圆环

The main component of the celestial globe is a hollow bronze globe, with crisscross grids on the spherical surface, which are used to delineate the exact position of celestial bodies.

整个铜球可以绕一根金属轴转动，转动一周代表一个昼夜，球面与金属轴相交于两点：北天极和南天极。两个极点的指尖，固定在一个南北正立着的大圆环上，大圆环垂直地嵌入水平大圈的两个缺口内，下面四根雕有龙头的立柱支撑着水平大圈，托着整个天体仪。

The Fresnel lens, also known as the dioptric lens, consists of a central glass disk and concentric glass rings or a central glass band surrounded by parallel glass rings.

一个在中心的玻璃圆片和与之同圆心的层层玻璃圆环，或者中间是一个玻璃带，两边是与之平行的玻璃带状环。

Additionally, the top wall has a flexible annular ring formed axially along an inner surface and depending downwardly therefrom and spaced inwardly of the skirt.

另外，顶壁有一个沿其内表面轴向地形成的向下延伸的弹性圆环，并且该弹性圆环向内与环状裙边分隔开。

They can be used when we solve the problem of rotating ring by using the eigenfunction expansion method.

并推导非旋转圆环振动模态的正解，作为旋转圆环解求析解时的特徵函数展开法所使用。

The precise location from the perturbanced ring image is an important step for hemispherical imaging and tracking system targeting object.

在半球成像系统实时跟踪目标的过程中，从受到光扰动影响的圆环像中迅速准确地提取圆环的中心是一个关键。

I believe that the power and important symbolic nature of the ring sculptures could also be successfully conveyed in one monumental "circular" stone and metal sculpture similar to the maquette illustrated.

我相信，"圆环雕塑"的力量与极具象征性的特征应当也能成功地在一个大型金属圆环及石头中得到体现，如图中模型所示。

According to the helix theories of cylinder,the essential factors of helix with torus are analyzed,and the parametric equation of helix on torus is given based on analytic geometry.

根据圆柱螺旋线理论，分析了形成圆环螺旋线的要素，并运用解析几何方法建立了圆环螺旋线的参数方程。

Pipefish out my tweezers, first lock on the fan rotor to chip removed, that is kind of like a circle, a small gap in the middle of the ring, do not lost Oh.

拿出我的尖嘴钳，先把风扇转子上的锁片拆下来，就是那种像一个圆环，中间有一个小缺口的圆环，不要弄丢了哦。

When she came back, she showed me her ring on her ring finger. She was engaged!

当她回来了，她显示了我她的圆环在她的圆环手指。

The theoretical study of round-link chain with notch provides a theoretical basis for structure optimization and safety analysis of the round-link chain.

从理论上对含有缺口的圆环链进行了分析研究，为圆环链的结构优化和安全性能分析提供了必要的理论依据。
