PASCO实验中Leslie辐射源的研究

Leslie辐射源是PASCO热辐射实验装置中的一个热源，它有四个不同表面的铝质正方体。通过实验测量Leslie辐射源不同表面的辐射情况，研究了辐射与表面温度、位置的关系，并阐述了粗糙面小孔不是黑体的实验依据。经过对采集数据的分析可以看出，实验结果与理论有较好的符合，对热辐射探测具有指导意义。

Investigation of Leslie Radiation Source in PASCO Experiment

Leslie radiation source is a heat source in PASCO thermal radiation experiment apparatus, and it is an aluminum cube that has four different surfaces. The relation among surface radiation and surface temperature and surface position is studied by experimentally measuring radiation of the different surfaces of Leslie radiation source. Besides, experimental basis for the fact that small holes on a rough surface do not form a blackbody is also obtained through the above measurement. It can be seen from the analysis of the collected data that experimental results shows a good accordance with theory and the rcsuit, and it can serve as a guidance for thermal radiation detection.
