The soil on the structure can be regarded as colloidal capillary-porous body. Its top-tion layer is usually loosened and has a lumpy texture. The chemical composition of different soils varies and is determined by the ratio between the organic and mineral soil. In various soils, this ratio is changed: for the organic part of 10 to 63% and the mineral portion of 37 to 90%. Soil colloids can form colloidal humic substances mikroorganiz-Mami, silicic acid, iron oxide, alumina (aluminum oxide), the finest sand and clay. Since the soil are capillary-porous bodies, the heat transfer in them by means of conduction through the skeleton of the porous body and vnutriporoznogo substance. In wet bodies, which include the ground, accompanied by a heat mass exchange. The temperature gradient gives rise to the potential gradient material, since the latter depends on the temperature. Thermal conductivity coefficient of a two-component system solid particles dispersed - air or particulate matter - water is almost independent of temperature because the thermal conductivity of air and water with increasing temperature increases slightly.
