Science and Technology, Nanjing 210094, JiangsuAbstract : The carbon gradient of carburized case of parts can be predicted by using the finite difference method.

摘 要：零件渗碳后渗层的碳浓度分布可以用有限差分法预测，而碳浓度的高低决定了工件淬火后的硬度。

The hardness of carburized and subsequently quenched parts will be dependent on the carbon concentration in carburized case. Based on experimental data, variation of the

根据试验数据建立了马氏体含碳量与硬度的函数关系，预测了圆柱形工件渗碳后的碳浓度布和淬火后的硬度，硬度的预测结果与试验结果相吻合。

Of metal, non-metallic, deburring, edge, chamfered, polished bright, and strengthen the workpiece surface during the electroplating, chemical surface treatment prior to finishing treatment.

Unfortunately, coolants create high coats in production and can be hazardous to the environment and human health.

当今机械切削加工领域大量使用切削液，目的是为了在切削加工过程中冷却工件、刀具和机械设备，此外还可以降低摩擦力和促进切屑排出切削区，但是由于使用了切削液，增加了生产成本，同时对环境造成污染，损害人们的身体健康。

For the general model with rooted forest precedence constraints jobs or series-parallel digraphs jobs, the optimal algorithms are presented.

对增长率与基本加工时间相关且工件具有有跟森林约束和有串并有向图约束的的单机问题进行研究，分别给出了最优算法。

According to the numerical simulative results, the gear form curves during the die expansion and the gear elastic recovery are plotted respectively.

Regulation by the side of the block-pressed support, so that the supporting block to maintain good contact with the workpiece: by regulating the extension units in the handle, change or reduce the concentration of cutting lathe and extension units in the large gap between the extension units: in order to break them down.

可通过调节上侧支承块的压紧力，使支承块与工件保持良好接触：通过调节中拖板手柄，改变切削浓度或减少车床大拖板和中拖板间的间隙：从而加以消除。

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.
