【Abstract】 In the present paper, the temperature dependence of the isothermal bulk modulus B T(T) and the isotropic shear modulus G(T) are investigated. The relationships for B T(T) and G(T) are discussed with the assumptions that the dimensionless thermoelastic parameter Γ and the isothermal Poisson’s ratio σ T are independent of temperature T when T is higher than the Debye temperature Θ D. These relations are used to calculate the values of B T(T) and G(T) at different temperatures T for eight minerals. The results are found to present close agreement with the experimental data.更多还原
