摘　　要：本文利用Ｌｅｗｉｓ－Ｒｉｅｓｅｎｆｅｌｄ的量子不变量理论，求出了单频双光子过程的精确解，研究了此精确解的绝热渐近极限，求出了双光子过程在量子绝热情形下的Ｂｅｒｒｙ相因数。In this paper the exact solution to the time-dependent single frequency two-photonprocess is discussed by using the theory of invariants of Lewis and Riesenfeld. The adiabaticapproach of the exact soltition is disctissed and the Berry phase of the process is obtained inthe case of quantum adiabatic process.
