摘要：
I compare the lattice calculation of Fukugita et al. for the pion S-wave scattering lengths to the predictions of Chiral Perturbation Theory to two loop accuracy. I comment on the use of this comparison to extract the Chiral Perturbation Theory low energy constants. (C) 1997 Published by Elsevier Science B.V.
