The experimental evidences show that both actions of doubleexchangeinteraction and small polarons are responsible for the variation of the CMR effect.
实验结果表明，是双交换作用和小极化子效应的共同作用决定了CMR效应的特性。

The dynamic problem of interaction between a 2-level atom and double modes field is analyzed. It dealt with the process of exchange of momentum between the field and the atom.
