轴线

The axis of a circle is its diameter.

圆轴线是其直径。

This bar of palm trees creates the primary axis of the site, an allee into the inner courtyard of the media square.

这片棕榈林是城区轴线，一条引导人们进入媒广场内院小径。

Through 16 spatial series embodying the Olympic spirit and sports, the theme axis is built up to express human spiritual activities ascending in spires and subliming.

16奥运精神运动主题空间,联结成一条表达人类精神活动螺旋上升、直至升华主题轴线。
