Element Focusing And Knowledge Reasoning Mechanism Of Extension Detecting

With the rapid development of computer science and information technology, the detection technology has become the key technology for the economic development and scientific progress. For the detection technical flaws, it is inevitable that many detections bog down. To solve the undetectable problems, the extension detecting technology emerges as the times require. It uses the theoretical foundation and the analytical method of contradiction as well as the relatively mature sensor technology to make the undetectable undetectable problem detectable.The extension detecting technology includes four parts, which are key detectable matter-elements distilling, adaptive degree analyzes, focusinging and reasoning mechanism construction, focusing processing. This paper researches on the focusinging and reasoning mechanism construction, which is to construct the reasoning mechanism and use it to get the focusing. The focusinging is actually to work out the core element of the detectable matter-element according to the adaptive degree distributing. So the rationality of the focusing is on whether it can describe all the detectable matter-elements' adaptive degrees to a large extent. In different applications, the essential meanings of the focusing are different.This paper firstly discusses the types of the focusinges and considers them to be one-dimensional, two-dimensional, three-dimensional and multidimensional focusing; secondly puts forward the methods to solve all types of focusing: to the one-dimensional and two-dimensional focusing, connects the adaptive degree with the dependent function to figure out the focusing; to the three-dimensional and multidimensional focusing, constructs an extension fuzzy -based knowledge reasoning expert system and uses the extension reasoning and fuzzy rules to work out the focus; lastly takes the performance appraisal in enterprise as an example to expatiate the process and sense of the element focusing in extension detecting and make prospect of the next reseatch.
