  With a direct demodulation method, we have reanalyzed the data from
COMPTEL/CGRO observation of PKS0528+134 during the 1993 March flare in
gamma-rays. Our results show that during the flare gamma-rays were detected at
a level approximately 2.4-3.8 times greater than the observed intensity in two
earlier COMPTEL observations VP 0 and VP 1 in the energy range 3 MeV to 30 MeV.
The 3-30 MeV time variability of the flux follows well the trend as observed by
EGRET/CGRO at higher energies. No convincing excess can be found around the
position of PKS0528+134 in the energy range 0.75 MeV to 3 MeV, which indicates
a spectral break around 3 MeV. The detections and non-detections in the four
standard COMPTEL energy bands are consistent with the earlier reports given by
Collmar et al., while the feature that gamma-rays of the quasar still kept on
flaring at energies down to 3 MeV is clearly found.
