of random fluctuating wind speed based on wavelet method[J]. Journal of Tongji University: Natural Science, 2005, 33(4): 427-431. [4] 胡亮, 李黎, 樊剑. 基于特征正交分解的桥梁风场模拟[J]. 武汉理工大学学报: 交通科学与工程版, 2008, 32(1): 16-19.HU Liang, LI Li, FAN Jian. Digital simulation of bridge wind fields based on spectral representation method with proper orthogonal decomposition[J]. Journal of Wuhan University of Technology......
delivery method for single and multiple copies is difficult to reconcile in one strategy. Obviously, there exists a local network model in the real world, that is, a non-connected network can be divided... information sharing among nodes. 2) Based on mobility pattern or social model, the method was proposed based on social network characteristics in real life [13]. Nodes in real-life tends to visit some......
removal 1 Introduction Arsenic contamination is a worldwide problem, and the safe treatment of arsenic is becoming a focus. The current method to treat arsenic is to transform arsenic into insoluble... dust, which was generated in zinc and lead production by reduction-roasting method from fuming furnace or rotary kiln. Several methods were reported on the treatment of secondary zinc oxide......
. A good electrolyte material should have high density (over 98%), high ionic conductivity, low thermal expansion and negligible electronic conductivity. Classical solid-state method needs the sintering temperature in the range of 1500-1600 ℃ to prepare dense ceramics and the main problems in this method are the lack of homogeneity in mixing materials and microstructure at such high sintering......
heat-treatment in the hot tandem rolled sheets. Obtaining a strong cube texture before cold rolling is a widely accepted method to solve this problem, which leads to a relatively homogeneous... on the investigation of stress relaxation of AA5182 during hot deformation, a new method to model the recovery process in the aluminum alloy has been provided by BANGE [8]. Due to the requirement of high quality......
method, the objective of the present work was to 1) determine chemical fractions of Pb in a soil irrigated with sewage in the Pearl River Delta, South China, 2) access the potential mobility of Pb... zone (0-60 cm, each sample was collected at continuous intervals of 10 cm), and the total number of soil samples was 32. The soil samples were collected by diagonal method with 0.5 m2. Each soil sample......
by environmental protection agencies. Pyrometallurgical and hydrometallurgical processes are usually applied to treating such residue. An ordinary pyrometallurgical method is Waelz process, in which zinc leaching... are vaporized in the kiln and then reoxidized and collected as a crude zinc-bearing product which are further refined and subject to acid leaching. A major disadvantage of pyrometallurgical method is high......
Trans. Nonferrous Met. Soc. China 23(2013) 1413-1420 Silicon/flake graphite/carbon anode materials prepared with different dispersants by spray-drying method for lithium ion batteries Jun LAI, Hua... conductivity and stress-buffer effect of carbon [13-17]. The preparation method of Si/C composite anode is also important for producing a Si/C composite anode with good electrochemical performance......
complex overlopping process such as atom clustering, spinodal decomposition, nucleation, disordered-order transition, growth and coarsening. 2 Model and method The microscopic phase-field kinetics model created by KHACHATURYAN [19] and developed by CHEN et al [20] is a kind of phase-field method, which uses atom transition probability (occupation probability) of the lattice as the field variables......
is an effective method to prepare metal-semiconductor nanocomposites [1,9,10,12]. The structures of these nanocomposites can be modified by adjusting the mixing ratios of the nanoparticles [9,10,12]. YANG... was distilled using a water distillation system (Dongwon Scientific., Ltd.). Gold nanoparticles (GNPs) were synthesized following the method developed by BRUST et al [13]. To develop positive charges......
