We identified 97 strong pulsars from the NRAO VLA Sky Survey ( NVSS ) at 1.4 GHz north of Dec ( J2000 ) > -40 \degr .
The total flux density , linear polarization intensity and polarization angle ( PA ) of all pulsars are extracted from the NVSS catalog .
The well-calibrated PA measurement of 5 pulsars can be used for absolute PA calibrations in other observations .
Comparing the source positions with those in the pulsar catalog , we got the first measurement of the proper motion upper limit of PSR B0031 - 07 , which is \mu _ { \alpha } \cos \delta = -102 \pm 74 mas yr ^ { -1 } and \mu _ { \delta } = -105 \pm 78 mas yr ^ { -1 } .
