describe the adsorption of salicylic acid onto GQ-10 well if the adsorption process is divided into two stages, which is consistent with the pore structure of GQ-10.Salicylic acid is absorbed onto......
observed point in the given targets area instead of the physical transmission process of time-reversed signals, are refocused at source and the observed point whose energy value of virtual received sum......
in phosphoric acid. The corrosive attack of hydrochloric acid mainly corrodes the intergranular Nd-rich phase. And the acid solution penetrates to NdFeB matrix through the pores in the erosion process......
hysteresis on shapes, sizes and distribution density of condensed droplets and retained frost melting droplets are found to be significant. In addition, the defrosting process is faster on fin with bigger......
University, Tianjin 300072, China) Abstract: A four-electrode electrostatic sensor with local electrostatic sensibility was used for studying local flow characteristics in the pneumatic conveying process......
process, thus the p-s curve of single pile was obtained. The feasibility of the proposed method could be assessed by a comparison with existing methods. The effects of excavation depth on some key......
