各位幫忙翻譯幾句話: 1) 剛剝離出來的新鮮鐵銹呈黑色夾雜著紅色和淡綠色，在空氣中暴露后淡綠色消失. 2) 陽極區(qū)釋放的電子通過鋼筋流向陰極區(qū)，同時生成Fe2+與附近的Cl-離子結(jié)合生成易溶的中間相鐵-氯絡合物，隨后從鋼筋陽極區(qū)向混凝土孔隙遷移，分解為褐色的Fe(OH)2，并沉淀在陽極區(qū)周圍，同時放出H+和Cl-，它們又回到陽極區(qū)，使陽極區(qū)附近孔隙液局部酸化，Cl-再帶出更多的Fe2+，這樣Cl-加速鋼筋銹蝕。 |

剛剝離出來的新鮮鐵銹呈黑色夾雜著紅色和淡綠色，在空氣中暴露后淡綠色消失. Fresh rust that stripped off presents dark color mixed with red and light green, and the light green disappears once exposed in air. 2) 陽極區(qū)釋放的電子通過鋼筋流向陰極區(qū)，同時生成Fe2+與附近的Cl-離子結(jié)合生成易溶的中間相鐵-氯絡合物，隨后從鋼筋陽極區(qū)向混凝土孔隙遷移，分解為褐色的Fe(OH)2，并沉淀在陽極區(qū)周圍，同時放出H+和Cl-，它們又回到陽極區(qū)，使陽極區(qū)附近孔隙液局部酸化，Cl-再帶出更多的Fe2+，這樣Cl-加速鋼筋銹蝕。Electrons released from the positive column flow to the negative column through the steel bar, and Fe2+ created in positive column and the Cl- nearby combine together which produces diffluent Iron chlorine complex in intermediate phase. Then the complex drifts toward the holes of the concrete from the positive column in the steel bar, and it decomposes to Fe(OH)2 in brown, which is separated around the positive column and releases H+ and Cl+ at the same time. After then, the H+ and Cl- come back and Local acidification occurs around the pore fluid, which attribute to the increase of the Fe2+ brought by Cl-. Thus Cl- accelerate the corrosion of the steel bar. |

1) The color of fresh rust just stripped off is black mingled with red and light green which would fade away after exposed to air. 2) Anode region discharge electrons which flow through steel bar into cathod space, and produce Fe2+ simultaneously. Fe2+ then combine with nearby Cl- ion, forming intermediate phase ferrum-cholorine complex. After that, the complex migrate from steel bar anode region to the void space in concrete where it decompose into brown Fe(OH)2 which precipitate around the anode region. The H+ and Cl- ions released by aforementioned process then must come back into the anode region, acidizing the aqueous solution in the void space near anode region. The Cl- ion then would bring out more Fe2+ ion over and over again in this way, that would accelerate the corrosion process of the reinforcing steel bar. |
