摘要：
A method for analyzing a temperature of exhaust gas includes calculating an approximate temperature at least one time by fitting a measured spectrum to a portion of theoretical spectra defined in association with a first temperature range using a temperature determined in the an immediately previous preceding temperature analysis as a reference, and then determining a calculated temperature by fitting the measured spectrum to all the theoretical spectra over a second temperature range that is narrower than the first temperature range, using the approximate temperature as a reference.
