分辨率损失 meaning in English

resolution loss

The field distribution and propagation properties in sil system is analysed , and the relationship between the focusing spot size and the defocusing amount is also described . moreover , a novel model is proposed on basis of the fdtd analysis that can make us increase the distance between sil and recording medium without decreasing the recording density
模拟的过程中还发现，在小尺寸sil透镜(半径为波长量级)离焦时，系统焦点可以被推移到离sil底面较远的位置而不会产生大的分辨率损失，根据该结果我们提出了一种增大sil底面与存储介质间距的方案，该方案对于sil高密度光存储系统的实用化研究具有重要意义。
