yield

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 本词

  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

  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。

Compared meaning: profit or benefit from investment or effort (noun).

比较义项：投资或努力带来的回报、收益（名词）。

• return

  General, common word for the profit or benefit gained from an investment or effort; often used in the phrase 'return on investment', and can mean either a lump sum or a rate.

  通用、常见的词，指从投资或努力中获得的利润或收益；常用于“return on investment（投资回报）”这一短语中，既可以指一笔总金额，也可以指一个比率。

  Real estate can offer a better return than a regular savings account.

  房地产投资往往比普通储蓄账户带来更好的回报。

• yield 本词

  More technical and formal; specifically the rate of profit or income that an investment produces, expressed as a percentage, common in finance for bonds, stocks and savings.

  更具技术性、更正式，特指投资产生的收益率，以百分比表示，常用于债券、股票和储蓄等金融语境。

  Investors were pleased with the high yield on their bond portfolio.

  投资者对他们债券投资组合的高收益率感到满意。

• payoff

  Informal, everyday word for the reward or benefit that comes after effort, risk or time invested; not necessarily financial, and often used about personal achievement.

  非正式、日常用词，指经过努力、冒险或时间投入后获得的回报；不一定是金钱上的，常用于个人成就方面。

  All those years of hard work finally had a payoff when she got promoted.

  多年的辛苦努力终于在她获得晋升时得到了回报。

Return, yield and payoff all mean a benefit from investment or effort. Return is the general word for investment profit. Yield is technical, an investment's rate of income. Payoff is informal, a reward after effort or risk, not always money. Other meanings are not compared.

这三个词都可以表示“回报”或“收益”，但 return 泛指从投资或努力中获得的收益，yield 更强调投资的收益率，常用于债券、股息等正式金融语境，而 payoff 强调经过努力或冒险后最终得到的回报，不一定是金钱。这里不比较 return 的“归还”义、yield 的“产量”或“屈服”义，以及 payoff 在其他语境中的“贿赂”义。
