Abstract. Up to November 2022, 267 pulsars have been discovered in 36 globular clusters (GCs).&xD;In this paper, we present our studies on the distribution of GC pulsar parameters and the detection efficiency. The power law relation between the average of dispersion measure ($overline{rm DM}$) and dispersion measure difference ($Delta {rm DM}$) of known pulsars in GCs is $lgDelta {rm DM} propto 1.52 lg overline{rm DM}$. The sensitivity could be the key to find more pulsars. As a result, several years after the construction of a radio telescope, the GC pulsar number will be increased accordingly. We suggest that currently GCs in the southern hemisphere could have higher possibilities to find new pulsars.&xD;
