Mainly for workpiece quenching after pit Furnace, box furnace, salt bath furnace and so on each kind of electric furnace heating.

主要供井式炉、台车炉、箱式炉、盐浴炉等各种电炉加热后的工件淬火使用。

Three-phase embed electrode salt bath furnace use the salt class as heating impregnant, according to the different operating temperature, could select different ingredient salt or compound salt, the salt is not electric beforemelting, therefore the salt bath furnace must use the starting-electrode to melt when using, because the electricity bring quantity of heat unceasingly through electric dissolving salt, so can maintain the dissolving state, because of electrode under the electromagnetic effect,make the dissolving saltcycle unceasingly through natural convection and magnetism mix round,therefore can well-proportioned heat workpiece rapidly.

三项埋入式电极盐浴炉采用盐类作加热剂，根据不同的工作温度，可选用不同成份的盐或混合盐，盐在熔化前是不导电的，因此盐浴炉使用时必须使用起动电极溶化，由于电流通过导电的溶盐不断产生热量，故可保持溶化状态，因电极在电磁力的作用下，通过自然对流和电磁搅拌而使熔盐不断循环，故可迅速和均匀的加热工件。

Drawing the Company for the cable industry tower round, round wire, cans, etc. Drawing on the need to wear-resistant parts, introduced from abroad the international advanced level of spraying equipment, to provide users with various types of wear and corrosion-resistant, high temperature , And other special requirements for coating.

本公司针对拉丝线缆行业的塔轮、导线轮、拉丝罐等表面需抗磨损的工件，从国外引进具有国际先进水平的喷涂设备，为用户提供各种类型的耐磨、抗腐蚀、耐高温等特殊要求涂层。

Secondly,based on rigid-body kinematics,the model of degree of freedom was formulated to describe the relationship between the machining requirement and the theoretical constraint degree of freedom .

工件自由度的合理约束是夹具设计的关键，基于定位原理的数学模型，根据齐次线性方程组解结构的性质，首先推导了三个定位方案的合理性判据；然后，基于刚体运动学，建立了描述加工要求和理论约束自由度之间关系的自由度模型；最后，利用典型实例详细讨论了自由度模型及合理性判据的分析应用过程。

The torque me asurement experiment in hand tappin g shows that suitable tapping motion w ith high frequency can remarkably re duce tapping torque,and the dominating parameters in hand tapping are cutti ng angle and separating angle,which laid a foundation for the study on vib ration tapping and its popularization and a pplication.

对手动攻丝这种极限振动攻丝过程的扭矩测试结果表明，丝锥对工件的低频、低速往复切削作用也可以使攻丝扭矩显著下降。这表明影响手动攻丝扭矩的主要因素不是振动频率或冲击的大小，而是切削角和分离角的大小，这为进一步究明振动攻丝的机理及促进振动攻丝技术的推广应用奠定了基础。

Milling groove machine is used in processing weaving trade in " pin plate " use privately cut machine tool, belong to the modular machine tool, this machine tool have 4 works position and 8 milling heads, can at the same time process 8 workpieces, have higher processing efficiency and processing precision, and can at the same time still realize needle groove and circular arc groove same work position, it surmounted the shortcoming of that machining process complex, processing efficiency low and process precision do not be in height of the processing of pin plate beforetime, so it have better application prospect.

铣槽机是用于加工纺织业中&针板&的专用切削机床，属于典型的组合机床，该机床具有四工位、八铣头，能同时加工八个工件，具有较高的加工效率和加工精度，同时还能实现针槽与圆弧口槽同工位一次完成，克服了以前针板加工中加工工序复杂、加工效率低、加工精度不高的缺点，有较好的应用前景。

In addition, the protection of the workpiece treated by the copper, not bare hand contact, so as to avoid pollution of the hands sweat rust.

另外，工件经铜保护处理后，不可裸手接触，以免手汗污染生锈。

But CMP technology can obtain the glabrous and smooth plane in virtue of mechanical grinding and chemical eroding.

而化学机械平面抛光技术是借助机械磨削和化学腐蚀的共同作用而使工件表面形成光洁平坦平面。

The machine tool (10) comprises a machine frame (12, 14), or a body, a work piece carrier, with a rotation shaft (38), at least one digitisation unit (46), at least one machining unit (52) and an electronic arithmetic and control unit (50) for all drive lines.

该机床(10)包括一框架(12，14)，或一机身，一具有旋转轴(38)的工件输送器，至少一个数字化单元(46)，至少一个机械加工单元(52)和驱动所有线路的电子计算和控制装置(50)。

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。
