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.

研制了一种新型的辐射测温仪。本研究采用的热分析法的原理是在没有任何物体发射率数据信息的情况下，测量波长为600 ~ 830 <mu> m的总辐射能量，并采用新开发的数据处理方法进行温度测定分析。新型高温计的主要优点如下：1)由于几乎可以同时获得不同波长值的多个辐射强度数据，因此可以大大提高温度测定的精度。2)采用单色或双色高温法，可方便地监测快速现象的温度变化，响应时间可达100 <mu> m。由于同时获得了温度和总辐射能量的数据集，因此可以对观测到的现象进行更广泛的分析。介绍了石墨颗粒燃烧的一些结果，作为新型高温计的应用实例。
