| 摘 要： | 根据S.K.Sharma[Mod.Phys.Lett.B 22/31(2008)3113]提出的等温体积弹性模量的一阶压强导数与体积压缩比的k次方成比例的假设,本文得到一个新的反映等温体积弹性模量随体积变化的表达式B(V),进而得到一个新的物态方程.利用B(V)表达式和新的物态方程分别对固体H2和D2计算了等温体积弹性模量和压强随体积的变化关系,计算结果与实验数据取得很好的一致性.与早期工作者的同类研究的比较分析表明本文提出的反映固体等温体积弹性模量和压强随体积变化的关系式具有更好的适用性.

| Abstract: | Based on the assumption,as suggested by S.K.Sharma [Mod.Phys.Lett. B 22/31(2008) 3113],that the first pressure derivative of isothermal bulk modulus B is in proportion to the k-th power of volume compression ratio,a new relation for the volume dependence of B and thus a new equation of state for solids at high pressures are obtained.The tests on H2 and D2 demonstrate that the calculated results given by the two expressions,respectively,are in good agreement with the corresponding experimental data.The comparisons with the other similar relations given by earlier workers lent support strongly to the applicability of the expressions presented here for predicting the volume dependence of B and P in solids. |
