用一实锥和一空锥构成二锥腔,付诸黑体模拟,得一双倒锥黑体腔。用它做一小黑体,标定结果,发射率ε=0.986,和设计值相近。同时介绍黑体配件——一个带风机廷时的黑体控温电路。
A solid cone and an empty cone form two cone cavity, put into blackbody simulation, get a pair of inverted cone blackbody cavity. Use it as a small black body, the calibration results, the emissivity ε = 0.986, and the design value is similar. At the same time introduced the black body parts - a black body temperature control circuit with fan Ting.
