中文翻译与英英解释

	【物理学】微粒说。

	emission: n. 1.(光、热、气体等的)发出，发射，射出，放射；传 ...
	theory: n. 1.理论，学理，原理。 2.学说，论说 (opp. ...

Emission theory (also called emitter theory or ballistic theory of light) was a competing theory for the special theory of relativity, explaining the results of the Michelson-Morley experiment. Emission theories obey the principle of relativity by having no preferred frame for light transmission, but say that light is emitted at speed "c" relative to its source instead of applying the invariance postulate.
