一、引言理想标准的主要要求是时间稳定性和对干扰影响量无关。直流标准的选展不仅通过改进“经典”方法来获得,还要通过利用在测量技术上新的物理发明来获得。下面报告 PTB(西德物理技术研究院)在这些方面的看法。二、电学单位的定义和复现测量学中的法制单位是国际单位制(SI)的基本单位和由此导出的导出单位。在测量技术中
I. INTRODUCTION The main requirement of an ideal standard is that the time stability is independent of the amount of interference. The selection of DC standards is not only achieved by improving the “classic” method, but also by using new physical inventions in measurement technology. The following is a report on PTB (West German Institute of Physical Technology) in these areas. Second, the definition and recurrence of electrical units The legal unit of measurement is the basic unit of the International System of Units (SI) and the derived unit derived therefrom. In measurement technology
