期刊論文中分析方法研究英文摘要常見錯(cuò)誤解析
|
|
容易犯的錯(cuò)誤 中文期刊一般將英文摘要附后，但國(guó)外的CA索引的一般是英文的摘要，所以英文的摘呀也很重要。 需要引起大家的注意。 1 中英文標(biāo)題不一致 2 中英文的關(guān)鍵詞不一致 3 不要將句子寫的太長(zhǎng) 4 善用倒裝句 5 注意時(shí)態(tài)一致。 一般用的過去式。 6 用好，respectiverly. 7 用意譯，不用直譯 8 中文內(nèi)容和英文內(nèi)容要一致。 三個(gè)實(shí)例 ---------- 氣相色譜- 質(zhì)譜法測(cè)定酒樣中多種有機(jī)錫化合物- (原文） 摘 要: 對(duì)白酒中的有機(jī)錫化合物運(yùn)用NaBEt4 進(jìn)行衍生, 并采用液液萃取和氣相色譜- 質(zhì)譜法( GC-MS) 對(duì)5 種衍生物進(jìn)行分析, 建立了5 種有機(jī)錫同時(shí)分析的新方法。選用選擇離子掃描模式進(jìn)行定性和定量分析, 實(shí)驗(yàn)對(duì)影響反應(yīng)的重要參數(shù)進(jìn)行了優(yōu)化。在優(yōu)化條件下, 5 種有機(jī)錫化合物在0. 01~ 4. 0 ug mL- 1 的線性范圍內(nèi)得獲得了較好的線性, 檢測(cè)限, 相關(guān)系數(shù)為0. 992 3~ 0. 999 9, 檢測(cè)限為0. 4~ 5. 0 ug mL- 1 。在0. 05、0 . 50 和4. 0 ug mL- 1 3 個(gè)添加水平獲得了較好的回收率, 其相對(duì)標(biāo)準(zhǔn)偏差低于13. 4% 。該方法簡(jiǎn)便、快速、容易操作, 初步運(yùn)用于檢測(cè)酒樣中的有機(jī)錫化合物, 取得較滿意的結(jié)果。 關(guān)鍵詞: 有機(jī)錫; 衍生化; 液液萃取; 氣相色譜- 質(zhì)譜法; 酒樣 氣相色譜- 質(zhì)譜法測(cè)定酒樣中多種有機(jī)錫化合物 修改： Determination of variety of organotin compounds in food by gas chromatography-mass spectrometry （variety 改成 various ； 把food改成 或spirits, liquor 英文標(biāo)題和中文不一致。 中文是酒樣，英文是食品。 原文：Abstract: The or gano tins in spirit w er e derivat ized w ith NaBEt 4 and five derivativ es w ere ex t racted by liquid-liquid ex t ract ion technique and analyzed by g as chromato graphy-mass spect romet ric ( GC-MS) analy sis.A new metho d to simultaneously study the five derivat iv es w as proposed.
