摘要：为进一步说明之前的文章,提出了支持面向特定系统表现特征(system manifestation feature,SMFs)的信息管理和构成系统模型编程的信息模式构造(information schema construct,ISCs)。首先,简要介绍了(1)利用SMFs进行具体化设计的一般过程,(2)创建基因型和表型SMFs的步骤,(3)表型SMFs实例化的具体步骤,以及(4)系统模型管理和处理的步骤。接着,讨论了表型SMFs实例化所需的信息块,提出了为实现SMFs实例化而设计的ISCs。然后,讨论了与系统建模相关的信息管理问题。在研究方法上,系统建模包括(1)在模型空间中放置表型SMFs,(2)针对所需架构和操作,组合所放置的表型SMFs,(3)参数赋值以及约束条件符合程度检查,以及(4)在基于SMFs的数据仓中存储系统构建模型。研究的最终目标是开发一个支持信息物理系统(cyber-physical systems,CPSs)建模的基于SMFs的工具箱。

摘要：分析正螺旋面的空间尺寸特点,将计算下料方法和三角线法相结合,计算组成螺旋叶片的各个空间四边形单元的展开尺寸,将四边形单元的展开图依次拼接即可得到螺旋叶片的展开图。用VisualC++编程,能够快速、较精确地展开各种规格的正螺旋面(包括圆台形螺旋),绘制近似展开图。同时得到DXF文件,供AutoCAD直接调用以便输出下料图。最后给出了设计实例。
