在10 ° C和50° C下测量了在广泛pH范围内锂和钠水溶液中玻璃电极的误差。并与25° C时的数据进行了比较。碱性误差在较高温度下较大，在较低温度下较小，但酸或水活度误差几乎不随温度变化，这取决于与多尔的“水电极”理论一致，碱性误差随温度增加，雅阁多尔统计方程的要求，然而，“Q”量不是严格恒定的，而是随着pH值、盐浓度和温度而略有变化。这里给出的数据具有实用性，可用作25° C以外温度下玻璃电极测量的校正因子，pH校正表被包括在文件中。
The error of the glass electrode in lithium and sodium aqueous solutions over an extensive pH range was measured at 10 and 50° C. and compared with the data at 25° C. The alkaline error is greater at the higher temperature and less at the lower temperature, but the acid or water activity error scarcely changes with the temperature, depending, in agreement with the "water electrode" theory of Dole, only on the activity of the water at any particular pH. The alkaline error increases with the temperature in accord with the requirements of the statistical equation of Dole insofar as the order of magnitude is concerned; the "Q" quantities, however, instead of being strictly constant, change slightly with the pH, salt concentration and temperature. The data given here have the practical utility of being applicable as a correction factor to glass electrode measurements at temperatures other than 25° C., a pH correction table being included in the paper.
