And then the seismic intensity attenuation relations along major axis, minor axis and mean axis are established separately.

研究内容主要包括地震烈度衰减关系和基岩地震动衰减关系。

As the defects produced in its manufacture process, the jumping value of the mean axis was out of the standard during its running, so it gave rise to great vibration of the equipment and stopping.

由于制造缺陷，在设备运行中中间轴跳动值超标，从而引起设备振动大而停机。

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？
