提出了利用Hugoniot数据、变形Morse势和Grüneisen模型来确定固体材料的高压状态方程的方法.该方法物理意义明确,表达式简洁.用此方法计算Au的高压状态方程,将所得的状态方程与Sesame数据库中Au的状态方程进行比较,发现在密度20～28 g/cm~3内两者吻合较好,相对误差在0～10%的范围内,表明运用Hugoniot数据结合Grüneisen模型计算材料的状态方程是很适合的.

Based on Hugoniot data, deformation Morse potential and Griineisen model, a new method is introduced to determine the equation of state of solid material under high pressure. Physical significance of the method is specific and expression form is concise. The equation of state of Au calculated by this method agrees well with that of Sesame equation of state database. The relative error is in the 0～10% range when the density of Au is within 20～28 g/cm~2.
