Model calculations are used to study observed variations of column density and X-ray luminosity as a function of orbital phase. The models include a spherically symmetric stellar wind, and the wind plus three types of gas streams. The comparisons of the models with the data by least-squares fitting demonstrate that a gas stream is a necessary part of the models. A gas stream in systems like GX301-2 may be expected, based on the results of Stevens' model of enhanced stellar wind accretion for eccentric X-ray binaries.
