1984年1月—1985年6月,笔者应Greg M.Anderson教授之邀访问了加拿大多伦多大学地质系,围绕K_2O-Na_2O-Al_2O_3-SiO_2-H_2O体系的有关热力学问题进行研究,并先后对加拿大、美国、英国、比利时、法国的十二所大学与研究构造进行了短期访问,所作的学术报告,涉及高温高压溶液化学以及环境物理化学的有关课题。这次旅行,使笔者有幸窥视了当代溶液地球化学发展的一个侧面。
From January 1984 to June 1985, at the invitation of Prof. Greg M. Anderson, the author visited the Department of Geology, University of Toronto, Canada, and carried out a research on the thermodynamics of K 2 O-Na 2 O-Al 2 O 3 -SiO 2 -H 2 O system. Twelve universities in the United States, Britain, Belgium and France conducted short-term interviews with research structures and delivered academic reports on topics related to high temperature and high pressure solution chemistry and environmental physics and chemistry. The trip, so I have the privilege to peep the contemporary solution of one aspect of geochemical development.
