At this point we are shifting to question two, since the problem is no longer, or not only, a physical one, but rather one that concerns the very nature of creative activity, of the reading process, and in order to unravel this skein of questions we have first of all to decide what we mean by a hypertextual link.

就此而言，我们正在转向第二个问题，因为问题已不再是，或不仅是一个物理问题了，而是一个关系到创造性活动真正天性的问题，关系到阅读的过程，为了解开问题的谜团，我们首先要判断的是，通过一个超文本的链接，我们意欲何为。

When the sojourn time of deteriorating state, inspection interval and maintenance time are the stochastic variables which follow the general distribution, the phase-type approach is proposed to preserve the analytical tractability of the transition probability matrix. To solve the problem that the PH distribution changes the state space of system, the value iteration algorithm for the semi-Markov decision process is improved to get the optimal inspection and maintenance policy.

This thesis expatiates on the theory and architecture and primary content of Reusable Design technology and Reusable Process Design technology, study the feasibility and practicability of some important technology about Reusable Process Design, adopt a special knowledge representation to describe reusable process design information and make use of "FenHua "to realize knowledge acquisition about fuzzy knowledge.Craft database system is the mostly important support of CAPP (Computer Aided Process Planning) system. To some extent, the essence of process design is a process that craft data is visited, used, dealt with and generated. This thesis expatiates on data base design technology. Based on the detailed analysis of the craft data"s characteristic and sort and the craft database"s component part, the author build craft database through detailed conceptual design and logical design and physical design for data base.the application and research of Web database technology becomes increasingly wide, which can make a close combination between Database technology and Web technology.
