1·Ball nut, a fixed spherical nut driven by the jackscrew for flap and stabilizer movement.
球形螺母，由顶头螺钉驱动的固定球形螺母，用于翻板和稳定器运动。
2·There could be any number of reasons this could happen: the models for the gas assume it's spherical and smooth when it may be neither, for example.
这种情况能够发生，一定有很多原因：比如，用于气体估算的模型是球形的，同时也是光滑的，但是气体可能不具有这两个特征。
3·Some species simply live in the dung, while others form perfectly spherical dung balls, which they roll with their hind legs, often over large distances, to a place where they can bury it.
部分蜣螂干脆居住在粪便当中，其他蜣螂用自己的后足将粪便滚成完美的球形，进行距离的运输，直到到达它们埋藏粪球的地方。
4·These electrons get funnelled into a metal spherical receiver to produce a current, which generates the wire's magnetic field - making the system self-sustaining.
这些电子被引入一个球形金属收集器以产生电流，继而产生线圈的磁场——这样这个系统就可以自我维持了。
5·Among the remains, the team noticed a spherical bone, called a basioccipital condyle, found in all mammals and reptiles that joins the base of the skull to the spinal cord.
该团队在遗骨中发现一个称为枕骨髁的球形骨，这是所有哺乳动物和爬行动物身体中连接颅底和脊髓的部分。
