It has been proved that induced voltage causes a current to flow in opposition to the force producing it.
已经证明，感应电压使电流的方向与产生电流的磁场力方向相反。
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 vibrations, 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，人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种尝试最初曾使人们理解一种能传输横向振动的介质的具体例证。后来则得出确切的结论即并没有假定中设想的有该物理特性的发光介质。
