摘　　要：射流管与偏转板射流液压放大器的模型对射流型电液伺服阀的性能仿真、设计和使用至关重要。虽然,目前还没有准确的数学模型能够对其性能进行描述,但是有大量的近似模型可供使用。为给射流型电液伺服阀的设计提供一定的理论指导,介绍了六个具有代表性的模型,并对这些模型的应用条件和范围进行了阐述。The models of jet-pipe and deflector-jet hydraulic amplifier are very important and necessary for the simulation,design and application of the jet-type electro-hydraulic servovalve( including jet-pipe servovalve and defelctor-jet servovalve). Although there is no accurate mathematical model to describe their performances,a large number of approximate models are available. In order to provide a theoretical help for the design and simulation of the jet-type electro-hydraulic servovalve,six models are introduced in this paper,and the application conditions of these models are also introduced.
