【摘要】 文章讨论了在逸出电位测定过程中两种灯丝电流和加速电压的调节方法。认为如果先固定加速电压当灯丝电流增大后,会导致加速电压的减小,使测量逸出电位的不确定度增大。所以在这种调节方法中,应该增大加速电压值,这样测量精度更高。更多还原

【Abstract】 This article discussed that the filament current and accelerate voltage adjust ways to determine electric potential.If fixed voltage to raise filament current lead to accelerate voltage reduce.It caused large no definite degree.So this adjust way should amplify accelerate voltage.更多还原
