So, if you slice these things by a vertical plane, or actually even better, a vertical half plane, something to delete one half of the picture.

如果你画个切面是垂直的，或者是更好的垂直半平面，我们擦掉这半边。

By using of complex variable function and integral equation method, the antiplane multiple holes and cracks problem of half plane region is considered in this paper.

Yes? Yeah, so I'm saying when you fix theta you get only a half plane, not a full plane I mean, it goes all the way up and down, but it doesn't go back to the other side of the z axis. Why?

请说，所以我说当固定θ时,得到的是半平面，而非全平面,它布满z-轴的一侧,但从不延伸到z-轴的另一侧，为什么？

As he later described it, the plane was not much more than half a kilometer above the trees.
