Beschreibung
Zusammenfassung:	The invention provides a radioactively-selective absorbing coating. The radioactively-selective absorbing coating comprises a transition layer, an infrared reflecting layer, an absorbing layer and a reflection-reducing layer in sequence from the base to the surface, wherein the absorbing layer consists of two sublayers, i.e., a first sublayer and a second sublayer; the two sublayers are made of Mo-SiO2 or stainless steel-AlN materials; the volume percentage of the metal Mo or the stainless steel in the first sublayer is 20-40%, the volume percentage of the metal Mo or the stainless steel in the second sublayer is 10-30%, and the content of the metal in the first sublayer is greater than that of the metal in the second sublayer. The radioactively-selective absorbing coating provided by the invention adopts a MoCu or AgCu alloy film with a high melting point as the infrared reflecting layer, adopts stainless steel or molybdenum as a metal component of the absorbing layer, and has good high-temperature stability
