Abstract: This paper compared the smoothed averages of solar ms-resolution data with s-resolution data of the burst at 2.84 GHz on May 16, 1991 and found that the two kinds of data are not self-consistent, neither in calibration nor trend of burst fluxes. In this paper, using above method, the data of May 16, 1991 are processed and found the ms-resolution records can be reduced to the s-resolution records. The makes it clear that the data with various time constants from the improved receiver in 1990 are self-consistent.In this paper, a band-pass filter is used to separate the components of rapid fluctuations with various time scales from ms-resolution data of solar bursts. Although the components of rapid fluctuations with the time scale lower than 0.1s have not been found in data of May 16, 1991; above method is very useful to examine and processing data in future observations.
