phase distribution of field的意思|示意

Undulator rms phase error is expressed as function of the magnet peak field distribution. It can be used as the objective function for practical undulator performance optimization.

给出了波荡器位相误差的函数式，可由磁场峰值分布直接计算波荡器位相均方根误差。

At the same time, because of the influence of light-field squeezing effect, the phase probability distribution is different from that of coherent-state field.

同时由于光场压缩效应的影响使相位概率分布呈现出与相干态光场所不同的情况。

The centroid position of the focal spot directly depending on intensity distribution and phase slope distribution of near field is derived and its physical meaning is described.

进一步推导了焦斑质心位置对光束近场强度分布和相位斜率分布的依赖关系式，并对该式清晰的物理意义进行了阐述。
