| 中文摘要: |
| 以海洋环境中一个非常重要的局部腐蚀形式——低水位加速腐蚀（ALWC）为对象，自其检测、发生原因、防护三个方面就国内外的文献报告进行综述分析。在检测方面，首先介绍了常用的宏观观察这一被动形式，并突出其特征，然后介绍了利用海水中可溶性无机氮含量作为ALWC发生概率预测这一主动形式，分析其优势与不足。在发生原因方面，在对将ALWC认定为一种典型的微生物腐蚀（MIC）形式的认知过程进行介绍之后，重点分析了微生物对ALWC作用机制不清晰的原因，并建议在后续研究中突出动态演变过程，结合高通量测序等分子生物学技术，确定在不同的阶段影响ALWC的关键微生物，且进一步在大气-海水体系下研究典型菌株及其协同作用的影响，提出微生物对ALWC的作用机制。在防护方面，根据新建和已建钢结构设施分别对传统和针对ALWC所具有的MIC与局部腐蚀特性的新型高效防护方法进行了介绍，并分析了防护方法的优缺点。 |

| This article takes accelerated low water corrosion (ALWC) as the object, which is a significant local corrosion pattern in marine environments, to review and analyze the related literature and reports in three aspects: detection, cause, and protection. For the detection, macroscopic observation as a passive method was introduced firstly, and the characteristics were emphasized; and then the advantages and defects of an active approach were analyzed, in which ALWC prediction was achieved by the positive linear correlation between the content of dissolved inorganic nitrogen in seawater and ALWC occurrence probability. For the cause, it was focused on factors leading to the indeterminacy in the action mechanisms of microorganisms towards ALWC, after the description of the cognitive process on the view that ALWC was a typical form of microbially influenced corrosion (MIC). It was suggested to highlight the dynamic development process in the future studies, and ascertain key microorganisms for ALWC at different stages with the aid of molecular biological techniques like high-throughput sequencing. Also the impact of typical strains and their synergy was investigated in the atmosphere-seawater systems, and the function mechanism of microorganisms towards ALWC was proposed. For protection, traditional and novel efficient protection methods designed for ALWC with the unique MIC and local corrosion features were described on the basis of new and former steel structures, and the merits and disadvantages of these approaches were analyzed. |
