Highly accurate binary-pulsar timing plays an important role in test ofGeneral Relativity. In this Letter, we argue that PSR J0337+1715, amilli-second pulsar in a stellar triple system, could be a very good laboratoryfor testing the strong equivalence principle (SEP). From the reported orbitalparameters of this triple system, we give an uplimited estimation of theNordtvedt parameter $\eta_\text{N} < 10^{-4}$ based on the orbital polarizationcalculation. This result is slightly better than the existed ones. In addition,if based on the observed uncertain value of inner orbital eccentricity, we evencan obtain $\eta_\text{N}$ up to $10^{-7}$, which needs to be confirmed infuture. However, more rigorous and accurate measurement of the Nordtvedt effectshould be taken from more timing data of PSR J0337+1715.

PSR J0337+1715: an appropriate laboratory for testing the Nordtvedt effect
