| 摘 要： | 测量固体的热扩散率和比热,一般是把试样简化为一维模型来处理的,并且不考虑热辐射损失的影响。本文介绍一种把试样作为二维模型,同时考虑热辐射损失影响的较精确的测量原理和装置。

| Abstract: | To measure the thermal diffusivity and special heat of a solid, thetest piece of the material will generally be simplified as a one-demensional modelwithout considering the loss of thermal radiation. This article introduces a principleof measurement and a device that simplifies the test piece of the material, takinginto consideration the loss of thermal radiation. The new methed is more precisethan the traditional one. |
