| 摘 要： | 为了对目标DXF模型的电磁特性进行计算,分析了此类模型数据文件格式,研究了读取和分析这类模型数据的方法。针对DXF模型的质量分析方法,提出了一种更简单的以三角形最短边与最长边之比定义的三角形质量因子,用该因子对实例模型进行了分析,得到的分析结果与文献1,2]中所采用方法的结果一致,证明了边长比因子的正确性和有效性;通过对DXF模型的分析,证明了该模型的剖分质量较高。

| Abstract: | In order to calculate electromagnetic characteristic of target's DXF models,the model's data format is analyzed,the reading and analysis methods are studied.A sort of simpler quality factor,which is defined as the length ratio between the shortest and the longest edges,is proposed.The real DXF model's quality is analyzed according to the factor and the gained result is as good as in References 1 and 2,the correctness and validity of the factor are proved.Through analyzing,the better meshes generating quality of DXF model is proved. |

| Keywords: | DXF model triangular mesh triangular quality factor electromagnetic characteristic geometric modeling meshes generating |
