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(dòng)的，因此，葉片由主軸向外呈輻射狀展開(kāi)。
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(guò)程中，我們先在幾何學(xué)方面通過(guò)研究椎管容量來(lái)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(zhù)轉軸兩側分布的物質(zhì)則快速筆直地落入赤道面。
