According to time distribution of Al Ⅰ396.15 nm emission in the plasma induced by laser ablating Aluminum, based on quantum mechanics, we have suggested a hypothesis of transient steady state of atom, which could give our experimental results overall and reasonable explanation in quantum. We suggested that there should be a certain atomic state between ground and excited state of Aluminum atom, so called transient steady state. The transient steady state was that aluminum atom had already absorbed a certain photon, but the valence electron had not transited to external orbit. That is to say, aluminum atom had not transited into excited state, but changed into a certain state called transient steady state between ground and excited state. Seen from the point of atomic energy level, the transient steady state is identical to the level of excited state. The transient steady state was one of the most important models storing energy. The hypothesis could roundly and reasonably explain our experimental results.
