椭圆形

The formulae of each meridian of the corneal anterior surface are ellipses, and the asphericity of the horizontal or near-horizontal meridians are prolate ellipses.

In general, the deformation pattern of ellipse shaped shell in dieless spinning is similar to that of a rotary one. Therefore, it is possible to spin a deep elliptic cylindrical shell if a cylindroid mandrel is adopted.

从总体上看，椭圆形锥壳零件的无芯模旋压和回转形锥壳无芯模旋压的变形规律相类似，由此可以推测，利用椭圆柱形芯模实现椭圆形深筒零件的旋压也是可能的。

Leaf blade elliptic or ovate-elliptic; peduncle very short; each cyme 2-4 × branched; thorns erect.

An elliptical parabola with the same dimensions would have smaller gain by about 1 dB in relation to this analyzed rectangular, with the same efficiency, because of smaller geometric surface of the elliptic parabola.

一个同样尺寸，同样效率的椭圆形抛物线反射器，比这个长方形反射器低大约1dB的增益，这是由于椭圆形抛物面几何表面小一些。

But now, drawing back to the edge of the table, gradually lower your eye (thus bringing yourself more and more into the condition of the inhabitants of Flatland), and you will find the penny becoming more and more oval to your view, and at last when you have placed your eye exactly on the edge of the table (so that you are, as it were, actually a Flatlander) the penny will then have ceased to appear oval at all, and will have become, so far as you can see, a straight line.

但是，现在，向桌子的边缘靠下去，你的视线逐渐降低（这样可以使你越来越进入平面国居民的状态）。你会发现这枚硬币逐渐变成了椭圆形，并且越来越扁，最后，当你的眼睛正正好在桌子边缘的时候（这样你就是，就好象是，真正的平面国国民了），这枚硬币不再呈现出椭圆形，正如你所看到的，它已经变成直线了。
