比较义项：需求（名词）。

• requirement

  Refers to a condition that is officially needed or demanded, often set by rules, institutions or a process; collocates with 'meet', 'a requirement for/of'.

  指官方或制度上需要或要求满足的条件，常与规则、机构或流程相关；常见搭配为 meet a requirement、a requirement for/of。

  Passing the exam is a requirement for graduating this year.

  通过考试是今年毕业的一项必要条件。

• demand 本词

  Refers to people's desire or need to have or buy something, especially in an economic or market context; collocates with 'high/low demand for'.

  指人们想要拥有或购买某物的愿望或需要，尤其用于经济或市场语境；常见搭配为 high/low demand for。

  There is a high demand for skilled workers here.

  这里对熟练工人的需求量很大。

Requirement and demand both mean a need for something. Requirement is a condition officially needed, often set by rules or institutions. Demand is people's desire to have or buy something, especially in economic or market contexts. Demand as a verb is not compared.

这两个词都表示对某事物的“需求”，但 requirement 强调官方或制度上规定必须满足的条件，语气客观、正式；demand 强调人们想要或渴望得到某物的欲望，常用于市场或供需语境。这里不比较 demand 的“要求，强硬索求”这一动词义项及其相关名词用法。
