英文摘要	The five-hundred-meter aperture spherical telescope (fast) will begin its early-science operations during 2016. drift-scan pulsar surveys will be carried out during this period using an ultra-wide-band receiver system (covering similar to 270 to 1620 mhz). we describe a method for accounting for the changes in the telescope beam shape and the pulsar parameters when searching for pulsars over such a wide bandwidth. we applied this method to simulated data sets of pulsars in globular clusters that are visible to fast and found that a representative observation would have a sensitivity of similar to 40 mu jy. our results showed that a single drift-scan (lasting less than a minute) is likely to find at least one pulsar for observations of four globular clusters. repeated observations will increase the likely number of detections. we found that pulsars in similar to 16 clusters are likely to be found if the data from 100 drift-scan observations of each cluster are incoherently combined.
