| 中文摘要: |
| 对输配水镀锌钢管内壁腐蚀瘤的形态结构特征及化学成分进行研究．研宄发现腐蚀瘤通常具有相似的内部形态结构，由腐蚀瘤表面向内基本分为3层：表面层、硬壳层和疏松多孔内核层．腐蚀瘤的主要构成物质为铁腐蚀产物，Fe3O4、FeO（OH）是其主要化学成分． |
| 英文摘要: |
| Structrues and composition of tubercles formed in galvanized pipes in water distribution system were characterized.It was found that the tubercles had similar morphological structure,almost had 3 layers: the outer layer,the "shell-like" layer and the porous interior.The main chemical composition of the tubercles were iron corrosion byproducts,such as Fe_3O_4,FeO(OH). |
