摘要
提出全同粒子模型进一步解释视网膜与视皮层之间的联系,根据辐射与物质相互作用的时间量子理论研究全同粒子系统的辐射跃迁.模型显示,全同粒子系统的亚辐射态对外界没有响应,超辐射态的辐射跃迁几率是粒子数的非线性函数.对视觉细胞与视色素各自的相干性和视觉明暗适应中视网膜与视皮层之间协同作用的初步解释支持全同粒子模型.因此,全同粒子模型对视觉适应成立,它与Retinex理论的结合将为视觉适应的进一步研究提供新的线索.
The retina and cortex are correlated by the identical particle model. The vision system is modeled as identical particle system, and its radiation transition is studied by using time quantum theory of radiation-matter interaction. The identical particles form coherent states, the transition probability of the superradiant state is a liner function of N2 and N3 (N is the particle number) ,and the one of the subradiant state is zero,which is supported by its successful primary explanation of the coherence of vision cells and pigments,respectively, and the co-action of retina and cortex in the vision adaptation of darkness and brightness. Identical particle model might hold for vision adaptation, and its further integration with Retinex theory will give a clue for the further research of vision adaptation.
