| 目的 研究三亚海域不同海区环境因素和腐蚀性差异。方法 对三亚海域亚龙湾和红塘湾两海区的自然环境因素数据和海生物种类及生长速度进行比较分析， 并对钢、 不锈钢、 铝合金和铜合金等4种典型金属材料在两海区的腐蚀性能进行对比研究。结果 两海区的海水环境因素除盐度外差别不大， 随月份的变化规律一致。由于钛合金在海水中具有良好的耐蚀性， 因此选用PVC和钛合金分别代表非金属材料和金属材料研究两海区海生物附着规律， 结果发现两海区附着海生物的数量和种类差别较大， 钛合金板的海生物附着量明显多于PVC板。四种典型金属材料在红塘湾和亚龙湾相同区带条件下的腐蚀速率相差很小。结论 两海区环境因素及腐蚀性差异不大， 具有较好相关性。 |

| Objective To study differences in environment factors and corrosivity in different Sanya sea areas. Methods The natural environment factors in Hongtang Bay were compared with those in Yalong Bay. Furthermore, the species and the growth speed of marine organisms were also compared. Four kinds of typical metals and alloys, namely, steel, stainless steel, aluminum alloy and copper were compared for corrosivity in the two sea areas. Results It showed that sea water environment factors except salinity in the two sea areas were in good coincidence as well as their variations within months. Ti and PVC were chosen as the representatives of metal and nonmetal materials respectively to study the laws of biofouling, considering the excellent corrosion resistance of Ti in seawater. It showed that the species and amount of marine organisms adhered were quite different in the two sea areas, and the adhesion amount of marine organisms on the Ti plate was larger than that on the PVC plate. Corrosion rates of the four kinds of typical metals and alloys differed very little in the same zone conditions in the two areas. Conclusion Environment factors and corrosivity in the two sea areas have little differences and there is good relativity between environment factors and corrosivity. |
