倍数
A is n times as great(long,much,…)as B.
A is n times greater (longer, more,…)than B.
A is n times the size (length, amount,…)of B.
A的大小(长度,数量,……)是B的n倍[或A比B大(长,多,……)n-1倍].
increase to n times
increase n times/n-fold
increase by n times
increase by a factor of n
以上四式均应译为:增加到n倍(或:增加n-1倍)。
double (增加1倍),treble(增加2倍),quadruple(增加3倍)。
Eg. The efficiency of the machines has been more than trebled or quadrupled.
这些机器的效率已提高了2倍或3倍多。
