本文对广义非线性Schr“odinger方程进行了一阶微扰计算，以研究由这种场论描述的介质所能获得的压缩程度.得到了正常色散区和反常色散区的压缩量表达式。特别地，发现反常色散区的压缩量大于正常色散区。通过保持光场的四阶导数，研究了泵浦光位于零色散波长时的压缩效应。
A first-order perturbation calculation is performed on a generalized nonlinear Schr\"odinger equation in order to investigate the degree of squeezing that can be obtained for a medium described by such a field theory. Expressions for the amount of squeezing in the normal and anomalous dispersion regimes are obtained. In particular, it is found that the amount of squeezing is greater in the anomalous dispersion region than in the normal dispersion region. By keeping fourth-order derivatives in the field, the squeezing when the pump is located at the zero-dispersion wavelength is also investigated.
