This study points out that the basic principle of the graph element assembly design and analyzes the implementation method of the graph element assembly design. It gives the application of the graph element assembly design.

In the system, parametric method based on the graph is used, while users select a graph element, the system can search for adjacent list beginning the selected one, and establish relative constraint equations according to constraint conditions.

Chapter three researches in depth of object-oriented characteristic of bond graph, the expression mechanism of bond graph element in Modelica, and Modelica implementing of bond graph model.

This paper is based on a number of subprogram designs of dimension line graph elements.A systematic research has been made on drawing types of dimension line in engineering graphics. By means of two different ways in design two sets, including thirteen general subprograms, have been worked out respectively, which may be used in drawing most of dimensions including straight line segment,diameter, radius, arc length, angle etc., with different sizes and in all positions in engineering graphics. Each subprogram...

This paper is based on a number of subprogram designs of dimension line graph elements.A systematic research has been made on drawing types of dimension line in engineering graphics. By means of two different ways in design two sets, including thirteen general subprograms, have been worked out respectively, which may be used in drawing most of dimensions including straight line segment,diameter, radius, arc length, angle etc., with different sizes and in all positions in engineering graphics. Each subprogram has been examined on a computer to draw, practise and call repeatedly, and have been memorized in the magnetic disc store of the Computer Station of the Anshan Coking Refractory Designing Institute. The two sets of subprograms have enlarged the function of marking dimensions of the XYNETICS Computer Automatic Drafting System which is advanced in the world at present. It is convenient for call, and can greatly shorten the time for designing programmes. Consequently, the effectiveness will be increased.

In this paper we discuss the compressing technology of computer graph information, which dissect a graph into a series of graph elements. Using this technology,we only needs a few parameters to draw a graph on the screen, so that it makes possible the real-time displaying and reduces the number of memories needed considerably as well. This technology has been introduced in the management and control of a power station by using the APPLE-Ⅱ . But it can also be used in drawing simulating...

Using this technology,we only needs a few parameters to draw a graph on the screen, so that it makes possible the real-time displaying and reduces the number of memories needed considerably as well. This technology has been introduced in the management and control of a power station by using the APPLE-Ⅱ . But it can also be used in drawing simulating graphs for other industry processes by using IBM-PC or other kinds of computers. In this paper,we also present the program flowcharts for the generation of the data format and drawing simulating graphs.

In the past,the language method was often used to judge the pattern of 3 dimensional solids,i.e.they were described by simple graph element and grammer rule.But it is difficult and abstract to express the operational relation of how a graph is formed from certain sub-graphs with the logical or digital operations.For 4 dimensional solids,it is even more difficult.In this paper,with the help of the projection principle of three and multi-dimension in descriptive geometry, and combined with the...
