Abstract:
A temperature measurement method for measuring temperature of a measurement target object to which a temperature sensor cannot be fixed directly, comprising:obtaining an observed temperature from the temperature sensor arranged in a vicinity of the measurement target object and a temperature observation time from a timer; and calculating the temperature of the measurement target object Tobj according to the observed temperature and the temperature observation time by a calculation processing based on a following equation (C): Tobj(t1)=GinÂ·f(&Dgr;tobs)Â·&Dgr;tobs+Tobj(t0)â€ƒâ€ƒ(C) where t1 is a current time at which the observed temperature is observed, t0 is a time at which temperature was measured last time, Gin is a time change rate of temperature applied to the measurement target object, f(&Dgr;tobs) is a polynomial regarding &Dgr;tobs, and &Dgr;tobs is a time interval by which temperature has been observed.
