摘要：

High velocity and massive outflowing winds may be present in most quasars but only detected in those cases where our line of sight intersects the outflowing absorbing stream. We present results from Chandra, Suzaku and XMM-Newton observations of a sample of Narrow Absorption Line (NAL) quasars with high velocity outflows. In contrast to what is found in Broad Absorption Line (BAL) quasars we do not detect any significant excess intrinsic X-ray absorption in NAL quasars, however, we do find a possible correlation between the maximum outflow velocities of the UV absorbers of NAL quasars with the slope of the UV to X-ray continuum. Such a correlation, if confirmed in a larger sample, may provide constraints on the geometry and acceleration mechanism of quasar winds.
