查询词典 radius

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。

At the second step, the size of the cutter is computed by the minimum concave radius of curvature estimated by the Euler formula.

根据欧拉方程估算零件的最小曲率半径以确定区域补加工的刀具半径，用二分法估算用于清根补加工的一系列刀具直径。

Thirdly, on the base of the existent error estimate of elliptical Galerkin projection operator, obtain semi-discrete and complete-discrete error estimates betwent EFG solution and exact solution of parabolic partial differential equation. Semi-discrete error estimate show that the rank of r is accordance with the approximation rank of subspace S_h. Complete-discrete error estimates show that it not only have relation with radius r of domain of influence, but also have relation with the step length of time variable and the way of discrete.Lastly, give typical examples and draw up procedures of MATLAB.

再次，在"椭圆Galerkin投影"算子的误差估计的基础上，对用EFG法解抛物型偏微分方程的EFG解与精确解之间作了半离散和全离散的误差估计，半离散的误差估计表明所给出的误差界限关于r的阶是与子空间S_h的逼近阶相一致的，全离散的误差估计表明所产生的误差不但与影响域半径r有关，而且与离散时间变量的步长τ及其离散方式有关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
