英文摘要	We presented timing results of PSR B2035+36 using similar to 9-yr observations with the Nanshan 25-m radio telescope. PSR B2035+ 36 was reported to exhibit significant changes in pulse profile correlated with spin-down state variations. We found that the pulsar underwent a glitch with a jump in frequency of Delta nu similar to 12.4(5) nHz around MJD 52950. Unusually, the spin-down rate increased persistently over 800 d after the glitch, and the average spin-down rate postglitch was about 9.6 per cent larger than that pre-glitch. After the glitch activity, the pulse profile became narrower and the pulsar began to switch between two emission modes, with pulse widths (W-50mean) of 8.5(7)degrees and 3.7(3)degrees, respectively. In addition to that, the relatively narrow pulse profile gradually became dominant. All of the observations indicate that there should be a connection between magnetospheric behaviour and glitch activity. We discuss one possibility of magnetosphere fluctuation triggered by the glitch event.
