[en] There are some most interesting analogies between x-ray bursters and novae. Both these phenomena evidently result from nonstable thermonuclear burning of accreted matter. It seems to the authors that the bursters represent the x-ray analogue of recurrent novae, while the transient sources (those displaying no recurrent) would be the x-ray analogue of ordinary novae: when a transient source flares, a massive helium envelope is consumed. Although analysis of thermonuclear burning in neutron-star envelopes has yielded much valuable information for interpretating the burster properties that are observed, there remain many problems calling for further research. Numerical modeling with restricted networks as yet has been unable to reproduce the intricate structure recorded in some bursts, such as those with double peaks. The mechanism of thermonuclear burning in a magnetic column also warrants more careful attention, as a possible model for γ-ray bursters. Finally, the continued refinement of the thermonuclear model will depend crucially on new observational data: more accurate measurements may soon be expected for many of the spectral and time parameters of x-ray bursts
