  The rotating radio transients are sporadic pulsars which are difficult to
detect through periodicity searches. By using a single-pulse search method, we
can discover these sources, measure their periods, and determine timing
solutions. Here we introduce our results on six RRATs based on Parkes and Green
Bank Telescope(GBT) observations, along with a comparison of the spin-down
properties of RRATs and normal pulsars.
