title: [The local and time-dependent temperature field in the body of a homeothermic organism in case of sudden changes of quantity and local distribution of internal heat production (author's transl)].
abstract: For the local and time-dependent temperature field in a homeothermic organism the symmetry of constant mean surface curvature is a geometrical adequate descriptive form. The according form of the partial differential equation of heat conduction with a suitable source function has been solved for sudden changes of the internal heat production. The thermodynamical difference between decrease and increase of the body heat content is discussed. The solution formula is also valid in case of sudden change of heat loss, caused for example by changes of the climatic conditions of the environment, clothing, or wetness of the skin surface. The results of the calculations are in good agreement with experimental data of other authors.
