摘要：
Observed line profiles in the high and low states for NGC 5548 and 3C 390.3 are compared to theoretical line ratios. The two objects show different velocity dependencies of line ratios, indicating different contributions of the disk component as a function of velocity. Even though both objects are different, the broad line regions can be represented by a two-component model.
