您好,
倍数小一点的时候有专有名词或者形容词。如2倍 Double﹐3倍Triple﹐4倍Quadruple.....倍数大的会用times。如20倍 = 20 times﹐30倍 = 30 times。
A multiple of 20 是指20的倍数﹐并不是20倍。数学上用得比较多。例如 Write down all multiples of 3 greater than 10 but smaller than 20。
至於一到十的倍数可以参考以下的常见词:
郭嘎嘎2222
quadruple：（使）变为四倍；由四部分（或人、群体）构成的；四方面的；四倍的。
1、读音
英 ［kwɒ＇druːpl］；美 ［kwɑː＇druːpl］
2、用法
用作名词 （n．）
For example， a farm built on cheap oil suffers when crude prices quadruple．
例如，一个在原有便宜时建起来的农场，会在原油价格变成四倍时遭受损失。

英语中，倍数的表达有许多细微的区别
1、表示“几倍大小（长短；数量）”，由“倍数＋ the size（length，amount……）”结构组成。
例如：The earth is forth－nine times the size of the moon．
地球是月亮的49倍大。
2、 表示“……比……大几倍”，由“倍数＋形容词（副词）比较级”结构组成。
例如：This box is three times bigger than that one．
这个盒子比那个盒子大三倍。
The grain output is 8 percent higher this year than that of last year．
今年比去年粮食产量增加8％。
3、 表示“……是……倍”，由“倍数＋ as ＋形容词＋ as ＋”结构组成。
例如：Our factory is twice as big as theirs．
我们的工厂是他们的三倍。
I have three times as many as you．
我有你三倍那么多。［注］ 一倍用once，两倍用 twice．
4、还可以用by＋倍数，表示增加多少倍。

一、用times 表示倍数（一般限于包括基数在内三倍或三倍以上的数。表示两倍的数，一般用twice ）。其句式有：(前三种为主) 1. “… times ＋形容词/ 副词的比较级＋than …”例如：Line AB is three times longer than line CD. 线段AB 是（线段）CD 的三倍长。 This hall is five times bigger than our classroom. 这个大厅比我们的教室大5 倍。 This rope is twice longer than that one． This hall is five times bigger than our classroom． The car runs twice faster than that truck． 2. “… times +as + 形容词/ 副词的原级＋as …”例如： This table is three times as long as that one. 这张桌子是那张桌子的三倍长。 This dictionary is five times as thick as the one you borrowed from the library. 这本词典的厚度是你从图书馆借的那本（厚度）的5 倍。 Asia is four times as large as Europe 亚洲的面积是欧洲的四倍。 This big stone is three times as heavy as that one． 这块大石头的重量是那一块的三倍。（这块石头比那块重二倍） The plane flew ten times as high as the kite． 那架飞机飞行高度是那个风筝的十倍。（高出九倍） 3. “… times + the + 名词（如：size，height，weight，length， width, age等）＋of …”例如： The earth is 49 times the size of the moon. 地球的体积是月球的49 倍。 This river is three times the depth of that one. 这条河是那条河的三倍深。 This street is four times the length of that street. 这条街是那条街的四倍长。 This hill is four times the height of that small one．这座山的高度是那座小山的四倍。（比那座小山高三倍） 4. “… times + more ＋名词＋than …”例如： He earns five times more money than he did ten years ago. 他现在挣的钱比十年前挣的多5 倍。 There are twice more students in our class than in theirs. 我们班的学生人数比他们班多两倍。 5. “… times +as many （或much ）＋名词＋as …”例如： We've produced twice as much cotton this year as （we did ）ten years ago. 今年我们生产的棉花比十年前多了一倍。（汉语中的多一倍实际上也指两倍一样多。） He has got three times as many books as his sister. 他拥有的书的数量是他妹妹的3 倍。 6. “…times + what 从句”例如： The length of the road is four times what it was three years ago. 这条路的长度是三年前的4 倍。 The price of the meat is twice what it was last year. 肉价是去年的两倍。 7. “…times + up on （或over ）…”例如： The size of the sun is a million times over that of the earth. 太阳的体积比地球的体积大一百万倍。 He is three times up on your age. 他的年龄是你的4 倍（或：比你的年龄大3 倍）。 8. “…+by + …times ”例如： Compared with last year，our coal output has increased by three times. 与去年相比，我们的煤产量增长了3 倍。 His speed is faster than mine by four times. 他的速度比我的快4 倍。 9. “… times + compared with ＋被比较对象”例如： The number of the students in our school has increased four times compared with 1980. 我们学校的学生人数比1980 年增加了4倍。 10. “… times + that of + 被比较对象”例如： In this workshop the output of July was three times that of January. 这个车间七月份的产量是元月份的3 倍。 二、用分数、百分数表示倍数。例如： The box is one-third bigger than that one. 这个盒子比那个盒子大三分之一。 Last year the output value of industry was 59 percent higher than that of 1976. 去年工业产值比1976 年增长了59 ％。 My command of English is not half so good as yours. 我英语掌握得还不及你的一半儿好。 三、用again （一倍），double （两倍），triple （三倍），fourfold （四倍）等词表示倍数。 例如：My Aunt is as old again as I am. 我姑姑的年龄比我大一倍。 The top-brand clothes are often sold as double the normal price here. 这里名牌衣服的售价经常比正常的售价高一倍。 The new work procedure tripled the output. 新工艺使产量增加两倍。 The output of grain increased fourfold. 粮食产量增加了三倍。
