以下是來(lái)自O(shè)cak Y, Sofuoglu A, Tihminlioglu F, et al. Protection of marble surfaces by using biodegradable polymers as coating agent[J]. Progress in Organic Coatings, 2009,66(3):213-220.文獻(xiàn)的一段,求幫幫翻譯一下。 The water vapor permeability of uncoated and coated marble experiments were conducted by using a circularly cut (average diameter: 38.5; average thickness: 1.5mm) prepared marble. Each of the marble plates replaced in the partially water filled (1/2) cylindrical PVC containers. The plates were fixed in these containers in triplicates. Then, their lids were closed and put in the oven at a temperature of 40 ◦C, and relative humidity around 50%. The conainers were weighed every 24 h. When the vapor flow through the samples was less than 5%, the experiments were conducted for 5 more days. During this time, the measurements were repeated and recorded every 24 h. The differences were used to calculate the water vapor fluxes for uncoated and coated plates. Channel flow cell studies on the evaluation of surface pretreatments using phosphoric acid or polymaleic acid for calcite stone protection.The channel flow cell (CFC) method has been applied to determine the mechanism of calcite dissolution in acid solution . 求幫忙翻譯,CFC到底指的是什么方法。謝謝! |

有涂層和無(wú)涂層大理石的水蒸氣通透性實(shí)驗(yàn)是用已備好的削成圓形的大理石板(平均直徑38.5,厚度1.5毫米)來(lái)做的。每塊石板放在裝有一半水的聚氯乙烯材質(zhì)的圓柱形容器中。這些石板被固定在這些容器中(一式三份)。然后蓋上蓋子并置于40度,相對(duì)濕度約為50%的烘箱中。這些容器每24小時(shí)稱量一次,當(dāng)流過(guò)樣品的蒸汽少于百分之五時(shí),再繼續(xù)實(shí)驗(yàn)5天,在這段時(shí)間里每隔24小時(shí)重復(fù)并記錄所有操作。這些差值用來(lái)分別計(jì)算有涂層和無(wú)涂層的石板的水蒸氣流量。 通道流動(dòng)池 研究用磷酸或者聚馬來(lái)酸表面預(yù)處理來(lái)保護(hù)方解石的評(píng)估。通道流動(dòng)池方法(CFC)已經(jīng)被用來(lái)確定酸性溶液中方解石的溶解機(jī)理。 這前后兩段前后脫節(jié),前面是大理石,后面是方解石,至于CFC可能是作者引用了參考文獻(xiàn),或者前后文有介紹,僅憑這點(diǎn)內(nèi)容我也判斷不了。 |
