J. Cent. South Univ. Technol. (2009) 16: 0166-0171 DOI: 10.1007/s11771-009-0028-0 Formation mechanism of aerodynamic drag of high-speed train and some reduction measures TIAN Hong-qi(田红旗)1, 2...; Abstract: Aerodynamic drag is proportional to the square of speed. With the increase of the speed of train, aerodynamic drag plays an important role for high-speed train. Thus, the reduction......
of resources [1,2]. The reduction roasting process, as a common method of solid-waste treatment [3,4], has been found to be a productive means of decomposing zinc ferrite in high iron-bearing zinc.... The reduction mechanism of electric arc furnace dust pellets was similar to that of zinc ferrite. The diffusion of zinc ions in the solid phase was also reported to be the rate-determining step when zinc......
