is reduced with increasing air quantity.Moreover,the higher the gas emission,the larger the CEHZ,which moves towards the intake side at low goaf heights and shifts to the deeper parts of the goaf at high heights.In addition,the risk of gas explosion is reduced as air quantities increase,but when gas emissions increase to a higher level(greater than 50 m3/min),the volume of the CEHZ does not decrease with the increase of air quantity,and the risk of gas explosion no longer shows a linear downward trend.This study is of significance as it seeks to reduce gas explosion accidents and improve mine production safety. | Yunzhuo Li Hetao Su Huaijun Ji Wuyi Cheng | 2020 | International Journal of Mining Science and Technology2020，30，6： | 7 |
| 7 | Environmental behaviors of selenium in soil of typical selenosis area,China显示文摘Daba Mountain area is one of the two endemic selenosis areas in China,which may relate with the environmental behaviors of selenium (Se) in soil.This study focuses on the concentraion and distribution of Se and its relationships with some other elements in natural soil in the area.The average concentration of Se in Daba Mountain soils was 14.3 times higher than the value cited for natural soil background worldwide,suggesting that soils in the region were contaminated by the element.The finding was confir... | LI Yonghua WANG Wuyi LUO Kunli | 2008 | Journal of Environmental Sciences2008，20，7： | 7 |
| 8 | Tool Positioning Algorithm Based on Smooth Tool Paths for 5-axis Machining of Sculptured Surfaces显示文摘The current research of the 5-axis tool positioning algorithm mainly focuses on searching the local optimal tool position without gouging and interference at a cutter contact(CC) point,while not considering the smoothness and continuity of a whole tool path.When the surface curvature varies significantly,a local abrupt change of tool paths will happen.The abrupt change has a great influence on surface machining quality.In order to keep generated tool paths smooth and continuous,a five-axis tool positioning algorithm based on smooth tool paths is presented.Firstly,the inclination angle,the tilt angle and offset distance of the tool at a CC point are used as design variables,and the machining strip width is used as an objective function,an optimization model of a local tool positioning algorithm is thus established.Then,a vector equation of tool path is derived by using the above optimization model.By analyzing the equation,the main factors affecting the tool path quality are obtained.Finally,a new tool position optimization model is established,and the detailed process of tool position optimization is also given.An experiment is conducted to machine an aircraft turbine blade by using the proposed algorithm on a 5-axis blade grinding machine,and the machined blade surface is measured with a coordinate measuring machine(CMM).Experimental and measured results show that the proposed algorithm can ensure tool paths are smooth and continuous,improve the tool path quality,avoid the local abrupt change of tool paths,and enhance machining quality and machining efficiency of sculptured surfaces. | XU Rufeng CHEN Zhitong CHEN Wuyi | 2011 | Chinese Journal of Mechanical Engineering2011，24，5： | 7 |
| 9 | 在珠宝首饰界准确鉴定宝石的重要性显示文摘在当今珠宝首饰市场上,无论是优化处理的还是合成的宝石材料,其种类和数量都在增加。在某些情况下,它们呈现出与贵重天然宝石极其相似的外观特征。尽管某些经处理的或合成的宝石材料常显示出其独特的宝石学性质,但对于珠宝商,尤其是对那些缺乏宝石学专业培训或刚刚入门使用常规宝石鉴定方法或设备的珠宝商,鉴定起来十分困难。因此,到专业宝石鉴定实验室去鉴定宝石样品就显得非常必要。在专业实验室中,先进的科学仪器必须由受过培训的专业人员操作。宝石的准确鉴定对维护天然宝石的商业价值及消费者的信心都至关重要。目前大多数宝石学研究的目的是给珠宝首饰商及宝石学家提供可操作的宝石鉴定手段,以有助于确保国际宝石市场的完整性。介绍了几种优化处理及合成宝石材料的鉴定实例,这些材料对当今的宝石鉴定提出了挑战。 | James E.Shigley Taijin Lu Wuyi Wang 张辉 | 2004 | 宝石和宝石学杂志2004，6，2： | 7 |
