A new four-terminal-pair bridge, capable of achieving a relative standard uncertainty of 1×10, was constructed at the National Institute of Standards and Technology by converting a two-terminal-pair bridge. The conversion requires only the addition of components which are easily removed if two-terminal-pair measurements are to be made. The design and testing of this bridge is described. The new four-terminal-pair bridge requires fewer auxiliary balances than the present four-terminal-pair bridge employed at NIST, which makes it much easier to use. This new design can be used to compare capacitance, resistance, and inductance standards.
美国国家标准与技术研究院通过改造一个双端对电桥，构建了一种新型四端对电桥，其相对标准不确定度可达1×10 。这种改造仅需添加一些组件，如果要进行双端对测量，这些组件很容易拆除。本文描述了该电桥的设计与测试。新型四端对电桥所需的辅助平衡装置比美国国家标准与技术研究院目前使用的四端对电桥更少，这使得它更易于使用。这种新设计可用于比较电容、电阻和电感标准。
