These algorithms have laid a foundation for setting up the basic data in MES. The five elements BOM definition used to describe product structure is given in order to reduce BOM quantity and realize BOM consistency effectively. In addition, the mapping algorithm is implemented by five elements BOM, which can make them link seamlessly to transforming from product structure model to procedure model with workflow. It provides a technical foundation to control and management in the product life cycle. And it also meet requirements which include the identicalness, integrality, integration of BOM data in the product life cycle.
介绍了BOM的基本概念,提出了EBOM/PPBOM向MBOM映射的算法和多BOM数据死锁的检验算法,为快速建立MES中的基础数据打下了基础;给出了五元组BOM对产品结构进行描述的柔性定义,可有效减少BOM数量和实现BOM的一致性;提出了基于五元组BOM的产品结构模型向Petri网过程模型的映射算法,从面向产品结构的建模转化为面向过程的Petri网建模,从而为产品的全生命周期的控制与管理提供了技术基础,满足产品生命周期中的BOM的一致性、完整性和数据集成性的需求。

The study indicates: the pore's and particle conglomerate's change are all linked together under load; with the load increasing, the arrangement of the particle conglomerate is developed to the immethodical state and the pore's directionality is better than the particle conglomerate's; through changing its own form and adjusting its arrangement under load soil mass transform piece by piece into the steadily load-bearing form and its deformation develop towards the trend that the deformation reduces.
研究结果表明:孔隙和颗粒集聚体的变化存在一定的关联性;随着荷载的增加,颗粒集聚体排列向着杂乱无序的方向发展,孔隙定向性优于颗粒排列;在荷载作用下,土体通过自身形态的变化,排列形式的调整,逐步向稳定的承载形式过渡,使变形向逐渐减小的趋势发展。

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。
