An Isothermal Equation of State for Solid (Ⅴ)-Equation of state at High Temperature
-
摘要: 本文以NaCl为例,证实了在我们的状态方程体系中,不同温度的状态方程可以认为是在px坐标系中不同起点开始的同一状态方程。于是,可由室温状态方程和常压热膨胀的测量数据估计高温状态方程。Abstract: In present work, using NaCl as an example, we proved that the equations of state of solid (EOS) at various temperatures can be considered in our px pressure coordinate as one EOS, in which they start at different points. Then the EOS of any material at high temperature can be estimated from the data of its EOS at room temperature and thermal expansion at atmosphere.
