材料动力损伤的相似性

A STUDY OF THE GROWTH INTERFACES OF DIAMOND UNDER HIGH TEMPERATURE AND HIGH PRESSURE

从理论上推导了材料中空洞分布函数，阐明两种材料，Ｆｅ和Ｔａ样品，受不同飞片速度冲击后，其空洞分布的相似性。从文献［５］中又发现，脆性材料的裂纹分布也具有同样的相似性，这说明理论分布函数可能具有普遍性。最后提出了这种性质的广阔应用前景。

The growth interface of diamond crystal and the catalytic alloy film graphite interface were measured by using a scanning electron microscope and Auger scanning microprobe.The groove structures on the catalytic alloy film surface,the diamond surface and the transition layer have been observed.There exist marked differences in the shapes and relative energies of Auger spectra of carbon atom.The changes in line shapes and relative energies of these Auger line difinitely reflect the differences in the wave functions of the 2 s and 2p electrons in carbon atoms,in graphite and diamond cryslal,respectively.
