摘要：
The future use of space-borne IR spectroscopy to determine the ionization structure and abundances in the outer winds of WR stars is described. A mass loss rate of 1.7 x 10(-5) M.yr-1 has been derived from 10-mu-m photometry of the WO2 star Sanduleak 5 (WR 142). The He/H number ratios in the winds of P Cyg and AG Car have been derived from a recombination line analysis of their 1-4-mu-m spectra and mass loss rates of 2.2 x 10(-5) M. yr-1 and 3.7 x 10(-5) M. yr-1 have been respectively derived for them.
