从信息几何的角度研究了经典理想气体模型.探讨了经典理想气体模型的α-几何结构.借助于几何结构,通过测地弧长、体积元以及Jacobi向量场分析了模型的不稳定性.并且给出了模型的Lyapunov指数.
In this paper,from the viewpoint of information geometry the classical ideal gas model was investigated.Theα-geometric structures of a classical ideal gas model were explored.In virtue of the geometric structures,the instability of the model was studied from the behavior of the geodesic lengths,volume elements and Jacobi vector fields.Finally,the Lyapunov exponent was obtained.
