用新型红外测温仪观察由钨丝电子发射引起的损耗
Using new infrared thermoscope to observe the loss caused by electron emission of tungsten filament
【摘要】 在金属电子逸出功测定实验中,未考虑由钨丝电子发射引起的损耗,存在约-1.86%的系统误差.用新型红外测温仪可以观察到因上述损耗而出现的钨丝温度的变化,为修正该系统误差提供直接的观察依据.
【Abstract】 The experiment of measuring metal electron work function usually neglects the loss caused by the electron emission of tungsten filament,so the system error will be-1.86%.We can observe the change of tungsten filament temperature by using the new infrared thermocope,it offers direct observational basis for revising the system error.
