装配

Advantages of prefabrication include the cost savings of mass production, the opportunity to use specialized equipment to produce components, and standardization of parts for quick assembly and erection.

预制的好处包括节约大量生产的开支、提供使用实际材料来生产构件的机会以及样板的快速装配和修建。

The Prescott achitecture, the last core of the Pentium 4, has a 31 stage pipeline.

流水线的工作方式就象工业生产上的装配流水线。

The rotor is then heated and press fit onto a cooled precision-machined one-piece stainless steel shaft and the assembly is then machined and balanced as a unit.

转子经过加热后压入配合进经过冷精密加工的一体式不锈钢轴内，然后机械和平衡设备装配成一个整体。

Interference fit: results in an interference between the two assembled parts--the shaft is larger than the hole, requiring a force or press fit, an effect similar to welding the two parts.

过度配合：在两个装配在一起的零件之间或者存在着过盈，或者存在着间隙的配合——轴可以小于或大于孔，但仍在规定的公差内。

The company's primary business is IC component packaging and test and memory module assembly.

公司的主要业务是集成电路封装测试和内存模块装配。

Based on parametric primitive libraries, the function of sequential automatic assembly is implemented. Combined VC++6.0 with UG/Open API functions, UG/Open UIStyler, UG/Open MenuScript ect., the automatic modeling and virtual assembly systemfor parallel mechanisms integrated into UG NX2.0 is developed.

结合VC++6.0开发环境，运用UG/Open API函数及UG/Open UIStyler、UG/Open MenuScript等工具，实现了并联机构的自动建模与虚拟装配系统功能，完成了基于UG NX2.0平台的应用系统的开发。

通过分析虚拟装配对产品公差模型的要求，提出了虚拟环境下产品公差混合模型。

A tolerance analysis procedure based on homogeneous transform and Monte Carlo Simulation is proposed in this research. The propagation of variation in 3-D space is treated as propagation of errors during transformations of Cartesian frames, which are set up on the Key Characteristic Points.

通过定义车身装配坐标系统，根据微分运动的原理，建立了计算车身零部件位姿关系的数学模型，对典型公差语义的数学表达进行了研究；并应用蒙特卡洛模拟，对关键特征点偏差传播的统计特性进行了分析。

In the end, all the drawings of parts and assembly are protracted in order to facilitate the manufacture.

最后，为了加工制造的方便还绘制了切割机的所有零部件和装配体的工程图。

And then the motor, frames, pulley, assemble the shaft and housing, and so on.

然后将电机、框架、皮带轮、轴和轴承等装配在一起。

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％。
