冷轧钢好还是不锈钢好:谁能帮忙翻译一下！谢了！！

The design is to process parameters of the key groove, the shaft coupling, the gear and the bearing. It makes use of the Access database, VBA embeded in Auto CAD 2004 and Auto LISP programs. The main idea is to select and design regular structures by VBA, generate related parameters by searching the Access database in exemption of the trouble of seeking among many materials, and at last form a readable file including the plotting data. Afterwards utilize Auto LISP and draw the plot according to the readable file. Thus the procedures from design of pieces to the plot drawing are once finished. The designing and drawing time is much saved.

The design is key slot, shaft coupling, gear and bearings for the design parameters of the design process, the application of the Access database, inlay in Auto cad 2004 and the Auto lisp VBA procedures, the main design concepts : using VBA common structure for the selection and design, Access databases and enquiries generated through relevant parameters instead seek out a large amount of information generated readable final text documents (including the document mapping the relevant data used), and then using Auto lisp procedures required readable text documents commonly used in the design of the structure direct mapping. Thus, a mapping from parts of the design to complete, greatly improving the design and mapping time
