范德瓦尔斯方程中的分岔与混沌

摘要

Found by numerical iterative calculation, for van der Waals equation, the evolution of molar volume with the pressure is from period doubling bifurcation to chaos When the temperature takes proper values, the Feigenbaum bifurcation diagram and Lyapunov exponent in the evolution are given.%通过数值迭代计算发现,当温度取适当值时范德瓦尔斯方程中的摩尔体积随压强的演化表现为从周期倍增分岔通向混沌,并给出了该演化过程的费根鲍姆分岔图及李雅普诺夫指数.
