In particular, recent progress on the u-bar/d-bar asymmetry is explained. Then, we discuss possible future experimental studies. 1. Introduction 2. Present situation 3. Future u-bar/d-bar asymmetry studies 3.1 Drell-Yan process 3.2 Charged-hadron production 3.3 W charge asymmetry 3.4 Deuteron acceleration at HERA1+6 pages, LATEX2e. Talk given at the International Workshop on Exciting Physics with New Accelerator Facilities, Spring-8, Nishi-Harima, Japan, Mar.11-13, 1997.
