Kinematical Properties of Planetary Nebulae with WR-type Nuclei
  We have carried out integral field unit (IFU) spectroscopy of H$\alpha$, [N
II] and [O III] emission lines for a sample of Galactic planetary nebulae (PNe)
with Wolf-Rayet (WR) stars and weak emission-line stars (wels). Comparing their
spatially-resolved kinematic observations with morpho-kinematic models allowed
us to disentangle their three-dimensional gaseous structures. Our results
indicate that these PNe have axisymmetric morphologies, either bipolar or
elliptical. In many cases the associated kinematic maps for the PNe around hot
central stars also reveal the presence of so-called fast low-ionization
emission regions.
