【Abstract】 In the new non contact instrument of temperature measure , we ventilate the light way to blow away so as to eliminate the inaccuracy of the temperature measure which is caused by the vapors selective absorption of the radiation energy.we aiming to use the theory of heat exchange by cascading in the thesis to study the heat process between air stream and the casting flans, through ANSYS system analysis to confirm the effect of air cooling fator on measuring error, and put this theory into the research of the new type of instruments to asjust measuring error resulted from the casting flan temperature falling caused by blowing.更多还原
