Abstract A new fact concerning this relation is presented. The traveling time (DELTA T), from the sun to the earth, of flareassociated low-energy cosmic rays as a function of the heliographic longitude of corresponding flares implies that the propagation mechanism is not related to the state of interplanetary space. Next the relation of smoothed flux intensity and duration of solsr radio waves at (a) 3000 Mc/s and (b) 200 Mc/s was plotted. The plot indicates that (1) there is no relation between the separation in traveling time and the duration of solar radio emission at either frequency and (2) the separation closely correlates to the flux intensity of 3000 Mc/s radio waves. Another figure showing the relation between DELTA T and the flux intensity for 3000 and 200 Mc/s radio emission indicates a close connection between the low-energy solar cosmic-ray generation and solar radio emission. From these figures several conclusions are drawn. The ejection and propagation mechanism of cosmic rays in interplanetary space is also discussed.
