1. This paper deals with the development of acoustic pyrometry at home and abroad.

2. Experiment on acoustic pyrometry is done using the chirp signal, white noise and sine wave respectively in a 300MW boiler in one domestic power plant, through fire hole on furnace wall.

3. In the research of primary spectrum pyrometry , this paper discussed the definition problem of radiation temperature measurement area based on the measurement coordinates.

4. This thesis based on high temperature measurement and optical fiber sensor technology, take a study of ordinary multimode fiber optical fiber and sapphire colorimetry pyrometry technique.

5. It is useful to the measurement of transmitted time of sound wave in acoustic pyrometry and to the sound source location of 'four-tubes' leaking in boiler based on TDE.

6. It has a description of the principle of measuring temperature using acoustics pyrometry, as well as the basic structure of the temperature measuring system.
