由英国流体力学研究协会负责组织的第十届国际流体密封会议于1984年4月在奥地利因斯布鲁克会议中心举行。会议宣读的36篇论文中有13篇是关于机械密封方面的论文。从这些论文中可以看出目前世界上机械密封研究开发的主要动向。本文着重讨论了基础理论研究以及基础性试验研究方面的发展动向。 The Tenth International Fluid Seals Conference, organized by the British Society of Hydrodynamics, was held in April 1984 at the Innsbruck Congress Center in Austria. Thirteen of the 36 papers presented at the conference were papers on mechanical seals. From these papers, we can see the main trends in the research and development of mechanical seals in the world at present. This article focuses on the development of basic theoretical research as well as basic experimental research.
