| Abstract: | When the temperature of gas current is measured by thermo pair,the value error between the true temperature and the measured one is caused.This paper gives out the cause of the error and shows the way,how to minimize it.By particular calculating,the relation between the error and the position of the thermo pair in the thermo screen is dedicated in detail. |
