Abstract :
There are two conclusions, from the point of view emissivity measurement error and measurement wavelength, analysis casting radiation thermometry. One is that fixed wavelength is precise to full wavelength in radiation thermometry at the same condition. The other is that the wavelength is short and the measurement error is small in fixed radiation thermometry. Those conclusions provide theory base for the casting radiation thermometry design.
