摘　　要： 本文报导以重力式热管原理实现的双温度大面积蜂窝黑体辐射源装置。该黑体工作温度为40～150℃,有效面积为420×234mm^2。每个黑体工作面上温度分布的最大温差在1.9℃以内,面黑体的轮廓尺寸就是它的有效等温区。以重力式热管原理实现面黑体,这在技术上是一个新的尝试。从实验结果看出,面黑体工作面温度分布非常均匀,可见这一尝试是可行的。 A multiple-celled large-area blackbody source with an operating range of 40℃to 150℃ and effective area of 420×234mm^2,utilzing H_2O/Cu gravity-heatpipe for uniform-and stable temperature control,has been developed in this paper.The temperaturedifference on each working surface of the blackbody source apart from small part of it'sedge and angular area,is not more than 1.5℃ and the total working area is the effectivearea of uniform temperature distribution.It is a new idea that principle of gravity-heatpipe is applied to construct large-area blac-kbody source.The experimental results show that the temperature distribution on the wor-king surface of the blackbody is even and it is proved to be that this practice is success-ful.
