低温度系数饱和标准电池(以下简称电池)可用作维护和传递电压单位的实物标准器,并作为高精度数字电压表的标准和标准电压源。目前仍使用饱和标准电池来保持电压单位,但这种电池的电动势—温度系数太大,对温度控制的精度要求太高,因而限制了电压标准的保持和传递的准确度。1979年3月,国家低温系数饱和标准电池特性试验小组,对我国生产厂家的57只标准电池进行了全性能试验。本文介绍在饱和标准电池的全性能试验中,温度的精
Low Temperature Coefficient Saturated Standard Battery (hereinafter referred to as Battery) can be used as a physical standard for maintaining and transmitting voltage units and as a standard and standard voltage source for high-precision digital voltmeters. At present, saturated standard cells are still used to maintain voltage units. However, the electromotive force-temperature coefficient of such cells is too large, and the precision of temperature control is too high, thus limiting the accuracy of voltage standard maintenance and transmission. In March 1979, the national low temperature coefficient of saturation standard battery test group, China’s manufacturers of 57 standard batteries for the full performance test. This article describes the full performance of saturated standard batteries in the test, the temperature of the fine
