摘要：

The behavior of the velocity projection factor was studied for three individual Lines, He I 4438 Angstrom, Si III 4553 Angstrom, and N II 4442 Angstrom, and for the complete spectrum in the radially pulsating helium rich star V652 Her. It is shown that the projection factor is itself a function of expansion velocity.
