Application of new infrared thermometer in teaching practice

Diversity of heat radiation and identity of heat radiation theory are contradictory. But new infrared thermometer can solve this problem, and avoid the difficult of "specific radiation rate revise". In teaching practice , it is advangtageous at cultivating students' creative spirit and ability of solving practical problem. We can set up some courses, such as:experiment of infrared thermometry principle;the relationship of incandescent lamp heating electric current and filament temperature;improve measuring accuracy of metal (wolfram) electric work function. When boardcurrented output ,we can observe the temperature of filament reduce.
