摘　　要：该文将颜色映射与点图标映射方法相结合,最终实现了旋风分离器速度场可视化。为寻求设备中的物质的运动规律,需要将速度场表示出来。点图标方法是最简单最直观的矢量场映射方法,虽然矢量的方向可以被直观、准确的表示,但用图标的大小表示矢量的大小,极易产生视觉混乱,在旋风分离器内的速度场可视化中,将点图标映射方法与颜色映射相结合,使用VC＋＋与Open GL成功实现了旋风分离器内的速度场可视化。This paper focuses on intensively study in Visualization of Vector Field in order to realize Vector Field Visualization of the Cyclone Separator. The algorithms that combining both arrow plot mapping and color mapping was applied to realize Ve- locity field Visualization of The Cyclone Separator. In order to find the rule of flow ,velocity vector should be imaged. The most simple and obvious way to visualize a velocity field is arrow plot mapping arithmetic. However, the output imaging was confus- able. Arrow plot mapping arithmetic with color was applied to Velocity field simulation of The Cyclone Separator. Using VC~＋ and OpenGL the perfect output imaging was obtained.
