摘　　要：我国高档密封件与液压件产品几乎全部依赖进口,国家重大技术装备及国防装备等配套零部件行业的许多问题与摩擦学有十分重要的关系,基础件摩擦学又是国际上的研究热点与发达国家的竞争高地.在本文中阐述了国内外关键机械零部件的接触界面原位在线测试的研究进展,及其在大变形软材料密封系统中的应用,综述了摩擦润滑中迁移状态实时在线观测技术、聚合物密封界面在线观测技术和国内在摩擦过程的微区域原位研究等进展,还分析了特殊与极端工况条件下大变形聚合物密封的性能测试、可靠性寿命分析以及多工况联合测试的技术进展,分析和讨论了高性能密封件行业的基础共性难题,最后进行了总结与展望.When considering the achievement of national economic growth and human life,rubber figures as one of the most important raw materials.The conventional use of rubber is mainly manufacturing tires employed by various vehicles and airplanes,while the automobile and aircraft industry are the pillar industries of the national economy in many countries.As a kind of high elasticity materials,rubber has some favorable properties(such as wearability,low vibration and noise,oil-resistance),which are not possessed by metals and other polymer materials.In view of the engineering application,rubber tribology is of importance.Nowadays,the contact of two surfaces is a common phenomenon in nature and industry.A contact system includes material with the very low elastic modulus,e.g.rubber,is generally known as soft contact.Soft contacts are present in many practical engineering and biological applications,including tire,sealing ring,windscreen wiper,water lubricated bearings,contact lens,tongue-palate contact,micro/nano fluidic devices,and polishing pad in Chemical Mechanical Polishing(CMP).In soft contact,the contact pressure is great enough to cause large elastic deformation of one or both of the interacting solids,which would lead to the instability and nonlinear behavior at contact interface.As an example,there have been many attempts to explain the proportionality between the applied load and the worn surface.In the last decades,a great deal of tribological experimental and numerical works has carried out to understand the underlying mechanisms governing the frictional properties of rough soft contact in many applications,such as the rubber seals,grip of tires,synovial joints,and windscreen wipers.Each application would benefit from a specific result.In addition,since the tribology of basic-parts for major equipment is an important growing interdisciplinary area,the developing of rubber and its products as well as tribology will certainly simulate its growing and increase demand for information in this field.Tribology of bas
