Study of the C IV ($\lambda\lambda$1548.187 - 1550.772), Si IV   ($\lambda\lambda$1393.755 - 1402.770) and O IV ($\lambda$1401.156) Regions of   the QSO J021327.25-001446.93
  Broad Absorption Line Regions - BALR are composed of a number of successive independent absorbing density layers. Using the GR model, we analyze the UV Si IV ({\lambda}{\lambda}1393.755 - 1402.770), O IV ({\lambda}1401.156) and C IV ({\lambda}{\lambda}1548.187 - 1550.772) resonance lines in the spectra of a certain QSO and discuss the results concerning its kinematic properties (rotational, radial and random velocities).
