Description:

We present some effects of an increasing He abundance in the stellar atmosphere. The run of b-factors with depth for vatious He abundances is given as well as the theoretical equivalent widths of He I and Balmer lines. The appearance of certain shell lines suggests a strong influence from a circumstellar envelope.
