| 摘 要： | 通过假设泊松比率和无量纲参量在温度T高于德拜温度时与温度无关，推导出了体积弹性模量BT（T）和剪切模量G（T）与温度T之间的关系。将推得的关系式应用于计算8种矿物质的BT和G，所得结果与实验值符合得很好。

| Abstract: | In the present paper, the temperature dependence of the isothermal bulk modulus BT(T) and the isotropic shear modulus G(T) are investigated. The relationships for BT(T) and G(T) are discussed with the assumptions that the dimensionless thermoelastic parameter Γ and the isothermal Poisson's ratio σT are independent of temperature T when T is higher than the Debye temperature ΘD. These relations are used to calculate the values of BT(T) and G(T) at different temperatures T for eight minerals. The results are found to present close agreement with the experimental data. |
