  Using the modified internal shock wave model we fit the gamma ray burst (GRB)
light and spectral curves of 30 GRBs observed with BATSE. From the best fitting
we obtain basic parameters of the relativistic shells which are in good
agreement with predictions given earlier. We compare measured GRB parameters
with those obtained from the model and discuss connections between them in the
frame of the physical processes laying behind GRB events.
