DEVELOPMENT OF A MILLISECOND PULSE-HEATING APPARATUS WITH A MULTI-WAVELENGTH PYROMETER AND AN INTEGRATING REFLECTOMETER FOR THERMOPHYSICAL PROPERTIES MEASUREMENT
脉冲加热材料热物性多光谱动态测量装置的研制

A millisecond pulse heating reflectometric technique with multi wavelength pyrometry to measure the thermophysical properties of a strip specimen was developed. The multi wavelength normal spectral emi ssivity of the strip were measured by a multi wavelength pyrometer and an integrating reflectometer. The measurement technique and components of the milliecond pulse heating apparatus are described. The heat capacity, electrical resistivity, total hemispherical emissivity and multi wavelength spectral emissivity of the specimen can be measured simultaneously by using this apparatus.
