结果表明高功率微波的有质动力将影响微波色散特性，使微波场强分布偏离Bessel分布，并对等离子体有排开作用，当场强足够大时可将波导中心处等离子体排空形成低密度通道。

It is shown that transmission performance which uses postcompensation is superior to that uses precompensation and it can be concluded that the postcompensation should be used for dispersion compensation in long-haul, high-capacity optical transmission in the case of the nonlinear effects.

对基于RZ的400b／s常规单模光纤传输系统进行了仿真，该系统的色散补偿分别采用前置补偿和后置补偿，结果发现在存在非线性情况下，其色散补偿采用后置补偿的传输性能明显优于采用前置补偿的传输性能。

In conventional seismic data processing, the earth is regarded as prefectly elastic medium.However,the pores of stratum rock often contain fluid. So, when the seismic wave propagates in it, there are energy attenuation and phase distortion related to frequency. Moreover, the attenuation, scattering,and dispersion of high-frequency components are far higher than that of low-frequency components.
