Luminiferous Medium / 发光介质

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibration, and, at a later stage, to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.
为了解释光学现象,人们曾经试图假定存在一种具有与弹性固体物理性质相同的介质。这种尝试的结果,最初曾使人们了解到一种能传输横向震动的介质的具体实例,但后来却使人们得出了这样一个明确的结论:并不存在任何具有上述假定所认为的那种物理性质的发光介质。
