求翻译：分析空间频率不变的情况下，波前误差峰谷（P-V）值的改变会使光束质量怎么样的变化，以及分析波前误差峰谷（P-V）值不变的情况下，改变空间频率对光束质量的影响。是什么意思？

Unchanged by the analysis of spatial frequency wavefront error of peak-valley (pv) values ​​of the change will make the beam quality of how change, as well as analysis of wavefront error of peak and valley (pv) value of the same case, changing the spatial frequency beam quality.

Analysis of the space rate does not change the circumstances, the wave front error peaks and troughs (P - V) value of the change so that the beam quality is what kind of changes, as well as the wave front error analysis peak (P - V) value does not change, and change the spatial frequency of the beam
