一、检定的原理与方法辐射高温计系以黑体热辐射的规律为基础而设计成的测温仪器,所以检定这种温度计时,以黑体辐射作为基础进行检定。这是最正确的而且又是传统的方法。过去,使用的检定方法不外乎下列两种,其一是以热电偶或光学高温计作标准,用黑体辐射作为介质加以比较;另一种是在大量的定点金属熔块中

First, the verification principle and method Radiation Pyrometer to blackbody heat radiation based on the law designed as a temperature measurement instrument, so test this thermometer, blackbody radiation as a basis for testing. This is the most correct and yet traditional method. In the past, the use of the test method is nothing more than the following two, one is a thermocouple or optical pyrometer as a standard, with blackbody radiation as a medium to be compared; the other is in a large number of fixed-point metal frit
