摘　　要：经常使用的玻璃电极要保持湿放 ,但长期的湿放会对电极的响应产生不良影响。利用 5 %的氢氟酸对电极进行表面处理 ,对电极的玻璃系统的化学稳定性进行了测定 ,并在理论上加以分析 ,证明用酸抛光法对玻璃电极表面进行处理 。The glass electrode frequently used should be kept in soak solution,but its performace is deterioated in long time soaking. We have eliminated this effect by acid polishing the glass electrode surface with HF(5%). Its validity for restoring the electrode performance is verified by measuring the chemical durability. We have also proved it theoretically.
