General temperature measurement only considers the effect of convection and conduction on the thermocouple measurement and not consider the effect of thermal radiation.
一般温度的测量，只考虑对流换热对热电偶测温的影响，未考虑热辐射对热电偶测温的影响。

But when measuring high temperature, thermal radiation is stronger and has the great influence on the thermocouple accuracy of measuring temperature.
而进行高温测量时，辐射较强，热辐射对热电偶测温的准确性有较大影响。

In tests of combustor heat loss arises from radiation in measuring tempera-ture with a thermocouple.
