milling. The effects of Ni content and milling time on hydrogen storage thermodynamics and dynamics of the alloys were systematically investigated. The gaseous hydrogen absorption and desorption properties were investigated by Sieverts apparatus and differential scanning calorimeter connected with a H2 detector. Results show that increasing Ni content significantly improves hydrogen absorption......

by rapid solidification process to yield a maximum hydrogen absorption capacity of about 3.0%. In addition, the hydrogenation kinetics of the melt-spun Mg2(Ni, Y) have been observed to exceed... caused by Mn substitution reduces the ratios of expansion/contraction of the alloys in the process of the hydrogen absorption/desorption, which means increasing the anti-pulverization capability......
alloys LaNi 5 and MlNi 5 (Ml=lanthanum rich mischmetal) on structure, hydrogen content, hydrogen absorption capability and hydrogen equilibrium pressure of those hydrogen storage alloys was investigated. The phase structure was studied by X ray diffraction analysis. The hydrogen absorption and desorption pressure composition isotherms were measured under the temperature of 298 K, 313 K and 333 K......
; 文献标志码:A Effect of combining form on sound absorption of closed-cell aluminum foam perforated LIANG Li-si, YAO Guang-chun, MU Yong-liang, HUA Zhong-sheng (School of Materials.... The sound absorption coefficient was measured by standing-wave method, and the effect of combining form on the sound adsorption of closed-cell aluminum foam perforated was studied. The results show......
, the S20(the capacity maintain rate at 20 th cycle) value increases from53.2 % to 89.7 %, the hydrogen absorption saturation ratio(Ra5, a ratio of the hydrogen absorption quantity in 5 min to the saturated hydrogen absorption capacity) increases from36.9 % to 91.5 %, and the hydrogen desorption ratio(Rd10,a ratio of the hydrogen desorption quantity in 10 min to the saturated hydrogen absorption......
