C. E.). The anodie dissolution process has been investigated in terms of potential-sweep and potential-step polarization techniques. For the finely dispersive phase in the alloy, a new model has been developed to describe the selective anodic dissolution process, which is eontrolled by electrochemical polarization. 收稿日期: 1987-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张建中 王景韫 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I6/568 1#12 2 #12 3 #12 4 #12 5 马翔.分析化学,1984;12(6) 496 6 傅岩松.浸蚀定量法在耐热钢相分析中的应用及其理论基础探讨,金属研究所硕士学位论文,1985 No related articles found!
