㈠ 85℃水浴加熱迴流提取2次用英語怎麼說

85 C water bath heating, refluxing and extracting for 2 times

㈡ 英語翻譯 RT..怎麼翻譯恰當,「作為萃取物等效於新鮮」么很疑惑.那個"equiv."怎麼翻譯

整句話的上下文貼上來才知道「怎麼翻譯恰當?」.你那樣翻譯不對!as 在這里不應內是作「作為……」解!容
fresh:
在這里是:「n.開始;新生;泛濫」——而你翻譯中使用的「新鮮」一詞實際上是一個形容詞;
如果「equiv.to」做「等於……」解,extract 則也應是名詞,而且應與「fresh」一樣,同為「抽象名詞」; 你翻譯成「萃取物」則屬於「具體名詞」了,在英文里當為復數形式才對.兩廂不可能「相等」;
僅從你提供的這點文本字面含義翻譯的話,也只能是:「萃取猶如新生」

㈢ 請幫忙翻譯成英文,急!!

1.5) The above analysis, welding procts processed colloidal major adverse internal rupture analysis Client proct is in the process of returning welding processing method is flawed, procts without fully warmed by the heat process, allowing a small number of procts subject to greater external vibration (or impact) PCB damage to the procts of colloid and the combination of his appearance. breakdown procts colloidal bad. 1.6) in order to prove the above analysis : reusable packaging similar to the appearance of my Liangpin reservoir simulation procts in the past when the heating temperature SMT machine so heating tests. Heating procts will be on stage heating (heating temperature of Taiwan : 255 ° C), down from about 10 seconds. Colloidal not cooling procts, or indirectly done anything in a positive light procts colloidal external impact. Observer status exterior procts again, The results showed the bottom of colloidal procts (colloidal or indirectly) with a clear separation of PCB material adverse combination Department (Fig9. Fig10 said), providing customers with samples appearance similar situation. Fig9 : bottom of colloidal materials with a clear separation Fig10 : PCB PCB build a separate aspect of colloid and (2) corrective measures to prevent Corrective Action /Prevent Action : 2.1) above analysis, I proposed the use of welding procts in a client to properly handle the security, SMT machine in the course of operations to avoid procts from larger external vibration (or impact) particularly in the finished SMT machine, the heat not yet fully colloidal suspension sclerosis (especially colloidal internal). If the procts subject to vibration (or impact) will be very easy to damage created by the combination of colloidal materials with PCB separation bad. Appearance damage; The direct cause serious internal circuits have access, resulting in unstable procts -- Open or bad. 2.2) recommended clients in completed SMT machine, all alts that were ready to lay the best use of every piece of sponge or bubble paper isolation circuit board. prevent collisions between the PCB and PCB bad vibration friction procts; Canal light possible light up avoid excessive vibration, the effects of colloid and PCB material, and his appearance or the proct unstable.

㈤ 將下面這段文字翻譯成英文

甲苯和乙醇都是有機合成中常用的原料,同時也是化工工業中用途非常廣的有機溶劑。常壓下,甲苯和乙醇會形成共沸混合物,共沸溫度為76.9℃,共沸組成中乙醇67.8wt%,常規精餾無法清晰分離。本文採用萃取精餾的方法分離甲苯-乙醇共沸物系,並使用Aspen plus模擬軟體進行工藝流程模擬與優化。
首先運用Aspen plus繪制甲苯-乙醇二元物系的氣液平衡相圖,進行初選萃取劑;採用Flash模塊繪制等相對揮發度曲線和殘余曲線,選擇合適萃取劑並判斷其可行性,正丁苯和正丙苯均能有效提高甲苯-乙醇揮發度,達到分離效果。
然後運用Aspen plus對正丁苯和正丙苯作萃取劑分別進行流程模擬,考察了原料和溶劑進料位置、迴流比、溶劑進料流率等參數對產品純度的影響規律,得到合適的操作參數。計算結果表:正丁苯作萃取劑時,萃取精餾塔塔板為20塊,萃取劑和原料進料位置分別為第8塊和第19塊,迴流比為1.1,溶劑進料流量為220kg/hr;溶劑回收塔塔板為24塊,進料位置為第8塊,迴流比為2.4,甲苯和乙醇產品的質量分數都達到了99.9%。正丙苯作萃取劑時,萃取精餾塔塔板為35塊,萃取劑和原料進料位置分別為第16塊和第32塊,迴流比為2.4,溶劑進料流量為220kg/hr;溶劑回收塔塔板為30塊,進料位置為第12塊,迴流比為4.8,甲苯和乙醇產品的質量分數都達到了99.9%。
最後對兩種萃取劑的能耗和經濟性進行對比,正丁苯作萃取劑更適合分離甲苯-乙醇共沸物系。
Toluene and ethanol are commonly used in organic synthesis of raw materials, but also the chemical instry is widely used in organic solvents. Under normal pressure, toluene and ethanol will form an azeotropic mixture, azeotropic temperature of 76.9 ℃, azeotropic composition of ethanol 67.8wt%, conventional distillation can not be clearly separated. In this paper, toluene - ethanol azeotrope was separated by extractive distillation and the process flow was simulated and optimized using Aspen plus simulation software.
Firstly, the gas - liquid equilibrium phase diagram of toluene - ethanol binary system was used to extract the initial extraction agent. The relative volatility curve and resial curve were drawn by Flash mole, and the appropriate extraction agent was selected and its feasibility was determined. Benzene and n-propylbenzene can effectively improve the toluene - ethanol volatility, to achieve separation effect.
The effects of parameters such as raw material and solvent feed position, reflux ratio and solvent feed rate on the purity of the proct were investigated by using Aspen plus for the extraction of n-butylbenzene and n-propylbenzene as extraction agents. The appropriate operating parameters The Calculated results table: n-butyl benzene as extractant, extractive distillation tower tray 20, extractant and raw material feed position were 8 and 19, the reflux ratio of 1.1, the solvent feed flow of 220kg / Hr; solvent recovery tower for the 24, the feed position for the first eight, the reflux ratio of 2.4, toluene and ethanol procts have reached 99.9% of the mass fraction. When the extraction agent is used as the extractant, the extractive distillation column is 35, the extraction agent and the raw material feed position are 16th and 32th respectively, the reflux ratio is 2.4, the solvent feed flow is 220kg / hr, the solvent Recycling tower plate for the 30, the feed position for the first 12, the reflux ratio of 4.8, toluene and ethanol procts have reached 99.9% of the mass fraction.
Finally, the energy consumption and economy of the two extractants were compared, and n-butylbenzene was more suitable for the separation of toluene-ethanol azeotrope.

㈩ 人才迴流英語怎麼說

return of talent or brain gain. eg: 台灣和印度的 人才 外流變成了 人才迴流 。 Taiwan and India, has shifted into a brain circulation. 盡管中國經濟迅速發展,同時政府積極鼓勵 人才迴流 , 但是還是有越來越多的優秀 人才 選擇留在更富裕的國家,在那裡, 他們通常能獲得更好的生活條件,事業上發展的機會更有力, 同時可以依照個人意願決定自己想養育子女的數量。 Despite the booming economy and government incentives to return, an increasing number of the country's brightest minds are relocating to wealthier nations, where they can usually benefit from higher living standards, brighter career opportunities and the freedom to have as many children as they wish.
