本文采用激光全息摄影技术记录激光加热下的单颗粒煤在某一时刻燃烧的全息图，通过再现系统和数字图象处理过程而获得二维的温度场分布，为研究煤的着火与燃烧的特性提供了一种新方法．同时采用了数学模型对几种煤从着火到燃尽时其周围的温度场进行计算，与实验进行了比较，得到了较为一致的结果．
In this paper, laser holographic recording technique was used to record the holograms of single coal particles burned by laser heating at a certain moment. Two-dimensional temperature field distributions were obtained through the reproducing system and digital image processing. In order to study the characteristics of ignition and combustion of coal, Provide a new method. At the same time, the mathematical model was used to calculate the temperature field around the coal from the ignition to the burn-out. Compared with the experimental results, we obtained the more consistent results.
