A bstract When a wide range of temperatures is considered, difficulty is encountered in accurately representing the thermal conductivity of any material, the temperature‐conductivity function of which is not a straight‐line relation. This difficulty can be obviated by use of the “true” conductivity function as defined herein. The use of the “true” conductivity function confers the additional advantage that it makes possible a graphical method for the calculation of heat transmission through compound structures, under conditions of equilibrium heat flow. Though this is still a trial‐and‐error process, from the theoretical viewpoint it is more sound and from the practical angle more easily usable than the arithmetical method generally employed heretofore. The new method is illustrated by the solution of a typical problem.
