摘要
研制了正辛烷/不锈钢热管式黑体辐射源。该源最大口径φ60mm,工作温度为(50～200)℃。实验测定,空腔温度均匀性在±0.1℃以内,控温稳定性优于0.03℃/30min。空腔有效发射率达0.998以上。
An n-octane/stainless steel heat pipe blackbody has been developed with maximum cavity diameter of 60 mm arid working temperature range from 50℃ to 200℃. Experimental results show that the temperature uniformity of cavity is better than±0.1℃, and the temperature stability better than 0.03℃/30 min. The estimated effective, emissivity under maximum cavity diameter is higher than 0.998.
