摘要：

Using a pair of the lightest mirror nuclei, He-3 and H-3, we study the effect of the medium modification of pion fields on the flavor nonsinglet structure function. The change of the pion fields leads to an enhancement of the flavor asymmetry of the antiquark distributions in a nucleus. (C) 2001 Elsevier Science B.V. All rights reserved.
