摘　　要：本文应用可以测出钢的瞬时腐蚀速度的腐蚀电化学科化电阻技术，及XRD和SEM方法，研究了左旋18-甲基炔诺酮（LNG）在人工配制的模拟宫腔液中对铜的腐蚀影响。结果表明，介质pH对铜的腐蚀速率起关键作用，在同一pH下，加入LNG基本上不影响铜的腐蚀速率。XRD和SEM检测及Cu的腐蚀电位随时间的变化规律表明，无论加LNG与否，铜的表面上都只生成Cu2O，LNG使Cu2O对生成的量减少。As a supplemental study of levonorgestrel (LNG)-releasing copper- bearing intrauterine de-vice (CuIUD),the effects of LNG on corrosion behaviour of copper in simulated uterine fluid werestudied by polarhation resistance technique, XRD and SEM methods.The results illustrated thatpH of the nuid is still a most important factor to corrosion rate of copper, and at a constant pH,the addition of LNG does not affect the corrosion rate of copper and does not alter the composi-tion of oxide film, but decreases the amount of Cu2O. The variation of corrosion potential of Cuwith logarithm of time has proved the observation mentioned above.
