The generation of solar millisecond spikes on the maser cyclotron resonance is studied by taking into account the large-scale monotonic magnetic field inhomogeneity and the small-scale plasma inhomogeneity. It is shown that the presence of these inhomogeneities can have a significant effect on the generation of electromagnetic waves. In this case the structure of the inhomogeneities determines the spectral and temporal parameters of emission. A modeling of the spike dynamic spectrum in the presence of a small-scale inhomogeneity of coronal plasma is performed. It is shown that a simple model of the plasma inhomogeneity (traveling density wave) can account for many of the observed features of spikes.
