一、概述 设备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。本文就振动仪器和系统的性能、特点、应用场合等作一归纳性介绍，供读者参考。 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更 First, an overview of equipment diagnostic techniques must have the appropriate equipment and systems to ensure. The proper selection of instruments and systems is one of the key issues in diagnostic engineering. In this paper, the performance of vibration instruments and systems, features, applications, such as induction for a brief introduction, for readers reference. With the development of large-scale industrial production, the equipment has become increasingly sophisticated and sophisticated, and more advanced equipment and systems for monitoring and diagnosis
