vacuum词源中文解释

1540年代,“空间的空虚”,源自拉丁语 vacuum “空的空间,空位,空虚”,中性形式的名词 vacuus “空的,未被占用的,缺乏的”,比喻意义上是“自由的,未被占用的”,源自原始意大利语 *wakowos,与拉丁语 vacare “空着”(源自 PIE *wak-, 是 *eue- “离开,放弃,放出”的扩展形式)有关,带有形容词后缀 -uus。它是希腊语 kenon “空的东西”的借译。

1650年代,“空气被排空的空间”的意思得到证实。1859年,出现了 Vacuum tube “玻璃热电子器件”。1903年,出现了 Vacuum cleaner,缩写形式 vacuum(名词)首次记录于1910年。

The metaphysicians of Elea, Parmenides and Melissus, started the notion that a vacuum was impossible, and this became a favorite doctrine with Aristotle. All the scholastics upheld the maxim that "nature abhors a vacuum." [Century Dictionary]
