摘要

为了描述钽在冲击压缩波和等熵膨胀波中高压区域的热力学性质，提出了压力与比容和比内能的简单解析函数。在此状态方程的基础上，计算了钽在大范围的压缩和加热程度下的热力学特性。计算结果与已有的激波和中心简波钽实验数据进行了比较。上述状态方程可用于模拟高能量密度下的绝热波过程。

Equation of State for Tantalum at High Pressures in Waves of Shock Compression and Isentropic Expansion

A simple analytical function of pressure versus specific volume and specific internal energy is proposed for describing thermodynamic properties of tantalum in the region of high pressures in the shock-compression and isentropic-expansion waves. On the basis of this equation of state, thermodynamic characteristics of tantalum are calculated in a wide range of degrees of compression and heating. The results of the calculations are compared to the available tantalum data of experiments with shock and centered simple waves. The above equation of state can be used to simulate adiabatic wave processes at high energy densities.
