摘要
利用含时Ｈａｒｔｒｅｅ 近似法得到色散缓变光纤的量子非线性薛定格方程，在一定条件下，有量子态的孤子解，并由此方程讨论经典和量子效应对孤子传输的影响，由此我们进一步发现，光场算符的量子力学的平均值是一系列修正的经典孤子的选加，色散缓解应等效为一个长距离分布参数的光纤放大器，导致非线性效应增加。
We use the time dependent Hartree approximation to obtain solutions to a quantitative nonlinear Schrodinger equation(NLS) in a dispersion slowly decreasing fiber,It describes optical pulses propagating in fibers,and under certain conditions quantum state soliton solutions exist,and the solution for influence of soliton propagation as well as classical and quantum effects are discussed in detail.Further we find that mean value of the ifield in fiber is the pile up of a series of classical sotions with corrections.And the effect of slowly decreasing dispersion equivalent a long distance dispersed parameter fiber amplifier,that lead to nonlinear effect increase,the solitons by compression in fiber.
