the rule of refusing testimony assumption in Chinese "Some Provisions of the Supreme People s Court on Evidence in Civil Procedures" can not reflect the basic features of assumption and leave too much space to the discretional evaluation of evidence which blocks realization of its advantages such as benefit litigation economy.

The form and mechanism of inference of information understanding,semanteme structure of rule knowledge and production process of new knowledge is discussed ;the memory matrix、computation rule of semanteme truth value and confidence factor of recognition reasoning are established.

Learning algorithm model of constructive PONN based on knowledge rules;

After analyzing the defect and shortcoming of current pipeline check software,the domain-driven design method and UML are introduced to review the check rules,then the pipeline check knowledge rule base capable of customization and its reasoning engine are put forward,finally checking the all-sided investigation pipeline data and its vector data combining with GIS intelligently is realized.

Aim at the workflows as be modeled with knowledge rules,how to keep the reliability of the user defined knowledge rules,workflow model,simulation platform building and simulation engine are studied in this paper,find out the bugs by using visual instance display and statistic technic.

This paper mainly introduced realizing the regular knowledges of″expert system of dam safety monitoring″with VC++for Windows.
