圆周半径

In the CVB-PIV system,the image of astatic particle reflection is a circle,whose center represents the in-plane position of the particle andradius is equal to the displacement of bias related to the out-plane position of the particle.

同时，通过CVB-PIV对单个或多个粒子的静止、直线运动、摆动和圆周运动的研究，以及对平面镜角速度等参数对于粒子影像的影响和粒子面外位置与粒子影像偏移量对应关系的探讨表明，静止粒子的影像是一个圆，圆心坐标与粒子的面内位置相对应，圆的半径就是粒子影像的偏移量，与粒子的面外位置一一对应。

Bohr radius was the radius of the circle in which the electron moved in the ground state of the hydrogen atom, according to the Bohr theory.

根据玻尔理论，玻尔半径是在基态氢原子中电子运动的圆周半径。

"Cardioid:a heart-shaped plane curve, the locus of a fixed point on a circle that rolls on the circumference of another circle with the same radius."

心脏线：一种心形的平滑曲线，圆周上一固定点绕另一具有相同半径的圆的圆周转动的轨迹。

A line segment that joins the center of a circle with any point on its circumference.

圆半径：将圆心与圆周上任一连接起来的线段

Is the centre of a circle of radius 1 and X, Y are points on the circumference.

circle 利用蓝实线画半径为 r 的圆周线。

The radius of a circle is the distance from the centre to the edge.

圆的半径是圆心到圆周的距离。

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。

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。

Since the distribution uniformity of the light energy of the system is satisfactory on the circle of 0.5～10m radius and the beam path of the system offers an advantage of invertibility, it can be used in the fuse of the missile with the feature of WFOV emission and reception.

由于在半径为0.5～10m的圆周上光能量均匀性非常好，且系统光路具有可逆性，因此可用于大视场发射和接收的导弹引信中。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
