[求助]
緊急求助:關(guān)于腐蝕的一篇論文,我沒(méi)看懂審稿人想要問(wèn)什么問(wèn)題
|
|
雖然是和論文有關(guān)的,但請(qǐng)版主高抬貴手,因?yàn)槲蚁朐趯I(yè)論壇里獲得更專業(yè)的解決。多謝! 文章要大修,但審稿人提的幾個(gè)修改意見(jiàn)我硬是沒(méi)看懂他要問(wèn)什么? 問(wèn)題:Page 5, line 4. You must include the pH solution at all temperatures in order to obtain a better analysis of the corrosion results.在這部分我的原文是: Generally, with the increasing of temperature the solubility of H2S and/or CO2 in the water decreases. So there are comparatively more H2S and CO2 dissolved in the solution at 90°C, which results in the pH at 90°C is lower than that at other temperatures and the dissolution of anodic ** steel is accelerated。(試驗(yàn)條件一共90°C、110°C、130°C、150°C四個(gè)溫度點(diǎn)。我的意思是溫度越高,溶入水的H2S and/or CO2 就越少,PH值就越高。所以在四個(gè)溫度中,90°C溫度最低,PH值就最小,因此能加速**鋼的腐蝕。) 他想讓我干什么? |

You can analyze the corrosion process of steel in H2S/CO2 solution with some literature reports. What influences the corrosion process of steel in H2S/CO2 solution? temperature, pH, solubility of H2S/CO2, film on steel and so on. You will get some reports/publication about the influence of pH, influence of temperature on the solubility of H2S/CO2, then explain a possible conclusion from literature report for your defense. Professor Srdjan Nesic at Ohio university (the Institute for Corrosion and Multiphase Technology) is No #1 in corrosion of oil and gas industry , they also use lots of GAMRY instruments for their researches there. http://www.corrosioncenter.ohiou.edu/projects/ you can find more reports from their publications in order to explain your results. |

1.“氣體溶解度隨溫度升高而降低”只是一般情況下(比如,常溫、常壓,氣體和溶液不會(huì)發(fā)生反應(yīng))。但是你的實(shí)驗(yàn)是在“高壓反應(yīng)釜”中進(jìn)行,這個(gè)時(shí)候的溶解度就未必遵循這個(gè)規(guī)律(H2S和CO2是否會(huì)和溶液中某些物質(zhì)反應(yīng)?)。另外,溶解度大,PH在這種情況下也未必就小。因?yàn)镻H是溶液中的H+濃度,而H+是氣體和水反應(yīng)生成的酸電離的結(jié)果。在你實(shí)驗(yàn)的情況下,(不知道是否高溫),電離系數(shù)是否受到影響?所以,審稿人是有理由懷疑你憑“常理”推斷出的結(jié)論的。 2.SCE的建議好!如果實(shí)在無(wú)法測(cè)試,只能引用文獻(xiàn)(即使這個(gè)文獻(xiàn)的結(jié)論有爭(zhēng)議)導(dǎo)出有利于自己的結(jié)論。 |
