摘要
本文在论述测试技术对于航空科技发展的重要作用的基础上，较全面地介绍了国内外多点压力测量技术、设备的发展和现状，概要介绍了近十余年在国际市场上出现的７８０Ｂ、ＺＯＣ、ＨｙＳｃａｎ２０００、８４００等压力测量系统的工作原理、结构特点和主要性能。同时，也介绍了由西北工业大学所研制的ＥＳＰＭＳ、ＤＳＹ６４以及ＤＳＹ１２８等三种电子扫描压力测量系统的特点和性能。
Based on the dissension of significant affect of measurement technique on the aeronautica 1 science and technology deyelopment, the history and current situation of multipoint pressure technology and equipment are introduced completely in this paper. The operating principle,configuration and main function for 780B, ZOC, HyScan2000 and 8400pressure system,which appear in the international market nearly ten years ago, are given in the paper too. The electronic scanning pressure systems ESPMS,DSY64 and DSY128,deyeloped by the Northwestern Polytechnical University,a lso presented.
