| 英文摘要: |
| This paper deals with the development of acoustic pyrometry at home and abroad.It has a description of the principle of measuring temperature using acoustics pyrometry,as well as the basic structure of the temperature measuring system.In addition,this paper refers to some critical technology in the temperature measuring system,such as acoustic transceiver units,the measurement of the time of flight between two acoustic transceiver units,and the algo-rithm in reconstructing the temperature field.In this paper,it also has a discussion on the influence of multi-phase medium on the acoustic wave transmission,an analysis of lineup form of the acoustic transceiver units,and description of the impact on temperature field reconstruction.Finally,it foresees the development of acoustic measurement techniques. |
