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. 在這種軸流式渦輪機中，蒸汽總是沿主軸的旋轉軸流動的，因此，葉片由主軸向外呈輻射狀展開。
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. 在研究過程中，我們先在幾何學方面通過研究椎管容量來模擬不同的旋轉軸。
The earth rotates once a day on its axis. 地球繞它的自轉軸一天旋轉一周。
Material along the rotation axis falls vertically toward the equatorial plane much faster. 沿著轉軸兩側分佈的物質則快速筆直地落入赤道面。
