在本文中，我们分析了由两个相距一定距离的相同平面莫尔斯势组成的二自由度势能面中漫游动力学的相空间结构。 Carpenter B K 等人（2018 Regul. Chaotic Dyn. 23 60–79）之前研究过这种势能面，它有两个势阱，周围环绕着不包含临界点的无界平坦区域。我们使用拉格朗日描述符的方法研究了井之间转移的相空间机制。
In this paper, we analyse the phase space structure of the roaming dynamics in a 2 degree of freedom potential energy surface consisting of two identical planar Morse potentials separated by a distance. This potential energy surface was previously studied in Carpenter B K et al (2018 Regul. Chaotic Dyn. 23 60–79), and it has two potential wells surrounded by an unbounded flat region containing no critical points. We study the phase space mechanism for the transference between the wells using the method of Lagrangian descriptors.
