Summary

THE RESULTS OF A TEST STUDY OF THE THERMAL CONDUCTIVITY OF SOUND BIOLOGICAL TISSUES AND OF PATHOLOGICAL STRUCTURES IN THE TEMPERATURE RANGE 313 TO 77 K (40 TO -196 DEG C) ARE REPORTED. THERMAL CONDUCTIVITY WAS DETERMINED IN A TEST PLANT BY THE STATIONARY STATE METHOD. THE COMPLEX NATURE OF THE THERMAL CONDUCTIVITY-TEMPERATURE RELATIONSHIP WAS SHOWN: FOR TEMPERATURES HIGHER THAN 273 K (0 DEG C) IT IS PRACTICALLY CONSTANT, FOR HIGH TEMPERATURES IT INCREASES AND FOR LOW TEMPERATURES IT DECREASES EVENLY. THE DISCREPANCY OF THERMAL CONDUCTIVITY WAS ESTABLISHED FOR THE FREEZING AND THAWING OF BIOLOGICAL TISSUES. THE THERMAL CONDUCTIVITY OF VARIOUS BIOLOGICAL MATERIALS MAY VARY BY 60% IN TERMS OF MOISTURE CONTENT.
