摘要
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。
Considering special application, a small-size blackbody with two reversed cone cavities was designed and assembled. The emissivity oblained is 0.986, very close to the calculation value. The temperature controller and a fan-delay circuit a(?) necessary accessories are also presented.
