§1 应用玻璃电极测量pH值的基本方法图(1)中的玻璃容器中部,熔有以特殊玻璃制成的薄膜,薄膜两侧注有不同pH值的溶液,其中并浸有同式的甘汞电极。将二甘汞电极与高度灵敏的测量仪器联接,即可测得两端间有确定的电位差存在,且这电位差随两侧溶液pH的差别而变化。这只能解释为在玻璃薄膜两侧与 §1 The basic method of measuring the pH value of the glass electrode Figure (1) in the middle of the glass container, melted with a special glass film, film on both sides of the injection of different pH solution, which was immersed in the same type of sweet Mercury electrode. By connecting the calomel electrode to a highly sensitive measuring instrument, there is a defined potential difference between the two ends, and this potential difference varies with the pH of the solution on either side. This can only be explained by the glass film on both sides
