AbstractOne large glitch was detected in PSR B1737-30 using data spanning from MJD 57999 to 58406 obtained with the newly built Shanghai Tian Ma Radio Telescope (TMRT). The glitch took place at the time around MJD 58232.4 when the pulsar underwent an increase in the rotation frequency of Delta nu about 1.38x10(-6) Hz, corresponding to a fractional step change of Delta nu/nu similar to 8.39 x 10(-7). Post-glitch nu gradually decreased to the pre-glitch value. The frequency derivative was observed to undergo a step change of about -9x10(-16) s(-2). Since July 1987, there have been 36 glitches already reported in PSR B1737-30 including this one. According to our analysis, the glitch size distribution is well described by a power law with an index of 1.13. The distribution of the interval between two adjacent glitches (waiting time Delta T) follows a Poisson probability density function. For PSR B1737-30, the interval is prone to be long after a large glitch. However, no correlation is found between glitch size and the interval since the previous glitch.
