【摘要】 用HD红外低温测温仪很简单地就可测定各种常温物体的比辐射率,其结果与文献上发表的相一致。在用测温仪测定室内各种常温物体的辐射温度时发现,它们的辐射温度几乎是相等的。为了解释这些实验现象,我们推导了相应的公式,认为在这种情况下必须考虑目标对环境辐射的反射。更多还原

【Abstract】 The emissivity of various room temperature materials may be measured simply by the HD Infrared Low Temperature Radiometer, the results of the measurement are in agreement with those of other articles.When the radiation temperature of various room temperature materials is measuredit is found that values obtained are nearly all the same. In order to explain these experimental results, the corresponding formulas are deduced, in these cases, the reflective radiation must be considered.更多还原
