| 摘 要： | 本文给出了在大气温度下测量物质表面法向发射率的原理、装置结构及测试结果。这个装置是由黑体,样品腔和辐射计(接收元件)构成。法向发射率是由在相同温度下样品产生的热电势EMF与黑体产生的热电势EMFo之比来度量的。最后,对误差进行了讨论。

| Abstract: | The theory, structure of the device and test results of the measurements of the normal emittance of the material surface were given in the temperature of the atmospheric invironment. The device was consisted of a blackbody, a sample chamber and a radiometer (thermopile detector). The normal emittance was measured as the ratio of thermoelectric EMF generated by the sample to the thermoelectric EMF. generated by the blackbody at the same temperature. Finally, the measurement errors were discussed. |
