1 [C] amount or estimate that is not exactly right but nearly so 近乎准确的量或估计; 近似值:
3000 students each year would be an approximation. 每年3000名学生, 这是个大约的数字.
2 [U] process of being or getting near (in number, quality, etc) 概算; 近似法.
n [U and C]
a number, amount etc that is not exact, but is almost correct
= estimateapproximation of an approximation of the total numbera rough/crude approximation
(=one that is not very exact) Could you give us a rough approximation of the likely cost?a good/close/reasonable approximation
something that is similar to another thing, but not exactly the sameapproximation of/to It was the nearest approximation to a crisis she'd ever experienced.
1. This is a close approximation to the truth. 那很接近于事实真相。
