On the basis of uniform data model, the sub-machining process planning ofpart is auto-created by means of analytic hierarchy, The step decision methods basedon AHP is put forward.6. For the design/manufacture information in the course of product life cycle, thetree structure based on Object-Oriented and static model based UML are founded. Themethod of establishing design/manufacture information management system isbrought forward. The commercial PLM software—SmarTeam is regarded asdevelopment platform, on basis of which, the design/manufacture informationmanagement system is built, and the multi-view mapping technique ofdesign/manufacture information model is studies.7. A computer-aided CAPP platform based on PDM/PLM is founded, and itsstructure, function, work flow is illustrated. Some example of the system areintroduced.

Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. Linux, like all Unix variants and most modern operating systems, provides preemptive multitasking. In preemptive multitasking, the scheduler decides when a process is to cease running and a new process is to resume running. The act of involuntarily suspending a running process is called preemption. The time a process runs before it is preempted is predetermined, and it is called the timeslice of the process. The timeslice, in effect, gives each runnable process a slice of the processor''s time. Managing the timeslice enables the scheduler to make global scheduling decisions for the system. It also prevents any one process from monopolizing the processor. Bs we shall see, this timeslice is dynamically calculated in the Linux process scheduler to provide some interesting benefits.

多使命操作体系可化分为两类：非抢占式多使命以及抢占式多使命所有像Unix的变种体系以及很多现代操作系同同样，Linux提供抢占式的多使命模式在抢占式多使命模式中，调度步伐决议啥子时候进程中止，新的进程能够开始得到运行这个被强制挂起的动作就叫做抢占进程在被抢占前，运行的时间是预知的，这个时间叫做时间片究竟上，时间片是为每一个运行态的进程分配处置惩罚器的时间的一片管理时间片，使能调度步伐为体系做好整个的局面：胸怀～调度决议时间片也能阻止任何一个进程垄断处置惩罚器正如我们看到的，在Linux进程调度步伐中时间片是蜂蜜面膜动态计算出来的，这样带来很多利益

The story of these stamps began on may 14,1918,the day after they were placed on sale.in washington,d.c.,w.t.robey,a man interested in stamps,decided to buy a sheet of the new stamps and so went to the new york avenue branch post office in washington.when the clerk handed him a sheet of the stamps robey noted that they were poorly centered.he looked at other sheets and found that none was well centered.the clerk asked robey to return later in the day when more stamps were expected.

关于这些邮票的故事发生在1918年5月14日，该日是它们开始销售的第二天。在首都华盛顿，一个集邮爱好者，罗比，决定去买一整版新邮票，于是他来到华盛顿市纽约大街的邮政支局。当职员递给他一版新邮票时，罗比看到它们的中心位置很差。他看了其它几版，没有一个摆正中心位置。职员告诉罗比当天晚些时候来退换，估计那时有更多邮票到货。

Guided by the theories of exocentric-endocentric construction and decategorization of nouns, the main purpose of this article is to study the phrases which are composed by nouns or centered by noun or nouns but not belonged to the category of endocentric constructions in modern Chinese. These noun-centered exocentric constructions have almost lost all of the categorial characteristics of nouns and played the roles of predicate or adverbial modifier or complement in Chinese clauses.

本文主要结合离心结构、向心结构理论和名词非范畴化理论；研究现代汉语中以名词构成或者以名词为核心的、结构上又不属于向心结构的短语，这些名核离心结构短语在语法功能上基本丧失了名词的范畴属性，在句子中一般充当谓语、状语或者补语。
