Development of a New Pyrometer Based on the Analysis of Thermal Radiation Spectrum.

研制了一种新型的辐射测温仪。该测温仪的工作原理是在不需要物体发射率数据的情况下，通过测量600 ~ 830 m波长范围内的辐射总能量<mu>，并利用新开发的数据处理方法进行分析，从而确定温度。该测温仪的主要优点是：（1）在测量过程中，不需要物体的发射率数据; 1）由于在不同波长下几乎同时获得了多个辐射强度数据，从而大大提高了温度测定的精度。2）快速现象的温度变化可以很容易地监测到，响应时间为100 m<mu>，3）由于温度和总辐射能量的数据组是同时获得的，对所观察到的现象进行更广泛的分析已成为可能。2作为应用这种新型高温计的一个例子，介绍了石墨颗粒燃烧的一些结果。

A new type of thermometer for radiation pyrometry was developed.The principle of the pyrometry employed in this study is based on the measurement of total radiation energy with the wavelength from 600 to 830 <mu> m and analysis by newly developed data processing method for determination of temperature without any information on the emissivity data of the object.Main advantages of the new pyrometer are as follows;1) Since a number of radiation intensity data are almost simultaneously obtained for different values of wavelength, the accuracy of temperature determination can be extensively improved.2) The temperature change of rapid phenomena can be easily monitored with responce time of 100 <mu> m, by application of the mono or two color pyrometry.3) Because the sets of data of temperture and total radiation energy are simultaneously obtained, more extensive analysis of the phenomenon under observation has become possible.Some results on the combustion of graphite particles were presented as an example of application of the new pyrometer.
