实验测得的后退速度的温度关系可用真空电弧后退运动的正离子喷流模型加以解释。

The experimentally measured temperature dependence of retrograde velocity of vacuum arcs can be explained by the ion jet model for retrograde motion of vacuum arcs.

记得上次在课结尾时我们，尝试计算接近最低点的运动，它看上去似乎静止及后退的趋势。

Remember last time at the end of class we were trying to figure out what exactly happens near the bottom point, when we have this motion that seems to stop and go backwards.

这就是这一建筑作品的从入口开始的全部工作方式，在“前进”与“后退”之间微妙的双重运动中展开。

That is how the building works, from the entrance onwards, in a subtle two-fold movement of advance and retreat.
