| 摘 要： | A much better substitutional means is discussed to calculate the flame temperature field with the application of digital image processing technology. Three non-contacting temperature measurements are used and compared. Such as the traditional two-color temperature measurement,the CCD filtering two-color temperature measurement and the monochromatic temperature measurement. It is indicated that the CCD two-color temperature measurement is not a fully correct means because of its poor theoretical basis. The monochromatic temperature measurement acquires a relatively ideal temperature field distribution in spite of needing a reference temperature. It should be noted that the Abel transformation applied in the plasma diagnosis is for the first time introduced to solve the problem of three-dimensional flame brightness piling.
