容易犯的错误 中文期刊一般将英文摘要附后，但国外的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 中英文标题不一致 2 中英文的关键词不一致 3 不要将句子写的太长 4 善用倒装句 5 注意时态一致。 一般用的过去式。 6 用好，respectiverly. 7 用意译，不用直译 8 中文内容和英文内容要一致。 三个实例 ---------- 气相色谱- 质谱法测定酒样中多种有机锡化合物- (原文） 摘 要: 对白酒中的有机锡化合物运用NaBEt4 进行衍生, 并采用液液萃取和气相色谱- 质谱法( GC-MS) 对5 种衍生物进行分析, 建立了5 种有机锡同时分析的新方法。选用选择离子扫描模式进行定性和定量分析, 实验对影响反应的重要参数进行了优化。在优化条件下, 5 种有机锡化合物在0. 01~ 4. 0 ug mL- 1 的线性范围内得获得了较好的线性, 检测限, 相关系数为0. 992 3~ 0. 999 9, 检测限为0. 4~ 5. 0 ug mL- 1 。在0. 05、0 . 50 和4. 0 ug mL- 1 3 个添加水平获得了较好的回收率, 其相对标准偏差低于13. 4% 。该方法简便、快速、容易操作, 初步运用于检测酒样中的有机锡化合物, 取得较满意的结果。 关键词: 有机锡; 衍生化; 液液萃取; 气相色谱- 质谱法; 酒样 气相色谱- 质谱法测定酒样中多种有机锡化合物 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 英文标题和中文不一致。 中文是酒样，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.
