关于（MgFe）2SiO4物性参数计算公式的讨论

(MgFe)_2SiO_4是上地幔介质的主要成分,计算其物性参数有助于了解地球内部的物理状态和物理过程,是地学的基础性研究工作。Goto等曾给出(MgFe)_2SiO_4的物性参数,但其所用公式尚需作适当修正。本文在对Birch状态方程作进一步讨论的基础上,修正了Goto等的公式,并重新计算了(MgFe)_2SiO_4的密度、热膨胀系数和定压比热,在综述目前工作的基础上给出了热传导系数的计算结果。

Physical Parameters of (MgFe)_2 SiO_4

(MgFe)2 SiO4 is the major component of the upper mantle. The calculation of its physical properties should conduce to study the physical state and the physical process of the interior of the Earth, which is the basic work of the Earth Science. Goto et al. calculated the physical coefficients of (MgFe)2 SiO4, but the formula they used need to be modified properly. In this paper, on the basis of further discussion about the Birch state equation, the formula of Goto at al. 1] were modified, the Density, Volumetric thermal expansion coefficient and the Specific heat were calculated; On the basis of summarizing the results of the other scientists, the Thermal conductivit was calculated.
