圆盘

The old technology and equipment in the curve of columnar ,plane and cambered coiled pipes for circular pipe-coiled pipes and half pipe-coiled pipes were very complicated.

原有的圆管盘管和半管盘管中的柱面螺旋盘管、平面盘管和曲面盘管的结构繁杂、弯制质量差以及弯制工艺工装造价昂贵。

The excavation surface model of the composition geologic strata for the shield machine was established, in which the soft soil and hard rocks are taken into account simultaneously. In terms of the cutting mechanism of the individual disc cutter and drag scraper, the total bending moment model on the cutterheads of shield machines was proposed. The bending moment behavior was discussed when the shield machine excavates in the composition geologic strata.

针对盾构机在掘进过程中上软下硬的复合地质结构，建立了其刀盘截面圆模型，基于单个切削刀和盘形滚刀的切削机制，建立了复合岩土层掘进时刀盘平面内总弯矩分析模型，分析了与刀盘接触的撑子面内，不同软土面积分数的复合地质条件下，刀盘旋转掘进过程中的弯矩动态特性。

The disc has a radius of about 12 billion kilometres, roughly twice the size of the Kuiper belt.

这个圆盘半径约为120亿公里，论大小大致是柯伊伯带的两倍。

Forming a corresponding complete set with other farm implements, it can take rotary tillage with sitting, plow and plough with sitting, plough with walking, disc plough, ditch, harvest, lawn repair, transport.

双力牌手扶拖拉机集牵引、驱动和固定动力输出为一体，操作轻便灵活，通过性能良好，适用于水田、旱地、果园和丘陵地带作业，与相应农机具配套可进行座乘旋耕、座乘犁耕、步犁耕、圆盘犁耕、开沟、收割、草坪修整、运输作业，还可作为抽水、喷灌、脱拉、磨粉、发电、饲料加工、破碎等固定动力输出。

Echinoderms characterized by five arms extending from a central disk.

从中间圆盘上伸出五只臂的棘皮动物。

Well, 20th century astronomers would classify it as a Planetary Nebula ... but it's not a planet either, even though it may appear round and planet-like in a small telescope.

在21世纪，天文学家会将它分类为行星状星云，但是实际上它也不是行星，只是用小型的望远镜观测时，它具有行星的圆盘状外观而已。

Secondly,we improved the related inclusion region for it,which is based on the eigenvalue inclusion region theories such as Gerschgorin theory and ovals of Cassini theory.

其次，基于齐次特征值问题诸如Gerschgorin圆盘定理及Cassini卵形域等特征值包含定理，我们对于矩阵非齐次特征值问题的包含域问题做了一些相应的讨论。

Final accumulation of planetary-sized objects is generally believed to come from the gravitational relaxation of the disk of planetesimals.

行星大小的天体的最终积累成功，一般认为归因于星子圆盘的引力弛缓。

RE : when a baby has a few teeth , he can pull the nipple of an old , tired pacifier off the disk or chew pieces out of the nipple .

当宝宝长出几颗牙齿的时候，就会用牙把老旧的咬圈奶嘴从拴着的圆盘上拽下来或把它咬碎。

The ZDP type of H.C.refiner is H.C. pulping equipments to have substituted for imported one.My design is comprehensive the characteristics of Austria,Sweden and Finland etc.Also combine our country environmental protective factor.

描述： ZDP型高浓磨浆机是我公司综合奥地利、瑞典、芬兰等国先进圆盘磨设计特点，结合我国国情研制的保型替代进口的高浓度制浆设备。

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。
