Calculation of the temperature conductivity of frozen poplar wood during its defrosting. An approach for the computation of the wood temperature conductivity a during defrosting of the wood has been suggested. The approach takes into account the physics of the process of thawing of the ice, which is created in the wood by both the hygroscopically bounded and the free water. It reflects for the first time also the influence of the fiber saturation point of wood species on the value of their a during wood defrosting and the influence of the temperature on the fiber saturation point of frozen and non-frozen wood. For the computation of a according to the suggested approach a software program has been prepared in FORTRAN, which has been input in the developed by Microsoft calculation environment of Visual Fortran Professional. With the help of the program computations have been made for the determination of a of often used in the veneer and plywood production poplar wood with moisture content 0.2 ≤ u ≤ 1.2 kg.kg-1 at the temperature range between -2oC and -60oC during defrosting of the wood.
