摘要
本文提出一种利用材料Hugoniot数据研究高压下离子晶体中微观离子状态及其离子间排斥作用势的新方法。对氢化锂晶体进行研究时,我们得到Li^+和H^-离子之间排斥作用势函数,结果表明文献〔1〕中提出的离子压缩效应具有客观性。
This paper presents a new approach which can be applied to study the states of ions and the repulsive potential between ions in ionic crystals at high pressure, where the Hugoniot data are used. When analysing LiH crystal, we obtained the repulsive potential function between Li+ and H-, and the results show that the compression effect of ions mentioned in literature [1] seems to exist.
