查询词典 radius

This paper de-duces the equation of scroll case surface with the enveloping theory,builds the envelope sur-face of ellipsoides with variable radius by using the the method of constructing an ellipse withseveral arcs and presents a new and simple method fOr geometry moulding of scroll case sur-face.

蜗壳是水电站的重要部件之一，本文以包络理论推导了蜗壳曲面方程；并采用分段圆弧构造椭圆的方法构造了变径椭球包络曲面，为蜗壳曲面的几何造型提出了一种新的简便方法。

The Sun's Parallax: The size of the earth as viewed from the Sun and expressed as an angle and generally taken to be 1/2 the diameter at the equator is 8.9008091 seconds of arc using 91848,817 miles as the mean distance to the sun and 3,963.4914 miles as the equatorial radius.

太阳的视差：作为太阳和地球的大小看作为一个角度表达，普遍采取的是1月2日在赤道，直径为8.9008091弧用平均91848，817英里秒距离太阳和赤道半径3，963.4914英里。

At the time of RHESSI's measurements in 2004, ridges increased the sun's apparent equatorial radius by an angle of 10.77 +- 0.44 milli-arcseconds, or about the same as the width of a human hair viewed one mile away.

在2004年RHESSI进行测量时，这些脊让太阳的赤道半径增加了10.77±0.44毫角秒，相当于1英里(约合1.6公里)外看到的人的头发的宽度。

A circle of radius r is inscribed in an equilateral triangle ABC.

triangle 一半径为 r 的圆内接於一等边三角形 ABC 。

Variational regularity of the normalized equivalent radius( r norm= r/Λ) with normalized frequency is found out for different photonic crystal fiber parameters.

该分析和结果可为利用有效折射率法分析光子晶体光纤时等效芯半径的选取提供一定的理论依据。

It will give you 15% of the cost of any opposing unit or structure you destroy that is in the Eradicator Hexapod's radius (the circle that you see when you have the Eradicator Hexapod selected).

它将回收自身周围一定范围内摧毁的任何敌方单位或建筑价值的 15％给你（有效范围在你选中根除者时可以看到）。

Phase velocity error caused by position error of microtremor observation array is computed under different conditions such as two different dispersive phase velocity models of Rayleigh wave, three kinds of radius, 19 kinds of observation position mode and 6 types of position error.

为研究地脉动观测台阵中观测点之间的定位误差带来的影响，计算了在两种瑞利波频散模型、3种不同的圆周半径以及19种观测位置等多种情况下由6种定位误差引起的瑞利波相速度相对误差，结果表明：由于圆周上观测点数目有限，在不存在定位误差时，相速度误差也是存在的，随观测点位置的不同，相速度相对误差存在差异，其最大值约为最小值的3倍。

Less obviously, the smaller the radius, the stronger the gravity and the greater the escape velocity, too.

容易忽略的是，行星的半径越小，它的引力和逃逸速度也变得越大。

You know of course that the volume of a sphere goes up as the cube of its radius-according to normal Euclidean geometry ?

你自然知道球体的体积是随着它的半径的立方而增长的-根据通常的欧几里德几何知识的？）

She would see the same number of rulers involved as did observer A, and so would likewise conclude that the ratio of circumference to radius did not conform with Euclidean geometry.

她将看到和观察者 A 一样数量的尺子。所以同样的，将可以做出这样的结论：圆周和半径的比率将和欧几里德几何不一致。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.

你一定是病了，你的脸色苍白。
