This paper introduces the design and implementation of a semantic concept based video retrieval system,which consists of shot boundary detection and key frame extraction subsystem,semantic concept detection subsystem and user retrieval subsystem.

In this paper,a novel approach to semantic concept detection based on local color-spatial feature is proposed.

1-2003 sampling procedures for inspection and GB/T14437-1997 monitored sampling procedures for inspection in physical testing and chemical analysis at Liangang was introduced.

A point of view about which Physical testing and chemical analysis is a part of important composition in materials research has been given, by the discussion on normally and living example for properties of materials which can determined the interior microstructure, and relation to the properties is an important basic reseach in materials science.
