| Abstract: | Conclusions Our survey indicates that diverse fine structure is an important (and frequently decisive) property of many radio bursts. As far as we can judge from the available data, however, this type of structure is hardly observed in every phenomenon. One of the major tasks for future research, therefore, is to determine the specific conditions over the active regions that result in the appearance of particular types of fine structure.In particular, the solution of this problem calls for combining observations with a high degree of time and frequency resolution with instrument observations with high angular resolution, which are capable of localizing sources of fine structure within the limits of burst generation regions.Information on the specific conditions under which fine structure arises will help to formulate more definite opinions about possible generation mechanisms both of the fine structure itself and of the associated radio bursts. This information is also necessary in order to link conceptions of radio-burst fine structure with the overall development pattern of solar activity and, in particular, with the phenomena that accompany bursts as a whole.Institute of Terrestrial Magnetism, the Ionosphere, and Radio Wave Propagation, Academy of Sciences of the USSR.
