　　Time：April 3-4, 2004

　　Introduction：1st and 2nd China-Japan Joint Seminars on Separation Science were held in Dalian, China on July 2000 and in Kyoto, Japan on December 2001, respectively. The two seminars have made great progress in separation science as well as the relationship between both sides. On the basis of last two seminars, we plan to hold the 3rd China-Japan Joint Seminar on Separation Science in Dalian, China during April 2-4, 2004. The aim is to provide a forum for discussion and interaction between the pioneers involved in the groundbreaking work of past decades and those young scientists who are bringing into important play in the new century.
