1973年8月在杨州师范学院化学系实验工厂、上海电工仪器厂、长城电工仪器厂、陕西省计量局、甘肃省计量管理处,以及中国计量科学研究院的参加下,对53个国产高精度标准电池进行了性能试验,并在温度10～30℃范围内测定了它们的温度系数,同时也测定了滞后效应、放电后的恢复能力等特性。试验结果,全部标准电池的滞后效应小于2微伏,放电后的恢复能力小于2微伏,达到了对高精度标准电池的性能判别要求。在测定标准电池的温度系数时,是在10、15、20、25、30℃时进行的,所测得的数据,经过数学处理后,得出温度系数列于
August 1973 in Yangzhou Teachers College Department of Chemistry Experimental Factory, Shanghai Electrical Instrument Factory, the Great Wall Electrical Instrument Factory, Shaanxi Provincial Bureau of Metrology, Metrology Administration of Gansu Province, and China Institute of Metrology, the 53 domestic high Accuracy standard batteries were tested for their performance and their temperature coefficients were measured at temperatures ranging from 10 to 30 ° C. Hysteresis and recovery after discharge were also measured. The test results show that the hysteresis effect of all the standard batteries is less than 2 microvolts, and the recovery capability after discharge is less than 2 microvolts, achieving the performance discrimination requirement for high-precision standard batteries. In the determination of the temperature coefficient of standard batteries, it is carried out at 10,15,20,25,30 ℃, the measured data, after the mathematical treatment, the temperature coefficient was listed in
