In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。

本文从锅炉发生低温腐蚀的机理入手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；笔者专门从事真空相变锅炉的设计研究已十多年，根据上述观点设计的数百台产品已经过多年实际运行，未发现明显低温腐蚀。

Through studying mechanism of drilling string failure in the action of interaction of cyclicstresses and corrosion, we find fracture source is accord with pitting corrosion inside surface ofdrilling string, crack from pitting corrosion lead to drilling string failure, the process of drillingstring failure is new drilling string → corrosion pit forming and crack initiation → corrosionfatigue crack propagation→piercement or fracture.

通过研究在钻柱交变应力和腐蚀的交互作用下的机理发现，腐蚀疲劳裂纹源与钻杆内壁蚀坑对应，蚀坑萌生裂纹造成钻柱失效，钻柱腐蚀疲劳破坏过程归结为：新钻杆—蚀坑形成及裂纹萌生—裂纹扩展—刺穿和断裂。

The result of study showed:1 The effect of some inorganic urea inhibitor enzyme indicated boracic acid inhibits the activeness of urea enzyme in soil well, delayed the speed of urea hydrolysis in the soil and decreased the volatilization of ammonia , boracic acid,can be chosen as a inorganic urea enzyme inhibitor.2 The effect of some organic urea inhibitor enzyme showed that the dissociative Humic Acids of turfy soil and weathered coal inhibit the activeness of urea enzyme in soil well.
