wave front aberration meaning in English

波陈面像差
波前像差

The relationship between wave - front aberration and focal spot size was researched roundly , and the essential connection between focal spot energy shape and wave front gradient distribution was discovered , and a smarter parameter to evaluate wave front aberration was founded . based on this , the wave front aberration tolerance confined by focal spot size requirement was obtained through calculation and statistics method . 2
比较全面地分析了系统内部波前误差与光束焦斑尺寸之间的关系，找到了波前梯度分布与焦斑能量分布之间的本质联系，提出了一个与焦斑尺寸关系最密切的波前误差参数，并采用数值模拟和统计的方法得到了焦斑尺寸限制条件所要求的波前误差限制条件； 2
