摘要：
The location of the melting line in the phase diagram of methane was predicted using two theoretical equations of state: for solid and fluid phases. The equations of state for both phases are constructed in the framework of thermodynamic perturbation theory, considering the octupole-octupole interaction of methane molecules as a perturbation. The results of calculations of the melting line parameters are compared with experimental and computer simulation data.
