Question

请哪位高手帮我翻译一下一段短文，急用，谢谢！

在液压系统中液压元件是其主要部件，液压元件的生产制造成本及效率在液压系统中有着及其重要的作用。而机械行业CAD的广泛应用对其产生了重要影响。目前的CAD应用情况来看，尚存以下两个问题：其一，CAD工作进展缓慢，成果零散，难以发挥优势。作为CAD平台开展二次开发工作的极少，开发的软件水平也不高，针对性太强，应用局限性很大。其二，现有的大多数CAD软件在用户界面方面存在着 交互困难、操作不便的问题，极大地限制了CAD技术的推广应用。
本文在Autocad的二次开发平台之上，通过使用Visual Basic for Application语言对液压集成块模块进行了二次开发。孔道的生成借助集成块与圆柱或者圆锥之间的布尔差运算得到，使用者只要输入基本参数就能得到。如果是锥孔只要把圆柱换圆锥就可以。每次孔道都会有新的坐标系跟随，作为其基准坐标系，这样就可以得到任意平面的孔道集成块。而剖切只需要直接调用就行，系统会直接跳到AutoCAD2007的主界面中，自动调用剖切命令。模块程序通过使用者输入的命进行循环选择会自动生成三维实体图形供使用者参考修改。

Hydraulic pressure in the hydraulic system components are the main components, hydraulic components of production cost and efficiency in the hydraulic system and has an important role. And machinery industry for its extensive use of CAD had a major impact. CAD Application of the current situation, surviving the following two questions: First, CAD has been slow, sporadic results, it is difficult to play advantage. As a CAD platform for the secondary development of the work carried out very few of the software development level is not high, targeted too great application of the limitations. Second, the majority of the existing CAD software in the user interface there is a cross-difficult question of inconvenience to the operation, which greatly limits the application of CAD technology.
In this paper, the secondary development of Autocad platform, through the use of Visual Basic for Application language Manifold secondary development of the module. With the generation of channel chip with cylindrical or conical difference between the Boolean operator to be, the user as long as the basic parameters can be input. If the taper hole for as long as the cylinder can be tapered. Each channel will have to follow the new coordinate system, as part of its base coordinate system, this can be any two-dimensional channel chip. And cutting the need for direct calls only on the line, the system will skip to the main interface AutoCAD2007 automatically call the cutting order. Procedures through the user input module of the life cycle of choice for three-dimensional entities will be automatically generated for users to refer to modify graphics.
