诊断技术的实施必须有相应的仪器和系统来保证，仪器和系统的合理选用是诊断工程技术中的关键问题之一。本讲介绍振动仪器和系统的性能、特点和应用场合。 随着大规模工业生产的发展，设备日趋复杂、精密，对监测诊断的仪器和系统提出了更高的要求。而目前信息工程领域软硬件的
The implementation of diagnostic techniques must be accompanied by appropriate instruments and systems to ensure that the proper selection of instruments and systems is one of the key issues in diagnostic engineering. This talk introduces vibration instruments and system performance, features and applications. With the development of large-scale industrial production, the equipment is more and more complicated and sophisticated, putting higher requirements on the instruments and systems for monitoring and diagnosis. The current information engineering hardware and software
