vacuum

Compared meaning: an empty space with nothing in it (noun).

比较义项：真空／空无一物的空间（名词）。

• vacuum 本词

  Vacuum is the precise scientific term for a space with no air or matter at all, used for physical phenomena like outer space or sealed containers; it is neutral, technical language, never emotional.

  vacuum 是科学意义上的精确说法，指完全没有空气或物质的空间，用于描述外太空或密封容器等物理现象；语气中性、专业，从不用来形容情感。

  The container was sealed tightly to create a vacuum with no air inside.

  这个容器被密封起来，制造出一个没有空气的真空。

• void

  Void is a more literary word for a vast, empty space, often used figuratively for silence, darkness, or emotional emptiness rather than the strict scientific absence of matter.

  void 是较为文学化的词，形容广阔而空荡的空间，常用来比喻寂静、黑暗或内心的空虚，而不是强调科学意义上物质的缺失。

  Losing her felt like staring into an endless, empty void.

  失去她的感觉，就像凝视着一片无边无际的空虚。

Vacuum and void both mean an empty space with nothing in it. Vacuum is the neutral scientific term for emptiness, like outer space. Void is more literary, often figurative for a vast emptiness. It does not compare vacuum as a verb, or void as 'invalid'.

这两个词都可以指“空无一物的空间”，但语域和用法不同：vacuum 是科学、中性的说法，强调完全没有空气或物质；void 更文学化，常用来比喻浩瀚、令人不安的空虚，或内心的空虚感。这里不比较 vacuum 作动词“用吸尘器打扫”的用法，也不比较 void 作形容词“（合同等）无效的”的用法。
