查询词典 parabolas

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。

Does such 定点 also exist in parabolas, eclipses, and hyperbolas?

是否在抛物线、椭圆、双曲线同样也存在这样的定点？

Open curves such as parabolas, hyperbolas, and spiral s have infinite length

拋物线、双曲线、螺线属于开放曲线，其长度无限

Open curves such as parabolas, hyperbolas, and spirals have infinite length

From 1957 to 1963, the design team went through at least twelve iterations of the form of the shells trying to find an economically acceptable form (including schemes with parabolas, circular ribs and ellipsoids) before a workable solution was completed.

从1957年到1963年，设计队伍反复尝试了12种不同的建造&壳&的方法（包括抛物线结构，圆形肋骨和椭圆体），最后终于找到一个经济上可以接受的解决方案。

When SAT TV offset parabolas are used, focus is determined by the position of the SAT TV converter.

当使用卫星电视偏馈抛物面天线时，焦点被限定在卫星电视变频器的位置。

And in parabola-aligned images, we find that using the combination of two parabolas as the projection axis can segment teeth more precisely.

我们事先收集了一些样本，以统计的方式估计出牙齿的大小、银粉与非银粉间的颜色分布情况。

When SAT TV offset parabolas are used, focus is determinate by the position of the SAT TV converter.

当使用卫星电视偏馈抛物面天线时，焦点限定在卫星电视变频器的位置。

Optimizing the model results in location the two edges of road which is represented as a vectorgraph by the parameter of parallel parabolas.

该模型的优化过程实现了道路的定位，得到的结果是平行抛物线的参数，实现了道路的矢量表示。

However, if you want to use the cheap production of SAT TV offset parabolas for the work on 13cm Ham band or WLAN frequencies; you have to try to construct the feed that matches existing parabolas.

无论如何，如果你想用一个低制作成本的卫星电视偏馈抛物面天线，工作于13厘米的业余无线电频段或者WLAN波段，你必须制作一个与现有抛物面反射器相配的馈源。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
