Factors that could produce the statistical relationship observed between the duration of transient processes on the Sun and the power of corresponding disturbances of the interplanetary medium are investigated. Uniform data on the soft X-radiation of more than 50000 flares made it possible to study their number distribution according to duration in four ranges of event power. It proved possible to identify three event types: impulse flares of a total duration of less than 30 min, typical (two-ribbon) flares of less than one to two hours' duration, and very prolonged events, which include phenomena in activity complexes and dynamical flares. These results are in good agreement with the expected phenomena durations, which were determined from the energy balance in the flare source of the soft X-radiation. In particular, while there is a free leakage of the generated hot plasma in impulse flares, heating near a coronal-loop apex becomes significant in two-ribbon flares and determines the entire process in prolonged flares. A comparison of the data on soft and hard X-rays demonstrated that fairly powerful impulses are as a rule followed by the formation of a coronal-loop system. This process of the formation of a flare-loop system often generates a shock wave, which gives rise to coronal mass ejections (CMEs). The possibility is discussed that, in the most prolonged flares, CMEs often lead to new flare formations, the ejection of material from coronal levels continuing and increasing disturbances in interplanetary space for a lengthy period of time.
