Heat conduction with variable heat transmission coefficients

An analytical method is shown for determining the temperature field of a body whose variable thermophysical properties are functions of the space coordinates. The problem is solved for a plate and for a cylinder where the thermal conductivity is an exponential function of one space coordinate.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 25, No. 2, pp. 353–362, August, 1973.
