说明：  如何开发OPC Server.OPC主要适用于过程控制和制造自动化等应用领域。(this paper teach us how to make OPC Server.The main useful to use OPC is contoel.)

不错的一个VB控件。轻松读取DXF并绘图（有源代码）。程序比较简单，适合初学者(READ DXF FILES)

说明：  功能，利用正交表安排实验称为正交实验设计，该程序是对正交实验的结果，运用方差分析表和F检验个因素对实验结果是否有显著影响。程序是针对不考虑个因素的交互作用的正交设计编写的。(functions, the use of orthogonal arrangement known as orthogonal test experimental design, the procedures of orthogonal experimental results, using analysis of variance table and the F-test factors in the results, is there a significant impact. Procedures are targeting the factors to consider the interaction of orthogonal design prepared.)
