Abstract： In this paper， the temperature measurement technology of thermocouple is introduced， the influence of three heat transfer modes on the wall temperature of thermocouple turbine blade is discussed， and the mechanism of temperature deviation from the measured point is studied. Considering the three heat transfer modes comprehensively， the heat balance model of thermocouple temperature measurement is established. According to the calculation formula， a set of thermal equilibrium is established， the temperature of the measured point is solved， and the correction method of temperature measurement is obtained.

Keywords： turbine blade; temperature deviation mechanism; thermal equilibrium model; temperature correction method
