The process of heat transfer from a linear pulsed-heat 
source in a semibounded body has been investigated. A nondestructive 
method of determining the thermophysical parameters of a material 
by the working portion of its thermogram, which allows one to substantially 
decrease the measurement error, has been developed. Since the model 
developed is linear by the parameters used, it allows one to estimate, 
using classical statistical methods, the random error in measuring 
the thermophysical parameters of materials.
