The finite-difference of governing equations with fourth-order accuracy in the normal direction is utilized in full regions including points close the wall, and is very important for accurately discreting equations.

Canon law is also called "ecclesiastical law"; however, strictly speaking, there is a slight difference of meaning between the two expressions: canon law denotes in particular the law of the "Corpus Juris", including the regulations borrowed from Roman law; whereas ecclesiastical law refers to all laws made by the ecclesiastical authorities as such, including those made after the compiling of the "Corpus Juris".

教会法也被称为"教会法"（强制ecclesiasticum ），但严格来说，有一种略有不同的意义，两国间的表情：教会法是指在特定法律的"法典"，包括法规借来罗马法，而教会法是指所有的法律是由教会当局的作为，例如，包括那些经过编撰的"法典"。

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.
