Results are presented for high-resolution spectral polarization observations of the sun in the wavelength range from 2 to 9 cm. Dynamic spectra are obtained for two local sources of the S-component of unpolarized solar radio emission. It is found that the nature of the spectra changes during development of the local sources and that these changes, which occur primarily in the longwave part of the spectra (6 to 9 cm), are associated with changes in the structure of the sunspot groups corresponding to the local sources. The spectrum of the polarized emission from the examined local sources is found to have a well-expressed maximum near 3 cm. It is shown that the dimensions of the unpolarized-emission sources vary with wavelength, monotonically increasing by a factor of three in the range from 2 to 9 cm. A thermal nature is postulated for the local-source emission. The electron-temperature height distribution in the local sources is determined by assuming that the emission is caused by the simultaneous action of bremsstrahlung and magnetic bremsstrahlung mechanisms as well as by interpreting the observational results in terms of a dipole model for the sunspot magnetic field.
