摘要：

Violation of the Gottfried sum rule was suggested by the New Muon Collaboration in measuring proton and deuteron F-2 structure functions. The finding triggered many theoretical studies on physics mechanisms for explaining the antiquark flavor asymmetry (u) over bar - (d) over bar in the nucleon. Various experimental results and proposed theoretical ideas are summarized. Possibility of finding the flavor asymmetry in :Drell-Yan experiments is discussed together with other processes, which are sensitive to the (u) over tilde/(d) over bar asymmetry.
