摘要
本文介绍了应用微机开发的二维流场多媒体动态仿真系统．通过建立数学模型，运用计算机图形学与多媒体的理论和方法，采用面向对象的ＶｉｓｕａｌＣ＋＋语言，解决了流场转换、像素点旋转、流场的连续性及背景音乐及解说的同步性等问题，并对动态图像演示文件进行了压缩编码．仿真了不同方案下海河口的流场的运动，生动形象地展示了其运动的全过程．
This paper presents a multimedia dynamic simulation system of 2 D flow field established in a computer. The mathematical model is established and problems such as the conversion of flow field from Euler system of Lagrange system, the rotation of pixels, continuity of fluid field as well as the synchronization of background music and commendatory are solved according to the computer graphics and multimedia theory. A technique of coding is adopted to compress the image file. The system simulates the movement of the fluid under different schemes in Haihe estuary vividly.
