v.|boxed;盖住;包起;装箱(encase的过去分词)
"encased"是动词"encase"的过去式和过去分词形式,指某物被完全包裹或封闭在保护性外壳中的状态。根据牛津英语词典(OED),该词源自古法语"encasser",由前缀"en-"(进入)和"caisse"(箱子)组成,字面意为"装入箱中" 。
在具体应用中,encased可描述两种形态:
在专业领域,IEEE标准文件显示高压电缆多采用橡胶包裹("rubber-encased cables")来确保绝缘安全。生物学研究中,Cell期刊曾描述病毒DNA被蛋白质外壳包裹("protein-encased viral DNA")的微观结构特征。
单词encased 是动词encase 的过去分词形式,其核心含义为“完全包裹或封闭某物”,通常指某物被外部材料或结构严密覆盖,形成一个保护层或外壳。以下是详细解析:
The ancient manuscript was encased in glass to prevent damage.
(这份古老的手稿被装在玻璃盒中以防损坏。)
The wires are encased in rubber for insulation.
(电线用橡胶包裹以绝缘。)
The city was encased by thick fog.
(城市被浓雾笼罩。)
Encased 强调“完全封闭”的状态,既可用于具体物体的物理包裹,也可用于抽象概念(如情感、环境)的描述。其核心在于通过外部结构形成保护或隔离效果。
