转动体

In this model, the small motion of the drum can be expressed by three translations of the centre of mass and three rotations about the inertial axes.

在这一模型中，筒体微振动的6个自由度以质心的3个移动和绕惯性轴的3个转动来表达；框架结构则按有限元法处理。

At first, the dynamic equations of a multibody chain system with prismatic and revolute joints are established according to d' Alembert principle in the form of virtual work.

本文首先从虚功形式的d'Alembert原理出发，建立了具有滑移/转动铰的多体链系。。。

The capacity is large, which can reach above 75% space of the drum. Only 1:1 liquid percentage would meet the technical requirement, the water consumption is small. The liquid in the drum can reach 3/4 level of drum. Therefore the fall of the skins is only 0.7 meter at maximum. The liquid moves as the pattern "8" in the drum, which can reduce skin defects such as grain cracking, loosing and so on.

装皮量大：装载率可达到75%以上，耗水极少，一般液比在1：1以上即可满足工艺要求，机械作用适中，鼓内液面可达鼓径3/4以上，因此皮张最大落差只有0.7m左右，且皮液在鼓体转动时呈∞字型作副运动，可减少裂面、松面、黑漆不掉等质量缺陷。

The gear pump is the volume pump's one kind, by two gears, the pump body and the first top plate is composed two seal spaces, when gear-driven, the gear withdraws the side the space volume to increase since childhood, the vacuum production, inhales the liquid, the gear meshing side's space's volume is small from the big change, but pushes in the liquid in the pipeline.

齿轮泵是容积泵的一种，由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。

Dairyman Crick and his wife, the milkmaids Tess, Marian, Retty Priddle, Izz Huett, and the married ones from the cottages; also Mr Clare, Jonathan Kail, old Deborah, and the rest, stood gazing hopelessly at the churn; and the boy who kept the horse going outside put on moon-like eyes to show his sense of the situation.

奶牛场老板克里克和他的太太，住在场内的挤奶姑娘苔丝、玛丽安、莱蒂·普里德尔、伊茨·体特，住在场外茅屋里的结了婚的女工，还有克莱尔先生、约纳森·凯尔、老德波娜以及其他的人，都站在那儿瞪着搅黄油的机器，谁也没有办法；在外面赶马使机器转动的小伙子眼睛瞪得大大的，对这件事情表现得很关心。

The method of producing the pulley assembly may include modifying as by knurl (22 the outer flat circumferential surface of the metal insert prior to molding the plastic annular body about the metal insert, for clamping, structurally bonding, and resisting relative rotation between the plastic body and the metal insert.

生产滑轮组件的方法可以包括：在金属插入件周围模制塑料环形体之前，改变金属插入件的外圆周表面（例如通过压花（22）），以夹紧、在结构上连接及防止塑料体和金属插入件之间的相对转动。

The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.

内容包括各种形式的接触熔化，可归纳为：在接触形状上可以有凹、凸与平的面，而接触的周长可以是矩形、圆形、椭圆形、抛物线形与弧形曲线；相对运动的类型有固体相变材料在加热容器内熔化，加热体通过熔化固体介质的运动，滑动接触与滚、转动接触；引起接触熔化的原因有温差、压力差、摩擦与粘性热。

Therefore,the elastic resistance is augmented , which makes electric current fluctuate excessively ,the reductor abraded and binded ,and the tyre worn out badly .Thus ,the operation has to be suspended.By means of mechanical property and finite element analysis and calculation of the tyre...

通过力学性能及轮胎有限元分析计算，认为必须改进传统设计使筒体的转动方向与传动装置反向，这样可以在非传动侧均匀设置支撑，以减少主动侧、被动侧的支反力，即减少轮胎的弹性变形阻力矩，达到保护减速机的目的

The systematic error models established in the paper are rigid rotation model, volumetric strain model, homogeneous deformation model and heterogeneous deformation model. The recognition of systematic models is carried step by step from the complex to the simple by hypothesis tests.

所建立的系统偏差模型有刚体转动模型、体应变模型、均匀形变模型和非均匀形变模型，模型的确认通过假设检验方法由复杂模型形式向简单模型形式逐步进行。

Geologic study and GPS surveying indicate that the tectonic motion of the blocks in this region is accounted to be a complex or superimposition of three basic types of motions: southeastward sliding, rotating on vertical axis, and uplifting, but there is difference in the geologic slip rate and GPS rate.

地质研究和现今GPS观测表明：各级块体均存在著SE向或SSE向平移运动、顺时针转动和隆升运动，但量值存在著一定差异。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
