摘要：

The evolution of Gamma Ray Bursts (GRB) spectra of the events with soft absorption components show a surprising uniformity: spectra always evolve from a strong absorption to a fainter one, which finally may disappear at all. This behaviour is difficult to interpret in a cyclotron model, but is naturally explained in a model of absorption in the expanding cloud, where heavy elements - products of nuclear fission-produce the observed absorption lines.
