英文摘要：

Based on the principles of thermal radiation and temperature measurement with infrared thermal imager, a general computing formula of the true surface temperature of a measured object is given in order to increase the veracity and precision of a measure result. The aspects are expatiated which affect the precision of temperature measurement but are liable to be ignored in the course of temperature measurement with infrared thermal imager. Solutions therewith are also given.
