可视化数学模型及动态演示系统的初步研究与应用

为克服传统数学模型显示不直观的缺陷，采用FORTR AN和VB，VC语言混合编程技术，研制了平面二维可视化数学模型及动态演示系统。该系统能实现计算全过程的可视化，能进行2D，3D图形显示和动态演示。采用该系统，对地形、流态复杂的长江口南北支河段进行了数值模拟。结果表明：该系统界面简洁，操作方便，显示直观，功能强大，大大提高了数学模型解决实际工程问题的效率。

Preliminary study and application of a visual mathematical model and dynamic display system

In order to solve the question of indirect displaying of traditional mathematical model, a planar 2-D visualization model and dynamic display system is established by the mixed programming languages of FORTRAN and VB，VC. It can provide visualization during the whole calculation progress, and can give 2-d and 3-D displaying and dynamic demonstration. It has been carried out successfully on the north and south river reach of the estuary of the Yangtze River. Results show that the window is clear-cut, operation convenient, displaying direct, and function powerful. So it improves the efficiency of solving project problems with mathematical model greatly.
