误差叠加 meaning in English

series of tolerances

The wave - front aberration ' s cumulating of optics elements in multi - pass amplifying system was researched more deeply . considering the correlation between optics elements " wave - front aberrations caused by the similar fabrication technique , the correlation coefficient was adopted to revise calculation rule of superimposition which used in estimating system ' s static wave - front aberration and allocating optical machining precision . 3
进一步研究了多程放大系统中光学元件波前误差的叠加规律，并考虑到钕玻璃片加工工艺的相似性所导致的波前相关性，将相关系数耦合到波前误差叠加公式中，使修正后的公式能更准确地预估系统静态波前和分配光学元件加工精度要求； 3
