【摘要】 本文对计算机信息电磁辐射模型计算及实测产生的３Ｄ数据集进行可视化处理，生成其矢量场的可视化图象，有助于人们理解与分析辐射场的分布情况，发现通常通过数值信息发现不了的现象，帮助人们摆脱直接面对大量抽象数字组合成的复杂形态，而很难发现其内在本质的局面，提高研究水平与效率。更多还原

【Abstract】 This paper describes the methods and characteristics of an interactive visualization systemwhich deals with the 3D data sets derived from caiculation on computer electromagnetic radiation modelsor measurement.The system is helpfuI to us to comprehend and analysc the distribution of the radiationfield,and we can find much more phenomena which can not be found from data information. In this way,we can work efficiently and free ourselves from the situation that we always handle enormous data infor-mation but can not find its essence.更多还原
