摘　　要：在对美国Cortest公司设计的Ag/AgCl参比电极进行改进的基础上,采用电解法制备了一种内置式Ag/AgCl参比电极,对其进行了性能测试,并用其对油管钢N80的高温高压腐蚀行为多次进行了测试研究.结果表明,该参比电极具有重现性好、可逆性好、响应时间短、内阻小等优良性能,且在高温高压条件下工作性能稳定,测试曲线理想,可用于高温高压电化学研究.On the basis of the improvement of Ag/AgCl reference electrode of Cortest Company in America, the internal Ag/AgCl reference electrodes were prepared by means of electrolyzing. Their features were tested and the corrosion behavior of tubular steel N80 under high temperature and high pressure were studied with them. The results show that it has such outstanding features as good reproducibility and reversibility, short response time and small resistance. The new electrodes worked stably and ideal test curves were obtained under high temperature and high pressure, and could be used in electrochemical research under high temperature and high pressure.
