抛物面

A new method to align the optical axis of parabolic mirrors is introduced.

介绍了一种确定抛物面反射镜光轴的新方法。

There are also parabolic antennas modified to transmitters.

这也有对传输器的抛物面天线改造。

Efficiency and gain of a parabolic antenna directly depend on the degree of accomplishing of these demands.

抛物面天线的效率和增益完全取决于实现这些要求的程度。

Through studying the intersection of paraboloid of revolution and cylinder , the author concluded that the horizontal projection of the intersecting lines—, is the famous Four-order algebra curve-Perseus curve.

通过对回转抛物面与圆柱面相交的研究，得出交线的水平投影曲线——为四次代数曲线——Perseus座曲线的结论。

An intelligent paraboloid truss antenna is designed and its dynamic model is presented by means of finite element method.

摘要设计了一个智能抛物面桁架天线，采用有限元方法得到了它的动力学模型。

What I mean is, comparing to the best fit paraboloid, the edge of your mirror has been down by 1/9 wave.

我是说，与最佳的相合抛物面比较，你的镜子的边缘是向下 1/9 波。

The paper gives a detailed analysis of the working principle and suggests a theory of gas velocity deflection of paraboloid.

文中详细分析了这种陀螺的工作原理，提出了管内速流偏心抛物面理论，并以此为基础建立了较完整的理论，纠正了传统理论中的某些错误。

Here we use the hypothesis own to overcome theresult that the tangent paraboloid we constructed only half in t.

我们这里用这一假设，主要是用于克服切抛物面关于t方向只有一部分这一困难。

An f/10 paraboloid's sweet spot, by contrast, spans 22 mm (0.87 inch).

一个f/10的抛物面镜的甜点，扩展到22mm。

If you fugure the mirror with this pinhole you will get a paraboloid suffering 1/20 wave PV undercorrected.

如果你修磨这反射镜采用此针孔，你会得出壹个抛物面蒙受了 1/20 波 PV 修正不足。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
