We examine patterns of absorption intensity in two-mode systems with a 2:1 Fermi resonance in an intensity model based on the effective fitting Hamiltonian. We relate these patterns to the Fermi resonance phase space structure and catastrophe map. Each of the four zones of the catastrophe map has a phase sphere structure with a certain number of distinct regions. For each zone, we find that for every region on the sphere, there is a distinct region in the intensity pattern.
我们在基于有效拟合哈密顿量的强度模型中，研究了具有 2:1 费米共振的双模系统的吸收强度模式。我们将这些模式与费米共振相空间结构和突变图相关联。突变图的四个区域中的每一个都具有一定数量的不同区域的相球结构。对于每个区域，我们发现对于球面上的每个区域，在强度模式中都有一个独特的区域。
