There are very few investigations on the measurements of total hemispherical emittance of non-metallic materials, in contrast to those on metallic materials. In this investigation, a method for simultaneous measurement of total hemispherical emittance, specific heat and themal diffisivity of non-metallic materials by means of a transient method has been developed.On measurements of thermophysical properties of non-metallic materials, there arises a problem of the thermal garadient produced in a specimen used. An improved transient calorimetric technique to reduced the thermal gradient is proposed in this study.Glass sheets semi-transparent for radiation are selected as a measured by the proposed technique and their results are presented with the thickness as parameter. The corner effect of the specimens due to the local hemispherical emittance distribution on the measured total hemispherical emittance is estimated. It is shown that the proposed technique is very useful for measuring total hemispherical emittance, specific heat and themal diffisivity of non-metallic materials.

与金属材料上的非金属材料相比，对非金属材料的总半球形发射的测量很少。在这项研究中，已经开发了一种通过瞬态方法同时测量总半球发射率，非金属材料的特异性热和正式扩散。在这项研究中提出了一种改进的瞬时量热量化技术，以减少热梯度。镜片板半透明的辐射片被选为通过所提出的技术测量的，其结果以参数为参数。估计了由于局部半球形发射率分布对测得的总半球形发射量引起的标本的角效应。结果表明，所提出的技术对于测量总半球形发射率，特定的热量和非金属材料的主体扩散非常有用。
