| 摘 要： | Three thermodynamical equations, for unitary two-phase fluid inclusions have been deduced. (1) The thermodynamical equation for mutual transformation between gas and liquid phases in fluid inclusions. The transformation direction from one phase to the other can be known in terms of the density and filling degree of gas and liquid. (2) The thermodynamical equation for pressure effect on temperature after homogenization of fluid inclusions. The coefficient of P-T variation is directly proportional to the fining degree of gas phase and inversely to the density of gas phase and liquid phase. Equations for homogenization, decrepitation and formation temperatures of fluid inclusions can be inferred from. this equation. (3) The thermodynomical equation for decrepitation temperatures of fluid inclusions. Many factors have effects on the decrepitation temperatures of fluid inclusions.Decrepitation temperature cannot be considered in any case as formation temperature.Thermal and vapor halos produced by decrepitation of minerals of the same kind and the same period from the same locality are worthy of consideration.
