This paper points out that the functions of subroutines and parametric programming of the NC system can complete machining of some special parts.

指出利用数控系统的子程序和参数编程功能可以完成一些特殊零件的加工。

In this paper dimension-chain is used to calculate the last effective dimension formed under the influence of tolerances and other distortions. Feature modeling is applied to construct the three-dimension mode of the parts in solidworks. Based on the parametric design function, simulation of assembling result is realized by making use of VB to develop Solidworks. The accomplish of variable parametric design system in tolerance designing is realiazed.

运用尺寸链技术计算出零件在公差及其他变形影响下的最终作用尺寸，利用solidworks中特征建模方法建立起装配体的三维模型，并根据该软件的参数化设计功能，利用VB对其进行二次开发，模拟了装配结果，实现了变参数设计方法在公差设计评价技术上的应用。

The design,application strategy and key technology of the design subsystem based on feature parametrization for Crankshaft are discussed in detail.

着重讨论了零件基于特征参数化设计的设计思想、实现策略和关键技术，对建立微机CAD/CAM集成系统具有一定的参考价值

Main functions in this system are as follows:(1) Establishes the project database of punching die initially;(2) Parametrization design of major parts-,(3) Three dimensional model and assemble of punching dies;(5) Moving simulation of punching die system.

如果你有一个马勒零件编号您无法确定请与我们联系，以便我们研究的一部分。

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。
