对高温热电偶在稳定性方面提出像低温热电偶同样的要求。但是由于在高温下所有元素的原子的剧烈的热运动和活性,那样高的稳定性根本无法保证。在高温下热电极材料与周围介质之间的相互化学作用具有特殊意义。因此,实际上不可能创制出一种能在高温下在氧化、还原、含炭及其他各种气体介质中都同样稳定的通用热
On the stability of high-temperature thermocouples made the same requirements as low-temperature thermocouples. However, due to the intense thermal movement and activity of the atoms of all the elements at high temperatures, the high stability can not be guaranteed at all. The interaction between the hot electrode material and the surrounding medium at high temperatures is of special significance. Therefore, it is virtually impossible to create a universal heat that is equally stable at high temperatures in oxidation, reduction, carbon-containing and various other gaseous media
