Values of directional and hemispherical emittance of twelve coatings were needed in support of a spacecraft experiment. Laboratory measurements were made by two calorimetric and four reflectance techniques and with two portable devices designed for field or laboratory operation. The measurement results are compared, primarily on the basis of hemispherical emittance values deduced from each; and the limitations and uncertainties of each technique are summarized.
为支持一项航天器实验，需要测定12种涂层的定向发射率和半球发射率值。通过两种量热法、四种反射率测量技术以及两种用于现场或实验室操作的便携式设备进行了实验室测量。主要根据每种方法推导出的半球发射率值对测量结果进行了比较，并总结了每种技术的局限性和不确定性。
