THE SEEPAGE CHARACTERISTICS OF HETEROGENEOUS BODY WITH DIFFERENT SPREADING SOLUTION MODES AND ITS APPLICATIONS J. Zhang1,A.X. Wu2,H.J. Wang2,X.S. Chen1 (1.School of Resources and Safety Engineering... heterogeneous body, the seepage was different with varied spreading solution modes. The phenomenon of lamination that occurred in the site was simulated using three layers in an indoor experiment......
Fast weighting method for plasma PIC simulation on GPU-accelerated heterogeneous systemsYANG Can-qun(杨灿群), WU Qiang(吴强), HU Hui-li(胡慧俐), SHI Zhi-cai(石志才), CHEN Juan(陈娟), TANG Tao(唐滔)(School of Computer Science, National University of Defense Technology, Changsha 410073, China)Abstract:Particle-in-cell (PIC) method has got much benefits from GPU-accelerated heterogeneous systems. However......
Interference management via access control and mobility prediction in two-tier heterogeneous networksXIAO Zhu(肖竹)1, 2, CHEN Jie(陈杰)1, WANG Dong(王东)1, LI Ren-fa(李仁发)1, YI Ke-chu(易克初)2(1. College... heterogeneous networks (HetNets), where the current cellular networks, i.e., macrocells, are overlapped with a large number of randomly distributed femtocells, can potentially bring significant benefits......
with the increase of mass fraction of Al-5Ti-0.2C refiner but decrease little when the mass fraction is over 0.5%. TiC particles are the nucleants of heterogeneous nucleation, and these particles...; 文章编号:1672-7207(2015)08-2837-06 Effect of Al-5Ti-0.2C refiner on nucleation and undercooling degree of 7085 aluminum alloy NING Jiajie, LI Xiaoqian, JIANG......

. The mean reaction speed and plating per unit mass TiC are 0.013 g/min and 0.8 g, respectively, and the reaction time is about 60 min. The heterogeneous nucleation of nickel occurs in the bench-shape..., and the process parameters were optimized. The surface morphology, nucleation growth mechanism and phase component of the optimized TiC powders coated by pure nickel were studied using DSC, XRD, SEM......
