1. Femoral lateral arcs are parabolas. 股骨内侧弧的曲线是抛物线。
2. Upswept roofs and parabolas cropped up on buildings. 建筑物采用了倾斜的抛物线屋顶。
3. Parabolas have been studied for millennia, and their properties are well understood. 人类已经研究了抛物线近千年,对它的性质理解的很透彻。
4. The relationship between mean of CT number and variance of CT number to axial deformation are parabolas. CT数的均值、方差随轴向变形变化关系曲线呈抛物线形式。
5. Now according to Newtonian theory, some of them moved in hyperbolas or parabolas never to return; others moved in ordinary ellipses. 现在,牛顿理论认为,有一些彗星沿双曲线或抛物线运行,永远不再返回;另外一些彗星沿普通的椭圆轨道运行。
