在结构上

With the springing up of the Post-structuralism during the second half of the 20th century, constructivist learning theory, by observing the principles inherent in Post-structuralism such as structurelessness, non-focus, non-rationality and relativity, etc., reflects a networked non-structural and relative learning theory.

心理学理论的发展总是与某一历史时期的哲学思想和自然科学的影响交织并行的，学习理论也不例外。20世纪60年代在法国兴起的后结构主义浪潮在方法论上对学习理论产生了深刻的影响，建构主义就是基于这一思潮而兴起的，是一种后结构主义学习理论。

But my analysis of USAir's business was both superficial and wrong. I was so beguiled by the company's long history of profitableoperations, and by the protection that ownership of a senior security seemingly offered me, that I overlooked the crucial point: USAir's revenues would increasingly feel the effects of an unregulated, fiercely-competitive market whereas its cost structurewas a holdover from the days when regulation protected profits. These costs, if left unchecked, portended disaster, however reassuring the airline's past record might be.

不过我对于美国航空业的分析研究实在是过于肤浅且错误百出，我被该公司过去历年来的获利能力所蒙骗，同时过分相信特别股可以提供给我们在债权上的保护，以致于忽略了最关键的一点︰那就是美国航空的营收受到毫无节制的激烈价格竞争而大幅下滑的同时，其成本结构却仍旧停留在从前管制时代的高档，这样的高成本结构若不能找到有效解决的办法，将成为灾难的前兆，不管以前航空业曾经享有多么辉煌的历史。

This paper introduces the software structure and real time process principle of real time NC system, according to the milling process character of NC system and the geometrical modeling method of computer simulation, presents a technique of subdividing roughcasts and data structures which applies to the computer simulation of the NC milling process; and in order to quicken the operating rate and enhance the reality of computer simulation, puts forward a logic algorithm of the 3D milling process of real time NC system which can display the effects of the computer simulation of 3D milling process of real time NC system dynamicly and efficiently in PC, such as the movement of tools, the elimination of materials, the shape changing of roughcasts.

刘景能，蒙艳玫（广西大学，530004）摘要：本文介绍了实时数控系统软件结构与实时工作原理，根据数控系统铣削加工的特点和计算机仿真几何建模方法，给出了适用于数控铣削加工仿真的毛坯离散细分方法和数据结构；为了加快处理速度和增强仿真效果真实感，提出了一种实时数控系统三维加工仿真的逻辑设计算法，即在单CPU机器单线程程序中使用普通软件循环和定时器模拟实现多线程，该算法可以在微机上动态显示高质量的铣削加工过程刀具的运动，材料的去除和毛坯形状的变化等数控加工三维仿真效果。
