| 摘 要： | 利用中等密度的多孔钼烧结体进行了中、低静压全程加载-卸载实验。研究了在不同直径（特别是较大尺寸）和不同初始密度时该材料的静压p-V特性曲线。实验发现，样品初始密度不同应变也不同；卸载曲线几乎不受样品初始密度、直径的影响。计算表明，泡沫钼在静压下具有较高的吸能性，吸能效率较高，但预压后的泡沫钼吸能性和吸能效率均有所下降。 |

| Abstract: | Loading-unloading experiments on mid-density sintered porous Mo specimen were conducted under hydrostatic pressure. Under the circumstance, the p-V characteristics of foamed material with different diameters and initial density were first studied. Certain evidences show that strain amplitude in samples is correlated with initial density; but unload curves do not depend on initial density and diameter of specimens. Foamed Mo samples appear have higher energy absorbing capacity and efficiency based on calculated results. However, both the excellence relate to energy are somehow decreased after pre-pressured to the specimens. |
| Keywords: | foam porous material molybdenum density air void ratio absorbing efficiency |
