中文摘要	首先阐述了将渐变折射率薄膜细分为多层均匀薄膜的分层介质理论，接着给出了一种获得最佳分层数目的分层评价方法，最后以线性变化渐变折射率薄膜为例说明了如何优化获得渐变折射率薄膜的分层数目．研究发现：渐变折射率薄膜的分层数目与薄膜的厚度和薄膜的折射率变化快慢有关，在一定的折射率变化范围内，渐变折射率薄膜的分层数目随着薄膜厚度的增加先减小后增大．; Optical property analysis and preparation of graded index coatings can be approximated by subdividing it into a stack of many homogeneous layers. In this paper, layered medium theory is introduced firstly, which clarifies how to subdivide graded index coatings into homogeneous layers. Then a stratification merit method to get optimal layered number is put forward. At last, linear graded index coatings is taken as an example to illustrate how to obtain the optimal layer number of graded index coatings. Our discussion shows that the optimal layer number of graded index coatings depends on the coating thickness and changing speed of refractive index. When refractive index changes in given range, the layer number of graded index coatings decreases firstly and then increases with the increasing coating thickness.
