In the middle of this paper, six kinds of basic Petri net flow modules which conform to Workflow model are put forward. The method of transforming Petri net flow model to XPDL and constructing Petri network using XPDL is given. These establish the base for different modeling method using Petri net. And these extend EJB task engine and Subprocess task engine of distributed Workflow Management System——Flowstep.

These work are mainly based on two assumptions: one is called as the Deeg-Pak assumption, i.e., the crack is assumed to be an impermeable slit and thus the electric field inside the crack is equal to be zero; the other is called as the Parton assumption, i.e., a crack is treated as a permeable cut across that both the normal components of electric displacement and the tangential component of electric field are continuous.

裂纹问题：对于压电介质内的裂纹问题，近十年来人们已做了大量的理论分析工作，这些工作主要是基于两种假设：一种称之为 Deeg-Pak 假设，即假设裂纹为电非渗透的，因此裂纹内的电场等于零；另一种称之为 Parton 假设，即假设裂纹为电渗透的，且跨越裂纹上下表面电位移的法向分量和电场的切向分量是连续的。

This papers is divided into six chapters and seeks to combine heritage buildings and the concept of modern information. The author make a preliminary analysis and research about historical information constitution of heritage buildings. On this basis, we strive to present a new vision to examine and discuss about the conservation of heritage buildings. Throughout the course of the study and exposition, we make Chinese ancient buildings of timbered structure as its main target, and combine with many examples about ancient buildings of timbered structure in Shanxi Province. In this papers, the author combine the abstract information with the concrete buildings closely, and hope to provide a new way of thinking for the study of heritage buildings through this way.

本论文共分为六章，旨在将文物建筑和现代信息概念相结合，并对文物建筑历史信息的构成进行初步的分析与研究，在此基础上，力求以一个新的视角对我们当前的文物保护工作进行审视和讨论，在整个论述与研究过程中，我们以文物建筑中的中国古代木构建筑为主要研究对象，并结合了大量独具价值的山西省古代木构建筑实例，把抽象的信息和具象的建筑紧密结合，希望能通过这一途径为文物建筑的研究、保护等工作提供一个新的思路，以达到抛砖引玉的效果。

In this paper, the space-time finite element theory and its application technologies are studied and discussed. Furthermore the space-time finite element method is used to analyze the transient characteristics of electromagnetism equipments. The work is important to develop the numerical method for the transient electromagnetic field. The detailed work is as follow.In the basis theory of finite element method used in the transient engineering problem, the functional theory and the finite element theory are applied to studied the existence condition of a generalized variation principle, which is the basis of the space-time finite element method.
