摘　　要：利用P─B位相理论，解决了谐振条件下的三能级∧原子对光场位相及其函数期望值的影响问题。由于原子的作用，使得光场位相涨落一般随时间增大，光场位相─光子数一般不再保持最小测不准关系。而且光场位相的正、余弦函数的涨落也具有同样结论。Using P-B phase theory, in resonant condition, the influence of the three-levelatom on the phase of the field and on the expective values of the phase function is given. Due tothe action of the atom, the fluctution of the phase is increased with time evolution ,the relation between the phase and the photon number does not maintain the minimum uncertainty relation.And the fluctuation of the sine and cosine functions of the phase has the same conclusion.
