The high-pressure compression behaviour of titanium dioxide (TiO₂) (Rutile phase), iron oxide (\(\gamma\)-Fe₂O₃), magnesium oxide (MgO) and copper oxide (CuO) nanomaterials are studied by several theoretical equation of state (EOS) model and compared with experimental results. In given theoretical EOS models, the pressure is considered as relative changes of volume and experimental data in terms of pressure. Moreover, the present EOS model specifies close conformity with the experimental data.

纳米材料二阶压力导数的体积模量

二氧化钛 (TiO ₂ ) (金红石相)、氧化铁 ( \(\gamma\) -Fe ₂ O ₃ )、氧化镁 (MgO) 和氧化铜 (CuO) 纳米材料的高压压缩行为通过几个研究理论状态方程（EOS）模型并与实验结果进行比较。在给定的理论 EOS 模型中，压力被认为是体积和实验数据在压力方面的相对变化。此外，目前的 EOS 模型指定与实验数据非常吻合。
