There exist two groups of factors responsible for distorsion of thermograms, these are a subdued temperature relief due to thermal conduction of tissues and equipment-caused distorsions. Such distorsions lower the informativeness of thermograms which hampers the selection of diagnostic signs. A method is proposed which enables it to partially compensate distorsions through application of Viener's method of re-establishing distorted images, based on the use of the à priori information on the distribution of temperature on the surface of the body and on the probable properties of thermal fields. The equipment-caused distorsions are then considered to be insignificant. The proposed algorythm of re-establishment has been tried out on the image of blood vessels in the rabbit's ear and on the factual image of the thermal field, the thermograms of mammary glands.

Experiments carried out on molybdenum have shown that monolithic materials of varying degrees of strengthening can be produced by subjecting powders of refractory metals to laser irradiation or to the action of SWs.

When zirconium carbide is irradiated by a laser beam, macrocracks appear after a certain time (10−3 sec) toward the end of the laser pulse.

Examples are cited of cases where heating with laser light pulses results in the formation of solid solutions (iron-carbon, iron-tungsten, etc.) and/or compounds (cobalt-tungsten, aluminum-niobium, iron-silicion, etc.).
