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。
The earth rotates once a day on its axis. 地球绕它的自转轴一天旋转一周。
Material along the rotation axis falls vertically toward the equatorial plane much faster. 沿著转轴两侧分布的物质则快速笔直地落入赤道面。
