| Abstract: | The change of emissivity measured is the main factor which influence the measurement accuracy. By analysis of the characteristics and ralationships between emissivity and material. surface condition. temperature. wavelengh as well as distributive direction. are given. The methods for calculating the temperature error caused by the change of emissivity and selections of measuring system according to the changes of the emissivity. |
