| 作者对9种金属、合金电极在天然海水和四个海区的海底泥中进行了电极稳定性试验,获得了在海水中132d、海泥中280d的电极电位变化数据;并对氯化银及锌合金电极作了加压模拟水深试验。实验表明,海水温度对氯化银及锌合金电极电位影响不大;认为这两种电极作为海洋钢构筑物保护电位水声遥测装置的长效参比电极是适宜的。 |

| INVESTIGATION OF LONG EFFECTIVE REFERENCE ELECTRODE IN SEAWATER AND SUBSEA MUD |
|
|
| Abstract: |
| The stability of nine electrodes exposed to seawater for 132 days and subsea mud for 280 days was being tested. Ag/AgCl electrode potential drifts less than 4mV, Zn alloy electrode potential drifts±20mV. According to our analog testing results, the influence of the water pressure at depth of 300m on electrode potential is slight. The changes of tempreture have also little effect on electrode potentials. thus electrodes of both Ag/AgCl and Zn alloy are considered to be long effective reference electrodes used in acoustic telemetering system for detecting cathodic protection potential of subsea structure. |
