摘　　要：用有限单元法数值仿真涡流信号 ,并采用现代科学可视化技术中常用的彩色云图法来显示有限元计算结果。利用该方法对渗碳试件表面硬化截面分布进行了简洁。Finite element method was applied to eddy current signal simulation, and the new method called color contour image applied broadly in modern science visualization was used to show the calculating results. The distribution of the case hardened section of cementite material was described simply and directly by the method.
