Abstract
The paper is devoted to the application of the variational approach to the radiative transfer problems in the one-dimensional case. To this end the results of the rigorous mathematical theory are used. It is sh own that the conservation law due to the form-invariance of Lagrangian with respect to the axes translation transformation entails both the Ambartsumian's invariance principle and Rybicki's quadratic relations.
