主　　题：thermal earth insulation 

摘      要：High-temperature infrared(IR)camouflage is crucial to the effective concealment of high-temperature objects but remains a challenging issue,as the thermal radiation of an object is proportional to the fourth power of temperature(T4).Here,we experimentally demonstrate high-temperature IR camouflage with efficient thermal *** combining a silica aerogel for thermal insulation and a Ge/ZnS multilayer wavelength-selective emitter for simultaneous radiative cooling(high emittance in the 5-8μm non-atmospheric window)and IR camouflage(low emittance in the 8-14μm atmospheric window),the surface temperature of an object is reduced from 873 to 410 *** IR camouflage is demonstrated by indoor/outdoor(with/without earthshine)radiation temperatures of 310/248 K for an object at 873/623 K and a 78% reduction in with-earthshine lock-on *** scheme may introduce opportunities for high-temperature thermal management and infrared signal processing.
