Compared meaning: the act of rubbing or wiping a surface (noun).

比较义项：用手或布在物体表面上摩擦/擦拭的动作（名词）。

• rub 本词

  Describes a firm, often repeated back-and-forth motion; not necessarily meant to clean, and can be applied to skin, sore muscles, or any surface for friction or relief.

  指用力、通常反复的来回摩擦动作；不一定是为了清洁，也可以用在皮肤、酸痛的部位或任何表面上，以产生摩擦或缓解不适。

  She gave her sore shoulder a quick rub to ease the pain.

  她快速揉了揉酸痛的肩膀，以缓解疼痛。

• wipe

  Describes a brief motion, usually with a cloth or hand, aimed at cleaning or removing dirt, dust, or liquid from a surface.

  指通常用布或手进行的短促动作，目的是清除表面上的灰尘、污渍或水渍，以达到清洁效果。

  He gave the counter a quick wipe with a damp cloth.

  他用湿布快速擦了一下台面。

Both words describe a hand or cloth moving on a surface. Rub stresses a firm, repeated motion, not always for cleaning; it can also touch skin or sore muscles. Wipe stresses a brief motion with a cloth, meant to remove dirt or liquid, cleaning it.

这两个词都可以指用手或布在表面上来回移动的动作，但语气和目的不同：rub强调用力、反复的摩擦，不一定是为了清洁，也常用在皮肤、酸痛部位等地方；wipe则强调为了清除表面的灰尘、污渍或水渍而做的短促擦拭，目的通常是清洁。这里不比较 rub 和 wipe 作动词使用时的其他义项。
