In 1980, the research program in pH was re-established at the National Bureau of Standards (NBS). This report describes the state of this research, as well as the state of the NBS pH standards. The thermodynamic definition and the determination of pH are elaborated. The problems of liquid junction potentials encountered in the practical determination of pH are discussed. The goal of the research program in pH is to develop and maintain a unified pH scale based on clearly stated thermodynamic criteria, with a wide range of applicability to practical pH measurements.
1980年，国家标准局（NBS）重新设立了pH值研究项目。本报告描述了该研究的现状以及NBS pH标准的现状。阐述了pH值的热力学定义和测定方法。讨论了实际测定pH值时遇到的液接电位问题。pH值研究项目的目标是基于明确的热力学标准制定并维持一个统一的pH标度，使其广泛适用于实际pH测量。
