摘要
本文直接对电磁场进行量子化，用密度矩阵描述光纤中的孤子，从量子光学的主方程出发推出Ｐ表示的福克－普朗克方程，从而引出量子包络孤子在光纤中传输的准经典的非线性薛定谔方程，最后介绍了方程的应用。
The electromagnetic field is quantized, the envelope soliton is discribed by the density matrix. The Fokker-Planck equation of P representation is drawn from master equation in quantum optics. The quasiclassical nonlinear Schrodinger eguation is introduced for soliton envelope in an optical fiber. The application of the equation is discussed.
