Comment: "I agree w/ "分界". Your ref. is classical mechanics, just as I indicated in the subtitle. "

分界线
在非欧几何里，分界线不能以二维、三维来理解，所以“线”并非欧氏几何里所说的“两点之间最近的距离是直线”里的“线”，而是在四维相位空间里形成的线，因此它当然不会是 a (border) line，而是 an (border) x-trix。但理解上还是可以称之为“分界线”。
我还没找到别人的译法，晚些再查找。

这东西当然也有可能看不见，或是转成二维、三维的图像看起来不像“线”，和 tori 的情况一样，看得见的只是 mappings in 2-dimensional plane or in 3-dimensional space。

摆幅或振幅
原文讲是区分振动或摆动的界线，那应该是指摆幅或振幅
Note from asker:
| Thank you, happyzane. The angle variable of libration is finite, say [-Pi, Pi], while the angle of rotation is not. Please see, e.g., http://en.wikipedia.org/wiki/Separatrix_(dynamical_systems), esp. the figure with the separatrix in red. |
