From the derivation, cause and physical significance of the extraphase difference of the coherent field of Gaussian beams can clearly be seen.
从这一导出过程可以清楚地看出高斯束相干场附加位相差的成因及其物理意义。

The modification of the notch filter made the extraphase-shifting introduced to the control system passband reduced and so the control performance was improved.
对陷波滤波器进行了改进，使得引入控制系统通频带的附加相移减小，降低了对系统控制性能的影响。
