In this paper , we describe a software system called PROLOG - based Toolkit for Expert System design ( PTES ) .

本文描述了一基于PROLOG的专家系统建造工具库PTES的实验系统。

PTES is written in Prolog and extends Prolog 's knowledge processing , capabilities by supporting rule - based knowledge representation and approximate reasoning .

PTES是用PROLOG编写的，该系统根据支持基于规则的知识表示及近似推理对PROLOG的知识处理能力进行了扩充。

Therefore , this paper mainly demonstrates the development and design of windsurfing pumping training expert system ( PTES ), the significance of development system and the key technical issues in realization .

该文主要论述了帆板摇帆运动训练专家系统（PTES）的开发与设计，以及实现的关键技术问题。

The results showed that free phenol a little rose , the content of solid and carbon residue amount and thermal stability were remarkably improved when PTES modified phenolic resin .

结果表明：苯基三乙氧基硅烷水解后改性酚醛树脂，会使游离酚有一定上升，固含量和残炭量都会提高，耐热性提高。

But study on sharing of core competence is very few , the research of expansion model of the PTEs based on sharing of core competence is still the leading research area of the theory .

但是总的来说，对于核心能力共享的研究还很不深入，基于核心能力共享的民营企业扩张模式的研究属于理论前沿。

The reasoning mechanism of PTES can deal with both uncertain facts and uncertain rules in a formal way by employing possibilistic logic and fuzzy set theory as its logical basis .

PTES的推理机制使用了可能性逻辑及模糊集合理论作为其逻辑基础，并以一种形式化的方法提供了处理非确定事实及非确定规则的能力。

In order to handle such attack , we present a method of non-executable page that overloads the meaning of the User / Supervisor bit in the ptes to mean the executable / non-executable status . We have implemented this method for IA-32 processors on Linux kernel .

为了防范这类攻击，提出利用页面不可执行的方法，重载页表项中User/Supervisor位的含义，用来表示可执行/不可执行状态，并在IA32处理器上，基于Linux内核实现了这种方法。
