The measurement of the total emissivity of a solid surface in the black cavity which is immersed in liquid nitrogen and under high vacuum ( 10-6 torr) by steady caloric method is described.
本文提出了一个真空度为10~(-6)毫米汞柱,黑体腔四周浸泡在液氮中的固体的表面热辐射率的测定方法。
In this lecture, emphasis is focused on the measuring principle of real temperature, and the masuring principle and method of the emissivity and total thermal current.
具体讲述真温度测量原理、发射率测量原理与方法、全热流测量原理与方法。
