| 1 | Statistical and frequency analysis of the pressure fluctuation in a fluidized bed of non-spherical particles显示文摘In this paper,the pressure fluctuation in a fluidized bed was measured and processed via standard deviation and power spectrum analysis to investigate the dynamic behavior of the transition from the bubbling to turbulent regime.Two types[Geldart B and D) of non-spherical particles,screened from real bed materials,and their mixture were used as the bed materials.The experiments were conducted in a semiindustrial testing apparatus.The experimental results indicated that the fluidization characteristics of the non-spherical Geldart D particles differed from that of the spherical particles at gas velocities beyond the transition velocity U_c.The standard deviation of the pressure fluctuation measured in the bed increased with the gas velocity,while that measured in the plenum remained constant.Compared to the coarse particles,the fine particles exerted a stronger influence on the dynamic behavior of the fluidized bed and promoted the fluidization regime transition from bubbling toward turbulent.The power spectrum of the pressure fluctuation was calculated using the auto-regressive(AR) model;the hydrodynamics of the fluidized bed were characterized by the major frequency of the power spectrum of the pressure fluctuation.By combining the standard deviation analysis,a new method was proposed to determine the transition velocity U_k via the analysis of the change in the major frequency.The first major frequency was observed to vary within the range of 1.5 to 3 Hz. | Honghao He Xiaofeng Lu Wei Shuang Quanhai Wang Yinhu Kang Liyun Yan Xuanyu Ji Guangyu Luo Hai Liu | 2014 | Particuology2014，12，5： | 6 |
| 2 | General Attribute Based RBAC Model for Web Services显示文摘Growing numbers of users and many access policies that involve many different resource attributes in service-oriented environments cause various problems in protecting resource. This paper analyzes the relationships of resource attributes to user at- tributes based on access policies for Web services, and proposes a general attribute based role-based access control(GARBAC) model. The model introduces the notions of single attribute ex- pression, composite attribute expression, and composition permis- sion, defines a set of elements and relations among its elements and makes a set of rules, assigns roles to user by inputing user’s attributes values. The model is a general access control model, can support more granularity resource information and rich access control policies, also can be used to wider application for services. The paper also describes how to use the GARBAC model in Web services environments. | ZHU Yiqun LI Jianhua ZHANG Quanhai | 2008 | Wuhan University Journal of Natural Sciences2008，13，1： | 3 |
| 3 | Stable Ni-rich layered oxide cathode for sulfide-based all-solid-state lithium battery显示文摘Sulfide-based all-solid-state lithium-ion batteries(ASSLIBs)are one of the most promising energy storage technologies due to their high safety and ionic conductivity.To achieve greater energy density,a Ni-rich layered oxide LiNi_(x)Co_(y)M_(1-x-y)O_(2)(NCM,MMn/Al,x≥0.6)is desirable due to its relatively high voltage and large capacity.However,interfacial side reactions between the NCM and sulfide solid electrolytes lead to undesirable interfacial passivation layers and low ionic conductivity,thereby degrading the electrochemical performance of NCM sulfide all-solid-state batteries.Herein,a time-/cost-effective sulfidation strategy is exploited to sulfidize a Ni-rich NCM_(88) cathode in a mixed gas atmosphere of N_(2) and CS_(2).A new type of cathode(NCM88-S)with an ultrathin(∼2nm)surface layer is obtained,which significantly reduces the interfacial side reactions/resistance and improves the interfacial stability.The resulting NCM_(88)-S/Li_(6)PS_(5)Cl/Li_(4)Ti_(5)O_(12) ASSLIB exhibits superior performance,including a high discharge specific capacity(200.7 mAh g−1)close to that of liquid batteries,excellent cycling performance(a capacity retention of 87%after 500 cycles),and satisfactory rate performance(158.3 mAh g^(−1) at 1C). | Yue Wang Zhixuan Wang Dengxu Wu Quanhai Niu Pushun Lu Tenghuan Ma Yibo Su Liquan Chen Hong Li Fan Wu | 2022 | eScience2022，2，5： | 2 |

| 11 | Investigation on lateral dispersion characteristics of fuel particles in dense phase zone of a large-scale circulating fluidized bed boiler under combustion conditions显示文摘The dispersion characteristics of fuel particles in the dense phase zone in circulating fluidized bed(CFB)boilers have an important influence on bed temperature distribution and pollutant emissions.However,previous research in literature was mostly on small-scale apparatus,whose results could not be applied directly to large-scale CFB with multiple dispersion sources.To help solve this problem,we proposed a novel method to estimate the lateral dispersion coefficient(Dx)of fuel particles under partial coal cut-off condition in a 35o MW supercritical CFB boiler based on combustion and dispersion models.Meanwhile,we carried out experiments to obtain the Dx in the range of 0.1218-0.1406 m2/s.Numerical simulations were performed and the influence of operating conditions and furnace structure on fuel dispersion characteristics was investigated,the simulation value of Dx was validated against experimental data.Results revealed that the distribution of bed temperature caused by the fuel dispersion was mainly formed by char combustion.Because of the presence of intermediate water-cooled partition wall,the mixing and dispersion of fuel and bed material particles between the left and right sides of the furnace were hindered,increasing the non-uniformity of the bed temperature near furnace front wall. | Zhongzhi Yang Xiaofeng Lu Zhonghao Dong Rongdi Zhang Jiayi Lu Jiayi Jue Baosheng Meng Quanhai Wang Yinhu Kang Jianbo Li | 2023 | Particuology2023，，7： | 0 |

| 13 | Study on the Medical Image Distributed Dynamic Processing Method显示文摘To meet the challenge of implementing rapidly advanced, time-consuming medical image processing algorithms,it is necessary to develop a medical image processing technology to process a 2D or 3D medical image dynamically on the web. But in a premier system, only static image processing can be provided with the limitation of web technology. The development of Java and CORBA (common object request broker architecture) overcomes the shortcoming of the web static application and makes the dynamic processing of medical images on the web available. To develop an open solution of distributed computing, we integrate the Java, and web with the CORBA and present a web-based medical image dynamic processing methed, which adopts Java technology as the language to program application and components of the web and utilies the CORBA architecture to cope with heterogeneous property of a complex distributed system. The method also provides a platform-independent, transparent processing architecture to implement the advanced image routines and enable users to access large dataset and resources according to the requirements of medical applications. The experiment in this paper shows that the medical image dynamic processing method implemented on the web by using Java and the CORBA is feasible. | Zhang Quanhai & Shi PengfeiInstitute of Image Processing and Pattern Recognition, Shanghai Jiaotong University, Shanghai 200030, P.
