一、引言1.评论在温度测量中,当高温计的光谱灵敏度在固定波长上用纯单色灵敏度近似时,会引起几开以上的系统误差。通常对这个误差修正的方法是用一个可变的有效波长来代替固定波长。这个波长的数值不再是一个仪器常数,而决定于高温计的光谱灵敏度 I. INTRODUCTION 1. Comments In the temperature measurement, when the spectral sensitivity of the pyrometer is approximated by the pure monochromatic sensitivity at a fixed wavelength, it can cause systematic errors of more than a few degrees. The usual way to correct for this error is to use a variable effective wavelength instead of a fixed wavelength. The value of this wavelength is no longer an instrument constant but depends on the pyrometer’s spectral sensitivity
