Megamaser emission of galaxies in the OH main lines 1665 and 1667 MHz /see, e.g., Baan, 1989/ is analysed. A semi-analytical time-dependent solution is obtained of a system of differential equations which includes the radiative transfer equation and the equation for population difference of the maser levels. The system was solved by the Euler's method. Various cases of solution perturbations, caused by time variability of the central radio continuum source are considered.
