In the aspects of research method, we took the method of preparing sol at first and then impregnating the wood to obtain ceramic-wood composite; this method made the wood use efficiently and increased the wood's weight gain percent. The ceramic-wood composite with performances of well decay resistance, dimensional stability, effloresce resistance and high strength was obtained by importing the cymene to the net of gel as the result of co-hydroxylation between MTES and TEOS. Making use of XPS ,we found that the apex of Si2p、O1s、C1s had evident chemical shift , which validated the existence of Si-O-C bonding.Key Words: Sol-gel, Ceramic-wood composite, Modified sol, Ecomaterials

In this thesis, we implement a computational procedure to categorize and classify 3-D objects from their contour under a simple environment. First, we use foreground detection, Canny edge detection and speedy GVF snake to obtain the object's contour. The contour is then used to establish the object's features. Two databases are built using methods which compute similarity by modified aspect-combination algorithm proposed by Cyr and Kimia and new proposed aspect-combination algorithm. By using these two databases, we recognize 3-D objects using four recognition methods and compare their performance. Finally, a conclusion is made that our newly proposed algorithm is better than the modified algorithm proposed by Cyr and Kimia.
