倍數翻譯的陷阱很多，而且每個陷阱都是綿里藏針，針針見血，見血封喉！要想在倍數翻譯上不出錯，除了基本的語法過關外，還要仔細檢查，認真思考，一點點小小的差異都有可能造成誤譯、錯譯。所以，讓我們一起認真學習鉆研數字翻譯、倍數翻譯的方法，攻克重重堡壘，到達勝利彼岸！

1.A是B的N倍大/長……(或者A比B大/長……N-1倍)

一般有以下兩種英語表達方法;

(1) A is N times as large/long (形容詞/副詞原形) as B.

Eg: Asia is four times as large as Europe.

(2) A is N times larger/longer（形容詞/副詞比較級）than B.

Eg: Asia is four times larger than Europe.

(3) A is N times the size/length (形容詞/副詞的名詞形式) of B.

Eg: Asia is four times the size of Europe.

以上三句例句的中文翻譯均為：亞洲是歐洲的四倍大，或者亞洲比歐洲大三倍。

2. by 和to

(1) 動詞+ by + 倍數/百分數/數詞

Eg: The production of grain has been increased by four times this year.

今年糧食產量增加了四倍。

(2) 動詞+ to + 數詞

Eg: Last year profits rose to $201 million.

去年利潤增長到2億零100萬美元。

3. by a factor of

詞組by a factor of 在《朗文雙解》中的解釋為"if something increases or decreases by a factor of N, it increases or decreases by N times."以N倍的系數增加或減少。這個解釋表達不是很明確，現在把它分成以下兩種情況來分析：

(1)表示增加含義時

Increase/grow...by a factor of N times 增加到N倍，或者增加了N-1倍

Eg: The output of diesel oil for farm use has been increased by a factor of five times these years.

這些年來，用于農業生產的柴油產量增加了四倍。

(2)表示減少含義時

Decrease/fall...by a factor of N times 減少到1/N，或者減少了(N-1)/N。

Eg: The production has decreased by a factor of three times as against 1977.

總產量減少到1977年的三分之一。