| 10 | Particle Removal Mechanism of High Volume Fraction SiCp/Al Composites by Single Diamond Grit Tool显示文摘Particle removal mechanism was presented during machining particle SiC/Al composites with diamond grinding tool. The relevant removal modes and their mechanisms were discussed considering the impact and squeezing effect of diamond grit on the SiC particle. The experimental results show that the aluminum matrix has larger plastic deformation, so the aluminum mixed with the surplus SiC particles is cut from the surface. The SiC particles can be removed in multiple ways, such as broken/fractured, micro cracks, shearing and pulled out, etc. More particles removed by shearing, and less particles removed by fractured during material removal progress can produce a better machined surface. | 都金光 MING Wuyi CAO Yang MA Jun 何文斌 LI Xiaoke | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，2： | 6 |
| 11 | Structural bionic design for high-speed machine tool working table based on distribution rules of leaf veins显示文摘High-speed machine tool working table restrains the machining accuracy and machining efficiency,so lightweight design of the table is an important issue.In nature,leaf has developed a plate structure that maximizes the surface-to-volume ratio.It can be seen as a plate structure stiffened by veins.Compared with a high-speed machine tool working table,leaf veins play a role of supporting part which is similar to that of stiffening ribs,and they can provide some new design ideas for lightweight design of the table.In this paper,distribution rules of leaf veins were investigated,and a structural bionic design for the table was achieved based on regulation of leaf veins.First,statistical analysis on geometric structure of leaf veins was carried out,and four distribution rules were obtained.Then,relevant mechanical models were developed and analyzed in finite element software.Based on the results from mechanical analysis on those relevant models,the four distribution rules were translated into the design rules and a structural bionic design for the working table was achieved.Both simulation and experimental verifications were carried out,and results showed that the average displacement of the working table was reduced by about 33.9%. | XING DengHai CHEN WuYi ZHAO Ling MA JianFeng | 2012 | Science China(Technological Sciences)2012，55，8： | 6 |
| 12 | Interactive early warning technique based on SVDD显示文摘After reviewing current researches on early warning,it is found that 'bad' data of some systems is not easy to obtain,which makes methods proposed by these researches unsuitable for monitored systems.An interactive early warning technique based on SVDD (support vector data description) is proposed to adopt'good'data as samples to overcome the difficulty in obtaining the'bad'data.The process consists of two parts:(1)A hypersphere is fitted on'good'data using SVDD.If the data object are outside the hypersphere,it would be taken as'suspicious';(2) A group of experts would decide whether the suspicious data is'bad'or'good',early warning messages would be issued according to the decisions.And the detailed process of implementation is proposed.At last,an experiment based on data of a macroeconomic system is conducted to verify the proposed technique. | Lin Jian~(1,2) Peng Minjing~(1,2) 1.School of Business Administration,South China Univ.of Technology,Guangzhou 510641,F.R.China 2.Systems Science & Technology Inst,Wuyi Univ.,Jiangmen 529020,P.R.China | 2007 | Journal of Systems Engineering and Electronics2007，18，3： | 6 |

| 14 | The Research of the Equation Model on the System-level Fault Diagnosis显示文摘In this paper we propose an equation model of system-level fault diagnoses, and construct corresponding theory and algorithms. People can turn any PMC model on ex-test into an equivalent equation (or a system of equations), and find all consistent fault patterns based on the equation model. We can also find all fault patterns, in which the fault node numbers are less than or equal to t without supposing t-diagnosable.

