在研究器件的热特性时,常常需要测量固体瞬态表面温度。例如,在研究诸如炮筒、激波管或火箭喷嘴中高温气体现象时,由外部热源加热的表面温度是很重要的。同样,在研究内部热的产生或热传递时,也常常会遇到要在那些仅仅与样品内部发生能量交换的表面上测量温度。 In studying the thermal characteristics of devices, it is often necessary to measure the solid transient surface temperature. For example, the surface temperature heated by an external heat source is important when studying phenomena of hot gas such as in a barrel, shock tube, or rocket nozzle. Similarly, when studying internal heat generation or heat transfer, it is also often encountered to measure the temperature at those surfaces that only exchange energy with the interior of the sample.
