The phenomenon of pulse nulling was first found by Backer (1970). The fraction of time, we denote it by n(%), for a pulsar in a null state was given by Ritchings (1976) for 32 pulsars. We have found that the average value of n(%) increases with the period of pulsars. It perhaps implies that the pulsars with pulse nulling could constitute a subtype of pulsars. In this paper, the pulsars with pulse nulling are regarded as a subtype to be investigated.