| 15 | Positioning error compensation for parallel mechanism with two kinematic calibration methods显示文摘Compared with serial mechanisms, the parallel mechanism(PM) theoretically exhibited higher positioning accuracy, dynamic performance, strength-to-weight ratio, and lower manufacturing cost, but they had not been widely used in the practical application. One key issue, positioning accuracy, which directly affected their performance and was greatly influenced by the errors of kinematic structure parameters was analyzed. To effectively enhance the positioning precision of PMs, a novel modeless kinematic calibration method, namely the split calibration, was presented and its compensation effect of the positioning error was comprehensively compared with that of an integrated method on two different types of PMs. A strange phenomenon-correct and incorrect identified results were derived from two different PMs by the same integrated method, respectivelywhich had not been reported yet was discovered, and the origin of it was revealed utilizing numerical simulations. Finally, respective merits and drawbacks of these two methods obtained in this paper provided underlying insights to guide the practical application of the kinematic calibration for PMs. | Guohua ZHAO Dan WANG Liangbao LIU Jiangzhen GUO Wuyi CHEN He LI | 2020 | Chinese Journal of Aeronautics2020，33，9： | 4 |
| 16 | Spatio-temporal measures of electrophysiological correlates for behavioral multisensory enhancement during visual,auditory and somatosensory stimulation:A behavioral and ERP study显示文摘Multisensory enhancement,as a facilitation phenomenon,is responsible for superior behavioral performance when an individual is responding to cross-modal versus modality-specific stimuli.However,the event-related potential(ERP)counterparts of behavioral multisensory enhancement are not well known.We recorded ERPs and behavioral data from 14 healthy volunteers with three types of target stimuli(modality-specific,bimodal,and trimodal)to examine the spatio-temporal electrophysiological characteristics of multisensory enhancement by comparing behavioral data with ERPs.We found a strong correlation between P3latency and behavioral performance in terms of reaction time(RT)(R=0.98,P<0.001),suggesting that P3 latency constitutes a temporal measure of behavioral multisensory enhancement.In addition,a fast RT and short P3 latency were found when comparing the modality-specific visual target with the modality-specific auditory and somatosensory targets.Our results indicate that behavioral multisensory enhancement can be identified by the latency and source distribution of the P3 component.These findings may advance our understanding of the neuronal mechanisms of multisensory enhancement. | Wuyi Wang Li Hu Hongyan Cui Xiaobo Xie Yong Hu | 2013 | Neuroscience Bulletin2013，29，6： | 4 |

| 18 | Research on optimization and design methods for air distribution system based on target values显示文摘To achieve sufficient air conditioning of large buildings,reasonable air distribution in indoor spaces is an effective method for creating stratified air conditioning.Therefore,optimizing the air distribution in large buildings is extremely significant.In this paper,we expound on a new method for air distribution design and optimization based on target value evaluation and summarize the relevant design processes based on an orthogonal test and by decoupling the effects of the size of the tuyere,airflow temperature,air-supply angle and velocity on air distribution.Then,we present a design case.To optimize the distribution of a lateral air supply in winter,the deflection angle,velocity and temperature of the air supply can be determined in turn.For the large and tall building types addressed in this paper,the optimal air-supply angle is 2°,the optimal air-supply velocity is 8 m/s,and the optimal air-supply temperature is 19℃. | Ran Gao Hengchun Zhang Angui Li Shihao Wen Wuyi Du Baoshun Deng | 2021 | Building Simulation2021，14，3： | 3 |

| 20 | A Virtual Machine Scheduling Strategy with a Speed Switch and a Multi-Sleep Mode in Cloud Data Centers显示文摘With the rapid growth of energy costs and the constant promotion of environmental standards, energy consumption has become a significant expenditure for the operating and maintaining of a cloud data center. Io improve the energy efficiency of cloud data centers, in this paper, we propose a Virtual Machine (VM) scheduling strategy with a speed switch and a multi-sleep mode. In accordance with the current traffic loads, a proportion of VMs operate at a low speed or a high speed, while the remaining VMs either sleep or operate at a high speed. Commensurate with our proposal, we develop a continuous-time queueing model with an adaptive service rate and a partial synchronous vacation. We construct a two dimensional Markov chain based on the total number of requests in the system and the state of all the VMs. Using a matrix geometric solution, we mathematically estimate the energy saving level and the response performance of the system. Numerical experiments with analysis and simulation show that our proposed VM scheduling strategy can effectively reduce the energy consumption without significant degradation in response performance. Additionally;we establish a system utility function to trade off the different performance measures. In order to determine the optimal sleep parameter and the maximum system utility function, we develop an improved Firefly intelligent searching Algorithm. | Shunfu Jin Shanshan Hao Xiuchen Qie Wuyi Yue | 2019 | Journal of Systems Science and Systems Engineering2019，28，2： | 2 |
