aether    
n. 醚,以太,上空

醚,乙太,上空

Aether
n 1: personification of the sky or upper air breathed by the
Olympians; son of Erebus and night or of Chaos and darkness
2: a medium that was once supposed to fill all space and to
support the propagation of electromagnetic waves [synonym:
{ether}, {aether}]

AEther \[AE]"ther\, n.
See {Ether}.
[1913 Webster]


Ether \E"ther\ ([=e]"th[~e]r), n. [L. aether, Gr. a'iqh`r, fr.
a'i`qein to light up, kindle, burn, blaze; akin to Skr. idh,
indh, and prob. to E. idle: cf. F. ['e]ther.] [Written also
{[ae]ther}.]
1. (Physics) A medium of great elasticity and extreme
tenuity, once supposed to pervade all space, the interior
of solid bodies not excepted, and to be the medium of
transmission of light and heat; hence often called
{luminiferous ether}. It is no longer believed that such a
medium is required for the transmission of electromagnetic
waves; the modern use of the term is mostly a figurative
term for {empty space}, or for literary effect, and not
intended to imply the actual existence of a physical
medium. However. modern cosmological theories based on
quantum field theory do not rule out the possibility that
the inherent energy of the vacuum is greater than zero, in
which case the concept of an ether pervading the vacuum
may have more than metaphoric meaning.
[1913 Webster PJC]

2. Supposed matter above the air; the air itself.
[1913 Webster]

3. (Chem.)
(a) A light, volatile, mobile, inflammable liquid,
{(C2H5)2O}, of a characteristic aromatic odor,
obtained by the distillation of alcohol with sulphuric
acid, and hence called also {sulphuric ether}. It is a
powerful solvent of fats, resins, and pyroxylin, but
finds its chief use as an an[ae]sthetic. Commonly
called {ethyl ether} to distinguish it from other
ethers, and also {ethyl oxide}.
(b) Any similar compound in which an oxygen atom is bound
to two different carbon atoms, each of which is part
of an organic radical; as, amyl ether; valeric ether;
methyl ethyl ether. The general formular for an ether
is {ROR'}, in which R and R' are organic radicals
which may be of similar or different structure. If R
and R' are different parts of the same organic
radical, the structure forms a cyclic ether.
[1913 Webster PJC]

{Complex ether}, {Mixed ether} (Chem.), an ether in which the
ether oxygen is attached to two radicals having different
structures; as, ethyl methyl ether, {C2H5.O.CH3}.

{Compound ether} (Chem.), an ethereal salt or a salt of some
hydrocarbon as the base; an ester.

{Ether engine} (Mach.), a condensing engine like a steam
engine, but operated by the vapor of ether instead of by
steam.
[1913 Webster]

    “以太”一词是英文Ether或Aether的音译。 古希腊人以其泛指青天或上层大气。 以太也被认为是第五元素,在亚里士多德看来,物质元素除了水、火、气、土之外,还有一种居于天空上层的以太。 在科学史上,它起初带有一种神秘色彩。
  • 以太 - 维基百科,自由的百科全书
    以太 (英語: Luminiferous aether)或譯為 光乙太, 以太 (英語: aether)原本是 古希腊 哲学家 亞里斯多德 所设想的一种物质,為 五元素 之一。 19世紀的物理學家,認為它是一種曾被假想的 電磁波 的傳播介質 [1]。 但後來的实验和理论表明,如果不假定“以太”的存在,很多 物理 现象可以有更为简单的解释。 也就是说,没有任何观测证据表明“以太”存在,因此“以太”理论被科学界抛弃。 19世纪,科学家们逐步发现 光 是一种波,而生活中的波大多需要传播介质(如 声波 的传递需要借助于 空气,水波的传播借助于 水 等)。 受 经典力学 思想影响,于是他们便假想宇宙到处都存在着一种称之为以太的物质,是这种物质作為光的传播中的 介质。
