1.A是B的N倍大/长…(或者A比B大/长…N-1倍)

杭州翻译公司发现一般有以下两种英语表达方法;

(1) A is N times as large/long (形容词/副词原形) as B. Eg: Asia is four times as large as Europe. (2) A is N times larger/longer（形容词/副词比较级）than B. Eg: Asia is four times larger than Europe. (3) A is N times the size/length (形容词/副词的名词形式) of B. Eg: Asia is four times the size of Europe.以上三句例句的中文翻译均为：亚洲是欧洲的四倍大，或者亚洲比欧洲大三倍。

2. by 和to

(1) 动词+ by + 倍数/百分数/数词  杭州翻译公司举例: The production of grain has been increased by four times this year. 今年粮食产量增加了四倍。

(2) 动词+ to + 数词  杭州翻译公司举例: Last year profits rose to $201 million.去年利润增长到2亿零100万美元。

3. by a factor of

词组by a factor of 在《朗文双解》中的解释为"if something increases or decreases by a factor of N, it increases or decreases by N times."以N倍的系数增加或减少。这个解释表达不是很明确，杭州翻译公司现在把它分成以下两种情况来分析：

(1)表示增加含义时  increase/grow…by a factor of N times 增加到N倍，或者增加了N-1倍  杭州翻译公司举例: The output of diesel oil for farm use has been increased by a factor of five times these years. 这些年来，用于农业生产的柴油产量增加了四倍。

(2)表示减少含义时  Decrease/fall…by a factor of N times 减少到1/N，或者减少了(N-1)/N。 杭州翻译公司举例: The production has decreased by a factor of three times as against 1977. 总产量减少到1977年的三分之一。

要想在倍数翻译上不出错，除了基本的语法过关外，还要仔细检查，认真思考，一点点小小的差异都有可能造成误译、错译。
