From the Preface: "The research on BIE-BEM in China and Japan had been started almost about the same time in the late seventies. A bilateral exchange program for sponsoring the Joint Symposiums on BEM between the two countries had been planned in 1985. Then the first Japan-China symposium on boundary element methods had been held in Karuizawa, Japan, June 1-5, 1987. The present proceedings volume of this second symposium held in Beijing in October 1988 contains technical papers of BIE-BEM from Chinese and Japanese authors on various aspects of BEM."
