One 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 1.38 \times 10 ^ { -6 } Hz , corresponding to a fractional step change of \Delta \nu / \nu \thicksim 8.39 \times 10 ^ { -7 } .
Post - glitch \nu gradually decreased to the pre - glitch value .
The frequency derivative was observed to undergo a step change of about - 9 \times 10 ^ { -16 } s ^ { -2 } .
Since July 1987 , there are 36 glitches already reported in PSR B1737 - 30 including this one .
According to our analysis , the glitch size distribution is well described by the power law with index of 1.13 .
The distribution of the interval between two adjacent glitches ( waiting time \Delta T ) follows a Poissonian probability density function .
For PSR B1737 - 30 , the interval is prone to be long after a large glitch .
But no correlation is found between glitch size and the interval since previous glitch .
