ballpark figure

大概的數(shù)字

An acceptable and reasonable estimate. (NOTE: a “ballpark” is an enclosed field or stadium for playing the American game of baseball)

EXAMPLE: At this early stage of planning, I don't need the exact cost of the new project, but just a ballpark figure will be quite helpful.

在規(guī)劃的早期,，我不必知道新項目的精確成本,，有一個大概的數(shù)字就會很有幫助。
