In the highest clouds, at about -30°F, the vapor crystallizes as long needles or hollow columns. - 当温度通过不同的范围上升时，雪花将会形成平面六角板，其次是空心柱和针头状，然后在25—32度之间又会变回花边六面体。
As the temperatures increase through different ranges, the flakes will form as flat hexagonal plates, followed by hollow columns, needles, and then back to lacy hexagons between 25°F and 32°F. - 在混凝土的用量相等、柱网尺寸相同和相同荷载作用下，对比分析了空心板柱结构和实心板柱结构的抗侧刚度。
With the same column grid network, quantity of concrete and subjected the same loads, the lateral stiffness of the hollow slab-column structures and that of the slab-column structures were compared in the thesis.
