摘要：
We present detailed optical spectrophotometry of 7 galactic WR stars: HD 4004 (WN 5), HD 16523 (WC 5), HD 17638 (WC 6), HD 191765 (WN 6 SB1), HD 192103 (WC 8), HD 192163 (WN 6 SB1), and HD 193928 (WN 6 SB1) based on medium dispersion spectra. Equivalent widths (EW) and full widths at half maximum (FWHM) of almost all lines in the optical region are measured, absolute continua are determined, dereddened line fluxes are presented, the ionization potential vs. 1/2 FWHM graphs are constructed and new, tentative identifications of S VI lines are proposed.
