Due to slope cable bears barely alternative load longtime in nature environment, it is easy to corrosion and wreck. Seriously, the bridge is possibility to collapse in strictness air empoison, water pollution, seashore and ocean surroundings. Therefore, to study cable's corrosion widely and to inhibit corrosion process are very important for increase endurance and safety of bridge construction.

由于斜拉索长期承受交变载荷并暴露于自然环境中，特别是大气污染严重地区、水污染严重地区、海滨及海洋环境，极易发生腐蚀破坏，严重者还会因坍塌而造成生命及财产的巨大损失，因此，全面研究桥梁拉索的腐蚀，阻断腐蚀的成因，对提高桥梁结构的耐久性与安全性具有重要意义。

Hot corrosion behavior of Na2SO_4 coated B-1900 alloy was studied in air at 827 and 750℃.Corrosion kinetics of the coated alloy was gravimetrically measured,and contents of water soluble ions in the reaction products were chemically analyzed.X-ray diffraction and EMP techniques were employed to determine the components and morphology of the corrosion product scale.

用涂 Na_2SO_4盐膜法研究高温合金 B-1900在827℃和750℃于空气中的热腐蚀行为，测定其腐蚀动力学曲线，用 X -射线衍射和电子探针元素面扫描方法分析腐蚀产物的相组成和成份，还对其中的水溶性离子进行化学定量分析。

Therefore, the stone consist of idiomorphism and half idiomorphism mineral, the erode speed is slower.

因此，由自形、半自形的矿物组成的石材，腐蚀速度一般较慢；他形成矿物组成的石材，腐蚀速度较快；颗粒的大小对于腐蚀速度的影响主要表现为粒度越粗，颗粒的总表面积越小。

Sulfate-Reducing Bacteria was the most important bacteria in microbiologically influenced corrosion,the corrosion cause by SRB was about 10 percent of total corrosion.

硫酸盐还原菌是微生物腐蚀中最为重要的菌种，其引起的腐蚀约占所有腐蚀总量的10%。

The excessive naphthenic acid corrosion of the vacuum distillation tower was introduced.

介绍了减压塔受环烷酸腐蚀的严重程度，探讨了腐蚀机理和应用 316L不锈钢抗腐蚀的效果。

Firstly, achieving a new low and high cycle noninterfering loading, the high frequency induction local heating, the control of high cycle vibration frequency and amplitude, and the crack propagation real-time detection, an experimental system of L-HCCF at elevated temperature is established. Secondly, under two vibration frequency (50Hz and 100Hz), the contrast experiment of light and serious corrosion disc slots is done. It is found that the experimental L-HCCF life of serious corrosion disc is less than that of light's, but its dispersion is larger, and the experimental failure is identical with the service's.

首先，进行大量试验工作，提出了高低周疲劳载荷的新型加载方案，并解决了高频感应局部加温、振动调频及裂纹实时监测等多个技术难点，建立了涡轮盘全尺寸高温复合疲劳试验系统；验证试验做到了故障再现；接着进行了两种频比（振频50HZ与100HZ）的轻、重腐蚀盘的对比试验；由对榫槽第一齿进行裂纹实时跟踪，得出了枞树型榫槽的复合疲劳裂纹扩展特点规律；对榫齿断口进行的金相分析表明：裂纹首先由第一齿开始，断口系复合疲劳；试验结果显示：重腐蚀盘试验寿命较轻腐蚀盘有显著的下降，而且分散性较大。
