摘要

I first met Don Helmberger when I visited Caltech in the spring of 1984 as a prospective graduate student.During that visit,I was immediately impressed by Don's unbridled passion for science,in general,and seismology,in particular.Don made me feel quite at ease as we discussed mantle triplications,core phases and ray theory.
