| 单词 | adiabatic approximation |
| 释义 | adiabatic approximation An approximation used in quantum mechanics when the time dependence of parameters, such as the internuclear distance between atoms in a molecule is slowly varying. This approximation means that the solution of the Schrödinger equation at one time goes continuously over to the solution at a later time. This approximation was formulated by Max Born and the Soviet physicist Vladimir Alexandrovich Fock (1898–1974) in 1928. The Born—Oppenheimer approximation is an example of the adiabatic approximation |
