Abstract

An experimental study of the normal spectral emissivity of technical nickel, palladium and platinum in the solid polished and liquid phases near the melting points was carried out by the radiation method. The emission measurement was recorded by the bandwidth of the applied narrowband filters. The dependence of metal emission on the wavelength in the range of the radiation spectrum 0.26–10.6 μm is obtained. A comparative analysis with the literature data of other authors is carried out. A theoretical calculation of the emission is given according to the classical electromagnetic theory Hagen’s formula and Rubens.

X 族过渡金属在熔点区域的光谱发射率

通过辐射法对工业镍、钯和铂在熔点附近的固态抛光和液态的正常光谱发射率进行了实验研究。发射测量是通过所应用的窄带滤光片的带宽来记录的。结果表明，在辐射光谱 0.26-10.6 μm 范围内，金属发射与波长有关。与其他作者的文献数据进行了对比分析。根据经典电磁理论哈根公式和鲁本斯公式对发射进行了理论计算。
