摘要
The calorimetric method was applied to determine the internal heat source capacity in frozen and dried layers of freeze-dried random solids. The linearly approximated form of the dissipation coefficient as a function of temperature was derived. Two estimated coefficients in this dependence are sufficient to include effects of generation and absorption of microwave energy in a dried material.
