Bonded darkest part order continuation corrosion, and then a second level of corrosion, gloomy and dark hiberarchy, do more corrosion, and the second time after the conclusion of the second Tati, bonded dusking hiberarchy dusking hiberarchy and time.

涂盖最阴暗部层次不让继续腐蚀，接着进行第二次腐蚀，使阴暗层次与次阴暗层次拉开，腐蚀时间不要多，第二次腐蚀完毕后，进行第二次修涂，涂盖阴暗层次及次阴暗层次。

Medium added inhibitor, could slow down the corrosion of equipment and valves, such as chrome-nickel stainless steel in sulfuric acid containing no oxygen, the great state of cremation within the range of solubility, corrosion more serious, but a small amount of copper sulfate or nitric acid and other oxidants, can change the passive stainless steel surface generates a layer of protective film to prevent the medium of etching, in hydrochloric acid, if a small amount of oxidant, which reduces the corrosion of titanium.

介质中添加缓蚀剂，可使设备和阀门的腐蚀减缓，如铬镍不锈钢在不含氧的硫酸中，很大的溶度范围内成火化态，腐蚀较严重，但加入少量硫酸铜或硝酸等氧化剂，可使不锈钢转变钝态，表面生成一层保护膜，阻止介质的的浸蚀，在盐酸中，如果加入少量氧化剂，可降低对钛的腐蚀。

Tonglu: composite or pure copper radiator heating system in the use of one-pipe is dangerous, because one-pipe system, high-speed hot water would have a copper corrosion, should carefully chosen.

然而由于钢制散热器怕水中的氧气，它对供热系统要求很严格，在不安全的系统中会出现腐蚀（腐蚀点大部分在管壁上，而不在焊接部位）；而另外一个事实是，目前我们国内的许多采暖系统还不是很完善，虽然国家对采暖水质早有规定，但仍有许多物业不能按标准执行。

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。

The results of electrochemical measurements indicated that in the presence of indomethacin powder it slightly increased the corrosion rate of copper if pH of the fluid was not under control and it did not change the corrosion rate if the pH was daily adjusted to maintain constant roughly. The experimental results for medication by indomethacin releasing silastic were basically the same as those with powdery indomethacin.

结果表明在不调整介质pH的情况下，由于消炎痛有使介质pH降低的作用，因此使铜的腐蚀速度略有上升；在调整模拟宫腔液的pH保持恒定的情况下，消炎痛几乎不影响铜的腐蚀速度；通过消炎痛缓释硅橡胶加药的实验结果与直接加药基本相同；在模拟宫腔液中，添加消炎痛具有促使铜的腐蚀产物中不溶性产物Cu〓O膜生成的作用，消炎痛使Cu〓O生成的量增加且致密。
