coupling constant造句

Classical and quantum oscillators of quartic anharmonicity are solved analytically up to the second power of (weak-coupling constant) by using the multiple-scale perturbation theory.

The results indicate: the effective mass of an acoustical polaron undergoes a sudden increasing when thee-p coupling constant achieves the critical value and then the self-trapping occurs.

Some discussions of the calculated results and the factors which affect the coupling constants are also reported.
