In the paper,fundamental theory and technology traits of infrared thermodiagnosis have been introduced briefly,with focus mainly on inverse heat conduction method.

Making use of infrared thermodiagnosis,a theory model is established based on the infrared temperature measuring.

According to the infrared thermodiagnosis,this paper takes an infinity flat as studying object.

The basic principle, characteristics of infrared thermal diagnosis technology are summarized and its application in power system is emphatically introduced.

The actual situation of a equipment is combined with infrared thermal diagnosis in the paper,and the inner surface equation of a three—dimensional flat equipment under Neumann condition is given.

Feasibility to the infrared thermo diagnosis of the defects in the inner wall of three dimensional cylinder shaped equipment by means of numerical experiment.

The paper described basis theory and general method of the infrared thermo diagnosis,it also stated working process of the method by giving an example of the cylinder-shaped equipment.
