This paper inferred the calibration equation of the homogeneous tempera- ture and the dec}epitated temperature of inclusions in minerals according to the principle of expanding and contracting, and explained the calibration method of the data of thermometry by examples for actual inclusions. The calibration equations ; T(f) =A(Pf - Pd) + Td T(f) =A(Pf - Ph) + Th T(d) =A(Pd - Ph) + Th Tf, Pf，,the formation temperature and pressure;Td，Pd, the decxepitated temperature and the pressure;Th，Ph,the homogeneous temperature and the pressure; A the calibration coefficient. It equalled specific value K/β. This equation shows, whether the homogeneous temperature or the deare- pitated temperature, the pressure calibration monomial is AΔP from actual capture temperature of inclusions. Thus the data of measuring temperature without proofreading can not be directly in place of the formation temperature of the mineral. The homogeneous method determined the data of some early synthetic crystals practised proofreading abroad by the calibration equation and compa- red it with the actual synthetic temperature of crystal.The result of calibra- tion, the most error is ≤ ±5° The result of calculation is satisfactory and these equations approximated well .
