内容記述 | The occurrence frequency distributions as a function of the peak intensity (intensity distribution) and the directivities of the simple impulsive bursts (SD type) and of the long-enduring bursts (LE type) have been investigated at 1000, 2000, 3750 and 9400 MHz, following the method of Akabane's analysis (1956). Intensity distributions f (I) of SD bursts are represented by f(I) ∝I^1.8 where I is the peak intensity of a burst, and the directivities are similar at four frequencies. Assuming that the directivity is due to the absorption of a layer over the source of SD burst, it may be considered that the effective height of the source of SD burst decreases with frequency. The occurrence frequency distributions of SD bursts as a function of their degree of polarization and the center-to-limb variations of the degree of polarization of SD bursts have also been investigated. At higher frequencies, the center-to-limb variations of the degree of polarization are very small. LE bursts at 3750 and 9400 MHz show high directivity (Dodson et. al., 1954). LE bursts of high flux ratio have higher directivity, where the flux ratio is Flux3750/Flux9400. | |||||
