摘要
The stability of the integrated profile of PSR B0329 + 54 at 1,540 MHz is studied with the observation data of the Nanshan 25-m radio telescope of up to 453 hr from 2003 to 2009. We find that the profiles of two modes tend to stabilize at a faster rate first, then change to a slower rate, and then become rapidly stabilized again. It is also shown that there are distinct differences in the profile stability behaviors on the short, intermediate, and long timescales. Our results will be valuable for future research on random processes in pulsar radio radiation.
