On the Equation of Heat Flux passing across　the Plates having two covered sides

摘要

The approximate equations are found by the use of the function of complex variables，for the heat flux or the quantity of heat passing through the plate having two covered sides per unit area in unit time.The equation is the function of variables such as the thermal resistance，R ，heat capacitance， C， the thermal conductivity， K; and show the amount of heat quantity necessary to sustain the flowing heat sgstem in a constant temperature balancing the escaping heat quantity per unit volume in unit time
