对“含溶质体心立方铁的晶格参数和弹性刚度系数的从头计算”一文的评论。Sci. v.126 pp.503-513(2017)

摘要:

在最近的一篇论文中,作者建议分别计算含有溶质的系统的弹性刚度系数的体积和化学贡献,因为它“计算效率更高”。我们表明,情况并非如此,并进一步表明,他们的方法,因此他们的结果是不正确的。正如我们在2012年的工作中所展示的那样,如果严格执行,执行所需的计算是没有捷径的。

英文摘要:

In a recent paper, the authors propose to separately calculate the volumetric and chemical contributions to the elastic stiffness coefficients of systems containing solutes, as it is "computationally more efficient". We show that this is not the case and further that their methodology and hence their results are incorrect. There is no short cut for performing the desired calculations, if done rigorously, as we show in our 2012 work.
