Exsuse me? Fine. You can be in charge. You fix the plane.

你说什么?好吧，你负责，你来修飞机。

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？

youdao

Can you get a fix on the plane?

你能给飞机定位吗？
