摘要：

In this paper, we present the results of the study of the spectral composition and temporal dynamics of optical emission during electrical explosion of a tungsten wire. It is found that the second emission peak similar to 1ms long appears at wire diameters exceeding 100 A mu m. At the same wire diameters, an intense continuous Plank spectrum is observed in the red region of the optical spectrum. During electrical explosion of wires less than 100 A mu m in diameter, the second intensity peak is absent, and the survey spectrum contains only atomic spectral lines. The assumption about the correlation of these two effects is made.
