比较义项:覆盖或构成表面的一层材料(名词)。

  • layer 本词

    General everyday word for a layer of any material; used casually or technically, and commonly paired with verbs like add, peel off, or remove.

    layer 是日常通用词,可以指任何材料的一层,可用于随意或专业语境,常与 add(加)、peel off(剥掉)、remove(去掉)等动词搭配。

    She added another layer of blanket to stay warm at night.

    为了在夜里保暖,她又加了一层毯子。

  • stratum

    Formal, technical word almost exclusively used in geology for a distinct layer of rock or soil; plural is strata, and it sounds odd applied to everyday materials.

    stratum 是正式、专业的词,几乎只用于地质学中指岩石或土壤的一层,复数为 strata;用在毯子等日常材料上会显得很奇怪。

    Each stratum of rock revealed a different period of history.

    每一层岩层都揭示了不同的历史时期。

Layer and stratum both mean one level of material. Layer is the everyday word for any material, used casually or technically. Stratum is formal and technical, used mainly in geology for a rock layer, plural strata. Not compared: stratum meaning a social class.

这两个词都表示“层”,但 layer 是日常通用词,可以指任何材料的一层,语域随意;stratum 是较为正式、专业的词,几乎只用于地质学中指岩石的一层,复数为 strata。这里不比较 stratum 表示“阶层”(社会阶层)的比喻义。
