摘要
从低频和超低频振动测量多个应用领域的角度讨论研究建立低频超低频振动幅相特性计量基标准溯源体系的重要性,介绍国内外研究发展状况,提出低频电压测量的溯源性问题,分析了超低频振动计量基标准实现精确测量的若干关键技术。
As viewed from multiple application fields of low-frequency and super low-frequency vibration measurement, the importance of researching and establishing metrology standards for measuring the low-frequency and the super low-frequency vibration magnitude and phase characteristics. is discussed. The progresses of research at domestic and abroad are introduced. The traceability problem about low-frequency voltage measurement is presented. Some key technologies to realize exact measurement are analyzed.
