Evidence for quasar outflows can be detected via blueshifted broad absorption lines (BALs) in rest-frame ultraviolet spectra of quasars. We have identified 18 narrow absorption line (NAL) systems in the BAL system of SDSS J010612.22+001920.1, indicating that this BAL outflow has achieved a high degree of clumpiness. Moreover, these NAL systems are highly structured in velocity space and separated from each other by the doublet spacings of multiple ionic species, including a sequence of 10 C iv doublets that form arithmetic progression with a common difference of ≈498 ##IMG## [http://ej.iop.org/images/2041-8205/895/2/L44/apjlab9303ieqn1.gif] {$\,\mathrm{km}\,{{\rm{s}}}^{-1}$} . Cases like J010612.22+001920.1 offer strong evidence for the dynamical process of radiative acceleration in quasar outflow, and open up a new way for the research of quasar outflow under the framework of the NAL complex.

SDSS J010612.22 + 001920.1中的高度结构化类星体流出

类星体流出的证据可以通过类星体的静止帧紫外线光谱中的蓝移宽吸收线（BAL）来检测。我们已经在SDSS J010612.22 + 001920.1的BAL系统中确定了18个窄吸收线（NAL）系统，这表明该BAL流出已达到高度结块。此外，这些NAL系统在速度空间中具有高度结构化，并通过多种离子物种的双峰间距相互隔开，包括一系列形成算术级数的10 C iv双峰序列，其共同差值为≈498## IMG ## [ http://ej.iop.org/images/2041-8205/895/2/L44/apjlab9303ieqn1.gif] {$ \，\ mathrm {km} \，{{\ rm {s}}} ^ {-1 } $}。诸如J010612.22 + 001920.1这样的案例为类星体外流中辐射加速的动力学过程提供了有力的证据，
