These, classified as 'post burst decrease' or 'absorption', are gradual phenomena and the duration is usually more than an hour. In contrast to these phenomena, the authors found two sudden decreases of the total flux just before the bursts of July 21, 1978 and September 7-8, 1978. The durations were shorter than 10 minutes. The observational results are given which were obtained by four microwave polarimeters and two interferometers at Toyokawa. A preliminary interpretation is also given for the event of September 7-8, 1978 using the data of optical, soft X-ray and meter-wave observations.}, pages = {53--65}, title = {SUDDEN DECREASE OF MICROWAVE SOLAR RADIO EMISSION}, volume = {26}, year = {1979} }
