【摘要】 用氢电极-银/氯化银电极无液接界电池法测量由酸性至偏碱性（pH1～9）四种标准溶液100～150℃的pH_?值。建立水溶液100～150℃的pH标度,总的不确定度在±0.04pH以内,并与国外的有关工作进行了比较。更多还原

【Abstract】 This paper describes the establishment of pH scale of aqueous solution at elevated temperature 100 to 150℃. In this work, the method of hydrogen electrode—silver/ silver chloride electrode without liquid junction cell has been used for determining the pH_s of four standard solutions, which contains pH ranging from 1 to 9.The total uncertainty is ±0.04pH.The comparison between our results and others is also given.更多还原
