摘　　要：在辐射测温仪工作波长的选择上，以往一直参照维思位移定律。通过理论分析，发现依照该定律选择测温仪工作彼长是不完善的。为了提高仪表灵敏度和测温准确度，推导出了一种新公式，提出了一种新的工作波长的选择方法，并在理论上证明该方法较目前常用的方法更为理想。Men selected radiation pyrometer's working wavelength according to Wien Law before. But by using of theoretical analysis, we find that this method is not perfect. To enhance the meter's sensitivity and measurement accuracy, we derive a new equation and find a new method for selecting working wavelength. Also proves in theory that this mithod is more effective than the others that are usually used.
