受腐蚀

The mechanical expanded joint method is usually used in rehabilitating furnace pipe and big pipe board of waste heat boiler.

废热锅炉是合成氨装置的重要设备之一，其炉管与大管板焊缝受高温高压及介质腐蚀，运行一年后会产生裂纹，影响装置的正常运行。

They are also well-suited for applications experiencing vibration, mechanical stress and strong erosive forces.

还非常适合在受振动、机械应力和强烈腐蚀的环境中应用。

The interference corrosion of external steel structures located next to cathodically protected systems was evaluated based on electric field theory of stable currents.

摘要采用稳流电场理论，根据阴极保护体系周围电场分布、受电干扰构件位置和构件表面电化学行为等参数计算阴极保护系统对外部金属构件的电干扰腐蚀。

The corrosivity of soil is strongly influenced by the degree of aeration.

土壤的腐蚀很大程度上受通风度的影响。

MERO 102 粘度较高，能在金属表面形成保护油层，有效的保护金属不受外界的腐蚀，适用于黑色金属的长期封存。

By image-wise etching away one of the layers in the areas not covered by a resist and finally entirely removing the protective resist, a planographic printing plate of high quality for long run planographic printing in prepared.

通过图像，明智的腐蚀掉一个在不受抵制，最终完全取消保护性抵抗，长期运行在准备平版印刷的高质量平版印刷板所涉领域层。

The results show that one type of soft slurry occurs on the surface of mortar prism due to addition of limestone filler and a mass of thaumasite and gypsum forms in the slurry.

结果表明：掺石灰石粉使水泥砂浆受侵蚀后表面呈软泥状，主要腐蚀产物为硅灰石膏和石膏，表现为典型的TSA破坏特征，其强度损失率大于纯水泥砂浆。

Wood ash is one example. But chemical mordants such as alum are popular today. Alum is sold in many stores.

木灰就是个例子，但是化学上的腐蚀液，如现在受欢迎的矾，明矾在很多商店有售。

By the mechanics analysis of pumping rod, the calculation model of the mechanics analysis of pumping rod and neutrality point of oil tube have been established. The function of pumping rod bend space length and account method have been derived and analysis example have been completed. The simulation of wellbore trajectory and the deformation curve of sucker rod and oil tube is also given.

论文对机械磨损和腐蚀对偏磨的影响进行了分析，通过对抽油杆和油管的力学分析，建立了下冲程抽油杆、管柱下部受力分析与中性点计算模型；给出了抽油杆变形的影响因素，建立了油井井身轨迹、抽油杆和油管在油井中的变形曲线模拟软件。

Habitat loss takes several form-:S: outright loss of areas used by wild species; degradation, for example, from vegetation removal and erosion, which deprive native species of food, shelter, and breeding areas; and fragmentation, when native species are squeezed onto small patches of undisturbed land surrounded by areas cleared for agriculture and other purposes.

栖地的消失有几种型式：如，野生物种栖地的澈底消失；植被移除或腐蚀导致土质恶化，影响原生物种的食物、栖地、养育地；或因为农业或其他用地的使用，使原生物种被迫迁移至未受干扰但被其他用途所围绕的小块土地时，其活动区域遭到分割。下一个： hail。。。是什麼意思啊？
