工件

It is absolutely necessary that we should study the process of radiant heat transfer in heat treatment furnace.

工艺中起到对需要热处理的工件进行加热、均温的作用，是一个十分重要的热工设备。

This platform controlled bycomputer, completing work table's plane movement at x-y direction use stepmotor,reading data of accessory position use sensors, processing image use CCD camera.

该平台受计算机控制，用步进电机实现载物台x-y方向上的平面移动，用传感器实现对工件位置的数据读取，用CCD摄像头实现图像输入。

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .

理论分析和试验结果均表明，采用自由过渡的熔滴过渡形式进行焊接，工件始终处于焊接电弧的加热下，在高速焊接时，熔池不能及时冷却，熔池明显拉长，由扰动引起的振动波长大，当熔池的拉长达到一定程度时，会发生液体金属的失稳和颈缩的现象，造成驼峰焊道。

The influence of thedifferent parameters, such as blank-holder condition, thickness of blank sheetand material pattern on the wrinkle and the crack is analyzed. FLD is used tojudge the crack on the multi-point forming process successfully. The predictionof crack accords with the experiment ones, which shows choosing the properparameters can eliminate or restrain the defects, and also benefits the MPFtechnique and the shaping analysis.

本文对使用弹性介质和无弹性介质的多点成形过程进行了对比，指出使用弹性介质时在满足成形精度的前提下可以明显改善工件的成形质量，并通过对不同厚度和弹性模量的弹性介质对压痕的抑制作用进行了对比分析，探讨了最佳的弹性介质参数。

加工工件的可视图像允许更快更有效的检查程序结果。

Apply to the type of disc, cylinder-type, a square inside and outside of the workpiece surface blasting mass production, such as handicrafts, glass shade, Bu Zhanguo, flashlight, Pan, stainless steel washbasins, helmets, gear, and other communications equipment.

适用于盘类、圆柱类、方形工件的内外表面喷砂批量生产，如工艺品、玻璃灯罩、不粘锅、手电筒、烤盘、不锈钢洗手盆、头盔、齿轮通讯器材等。

These aggiornamento machines guarantee machining precision and quality of each workpiece, which is the base of guaranteeing assembling quality of machine.

这些现代化加工设备的引进，确保了每一工件的加工精度及质量的要求，为保证产品装配质量打下了坚实的基础。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
