求翻译：得出结论：在空间频率不变的情况下，光束质量随着波前误差P-V值增大而增强；在波前误差P-V值不变的情况下，光束质量随着空间频率的增大而变弱。是什么意思？

Concluded that: in the case of constant spatial frequency, beam quality is enhanced with the increase of the wavefront error pv value; in the case of the same wavefront error pv value, the beam quality change with the increase of spatial frequency is weak.

Come to the conclusion: the spatial frequency is not the case, the beam quality as the wave front error P - V value is increased and strengthened; in the wave front error P - V values do not change the circumstances, the beam quality as spatial frequency increases.

Draws the conclusion: In the spatial frequency invariable situation, the light beam quality increases along with the wavefront error P-V value strengthens; In the wavefront error P-V value invariable situation, the light beam quality increases along with the spatial frequency changes weak.
