摘要：

It is shown that gas clouds in a biconical shape may produce profiles similar to those produced in a spherical geometry. The profile shape depends on the radial velocity field, the projection angle, and most importantly, the shell luminosity distribution. If the conical region extends over a large range of radial distance, the resultant profile may be symmetrical with logarithmic wings, otherwise apparent may be observed. It is shown that the double-peaked Hβ profile in Akn 120 can be modeled with a double-stream model.
