output

Compared meaning: the amount of something produced (noun).

比较义项：产量（n.）。

• production

  General term for the total amount a factory, industry or company makes; common in phrases like 'go into production' or 'mass production', describing goods broadly rather than a measured rate.

  泛指工厂、行业或公司生产的总量；常见于 go into production（投产）、mass production（大规模生产）等搭配，笼统描述产品产出，而非某一测量出的速率。

  The new model finally went into production last month.

  这款新车型上个月终于投产了。

• yield

  Especially used for farm produce and other natural output, and often for an amount measured against input, as in 'yield per acre'; rarely used for factory or company output.

  尤指农作物等自然产出，也常用于按投入衡量的产出，如 yield per acre（每英亩产量）；很少用来指工厂或公司的产出。

  The farm's wheat yield per acre improved with the new fertilizer.

  使用新肥料后，这家农场每英亩的小麦产量提高了。

• output 本词

  Emphasizes the measurable quantity produced by a machine, worker or system in a given period, often in technical or economic contexts such as 'output per hour'.

  强调机器、工人或系统在一段时间内产出的可测量数量，常见于技术或经济语境，如 output per hour（每小时产量）。

  The new machine doubled the factory's output per hour.

  新机器让工厂每小时的产量翻了一番。

Production, yield and output all mean an amount produced. Production is the general word for a factory's or company's total. Yield is for farm produce, measured against input. Output is a measurable amount from a machine or system. Other meanings are not compared.

这三个词在“产量”这一意义上相近，但侧重点不同：production 泛指工厂、行业或公司生产的总量，常见于 go into production（投产）、mass production（大规模生产）等搭配；yield 侧重农作物等自然产出相对于投入的产出量，如 crop yield（作物产量）；output 强调机器、工人或系统在一段时间内产出的可测量数量。这里不比较 production 的“（戏剧、电影等的）制作、演出”义，也不比较 yield 的“（投资的）收益率”义和 output 的“（计算机的）输出”义。
