The structure of the isochromatic fringe pattern in a two-dimensional photoelastic model is investigated with the phase diagram method of the theory of dynamic systems. Isochromatics are interpreted as phase paths (or level curves) of a Hamiltonian system. Possible singularities of the fringe pattern are analyzed.
利用动力系统理论的相图方法研究了二维光弹性模型中等色条纹图案的结构。等色线被解释为哈密顿系统的相路径（或水平曲线）。分析了条纹图案可能的奇点。
