低温装置材料表面辐射系数实验研究

Experimental Study on Surfaces' Emissivity of Cryogenic Devices

材料表面辐射系数与材料的种类、壁面的温度以及材料的表面状况有关。文中对不同材料的不同表面和不同温度情况下的辐射系数进行了实验研究 ,为低温装置系统表面处理工艺方法提供了依据。

The emissivity of object surface is decided by its material, temperature and roughness. From the test of emissivity between different surfaces at different temperature, this paper finds a economic way to treat the surfaces of the cryogenic devices.
