rotational axis的用法和样例：
例句
- In this axial turbine, steam always flows along the axis of rotated axis, thus, all blades extend with the radiation shape along the axis outward.
在这种轴流式涡轮机中，蒸汽总是沿主轴的旋转轴流动的，因此，叶片由主轴向外呈辐射状展开。 - First, we examined the problem from a geometrical point of iew then we modeled the different rotational axes by studying the change in olume of the spinal canal.
在研究过程中，我们先在几何学方面通过研究椎管容量来模拟不同的旋转轴。
