北京铀矿选冶研究所研制成GD-Ⅱ和GD-Ⅳ型固态参比电极,于1984年12月26日在核工业部矿冶局组织的鉴定会上通过鉴定,应邀参加本次鉴定工作的有来自九省市28个单位的教授、学者,专家40多位。鉴定会首先听取了研制单位、试用单位和鉴定测试小组分别对研制、使用情况和测试结果所作的报告。与会代表一致认为铀矿选冶研究所研制成的这两种电极,经过实践和测试证明能够耐130℃温度和100公斤/厘米~2的压力,具有机械强度
Beijing Uranium Institute of Mining and Metallurgy developed into GD-Ⅱ and GD-Ⅳ type solid-state reference electrode, on December 26, 1984 at the Ministry of Nuclear Industry Identification Bureau Metallurgical Bureau identified by the invited invited to participate in this appraisal There are more than 40 professors, scholars and experts from 28 units in nine provinces and cities. Identification will first listen to the development unit, the trial unit and the identification of the test group, respectively, on the development, use and test results made by the report. The participants agreed that the Institute of Uranium Mining and Smelting Institute developed these two electrodes, after practice and testing proved to be able to withstand 130 ℃ temperature and 100 kg / cm ~ 2 pressure, with mechanical strength
