该方案采用三波门跟踪，通过偏差计算电路和反馈控制电路使中间波门中心始终对准目标回波脉冲中心，完成距离跟踪。

The scheme accomplishes range tracking by adopting three range gate tracking to make middle gate always centered at echo pulse center through feedback circuit and deviation calculation circuit.

她住在以法莲山地拉玛和伯特利中间，在底波拉的棕树下。以色列人都上她那里去听判断。

And she dwelt under the palm tree of Deborah between Ramah and Bethel in mount Ephraim: and the children of Israel came up to her for judgment.

要避免枯燥无聊——不仅是作者本人的也是观众的——故事的中间情节必须一波三折。

To avoid boredom — both the writer's as well as that of the audience — plot twists and turns will be introduced in the middle of the story.

If we overlay what the actual molecular orbital is on top of it, what you see is that in the center you end up cancelling out the wave function entirely.

如果我们把真实的分子轨道覆盖在上面，你可以看到中间的,波函数是完全抵消掉了。

We're seeing that the wave function's adding together and giving us more wave function in the center here.

我们看到波函数加在一起,使中间的波函数更多了。

So instead, these would be canceling out wave functions between the two, so we would end up with a nodal plane down the center.

相反，两者之间的,波函数会相互抵消，所以我们在中间会得到一个节面。
