腐蚀状态

From the angle of engineering application, this article analysed the corrosion characteristics and damage causes of the current structural used concrete in the region of Hangzhou gulf, on the basis of on-site survey of all the Marine concrete projects in that area. Taking HPC used in Marine as research objective, this article put great emphasis on the influence of the composition cementing material system to concrete performance, and make a preliminary probe into the action mechanism of the composite effects of various mineral materials in improving the performance of concrete by laser measuring size machine and EMPA. Through experiments, the article discussed how chloride ingression in concrete will be effected by such factors as exposure time, chloride binding, environment temperature, stress and cracks conditions; and also analysed the symptoms of these factors in the model of concrete service life prediction by conference to all related research reports both home and aboard. On the foundation of abovementioned research, this paper brought up an engineering model of service life prediction of marine concrete, which is based on chloride-induced corrosion.

I was also serenaded by a hooting owl. Near at hand you could fancy it the most melancholy sound in Nature, as if she meant by this to stereotype and make permanent in her choir the dying moans of a human being —— some poor weak relic of mortality who has left hope behind, and howls like an animal, yet with human sobs, on entering the dark valley, made more awful by a certain gurgling melodiousness —— I find myself beginning with the letters gl when I try to imitate it —— expressive of a mind which has reached the gelatinous, mildewy stage in the mortification of all healthy and courageous thought.

还有一只叫个不停的猫头鹰也向我唱起小夜曲来，在近处听，你可能觉得，这是大自然中最最悲惨的声音，好像它要用这种声音来凝聚人类临终的呻吟，永远将它保留在它的歌曲之中一样，——那呻吟是人类的可怜的脆弱的残息，他把希望留在后面，在进入冥府的人口处时，像动物一样嗥叫，却还含着人的啜泣声，由于某种很美的"格尔格尔"的声音，它听来尤其可怕——我发现我要模拟那声音时，我自己已经开始念出"格尔"这两个字了，——它充分表现出一个冷凝中的腐蚀的心灵状态，一切健康和勇敢的思想全都给破坏了。

Working conditions of drilling string is complex underground, various factors ofteninteract, in the process of drilling, drilling string acts complex movement in drill fluid, drillfluid unavoidable corrupt drilling string because such as oxygen, hydrogen sulfide and manysalts are dissolved in it. At the same time, many cyclic stresses act on drilling pipe, such asflexural cyclic stress, torsional cyclic stress.

钻柱在井下的工作状态是复杂的，常常是多种因素交织在一起的，在钻井过程中，钻柱在溶解了氧、硫化氢及各种盐类的钻井液中作复杂运动，不可避免的受到它们的腐蚀作用，同时还要受到弯曲、扭转等交变应力作用。

Remaining in a pure state uncorrupted by civilization .
