“estimate” 可以作为动词,也可以作为名词。“estimation” 只能作为名词,当二者为名词时,都有 “估计” 的意思。如何区别呢?
比如经常说的 “x” 的估计值 “the estimate of x”,那什么时候用 “estimate” 的名词,什么时候用 “estimation” 呢?

The word “estimate” can be used both as a noun and a verb. For example, as a noun, “I will give you an estimate on the amount of time it will take to complete this job”. As a verb, “I will estimate the time it will take to complete this job”.
“Estimation” is usually used only as a noun. It is the act or process of estimating. For example, “The amount of time it will take to complete this job is approximately 4 hours”. “This is only an estimation of the time. The job could take longer.” or, “This is only an estimate of the amount of time”.
综上所述,当都作为名词的时候,estimate专指结果,而estimation指过程 (process of estimating)。
ex:
estimate of x
x的估计值
estimation of x
估计x(的过程)
