释义	excited state noun : a state of a physical system (such as an atomic nucleus, an atom, or a molecule) that is higher in energy than the ground state Example Sentences Recent Examples on the Web The quasiparticles are expected to quickly lose energy and so won't be able to transfer enough to raise a qubit from its ground state to its excited state. John Timmer, Ars Technica, 14 Dec. 2021 Vilke said that people in Prude’s excited state often die with or without restraint, and that being restrained from further exertion had actually helped him.

Paul Halpern, Scientific American, 18 Aug. 2021 The system transitions by passing through a mixture of the excited state and ground state, a quantum phenomenon known as superposition. Eleni Petrakou, Scientific American, 29 Dec. 2020 Thorium-229 is special among isotopes because of the extremely low energy of its lowest excited state, meaning it’s the best candidate for a measurable standard that can be used to make a practical clock. Caroline Delbert, Popular Mechanics, 12 Oct. 2020 All the excess electrons knock the plasma molecules into an excited state, which then emit photons to produce that telltale glow. Jennifer Ouellette, Ars Technica, 20 Aug. 2020 Related Stories Several years ago, researchers began to make these diodes using copper in a similar excited state to the way precious metals work in PHOLEDs. Caroline Delbert, Popular Mechanics, 5 May 2020 Our current understanding of the triple-alpha process largely came from astronomer Fred Hoyle, who famously predicted, in 1954, that a special excited state of carbon-12 must arise during synthesis .
