Abstract: Assuming that the Anderson-Grneisen Parameter T(T, p)=T(T, 0), an approximate relation between cubical thermal expansion coefficient of solids and pressure was derived using the modified Tait equation. Calculated results are in good agreement with experimental data for NaCl in the pressure range of 0~1 GPa and the temperature range of 300~800 K.-
