腐蚀的

The pure screw dislocation is easily etched along the steps that the dislocation terminates. Consequently a small Ga-polar plane is formed to prevent further vertical etching,resulting in an etch pit shaped like an inverted truncated hexagonal pyramid at the terminal chiasma of two surface steps.

纯螺位错易于沿着由它结束的表面阶梯被腐蚀，形成一个小的Ga极性面以阻止进一步的纵向腐蚀，因而其腐蚀坑是位于两个表面阶梯交结处的截底倒六棱椎。

The results showed that soil corrosion of mild steel was not only influenced by surrounding media but also controlled by the amout, structure and efflorescence extent of corrosion products at different stages.

本工作以埋在苏打盐土中的A3钢为例，用实验论证低碳钢的腐蚀速度与腐蚀发生与发展的不同时期密切相关，为认识土壤中钢铁的自然腐蚀规律及其机理提供依据。2实验方法2。

According to corrosion damage distribution law, cumulative distribution law of corrosion damage is conducted by four membership functions of fuzzy equivalent corrosion damage.

结合腐蚀损伤的分布规律，选用了4种形式的模糊等效腐蚀损伤的隶属函数来表示腐蚀损伤的累积分布规律。

This could be attributed to the following reasons: fined grain is benefit for the improvement of corrosion property, in which the homogeneous distribution of Al element was also good to improve corrosion performance.

此外，稀土改善耐腐蚀性能的原因可能是减少了有效阴极相Mg_17A1_12的数量和新相具有耐蚀性以及提高了合金的腐蚀电位，而碱土元素则降低了合金的腐蚀电位。

Among them Al_(11)La_3 photograph is accumulated as a result of lesser cathode face, to quickening its all round of magnesian matrix corrode do not remove apparent effect; and area of cathode of lumpish Al_8LaMn_4 photograph is larger, form small couple to corrode with matrix, quickened matrix corrode.

其中Al_(11)La_3相由于较小的阴极面积，对加速其四周镁基体的腐蚀不起明显功能；而块状的Al_8LaMn_4相阴极面积较大，和基体构成微电偶腐蚀，加速了基体的腐蚀。

The X-ray diffraction results of corrosion products and scanning electron microscopy analysis of corrosion surface were used to comparatively investigate the corrosion properties of Zn/Al coatings, and to study the self-sealing mechanism.

研究表明，与纯锌、纯铝涂层相比，对于钢基体，锌铝复合涂层具有更加合适的阴极保护电位，可以大大提高防护寿命；海水环境中涂层表面会形成一层致密稳定的腐蚀产物膜，能有效阻止腐蚀介质向涂层内部的渗透，涂层会保持在一个较低的腐蚀速度。

Of key interest was the trends of corrosion potential on initial period. Corrosion potential–time measurements were undertaken after the samples exposed to the air for 24 h were polarized anodically and cathodically in acetic acid solution. With analyzing of the curves of electrochemical polarization and SEM and EDS data of the samples ,corrosion and electrochemical behavior and mechanism of localized corrosion of 316L stainless steel in acetic acid solution with Cl- were discussed.

测试了空气中钝化24小时后、阴极极化后和阳极极化后，试样在醋酸溶液中自腐蚀电位随时间变化的曲线，结合阴极极化曲线、阳极极化曲线、试样的SEM微观观察和EDS成分分析，初步探讨了316L不锈钢在含Cl-醋酸溶液中的腐蚀电化学行为和点腐蚀发生的机理。

The corrosion of concentrated sulfuric acid is related to the temperature and the impurity content. The corrosion rate is raised up when the temperature is higher. If the sulfuric acid has some ion nitrated , the pipe corrosion will raise up, too. The product's color is unusual.

浓硫酸管线的腐蚀还与温度及其杂质含量有关，温度的升高，腐蚀速率明显上升；而产品硫酸中含有的硝酸根离子则加剧了硫酸管线的腐蚀，且导致产品硫酸颜色异常。

A three layers BP neural network model for the corrosion weight-loss of the gas turbine wheel part in heavy oil impurity environments was set up by using Nimonic 80A corrosion weight-loss data in the different heavy oil impurity environments, and the influence law of the gas turbine wheel part corrosion weight-loss was predicted.

利用三层BP神经网络，根据已有的镍基合金（Nimonic 80A合金镍基沉淀硬化）在不同重油杂质环境参数下的腐蚀速度数据，建立了燃气轮机的涡轮部件在重油杂质环境中腐蚀失重的人工神经网络模型，并进一步预测了腐蚀失重。

Experimental results show that cycle loading accelerated the corrosion of steel bar.

结果表明，循环荷载作用对构件钢筋的腐蚀有明显的促进作用，证实了腐蚀疲劳是腐蚀环境和循环荷载耦合作用的结果。

What would he tell Judith and the children?

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
