太阳集热管吸收表面光学性能的直接测量

DIRECT MEASUREMENT OF THE ABSORBING SURFACE SPECTRUM FOR SOLAR COLLECTOR TUBE

利用分光光度计的积分球对太阳集热管选择性吸收表面的镜面反射和漫反射光谱性能直接测量,通过修正之后可以得到与平面样品几乎相同的结果,实现了对产品的无损检测。

The spectrum reflectance, including specular and diffuse reflectance, of the solar collector tube was measured directly by the integrating sphere of spectrophotometer. After being modified, the measuring result is extremely close to that of the flat sample, it is possible to make the non-destructive examination on the collector tubes.
