At low coverage the ethylene molecule occupies approximately the midway between the shortbridge and atop sites.
在低覆盖度下,单个乙烯分子占据了短桥位和顶位之间的中间位置。

The physicists give a simplified example of how this can happen: trying to reach a destination either by using a short but narrow bridge or a longer but wide motorway.
物理学家为此给出了一个简化的例子:通过一座短但窄的桥或者一条宽但长的公路均可到达一个目的地。
